What kernel is best for battery life and supports Kcal except Hells core?

Zen and Franco kernels are excellent choices. In using Zen currently.
It's all just an illusion

The things that gave my N6 better battery life.
1. Flashing Franco' s kernel (default settings).
2. Black wallpaper (app No Wallpaper).
3. Change wifi-interval to 200 (build.prop editor).
4. Flashed black google now launcher (XDA thread)
5. Disabled services ( XDA Guide to disable Google play services; app 3C Toolbox).
6. Installed app Pixel Battery Saver.
7. Installed app Greenify.
8. Disabled not used apps.
9. Clean Manager to block most apps to auto start.
10. K-9 mail instead of Gmail.
11. Dropbox of the blackout team.
NOTES
Pixel battery saver switches of pixels, there are a lot of options. Needs trial/error. Than it is possible that ticking on button/link won't work.
But there is an option to turn off the app.
The black google now launcher does not work when the original gnl is updated to a recent version.
We could ask OP for an update.

Turn on airplane mode

Might as well turn it off then
BTW: a weak/bad connection can be a battery drain too if you have a weak signal, the modem then keeps searching indefinately for a good connection.

[NAND] N00bDroid (1.1) (Based on CRII CM7.2) [28 OCT 2012]

After following the progress made here, I decided to make my own modded ROM.
The name was chosen because I'm a total newbie in modding and I don't expect it to be very good, but well enough at least for me.
I DON'T TAKE ANY RESPONSABILITY FOR ANY PROBLEM WITH YOUR DEVICE(S)!
ABOUT:
- Based on CoolrunnerII's CM7.2
- LauncherPro (Because Nemus started to lag)
- Increased Heap Memory size to stop Market and Wallpaper problem (now the Market can be updated)
- Replaced Music with Winamp (Beta, but stable version of Winamp to be as light as possible)
- I "borrowed" Kuskro's ideas (like quicksettings and RealCalc)
- I included Rotation Locker (to change from portrait to landscape)
- I included some lines in build.prop which improve 3G and changing to wi-fi and wi-fi connecting speed
- I gave up on CPUTuner because it caused too much lag for the small ammount of saved battery
- Bootanimation changed.. Thanks to SDogo for the X1 Bootanimation.zip
N00bDroid 1.1 Download
N00bDroid (first release) Download
HOW TO:
- Format in CWM Recovery partitions /system, /data, /cache
- Install ROM - Detailed instructions HERE
- Boot into ROM
- Once booted, make sure it won't go in standby until after next step
- Go in Settings>CyanogenMod settings>Display and deactivate everything except 0 degrees
- Go in Settings>CyanogenMod settings>Performance and check Use 16bit Transparency
- Go in Settings>CyanogenMod settings>Performance>CPU Settings>Max CPU Frequency and set any freq between 528 and 576 MHz
- Reboot in recovery
- Install the GAPPS
- Reboot
- Have fun
I will put here a list of tweaks when I will have more time
Thanks: Sp3dev, Zargloub, CoolRunnerII, Jerrytan93, Kuskro, Elibl and BrianXP7 for contributing at this project
Working:
Mainly:
-Mobile data (Voice/3G Edge/HSDPA) - Improved HSDPA to wi-fi change speed
-Wi-fi (currently it works only with WPA)
-Bluetooth (as CoolrunnerII says, if you deactivate bluetooth, the battery will drain very fast, so after using bluetooth, deactivate then reboot)
-GPS (I haven't test yet, but it should work)
-Camera - Without Auto-focus
Secondary
-Flash LED
-Coloured LEDs
-Battery life about 18 hours (with 30-40 minutes music - that took a bit - , 10-20 minutes wi-fi, 5-10 minutes voice call and some messages)
-Market can be updated
____________________________________________________________________________________________________________________
Not working/problems
- battery still drains too fast (in standby it's about 25 times more power consuming by coolrunnerII's measurements)
- Wi-fi WEP is not working
- Battery meter goes to <20% after reboot. However, it will not influence overall battery life
- Camera is not focusing
- FM Radio
- HQ videos
- Front camera
___________________________________________________________________________________________________________________
TWEAKS:
- You can use SetCPU (thread - here) to enable better control of CPU as it goes (also on project's google page):
Stability
Minimum (MHz): 19.2
Maximum (MHz): 528
Governor: ondemand
Performance
Minimum (MHz): 128
Maximum (MHz): 614.4
Governor: performance
If you have the possibilities, you can support the developer by buying the app on Google Play
- For a easier use of Rotation Locker go in Settings>CyanogenMod Settings>Input>Long-Press menu settings>Choose behaviour>Custom application then Select custom application>Application>Rotation Locker
- Also for a easier use of Advanced Task Manager go in Settings>CyanogenMod Settings>Input>Long-Press home settings Uncheck "Show Recent apps tile", check "Use custom application", Select custom application>Applications>Advanced task killer free
- You can change the lock screen into a less-laggy one by going in Settings>CyanogenMod Settings>Lockscreen>Lockscreen style>Rotary(it's my favourite)/Sliding tab/Lense
- Go in Auto Mount app and tick "Enable SD Card Auto-Mounting"
______________________________________________________________________________________________________________________
Changelog

- Changed Nemus Launcher to LauncherPro
- Changed QuickPic to Picturen Lite
- Change Maxthon Browser to Boat Browser
- Included Advanced task killer

25.10.2012 V1
- Initial release
________________________________________________________________________________________________________________________
NOTE: I am open-minded to any improvement idea as long at it's still in my understanding limits.
Many thanks to be there with new projects.
Let me tell you that CPU Tuner works properly on ZeamDroid but on CM7.2 doesn't because of CM CPU controller. For CM7.2 the best option is not the CM CPU controller the best choice is SetCPU.
Best.

True, but SetCPU is a paid app, so even though I can pay it, I'm not allowed to include it in my ROM

Well, the version 2.24 is free for xda user: http://forum.xda-developers.com/showthread.php?t=505419
.
The reason why CPU tuner doesn't work is because of CM CPU controller. But CPU Tuner is the best frequency switcher for our Xperia X1.
Dear ady_95
Thanks a lot, for your nice work, could you please tell us, what is working and what is not ?!
and what about the battey life?
thnx dude !

I edited the name and about the google drive link, it's now fixed...(so please, if you can, remove the link from your post, because I don't know what's the downloads limit - or if there is one) also, the DL speed on Google Drive is bigger
Well, guys, it seems the base ROM and the kernels had not changed in the last weeks so until an update comes I retire and go back to WM because my camera is f**ked up and my X1 is the only replacement, I have to manage a high-school radio (from everywhere) and also I have semestrial tests in the next 2 weeks.
I will still follow the forum and when a major update will come, expect for me
See ya!
Hi, this ROM works great for me, very good performance, but after awhile it's not letting me make any calls. Whenever y try to call someone it just shows in red "Call Ended 0:00".
Wish I could go back to windows mobile as well, as I love using my X1, but I wouldnt use it if i did, as there's no Whatsapp or decent gtalk app on windows mobile.
Anyway, thanks for the ROM, great work.

Now your turn:
Remove twisted Home app
Restore stock AlarmClock
Underclock and overclock
IZS tweaker
Fast mounting of SD card on booting
Headset profile (bcoz without profile, when connecting headset, if the sound is full, the earphones may damage)
Some best sound engine like Sony
Additional fonts (Love)
Circular battery percentage like in Zeus
Battery full and low notification with optional sound (default indications not hearable, very low volume)
Resolve deep sleep issue, Deep sleep is not working sometimes. At night charged to 100% at 11 p.m., next day morning 7 o'clock the battery percentage 96%, I checked and make sure no background apps.
Flash make work on IZS
Built-in file manager, ES file explorer (a lot improved in latest version), built-in TeslaLED,
Built-in Jelly Bean 4.2 Keyboard with Swype
Mainly in-built Call Recorder facility, it's not possible because free versions don't work as we expected and paid apps are not allowed to merge in ROM as per rules and terms, I think.
If it's possible to add Call Recorder, I have one name of app that is fully working incoming and outgoing calls. i.e. Call Recorder (https://play.google.com/store/apps/details?id=com.skvalex.callrecorder&hl=en)
Overclock cpu to dual core.
As i posted as soon as i saw Huexxx is back : SWAP. I said it to be implemented but it doesn't have to. All one need is a compatible kernel. If you have one you can even use third party apps. I already have one but i can't use it due to incompatibe kernel. Here is a free app from the same dev for checking if your kernel is compatible (it doesn't work with IZS v0, i've already checked, you can try if you are using other ROMs) :
https://play.google.com/store/apps/...51bGwsMSwxLDEsImNvbS5yb2Voc29mdC5tZW1pbmZvIl0.
PS: If you want this topic to be useful i suggest keep these things to features that aims for performence, stability, or new useful things. Stay out of personalisation, themeing, apps that can easily be installed later as much as possible. "4100 points in antutu", "compass app" , "Task manager and laucher from V30i", i am sorry but these are neither useful nor really necessary. We all want Zeus Tweaker to return so other than that if i have to give an example for new "things"; i think that would be "Halo" from PA. It's open source. There are other things before it comes to that but it will be more useful than a lockscreen request.
I agree

I agree! I prefer a ROM as clean as possible and, could be useful an AROMA innstaller to do some personalizations from the first install... but thast not important, like themes, some apps, crossbedder, Awesome blue beats, actions for the G button...
But al thoose things IMO are weird to be included into the ROM... much better it to be as clean as possible, i prefer to rebuilt the ROM befor iflash it with my prefered apps and mods.
I believe that is much more useful that Huexxx works on the kernel to improve performance, maybe some gobernors/schedules, frecuencies, OV and UV... like in ZEUS ROM.
Also the built in Tweak to improve SD card read speed.
The bug in the data managment menu, where apps doesent appear.
And as far as i can think now thats all the ROM need.
lawl, can i post this on 9gag?

Trickster Mod app

Does anyone use the Trickster Mod app on stock kernel? I have the donate version and i take advantage of the charging LED light. If so what, if any tweaks did you try? I also use the multi core power save tweak set a 2. For anyone that may know, would using titanium backup to convert Trickster Mod to a system app have any advantages?
Doubtful. AFAIK Trickster mod just makes the changes at startup, it doesn't need to run all the time.
BTW I have both enabled, the multi core power saver and mp-decision.
Cool to know it works with the stock kernel. Is there a noticable difference in performance and does it give you better battery life?

Click to expand...

It's tough for me to say if it gives better battery life due to a lot of changes in settings, e.g. greenify, app permissions etc working in connection. I will say it doesn't hurt. When my phone is asleep I lose about 1 to 1.5 percent per hour which is okay with me. Performance is fine for my needs. Plus I like the LED feature to know when my phone is charge by the status of the green light without having to psychically unlock the MX and check. But to say how much of a difference is hard to tell without setting everything else back to default and just using Trickster.

Battery Drain
Hi,
I have some issues concerning the battery drain. As I dont use the cellular connections, I turned on flight mode and enabled WiFi manually. I also setup the WiFi to turn off while the Tablet is in StandBy. Still I an loosing about 1% battery per hour. Within the old 4.1.2 ROM, this was far better. I just wanted to check if others experience the same and this is normal with KitKat or if there is some setting which ensures an improved behavior within deepsleep (asuming that my device will go into deepsleep,didnt check).
Thanks for all the answers and a big thank to all the guys behind this rom. I really like it!!

KitKat for our device is not a really good build compared to JB. I suggest you to try Ultra Power Saving Mode to reduce the drain caused by other apps and system services.

Yeah, I guess I could do that, but the ultra power saving mode has a gray scale theme and also only a limited number of apps which can be used. Thats like buying a BMW and then replacing the enginge and putting in pedals instead.
My guess is, that the device does not properly enter deep sleep. Within deep sleep, the device should not waste more than 1%-2% overnight.
How can I check if the device enters deep sleep?

I meant that you can do this to reduce the drain when you don't use the tablet. Anyway download CPU spy and check deep sleep. I suggest you to use greenify to freeze background services and improve deep sleep time.

According to cpu spy deepsleep has never been used. Is this a kernel issue? Is there any way i can activate deepsleep, mayby with an exposed module or app?

Sounds like an app wakelock thingy. Use greenify to stop bg processes maybe?

I also thought about a wakelock. Well greenify tells me that there are no bg processes to be stopped. I also used 'ds battery saver', which worked well on my i9001 and should force the device to go into deepslepp, which did not work.
I will have a look at this tomorrow. I guess i can use adb to check the wakelock (suggestions welcome

not my strong suit (I'm just a tinkerer, absolutely NO programming skilz).
Good luck and please keep me up to date, and I will look into it myself and compare to my stock build.
Hallo @smegg, which one is more stable, this rom or N8020XXUDNE4 v2.01?
What is the different between this rom and N8020XXUDNE4 v2.01?
Thank you for your great work

Battery Saving Tips Root / UnRooted

I just wanted to make a quick rundown of things I do to phones, even if they have a large battery.
- Go into app info, then battery, then enabled "Background Restriction" for apps that don't need to have fast notifications. I do this for apps like XDA, Feedly, Amazon etc. Given enough time Adaptive battery will do this for you, but I go in manually for any new apps or ones that I still might use frequently. (UnRooted)
- Download Naptime and enable aggressive doze. Also play around with the experimental features. I disabled location when Doze mode is enabled. (UnRooted)
- Download Servicely from the same dev. I disabled apps when my screen turns off and whitelist phone, messaging apps and other high importance apps. (Root)
- Use Tasker to automate Battery Saver Mode when your screen turns off and disable it when the screen comes back on. Naptime can also do this in the experimental settings, but I use Tasker to trigger it based on conditions like battery percentage, etc. (UnRooted)
- Install the Universal GMS Doze in Magisk. Combining this with Naptime really helps for standby. (Root)
- Install AdAway from F-Droid. This is a small thing, but less data use for pulling ads means better battery. It's a stretch, but the other benefits are no more ads! (Root)
This is what I've got done so far. Once custom kernels are released I'm going to use the Franco kernel app to make per app customizations to underclock the CPU and GPU for apps like Messages and other lite apps to really squeeze more battery.
With these optimizations I can easily make a full day. I haven't gotten a solid SOT number yet as I change in my car through Android Auto most days, but I really want to test a day completely off a charger to see what it's like.
Again, these are things I do on even large phones like the OnePlus 7 Pro and it's almost doubled my battery life on phones. Plus, these are set and forgot things and should only require a little bit of setup.
I hope this helps yall eek out some more battery out of our awesome devices! I can start to use the phone without worrying about battery anxiety.
Or you can just enable battery saving, and don't optimize apps you really need.
That's true, and I have it enable when the screens off. I'm not sure is restricting background use AND battery saver are doubling up and helping save more battery, but I want the option to have a light theme, so restricting battery for apps gives me that option
