LMK of any issues. Thanks.
BTW here are the Overclocked Components of the kernel
CPU = 1500mhz (default = 1000mhz)
System/Avp/vde BUS= 266400 (default = 240000)
GPU = 400mhz (default = 300)
BTW, if you like my work, pls buy me a BEER

Clemsyn, thanks for your efforts. any chance of getting your Kernel for Adam CM7?

Well...
...what can I say. It´s freakin' fast! Very quick touch respons. 1500MHz does not seem to be a problem. I was not able to find the specific gorvenor you mention.
Only issue I´ve run into is the auto-rotate. When it rotate to portrait it won´t rotate back to landscape mode. Changing cpu freq. did not help. Actually it seems the sensor does not work, as it only rotate if an app forces it to change mode.
As for beer - alcohol is no good mate! Sorry.

I got a Quadrant score saying 3273, a number My adam has never reach before.
Everything is fast and has a quick and stable responsiveness and surfing the internet is a bless. I would love the HC to have these qualities, maybe you could join the team? Maybe you already are on the team
The 1.5GHz overclock is doing a nice job and there has been no issues.
Still an issue, the sensor to rotate screen.

Am I talking to myself?...
So PimpMyGtab is here: http://forum.xda-developers.com/showthread.php?t=895825
And with Data2Loop on the Quadrant score is 4384...!!

Meekos, chould you check video, especially 720p or even 1080p that didn't work well with standard kernel?
Thanks in advance.

Meekos,
I am currently trying to OC Adam's kernel but with no device at the moment, it's kinda difficult (but could be done). I built a new kernel (which will break wifi but needed to fix the accelorometer, I think). Here is the link, LMK how it goes

You are absolutely right. I just don´t want you to become less brainy because of alcohol that I have sponsored. A bio organic smoothie maybe?

great ROM!
Thank you so much for that rom.
It makes my Adam just the best tablet out there.
The speed is phenomenal...
OC 1500 UC 1150. Under 1150 it is too unstable.
But again what a speed!!
Battery is affected but well i haad like 4-5 hours with a full charge and left it at about 12 %...
WIFI Ok 3G Ok all ok!!
you are a star!!!
i own you a Smoothie then
Best

oooppp GPS not working

Rediscovering SuperPower v 0.80 BETA

So I was over in the Atrix forums the other night because there was someone over there who was wanting some help deciding if they should ditch their Atrix for the Thrill 4G. The overwhelming amount of posts about some of the hitches with the Thrill were in regards to the battery consumption and the RAM getting hammered with general usage.
Over here since a bunch of us are actively doing doing what we can to try and speed the development along having being trying new things and tweaking this or that in an attempt to make some progress toward real development.
Here is a link to what I said over there:
http://forum.xda-developers.com/showthread.php?p=17448824#post17448824
So I was running back through all the apps. and such that I had used in the past on other phones and hidden in my lengthy list of apps. used to get every ounce of power out of whatever phone I was jacking with, was SuperPower. I had the paid version but it has subsequently been ditched and redone it seems and now takes the form of a BETA.
This BETA I dropped onto my Thrill and started to go through the options that are available on this version that were not there before. You can now manually go into SuperPower and tell the app. what program you want it to kill when the screen goes black, how you want wi-fi and/or radios to behave, etc. It is extremely customizable.
Until there is a custom ROM and all that for the Thrill I think we are going to have to do our best to manage the few minute undesirables this device has with things like SuperPower. So, my end result as it stands right now on battery and RAM usage, I am using a few different apps. and I will list the links below for your convenience; is after about 10 1/2 hours of fairly mid to heavy use I was sitting at about 71 % battery life. Understand I let the battery go down below 20 % then charged it back up to 100 % with no interruptions in the charging process. You should do this at least once a month just maintain good battery health and longevity anyway. Especially on powerhouse phones like the Thrill 4G.
Now when I say mid to heavy usage this is my interpretation of that; regular talk time throughout the day, 100+ text during the day, market and music downloads, 2D and 3D gaming. When it was time to charge again I was at 13 or so hours with 49 % battery still showing. Not to bad as it was blowing through battery like it was free before.
Here are the apps. I used with download links. If you have questions or anything let me know or PM me:
SuperPower BETA v 0.80(*Must be rooted by the way to use this*)
https://market.android.com/search?q=SuperPower
Chainsfire 3D(*must be rooted*)
https://market.android.com/search?q=Chainsfire&so=1&c=apps
*As a side note besides the other great benefits this app. offers what I use to help with battery usage is the Night Mode feature*
SPB Shell 3D (*This is a paid app. and worth every penny IMO. But if you are not down with dropping the change for it use LauncherPro or one of the other free Launchers out there*)
https://market.android.com/search?q=spb+shell+3d+&so=1&c=apps
Advanced Task Manager
https://market.android.com/details?id=com.arron.taskManagerFree&feature=search_result
Hotspot Guru
https://market.android.com/search?q=Hotspot+Guru&so=1&c=apps
Besides what I listed as benefits for SuperPower there are a ton more that I have not even touched on. This app is jam-packed full of modding goodness. get the app. and use at your own risk kind of thing and explore this bad boy because its a doozy. Lol! Hope this helps.

What are you doing specifically on the Superpower app to get such good battery life?

I think I am at the point that the best option....is to just return the thrill.
I tried using it as my dedicated device for a few days now and it just isnt working out. it freezes,locks up, bluetooth is not holding a connection ,just all around does not perform like I expected.
I really want to like it haha....i really like the overall physical feel of the phone. The 3d is great (after waiting a ridiculously long time for it to load) but it is just too sluggish and quirky for me to enjoy daily.
I am most likely going to start from scratch tonight and give it one more week....but without some major magical miracle (like fully working cwm, kernel development and the ability to flash O3D roms) i just dont see myself keeping the thrill.

Really. Mine flies through screen's and apps with Zero Lag including 3D. As far as it sounds to me, sounds like your phone is either defective or loaded with a Ton of apps running in the background constantly. If it's apps running in the background all the time as far as I recall Froyo didn't do the greatest at managing what to shut down and when. Either way goodluck.

Thanks! As for apps...that isn't the issue for sure. There are a number of things the phone does quickly but there are a few it does not. The camera does concern me. When I open the three d can it just goes blank screen for a while and then finally comes up.
Hell even typing at times everything will occassionally just pause for a few.
I haven't given up yet. I am going to hard reset and give her one more go

Try using taskiller and set it up to kill apps when the screen is off. That seems to work well for me with app management.

Personally, I have been using "Autokiller Memory Optimizer," which is NOT a task killer, but allows you to set memory limits.
This may be overly aggressive, but this is the setup I have been using, and it has been treating me very well. From top to bottom, in MB (from "foreground app" to "empty app"): 18 / 24 / 32 /100 / 125 / 150
I may tweak it down a little, but in general this setup has allowed me to multitask between apps really quickly, while Android "kills" the apps I'm no longer using. Highly recommended for (rooted) Thrill users!
While I'm at it, another useful (paid, requires root) tool for the thrill is "Autostarts."

With what I have done so far with SuperPower and such my phone is flying right along and running consistently with between 186 and 202 mb of available memory. So with the processor and RAM hauling ass I am loving this phone. I am can't wait for some some stuff to come down the pipe for this phone. There is definitely a lot of BS stuff running hidden that can slow it down but with SuperPower and the task killer and all the stuff I talked about when I started the thread I am so far satisfied.

Running mine basically how it came straight out of the box, no custom rom, only fancy apps I'm using are appkiller and setcpu right now. Battery life before I got setcpu was... less than desired. But when I got it and configured it to only use as much processor speed as I'd need for my "on the go" usage, I get enough life out of it to last me the whole day, and get home at 20% battery. What I did? Set it so it uses minimal CPU speed (30%)with the screen off, and in calls, and during normal usage it only runs at 60% and that's more than enough to handle my regular usage of texting, emails, calls, browsing, a little bit of gaming, near constant syncing, as well as a good amout of music streaming and maybe only about 50% standby time. Love this phone, dual core with half gig of ram is pretty much complete overkill as far as any phone goes. I fly through Apps only using 60% of the cpu's stock capabilities.now for the times when I'm out longer than normal (over 14 hours a day) I have it set to use minimal CPU speed at 15% battery life and less, in case of emergencies.

I'm returning mine. I either put too many apps, get too many defective phones, or just need a phone with more memory. Never had running out of application room on the Captivate or Inspire.
Camera can take up to 8-10 seconds to finally come on. This is a pain when I want some quick shots of the kids at the moment.
Mine also freezes up while I'm using the keyboard whether it's the stock or swiftkey or better keyboard. This is the 2nd thrill I've had and same issues. So that leaves pretty much the GS2 that's coming out. And Samsung scares me.

Until we get a custom kernel.....i am not aware of anything that will allow us too throttle cpu speed. what are you using? sure the apps will allow you to make setting adjustments yes....but those settings are not sticking (not on the apps I have tried)

I'm using the xda app setCPU it's a free download for site members and only requires rooting your phone. Note that the app only controls the max and min speeds of the processor, this isn't overclocking. I don't really know that much about the app beyond what it's supposed to, and seemingly succeeding at doing. Everything that I've done with the app seems to be working fine. I tested it with min and max at only 30% CPU speed (the lowest it seems to allow for), and I definitely felt it in the way my phone responded, the entire time (atleast ten mins) up til I turned the settings back up

SuperPower can throttle it up a bit. It is one of the settings to be checked off.
Open up SuperPower>scroll down to: CPU Scaling: Enable and check the box
Below that is a box you can check for CPU Scaling: ondemand
Like I said in my original post there are a fair amount of options that gives us the opportunity to have our devices running at their best. I appreciate everyone's postings about what they are trying and so forth. This is how it all begins to getting stuff done. Thanks guys.

Not a problem my good friend, I'm a huge fan of this device and the potentials it possess, I am glad to be a part of any improvements that can be made.

Can you post your setcpu settings?

I'm running my CPU at 600000mHz max and 300000mHz min for normal use, and babe a profile that sets it to 300000mHz max and min with the screen off. Have all my profiles set for "on demand" so it only ramps up the CPU when it needs it

[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.

In order to use "advanced mathematics" and "complex formulas".. You might want to provide a format for "the results" you want people to provide.. Without a stream of formatted data to input your "complex formulas" and "advanced mathematics" is impossible..

"Advanced mathematics" and "complex formulas" sounds like you are doing an infomercial.

My Galaxy Nexus is proof of undervolting being unstable using software while being stable with manually programming the voltages. So I am going to give this a good shot anyway.
My Galaxy Nexus uses SmartReflex to undervolt.
Look at this table I made:
https://docs.google.com/spreadsheet/ccc?key=0AuqacKmGLKJ6dEdJZG5QTmNtQnoyYk0zbm5IanluMHc#gid=1
You see the core or gpu was already crashing at 974mV, which was the reason why I stopped undervolting using the thread. But don't give up, I tried again using SmartReflex because I felt I should be able to get lower. And now I am at 911mV but I did not try to get lower yet.
I plan on undervolting by actually programming it. I don't know how you guys undervolt for the Nexus 7, since I am fairly new with this device.

Using that I can calculate which voltage to take that will work for 90% of us or 99% of us or maybe 100% ?
For that I need some results. The more the better.

The only voltage settings that will work for 100% of people are stock voltages.
you will run into endless problems if you release an undervolted kernel because what works for 75% of people won't work for the rest.
If you adjust voltages to include more people the people that can handle the lower voltages aren't getting the full savings their device can handle. Which defeats the point of releasing an undervolted kernel to save battery.
Undervolting should be up to the individual, just release with stock voltages and make a guide showing people how to undervolt.

^^ Truth
I've done a bit of pc overclocking over the years and we'd always seek out the best steppings to find cpu batches that would give a better clock speed for less volts. What would work on one person's cpu wouldn't work on another sometimes even within the same stepping. (My current machine is getting long in the tooth but it's running a 33% OC below stock volts and stable as a rock.)
When the N7 cpu's are tested the stock voltage is the point where 100% of them will run without issue. Certainly there are many, maybe even most N7's that will run undervolted but until you try it you just won't know. Undervolting needs to be done on a case by case basis.

I uv by 100mv on every step on Franco kernel and I've never had a sod or reboot. Maybe you could release different versions like light, medium and heavy to cater to different users that have sets than can uv more or less. To address all these people naysaying I say just go for it, don't let these people dishearten you from what you want to do. I'm sure there will always be users who are willing to try

sorry to break the fun lol
Opened a thread with undervolting settings in different situation. For now i think its the lowest possible

That's exactly the same as what I have done. 100mV right across the board, and I have also never had a reboot or any other negative effect from doing it. Just a bit more battery life.

I too UV 100mv across the board. Never had an issue. And I OC up to 1.6ghz.

Same here, no issues with 100mv UV on stock speeds. What would happen if we went too low, would it fail to boot at all or is there some safety mechanism that would allow us to boot into boot loader?

When either OCing or UVing, you should ALWAYS test out the changes prior to saving them as a persistent boot state. This way, if you set something too high/low and it proves to be unstable, if you restart the device it will revert back to normal.
In the event that you OC/UV too much, yes, you would see signs of instability. In some cases it could show up as soon as you applied to change, in other cases it could take a while to notice. For example, some games or other high processing powered activities could FC/crash. Or your tablet might freeze or reboot. But again, as long as you didn't save your changes as a boot setting, it will be fine once it reboots.
In the event that you did save it, and the settings were unstable for your device, you could boot up into recovery and then manually erase them from taking effect. Recovery doesn't use those settings, as it's technically a different OS. But that can be complicated a process for some. So test test test save. Or don't save and just apply them manually.
Two other points:
Yes, most (all?) devices do have safeguards to protect itself against permanent hardware damage from OC/UVing. If it gets too hot, they will often shut down to protect themselves.
And just because one device can handle being OC'd or UV'd to a certain level doesn't mean they all can. Very minor differences in each component can impact one devices ability from another. The manufacturers only test to see if they can handle the published speeds/etc., but in many cases they can go higher if set to. In others, not so much.

Thanks for that phonic. Given the range of ROMs and kernel's available and the improvements already built in, under volting may not help a lot but every bit helps. Eg this screen on time is pretty good.Close to six hours screen on time with iirc 35% battery remaining.
Paranoid android with motley kernel. I don't over clock the nexus 7 as its fast enough. In fact I under clocked it to 1000 MHz max before and it was still fast but the screenshots are at stock volts and speeds.

it's actually plain simple. If everyone posts results. I can make a kernel with voltages that work for 75% of all people or maybe for 95% of all Nexus 7 owners.
It's called mathematics. But to do that I need as much results as possible.
Easy to do if you know what you are doing, right ?

Good workaround (Kernel/Firmware) against overheating?

Hello guys I got some huge problems here.
I recently switched from my Z2 to the Z3+ and actually like the phone but the overheating is insane and especially kills Pokemon Go through CPU throttling, which runs smoothly on my old Z2 .
So far I am on 253, cleaned it up and tried a self modified and the zach beta9 Kernel and and runs quite bad on both. Is heating a lesser issue of 224? I actually do not want to reflash the whole system to 224 just to find out it doesn't get better.
Also is there a way to undervolt/underclock? I can change settings in Kernel Aduitor but I have the feeling the phone doesn't really care.
Help much appreciated - thanks!

Try Zach beta 8 kernel. Limit max cpu frequency by kernel auditor.
Still it's only your Goodluck if your device cools down. It's a bitter truth about this model.

Do you have a clue whether 224 or 256 make a difference?
I will try beta8 and report back.

no there was no thermal improvements between these builds, dont flash your system back
but do underclock and tell us the results!
Im also affected by your exact problem

Try this kernel, seems promising. I haven't tried it since it doesnt have twrp.
http://forum.xda-developers.com/xpe...m5z-kernel-t3421630/post67813517#post67813517
Edit: Today I have flashed 256, haven't found any improvement. As per my experience 256 haven't brought any noticable change.

**** posted twice and dont know how to delete

Thank you for the replies!
Tested zach beta8, didn't help. Now I am testing http://forum.xda-developers.com/xperia-z4/orig-development/kernel-om5z-kernel-t3421630/ as suggested and if that doesn't help much also with http://forum.xda-developers.com/xperia-z4/general/kill-overheating-flash-zip-t3421782.
And Stamina Mode helps at least a bit.

Statusreport: It always runs bad. But best at the moment with root patched Stock Kernel (253) and that underclocking zip. Although I think that underclocking doesn't really help at all.

What are your temps? When does it start to throttle? Done any thermal-conf configuration to allow more heat?
---------- Post added at 21:03 ---------- Previous post was at 20:58 ----------
I know that @Trilliard has a very good and stable cpu governor where he has disabled two of the little and two of the big cores, this helps a lot if you underclock the remaining 4
Here are his files:
http://forum.xda-developers.com/xperia-z4/general/dont-custom-kernels-want-to-avoid-idle-t3409647
UPDATE: Added my edited files used to apply CPU tweaks (cores down clocked to 0.9 and 1.2ghz, two core disabled, tweaked cpu governor, power and others mods) and these files located in etc folder. Replace them and set correct permissions then reboot.

Actually I didn't know about this combination - I will try it thanks!
Do you know about a thermal-conf? Actually never tried one. The phone gets hot indeed but I still think there might be some space before it actually melts.

Thats what i thought as well i have my own here, its based on another persos post, but i dont remember where...
Anyways, his camera mod worked, but cpu throttle was not tampered with, and it caused a very unbalanced throttling... Ok yay i can use the camera linger and fluently, but when i exit the camera app, i cant use the phone couse its runnig at 348 mhz...
So i i did some modifications to it cpu never get under 840 for little cores, so your phones menues end web browsing are always safe from performance drops.
I made it to be able to play Pokemon go, and achieved a lot better resault than without any changes.. still prefer playing on my shield tablet, but if i dont have it around when theres a lot od pokestops nearby, then this will work for me.
While playing Pokemon go it does not go over 80 degrees, but using snapshat it can get to 85, so dont use snap for to long
Let me know if it worked for you!

Oh nice! Thank you a lot! I will totally try it out directly when PTC comes back alive. X)
What kernel and governors do you use?

Im using stock kernel, may switch to another soon. Im using stock bcause of batterylife and idle power consumption
Im using the governor and cpu modifications in this post ; http://forum.xda-developers.com/xperia-z4/general/dont-custom-kernels-want-to-avoid-idle-t3409647

Hmm. Still runs ****ty.
Can anyone give me a short guide how to edit thermal and governors?
According to my observations the phone gets hot and then cold. I think the throttle is more aggressive and needed and I want to make it less aggressive.

Update:
I made my own modifications to the thermal engine. It is pretty bad for battery I guess but I had a very good expierence playing Pokemon Go with it today. Yes the phone gets hot. Like it doesn't drop below 70°C while playing and regulary hits 80°C but it works good. No dark screen, no 0 CPUs downclocking. So far it's fine for me, maybe I get squeeze even more out of it.

Done any other modifications to your file for a while? Or is it working good for you now? What's your SoT?

Still working good for me. Not sure if I can really squeeze out more and as long as it works at the moment I do not have a good motivation to try anything else.
No idea about SoT. Always running around with a powerbank. Probably bad, it is not designed for good battery life.
