[INFO] APP - CPU TUNER (Performance and Battery Tool)

For those of you used to SetCPU, NSTOOLS and other apps to manage your custom kernels *plenty on our NS forums* I have found this little tool called CPU Tuner
I ditched NSTOOLS since last version has some stability issues when selecting SMARTASSV2 in my experience and others have also reported some issues with last update (I'm sure it will be corrected in next version).
This made me look for an alternative and found this little gem (only thing this app is not capable off is doing liveOC) but it's ok for me and I'm sure for others that like to run their kernels with default clocks put into kernels by the developers.
CPU tuner has profiles pre-made from easy to advanced features and they can be customized to your needs. I selected the most advanced profile and had made changes accordingly to my own needs.
I'm attaching pictures so you have an idea of what the app is capable of doing, I tested this app using Air_Kernel 3.1 voodoo version by r_data and I was able to get 18 hours of use with about 4 hours and 45 minutes of screen ON... that's a lot my friends. Without this app I was able to get more time about 24 hours but with only 3H30m of screen ON. I still am playing with this app as I need to experience what the best governors and frequencies to use depending on my day of regular use.
Please, feel free to try this app (totally free) and you may like it or you may hate it.
I'm just throwing some own experience here and hopefully you can make good use of this wonderful application.
Some info about profiles in this thread here
SCREENSHOTS:
See below in next post

Note: this app has replaced my app *tasker* which I used to manage CPU and Frequencies
Screenies below:

Hmmmm.... Will have to try this out.

If you do, please throw some feedback about your experience with this app.

Looks pretty decent. Might as well give it a shot.

Well, I am pleased with this app... tons of features to manage your custom kernels... you can set governors and different frequencies... I also see there's a function where you can set days to it....

thank you for introduce and recommand this app.
so cool to control cpu because I don't use any mod of ezekeel's.
Thank you.

Droid 3 4.0.x ROM Comparisons and Other Assorted Goodies [UPDATED w/ ratings]

I won't beat around the bush here: there are quite a few great ICS ROMs available for the D3, but no general consensus as to which on is the best on battery, themes, customization, etc. THAT is the point of this thread...to provide end users and devs alike, with empirical data, side by side, so people can make an educated decision on which ROM to go with. I've been compiling test results for a couple weeks now (still have 2 more ROMs to test), and I've spent a lot of hours on this. I only have a CDMA device however, so GSM performance may vary. If you own a GSM device, and would like to help me out with testing, please PM me, and I'll give you the outline for what I need.
Each ROM will be graded, based on five categories: Performance, Battery life, Lag/Responsiveness, Looks, and Features. Each category will receive a numerical grade of 1-7 (I'm stopping at 7, because that is the number of ROMs currently being developed, and I don't want subjectivity to factor into grading) with 1 being the worst, and 7 being the best. As such, I will add each category together, to obtain a final grade, with the highest possible grade being a 35. As new ROMs are added, I will adjust each ranking accordingly...I will also make adjustments for significant updates, such as AOKP Milestone 5, etc.
I will be dividing ROM reviews by developer, so they're easier to find, and I will also be adding resource links for rooting guides, tweaks, Gapps, and anything else that may be helpful...I want EVERYONE to be able to use this, noobs and OG's alike, and since this is in the General section, I expect you guys to play nice.
*A massive thanks to Hashcode, droidian1441, techno-update, chevycam94, sparkyman216, Cyanogen, kejar, and all the devs who have allowed their work to be ported to the D3, Jrummy16 (ROM Toolbox), zepplinrox (V6 Supercharger), and anyone else I may have forgotten. Without you guys, the D3 scene would be a cold and lonely place...much respect!
#Note: I will not be reviewing non-ICS ROMs. While I respect and admire all the devs still working on Gingerbread firmware, I firmly believe the 4.0.x platform has come far enough to render GB obsolete. If you're here looking for reviews of those ROMs, you've come to the wrong place.
--------------------------------------------------------------------------------------------------------------------------------------
**All test environments were the same, unless otherwise noted. I used the same wallpaper (stock ICS blue "waves" static wall), with Nova Launcher, persistent Search bar on, the stock analog clock widget, Gmail widget, Play Store widget, Calendar widget, and Bookmarks widget on the screens, and a Widgetsoid 2.x switcher in the pulldown. CPU speeds are 1000 MHz min and 1000 MHz max at all times.
About Battery Cycle: The screen was on 100% of the time, with TuneIn Radio running the entire time, to simulate continuous heavy usage. No calls were received during the battery drain cycles, so times should be as "pure" as possible. Three full cycles are done, and the average taken, in order to determine an overall grade. My rule of thumb for extrapolating the battery numbers out is to multiply the average by 2 if you're a power user, by 4 if you use your phone moderately, and 5 or 6 if you're a light user.
About Performance Testing: Performance testing is comprised of three apps, Quadrant Standard, Linpack, and AnTuTu. I run each test five times, drop the lowest score, and take the average, in order to determine a final grade. Linpack scores are all Multi-thread tests, and all AnTuTu tests are run on sd card, not external sd. All results marked in RED indicate the low score, which is being dropped.
For the "Tweaked" performance tests, I utilized V6 Supercharger, with Option 9 selected, NitroLag Nullifier installed, the appropriate services.jar patch flashed, and several ROM Toolbox Pro tweaks applied (will be outlined in a subsequent post).
--------------------------------------------------------------------------------------------------------------------------------------
*Special note to developers: I will not be providing direct download links for your work, nor will I mirror anything. I will be directing everyone to the parent thread for all downloads, and serious troubleshooting help, but I (and hopefully anyone who swings by here) will be willing to offer assistance on general troubleshooting issues (eg. rooting help, flashing assistance, etc.).
Also, please don't take offense to anything written in my reviews... I'm not creating this thread in order to have license to bash anyone's work, but I will try to give a fair and honest critique of how my tests reveal the ROMs are performing. My "Personal Thoughts" sections are not factored into my final ratings; they are simply a summation of my testing experience, and written for the end users, to aid them in making an educated decision. If at any time, you would like me to pull your ROM(s) from my review lineup (for whatever reason), please notify me via PM. As always, continue the spectacular work, as the entire community greatly appreciates it.
--------------------------------------------------------------------------------------------------------------------------------------
That's out of the way, so let's get to what you guys came here for... some comparisons! I'll be adding ROMs as they become available, and devs, if you have a new or existing offering that you'd like me to test and review, please drop me a line.
As always, neither I nor any of the ROM developers take any responsibility for your decisions. If you root, flash, tweak your phone, and it subsequently blows up in your hand, or turns into Anderson Silva and beats you for your lunch money... it's your problem, not ours. Happy flashing!
**Afterthought: It is with much chagrin that I extend a "thank you" to Motorola. Even though you've teased us, provoked us, and downright lied to us about our bootloaders, and continue to hemorrhage new devices like it's your job, you still have the the best device build quality in the market. The Droid 3 is a fantastic phone, and I don't regret buying it for a second...at least I don't think I do...

Homescreen scrolling is smooth with only occasional unresponsiveness, no redraws, and minimal lag when opening apps.
Final Grade 18/25
Personal Thoughts
AOKP is easily the most popular ROM for the Galaxy Nexus, and it's not hard to see why. It offers a ton of native customization options, and has a plethora of excellent themes. Hash's port brings us all the rampaging pink unicorn we can handle...too bad for us, we don't have an unlocked bootloader, because I think this ROM would really scream. As of this moment, AOKP is getting slightly below average benchmark results, and mediocre battery life...once I update and review a newer build, these results may change for the better. If customization is your number one priority, AOKP is the way to go...just be prepared to carry a charger on you at all times.
*A note on themes: Galaxy Nexus themes CAN be applied to these Droid 3 builds. It's as easy as using Root Explorer to extract the contents, remove the framework, re-zip the file, and flash in recovery. Be warned however, that flashing a theme will disable your ability to use USB connection, and will result in force closes every time you attempt to connect. Also, since the framework is removed, certain elements of the original theme will not be present. Search XDA for the few Droid 3-specific themes that are compatible.
*UPDATE: I've updated to the 4-30 (Milestone 5) build, and I have to say, I'm very impressed. Increased battery life is a huge bonus, and the addition of being able to connect to an app by clicking the weather panel (in my case, Accuweather) is an addition that cannot be overstated. I would like to see some better performance results, but the ROM runs just fine. The battery life increase alone may be enough for some more people to take the plunge.

Personal Thoughts
Cyanogen Mod is the well-known standby for many Android users, and CM9 is proving to be just as good as former incarnations. At this moment, it's benchmarking higher, and lasting longer than any ROM tested, and that's before tweaks are applied! The "out of the box" CM9 experience is probably what most people are looking for, but the lack of native theme elements, and the scant amount of performance features may make some people shy away. If you want battery life and performance, but don't care about themes, CM9 is your go-to!

Final Grade 14/25
Personal Thoughts
Overall, Gummy is a nice experience. I'm left feeling a bit empty when it comes to battery life, considering this ROM has fantastic battery life on the GNex, but this ROM has just about everything else you could ask for; it feels like CM9, with some additional bells and whistles. Fair warning here guys...this ROM boasts, easily, the funniest yet most annoying boot animation ever created, and several Nexus owners have shared stories of booting it up while in board meetings, to disastrous results! There is an option to turn the sound off, and if you're a business professional, I fully suggest doing so...there's nothing quite like watching your boss' face turn a deep shade of crimson, when your phone does a hot reboot, and you're faced with an 8bit cat sprite, with a pop tart body, crapping rainbows, and meowing obnoxiously for 20 seconds, while you're making a pitch to an important foreign client, lol. Seriously though, if you like CM9, but want a few more features, and can sacrifice some battery life, definitely give Gummy a go!
**Note: I will NOT be testing the themed versions of Gummy (Grape, Spearmint, Cherry, etc.), as they are simply that- themed versions of the original. If the dev in charge of the port (techno, I believe) has any information to the contrary, and wishes me to do a review, I certainly will.

Smooth homescreen scrolling with little lag, but becomes less responsive after tweaks are applied (may be some conflict with the built-in build.prop tweaks). Search button and Quick Search Bar do not work on this build for some reason.
Final Grade 17/25
Personal Thoughts
At this juncture, Steeldroid v5.1 is still, basically, AOKP with build.prop tweaks built in. That's not to say it's lacking at all, because it's not; if you throw out the Quadrant scores, and focus on Linpack and AnTuTu, this benchmarks as well, if not better than all the other ROMs I've tested so far. Combine that with the second best battery life, and all of AOKP's native theme options, and Steeldroid comes up roses. If you're going to run this ROM however, I would suggest doing so without the tweaks (or maybe just the NitroLag Nullifier and overclock), as there seems to be some conflict between the tweaks chevy has written in, and the ones I've outlined for these tests. Solid battery life, customization, and steady benchmark scores make this ROM one to keep an eye on!
--------------------------------------------------------------------------------------------------------------------------------------
**Quadrant scores in the Tweaked section may/may not be 100% accurate. After applying the tweaks, Quadrant kept giving me a Network Connection error, and had major delays in displaying results, so I'm not sure if the readouts were completely trustworthy.

iOS on the surface with Android under the hood. Has a unique look that will take some diehard AOSP lovers a few days to adjust to, but the UI is clean and easy to use.

Native themes (extensive library, but some still don't render completely), native SMS pop-ups, no additional performance settings, some market apps (Bank of America, AIM, etc.) are not present.
Lag/Responsiveness: Ranking 1/5
"Static" glitch when swiping away recent apps panels, some lag when scrolling through homescreens, but once tweaks are applied, lag disappears.
*Note... I used the stock MIUI Home for testing this ROM, in the assumption that most people who will be using MIUI, will be doing so because they like the native UI, and will not be using a third party launcher.
Final Grade 10/25
Personal Thoughts
MIUI has a love-hate thing going with most Android users; there are some who believe that the AOSP look is what makes Android unique, and reject the iOS-style "bastardization" of the platform, while others love MIUI for its blend of a user-friendly interface with Android's power, its plethora of themes, and its battery life. Unfortunately, since we can't load custom kernels, battery life has suffered on the Droid 3 port- a fact that surprised me greatly, considering the ROM has a CM9 base. The average battery life is the worst I've tested so far, but it can only get better. Sparky works very hard on this port, and is doing everything he can to make it great. If you want a clean, user-friendly interface, tons of themes, and carry a charger on you 24/7 then MIUI is a can't miss!

If you're phone is bricked, or if you need to return to unrooted stock for a warranty replacement (for hardware failure reasons only of course ), you can swing by the2dcour's thread, and get what you need...right here
V6 Supercharger
zepplinrox's scripts are epic! They free up tons of memory, and keep your phone lag free at all times. I fully suggest reading through the entire OP; The worst thing you can do is just take someone's word that something is great, and go with it, without knowing what it's designed to do. His OP is lengthy, but you'll come away with a better understanding of how Android memory management works. In the end, you'll only need three files though; the current V6 version, the wraithdu ICS installer, and the Busybox installer. Any other files are optional (eg. 3G Turbocharger or the patched services.jar). Check his thread here
ROM Toolbox
ROM Toolbox is a great all-in-one tool, that lets you change the values for nearly everything on your device. I fully suggest spending a little coin, and getting the Pro version, as it has additional features unlocked. The tweaks I use in ROM testing are as follows:
Kernel Tweaks
Min Free KBytes: 4096
Dirty Ratio: 90
Dirty Background Ratio: 70
VFS Cache Pressure: 30
SD Boost
Value: 4096
*Additional tweaks, such as VM Heap are optional. When I finally settle on a ROM I like best, I'll be setting my VM Heap to a value between 90 and 100 (76 is the standard).
Overclocking
**I use the "old" Script Manager method, but I'm having trouble finding the original thread. If anyone knows where to find it, please let me know, so I can add a link, otherwise, I'll upload the files, along with instructions sometime next week. Thanks guys.
--------------------------------------------------------------------------------------------------------------------------------------
Helpful Hints for Root Users
First and foremost, I would highly suggest downloading 7zip for your specific computer platform. This will allow you to easily extract, modify, and test .zip files (which all ROMs are). Running a simple file test before flashing a ROM, will tell you if the file has any errors or not, and will prevent you from asking the ever-annoying question, "Why won't this work on my device??". Bad downloads happen...I had one when testing the MIUI ROM I reviewed here...but if you test your files prior to flashing, you won't give yourself or anyone else as many headaches.
Secondly, if you like custom icons, and want to try tinkering with them a bit (but don't want to drop money on PhotoShop), I suggest downloading Gimp. It's super simple to use, and it's free, so it's a win-win. It can handle PSDs, and will give you the freedom to create things you like, versus always asking others to make icons for you.
Also, search the Play Store for a good root file explorer; Root Explorer is my personal favorite, but there are plenty of free alternatives available. One of the benefits of rooting is complete access to your device, and being rooted without having a root browser is like running a marathon with no legs.
Download Safestrap!! Hashcode has been kind enough to provide us with a safe and effective recovery, that allows for dual booting (meaning you can have two ROMs available to you at any time); I rooted my phone, left the original, stock-rooted system in tact, and then flashed my ROMs to the Safe System. Having the ability to leave your original firmware in tact, gives you a built-in safety net in case something goes wrong with your flashing. It's my experience that, if you follow the directions given by the devs, it's nearly impossible to truly brick your phone, and Safestrap gives you an extra layer of protection....so I recommend taking advantage of it. It may take an extra second or two to boot up, but the peace of mind it gives you is priceless in my opinion.
Lastly, I suggest staying away from ROM Manager; there's nothing wrong with the app, but most devs don't publish their Droid 3 work there, so it makes having the app a bit redundant. Also, while it's nice to have an automated system for downloading and flashing ROMs, you're cheating yourself out of knowledge in the end...learning how to flash things manually, and knowing how to navigate the recovery menu, can really save your bacon if you run into problems at any point. In my honest opinion, the dangers associated with rooting are and have been overstated...it's people who don't read, don't follow instructions, and rely solely on one-click solutions, that run into serious problems, and it's people like that who clutter up development threads with ridiculous questions and rants against devs. Knowledge is your friend, and if you can't take a couple hours out of your calendar year to learn about the root process, then you simply shouldn't root.
I've tried to provide links for (and will continue to add) all relevant information on the topic of rooting, so there's really no excuse for anyone who's new to the scene, to not have read them. I'm putting a ton of my personal time into creating this thread, and turning it into a repository for all things D3 root related, but I have no patience for people asking questions who's answers are easily found here, on the first page. Enjoy the thread, and hopefully everyone will come away a little bit smarter than they already were.

Launchers
*click launcher name for XDA thread link
Android launchers are a dime a dozen these days, and with so many choices, making the right decision can be daunting. Below, I will attempt to give an honest, objective review of each launcher, as well as its highlights and weak points. Hopefully, these write-ups can help you make a decision that's right for you. My only suggestion...test a launcher's free version for a week or two prior to spending money for Pro features. Don't buy something right off the bat, and then complain that it doesn't run well for you. Be smart and test them all first...and no (because I've seen this assumption made recently), these are NOT Gingerbread compatible, and will never be. These launchers are for 4.0.x only, so please don't ask why your 2.3.4 N1 is crashing every time you try to run Nova...
I'm not going to be rating launchers, only outlining notable features. Launcher selection is a personal preference for everyone, and I'm not interested in starting a pissing contest between people who think one launcher is better than the other. Take my reviews for what they are, and make your own decision...no need for hate.
Nova Launcher
review imminent...stay tuned
Apex Launcher
review imminent...stay tuned
Trebuchet

SELFKANG, I believe, is CM9.
EDIT: Love what your doing with this thread. Its fantastic, and I enjoyed reading what you have so far.
What are your screen brightness settings at for these tests? Auto would of course skew the results... I have noticed it seems like different roms have different stock brightness. I am a scientific person, but I am not super knowledgeable about Android, so excuse me if this is a stupid question!

Well deserved thanks to all your posts.

Not a stupid question at all. I was halfway through my first ROM test, before I thought of the auto brightness issue. I turn auto off, and set it at 50% brightness. I'll add that note to the OP...thank you for bringing it up.
And yes, CM9 is Selfkang; I was in a bit of a rush to get the thread up, and didn't label every ROM with the correct title. I'll get on it today, so there's no confusion moving forward.

Launcher Review???
Quick question guys... would you like me to add an ICS Launchers review to the first page? I'd cover the three major ones - Nova, Apex, and Trebuchet - but I have to warn everyone... I'm partial to Nova, since I've paid for Prime, and have been part of the private beta team for quite a while. I also have no intention of purchasing another launcher, so any additional features that Apex may include in a paid version, would not be reviewed. I think, at this point, that many of us have settled on a launcher already, but some people may find a review (other than those on the Play Store) helpful. Let me know what you think...thanks guys.

Love the thread. I would definitely appreciate a launcher review. I've been switching between Nova and Apex (Apex because they give free evaluation license to those who download the beta builds). I'm just looking for the stablest and quickest one

Really weird side note... in searching for app png files on Google Play, I noticed that you can now purchase a GSM Galaxy Nexus on there?! WTF is happening here?! It's really a sweet idea, but it's only available in the US at the moment...a market that's dominated by CDMA networks. Launching this option in Europe first sounds like it would have been a better business decision... just a thought.

Love the thread. Great time and effort has been put into this thread without a doubt. I left the links up for you to test my rom in the thread. I think.

Thanks for stopping bye man! I really appreciate any and all dev support I can get! I've got the Advanced Beta #1 downloaded and ready for testing, just as soon as I complete the Gummy tests.
My hope is (along with helping end users make a decision) that developers like yourself, can take a peak at where your ROMs are performing well or where they're performing poorly, and adjust things accordingly. I think that giving and receiving feedback from devs is vital...otherwise, you guys never know what people really like, and what issues people are running into.
I'm also attempting to take a little bit of work off your hands, by answering the more general questions here; questions like how to flash, which recovery to use, keyboard backlight issues, and whether a ROM is also made for GSM or not, are all things I can handle here, so devs can focus on more important things. Feel free to think of this as a User Forum (like the CM9 thread) for all users, and you can send people here for the more general information and troubleshooting.
Thanks again for stopping bye, and keep up the great work!

HTC Desire C - Speeding up and general optimisation

Hey there people!
Ok so the HTC Desire C seems to be a non supported device on here there are currently no ROMs for it and even the root/ulbl is not fully tested so devs with HTC experience get here to give this device what it needs!
Anyways the device runs on a 600Mhz processor running a long side 512MB RAM supporting Android 4.0.3 ICS, due to the specs the device can be a little sluggish under high operation situations so here are a few basic tips to help.
Install Zeam Launcher.
A small size launcher that is lightning fast, only thing that rivals it is the FTL launcher and looks like sense 4 launcher.
The launcher size is 338k (Google play size) very fast and minimal looking.
FTL follows the trend but size varies on ur device
Bit-Defender.
This is a tiny anti-malware suite, for full features needs payment, but for free it gives nice protection. and i use the desktop versions so yeah
if you prefer the finding ur device more so i suggest lookout due to free scream/locate and no it does not drain battery life!
Juice Defender.
I listen to music a lot when am out, my old X10 did well with an extended battery and Juice defender installed, so i say add it into the desire C, it actually saves battery and manages ur mobile data/wifi automatically.
(After root)
Install Titanium Backup.
This app is a god send, it can remove files embedded into the /system/app folder, so u can remove crappy HTC Sense launcher, also remove other bloatware and rubbish do be careful tho Rooting does void warrenty and removing apps can stop the device from working (WE NEED A RECOVERY!!)
Sysctl Config
I use this on my X10 for gaming, it provides a bit of a boost to performance not much but its there
(you must have busy box to run this, recommended to have latest superuser installed from Google play)
a scripting program - edit scripts (Advanced users/devs only)
This is what makes roms so dam fast over stock, devs have edited the files to increase VM Heaps and other stuff, if your a noob or no scripting skills dont attempt it wait for a pro to do it for you!
Try overclocking. (Advanced Users/Devs)
I dont know much about HTC kernels im a DoomKernel user for the X10, but he got the kernel another 200Mhz on a single core!
Idk if HTC have left any overclock on the kernel and i dont wanna damage my phone testing it as i got it 3 days ago, so feedback please!
Overclocking is one of the most obvious choices for speed, at the cost of battery life you can put the CPU past its standard levels, speeding up your device.
Personally i dont overclock past what doom set my kernel, if you wish to do it personally use NoFrills CPU (Free) or SetCPU (Paid) both need Root
Ok rant over! most of this stuff may not be yet possible on the device but i hope it does, its a nice little device cheap and cheerful! devs come and unlock the potential it has forget One X n S3 they got there stuff
Disclaimer
I Will Not Be Held Responsible For Any Damages In Any Area Or Spec Of Your Device(s) You Do It Your Fault No One Elses! Nor Mine Or The Devs.

Speed
Hi,
I'm a new user and I have a question. I just rooted my phone, and flashed up Nameless rom. But it works with 600mHz. Can I involve the speed?
Overclock or something?

Nope Nope Nope ^__^, basically its no good as the Kernal is stock and doesnt permit overclocking.

You should really rename this thread... it has nothing to do with optimizing or speeding up the OS. It just tells you about a bunch of software you could search for on the market, and then says, "oh ya, and overclock."

Performance problem??
Peep my signature..

Deactivating apps which are not really needed also increases the speed, because more resources are available.
I tried that in combination with the overclock kernel and that sped up my phone especially when using apps which needs much ram and cpu-performance.

And back we are
Lets get a few things updated shall we
_Ayhan_
Apex is a good launcher, bit bigger than Zeam but it works perfectly for me, no lag at all and supports themes!
szilike93 Nameless new ROMs have OC ability, with the correct kernels, as said in my 1st post, i would OC, i used OC on a different ROM and played games, didnt last long under bloon tower defense 5. ive just downloaded a new kernel pack from the dev of Nameless, selected a slight OC, but i shall be still setting max OC to 600Mhz but i will be changing the Governor to InteractiveX and I/O to deadline (Going on what worked best for DoomKernel)
Gamephantom
Yeah removing sense UI would be better off for the phone, but as far even the new "De-Sense" options still have baseline sense installed, until Cyanogenmod works fully we have to stick with it, although the devs have made the device smoother with sense, Cyanogenmod should take the crown
So any updates from me?
Well OC kernels are out and working can try them if you wish, New roms are around which are fast, no new "Super" apps to speak of, just a shame its only a single core 600Mhz, there are some apps im testing and shall report back, such as the Jellybean drivers, see if that wacks my battery using GPU rendering, hopefully not, all testing on Nameless 7.2 with 722Mhz Kernel but will be UC to 600Mhz. Hopefully battery life dont suck, Slimsense still best battery life personally for me
Later Guys!

You want to get a good battery life, just push a stock systemui that don't have battery percentage numbers. Images in stock only have 4-5 batt images, while in percentage it gives accurate %1 reading 100 batt images.

You should do as Xdroidie626 sais.
Download Nameles's ROM and enclosed within You will find 3 kernels. Choose from 2 that allow You to OC Your CPU and flash it.
I'm using the 806MHz Kernel and apart from the obvious,battery life dicreased,can't complain about it at all.
HTC should have released Desire C 806MHz capable in the first place.
Lucky noobs we are to have XDA website and Devs themselves to provide us with tools of salvation from "stock" misery

[GUIDE] bcvictory's War On Lag

Hey XDA-ers!
BCVictory here! (Call me Bailey, my real name, if you want)
Ever since our beloved Nexus 7 came out there has been claims of people having problems with lag.
Especially since 4.2, the claim has gotten even more traction and it's more of an issue.
I'm here with some things you can do that may help fix/stop the lag.
But first, what is lag?
Lag is: Fall behind in movement, progress, or development; not keep pace with another or others.
So in Android the definition of that could mean: Falling behind in frame rate, not keeping up with or detecting your finger and not 'buttery' or 'smooth' (microstutters)
So now we know what lag is here is a few ways that people claim it stops/reduces the lag.
THIS ALL COULD BE PLACEBO!
ANDROID SETTINGS
Go into Settings
Under the System heading, go into 'About Tablet'
Tap 7 times on the Build Number
You should see Developer Options appear
In Developer Options
Turn these options on:
Disable HW Overlays
Force GPU Rendering
And change these options to either off or 0.5x
Window Animation Scale
Transition Animation Scale
Animator Duration Scale
APPS
Seeder
https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en
This app claims to:
Assist the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.
On some devices, applications load significantly faster (particularly large ones like Facebook, Chrome, and Youtube), and task switching becomes effortless. Fewer visual "hiccups" occur.
Alot of the media and devs have said this app does not work but it does make this note:
This app does not increase raw performance, but rather eliminates some types of annoying lag (ie. applications briefly freezing, jerky scrolling, delays returning to the home screen, etc).
LagFix
https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix
LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily.
Forever Gone
This app will fill your SD Card with many blank files(*.blank), then delete all of the *.blank files.
One of the main 'fixes' people say to fix the N7 lag is to delete some files to make sure the storage has at least 2GB's free.
This app has helped fix lag that relates to this problem without having to delete those files.
Greenify
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
Greenify help you identify and put the bad behaving apps into hibernation when you are not using them, stop them from lagging and battery leeching, in an unique way!
This app helps reduce the amount of rouge apps in the background and save RAM. It's not like a normal Task Manager, It does it automatically.
Pimp My Rom
https://play.google.com/store/apps/details?id=com.androguide.pimpmyrom
http://forum.xda-developers.com/showthread.php?t=1908269
Pimp My Rom is an app that will allow you to choose between a plethora of tweaks, mods, hacks, features and apps to modify and improve your current rom. Pimp My Rom gives you alot of options to enable speed and battery saving tweaks therefore theoretically reducing lag.
FLASHABLE MODS / INIT.D SCRIPTS
Crossbreeder
http://forum.xda-developers.com/showthread.php?t=2113150
This is a new take at Android lag reduction. It's lightweight and won't consume battery. Users have reported drastic improvements in usability and even benchmark scores. It will show noticeable improvements on all Android devices from Donut to Froyo to Gingerbread to Honeycomb to ICS and Jellybean.
This is a combination of 5 different methodologies to reduce Android lag.
1. Removal of DNS lag
2. Change wakeup threshold kernel parameters so read blocks are released instantly and writes never wake up as we have an external entropy generator.
3. Modulate OS entropy levels for lag reduction. (Just like Seeder)
4. Remove /dev/random as it's blocking
5. Frandom support
Mitsuyoshi EXT4 Mod
http://forum.xda-developers.com/showthread.php?t=2280496
This removes the journal from all EXT4 partitions. This gives (on average) a 25% increase in system speed (due to the increased I/O rate)
V6 Supercharger
http://forum.xda-developers.com/showthread.php?t=991276
This claims to: Makes your phone/tablet FAST... super snappy with better multitasking! It rearranges and fixes the OOM Groupings and Priorites and lowmemorykiller values. So basically, it's a COMPLETE MEMORY MANAGEMENT FIX! NO LAUNCHER REDRAWS, faster than ever, multitasking is better... why? Because it works with the lowmemorykiller and letting it work the way it's meant to work.
Jay's Recipe for Buttery Goodness
http://forum.xda-developers.com/showthread.php?t=1946347
The script remounts /data and /cache with discard and noauto_da_alloc, disables fsync, enables a 128mb zRAM and set-ups a good, stable starting point for further modification. The result is a stable, considerably smoother multitasking powerhouse with overall better power management and performance.
INSTALL/CHANGE KERNEL - OVERCLOCKING
If you are running stock kernel or another kernel, it might be a good idea to try a new one.
One of these benefits is to overclock the CPU and/or GPU.
For my guide to the 'best' kernels for the Nexus 7 click here: N7 'Best' Kernel? (Performance & Battery Tests)
CHANGE LAUNCHER
If your launcher is the only thing that is lagging you might want to change it. There is a guide to the smoothest launchers at this link: http://forum.xda-developers.com/showthread.php?t=1899350
CHANGE ROM
If none of these tweaks aren't working or aren't enough for you, one of the last options is to change your ROM. There are lots of options out there so have a look around the Android Development and Original Development sections.
My personal favourites are Paranoid Android, P.A.C- Man, RasbeanJelly & SaberMod.
DOWNGRADE TO 4.1.x
If all of the above is not working try some of the older roms that use 4.1.x as their base.
WIPE EVERYTHING AND START FRESH
If absolutely nothing above works then it might be best to wipe everything and install a clean rom.
If any of these steps worked or didn't work for you, please vote in the poll above and also post below what did so you can help others.
If you find anything that helps or doesn't help reduce lag, please post it below.
If you found this helpful, give this post a thanks and give the people who made these tweaks a thanks too.

[Kernel] Vindicator [AOE3] [Strict-Aliasing/UberTC/Loop-Nest] [-R3-]

Vindicator Kernel
Intro:
This is the first Samsung kernel I've ever developed. I just started developing on android a few months ago so I'm brand new to this. I don't really consider myself a developer, I'm just good at figuring things out, all credit goes to the real hard workers coming up with original ideas like Franco, Imoseyon, Ktoonsez, etc. I hope you like it and I won't be offended if you hate it. All ideas are welcome and I'll try to help as best I can. If you wish to use this kernel in a rom , feel free! Although I would love it if you let me know just for my own curiosity.​
Goal:​Keep kernel as lean as possible while adding certain, desirable features, upstreaming source, and optimizing for maximum performance and battery life. The default settings should be optimal for a balance of battery and performance without a need to tweak.​

-Scheduler considers cost of balancing and doesn't overestimate average anymore
-Small micro optimizations
-Improve Low Memory Killer routines patch from neobuddy89
-Add rbtree optimizations to LMK. (Significantly improves LMK performance)

FAQ's
1. What Is VControl And How Do I Use It?:
VControl is a kernel tweaking "app" built into the ramdisk. It is accessed via terminal emulator. To use it simply download terminal emulator, Type "su" without quotes and hit enter. Grant terminal emulator super user permission and then type "VControl" without quotes. Please note that it is case sensitive. This will bring up a text menu and you navigate by simply entering the option number you want and hitting enter. It is currently a WIP. FSync control and Power Efficient Workqueues don't currently set on boot properly More will be added to VControl over time.
2. You Broke My Phone! Fix It!:
It will be quite hard for me to figure out what is going on if you don't provide details and a log of what happened. To get a log use any file manager with root support and navigate to proc/last_kmsg.
3. What Kernel Tweaking App Should I Use?:
To Tweak the kernel, currently the only app that works well is KTweaker. To get KTweaker simply flash ktoonsez kernel which will install the app, then flash this. You will have the app unless you wipe data. You can also use VControl for a limited number of things
4. What Do Power Efficient Workqueues Do?:
Typically when a task is created, it is bound to the cpu it was created on. This is great for performance due to maintaining cache locality. However its not the best for battery life. Power efficient workqueues attempts to schedule tasks on already awake cpus. A quick note about awake and sleeping cpus. A sleeping cpu doesnt mean the cpu is turned off or not hotplugged, nor does this mean it has to be deep sleeping. A core can be online and still be sleeping which means it uses very little power. This is why we are able to run with all 8 cores on all the time. Most of the time the majority of the cpus are sleeping. With power efficient workqueues, jobs will attempt to schedule on awake cpus which means we dont have to wake up the cpus that are sleeping already. This means we lose cache locality so we suffer a small (very small) performance hit but we potentially save noticeable amounts of battery. Enable for battery, disable if you plan on benchmarking or just want the extra power. They are off by default.
5. What Is Strict Aliasing And Why Should I Care?:
One of the big things Linaro does with improving Android's performance is fixing violations of what's known as "the strict aliasing rule." A pointer is said to alias another pointer when they both refer to the same location of memory. This is OK and not an uncommon thing to do. The strict aliasing rule is that pointers of different types should never refer to the same location of memory (aka alias each other). Strict aliasing allows a compiler to make some assumptions when compiling and optimizing code that it otherwise couldn't. It's actually one of the biggest optimizations you can do and it is fairly hard to add which is why most people don't. Here's a nice read up on it http://cellperformance.beyond3d.com/articles/2006/06/understanding-strict-aliasing.html#benefits
6. What Does Moto QuickWakeup Do?:
QuickWakeup is a driver developed by motorola which increases battery life when the screen is off. It allows for only the modules which need to be woken up during sleep to wake up, thus conserving power.
7. What does Small CPU Task Packing Mean?:
Task packing Is a process done by the scheduler. What it tries to do is pack all tasks onto as few cores as possible. In this case, it only packs tasks for the low power(small) cores as we want to maintain maximum performance and spread the load out on the bigger cores. The advantage of packing tasks is that if we envision a scenario where there is a 40% load and that FETs spread out across the 4 small CPUs at 10% load each all 4 small CPUs are awake and running at a low frequency. With task packing all 40% would be shoved onto 1 core and the other 3 would sleep. This provides energy savings. However there becomes a point where the frequency required to process the extra tasks becomes high enough that it would use less power to run two cores at half the speed rather than 1 core at a very high speed. In this scenario the scheduler will automatically let tasks spill over onto adjacent CPUs in order to maximize power efficiency. One down side to this is a small performance hit due to having to pull the other cores out of a sleep state in the event of needing immediate power. However I would guess most people couldn't notice a difference.
More will be added as they come up and I think of them.

Please note that this is only tested on the smg920T model. I have no idea if it will work on others

Works well thank you!

Happy to hear that sir! You are the only other person to have tried it so far so that's good news. BTW. Idk what AVS# you are but I'm an 11 and I have stably undervolted by 75 for the A53 cores and 50 for the A57s. Maybe that will help someone.

I like your ideology behind this kernel. Totally reminds me of imosyen nice to see another dev here! I tend to keep my volts as is. I always have problems
Would also like to say that this kernel is best one for my phone so far! Haven't noticed anything but stability. Thanks

Haha. My first kernel I ever made was for nexus 6 based on his lean kernel so that's what I learned on. In fact I believe I've got almost all the stuff removed that he has removed back on nexus 6 plus even more that I've found. I'm a firm believer that less is very often more. Expect more trimming down in the following builds.

Well now I know I'll be in good hands ?
I've been following him since the note 3 days.
Can't wait to see where you take this project!

Downloading and testing now. Not really related, but I was wondering if power save overrides cpu clock/gov/anything else? The reason I ask, is that I typically underclock or undervolt a bit to save some battery but keep in normal high performance state with PS off. But if PS mode does this anyway, I shouldn't bother should I?
Wow, that 3rd post (FAQs) was super-informative!

Edit: Everything seems to be running perfectly fine so far. Charging up so I can see how the battery life is. I'm currently on OZOP's ROM.

To be honest I dont know specifically what power save mode does. I've only had the phone for like 6 days. Ik ps limits frame rate and stuff like that so You will save additional power beyond Running in normal mode, but I'm not sure how it affects cores and frequencies currently. This phone is a whole different beast than my nexus 6...I would like to add more, lower frequency steps to save more power. Glad to hear you are liking it so far though! And I plan on adding a configuration guide of sorts in my 4th post with more detail on the controls available . I also plan on getting synapse working properly as that will enable significantly easier kernel tweaking.

Thank you! Your build script and zip file were a massive help to me. This is completely different from building for a nexus. And I'm not too worried yet the device is little over a month old. I'm hopeful we will see more development start to come. I tried to use your new script setup but I couldn't get it booting for some reason. I'll have to revisit it. I'm sure I didn't something wrong. I'm a Noob.

Lol once I wrap my head around all these different variants I'll try and get a build working for the edge. Took me days just to get call audio working

I know there's a unified method that ktoonz and a few others use/developed, reach out to him for assistance! However, just out of curiosity I flashed this baby on top of sac and ram deodexed rom for the s6 edge sprint variation and it works lol....only issue ive noticed so far is the "storage message" keeps popping up.

O_O that's suprising...ik there's some differences...hmm...well then. And I am going to try and get their method working soon. I tried to get it working earlier and got it compiling correctly but couldn't get it to boot sadly I will revisit it.

Going to give your kernel a run today and see how it goes! Always love to see more options around here.
I'm curious about the memory leak(s) you say you've patched. I wasn't really aware of any on the kernel side, can you give a bit of explanation here?
