Well i instaled Gin2JB with Night elf 10.1 exp and i have too high drain ... i almost get 50mins onscreen time
I dont know what to do anymore..i reflashed stock gb then installed gin2jb and same drain ...My phone gets into deep sleep but i still get 8 battery/H consumed...
try flashing other kernel.
battery drain is usually because of kernel.
Can you suggest me other kernels than nightelf ?

If you are not specific with rom try some kitkat rom with the kernel given it zip. I'm using carbon rom, work good for my usage. I get more than a day of battery.
Tried lupus , tried Carbon rom , all eat 50+ battery per hour in this progam https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
when i`m playing and i have 3G on
I even changed basebands , i`m on 77 now , been on 64 .. i see the results tomorrow , after this night..I barely get 30 mins ontime screen ... i have checked with better battery stats , when phone is in deep sleep still consume 5% per H
At how i use my phone i need to charge it once every 5-6H... that's so sad.

Did you try the Night ELF's 10.1 lite version (Its the version other than experimental version)
Try that...your problem may get solved because i also faced the same problem while i was on Gingerbread many a times.
Change your kernal after once you flash any of the stock rom with its kernal.
Your problem may get solved as mine got solved when i encountered the same problem as yours.
I use to use the codename rom with nightELF's kernal
Hope this helps
hit thanks if you find this useful
So you say that i should install Night ELF's 10.1 lite version on Gin2kitkat ?

Ya my friend, give it a try.It worked for me so that might work for u too.
Also if u want to use a Gingerbread rom then Codename Is a good rom which u may try out if u like to
And install that kernal after you intsall the stock Gingerbread ftf of sony including the kernal.
Might solve any issues if your phone is having one.
Hope this helps

Battery Drain comes from few factors.
1)You probably use alotsa apps in your X10S
2)Many Apps/Background Services active in Application>Running Services
3)Battery problem
4)Type CPU Governer used
5)X10S is 2.3.4 version, need compatible kernel like KCernel for 2.3.4, some DooMKernel is for 2.3.3GB Stock ROMs
Solution options:
1)try go recovery and click "Wipe battery status (find it somewhere)" then reboot your phone
2) Or reboot your phone and check is there problem remains?
3)About Kernel for X10S, DooMLord or Champ's KCernel shd work ok,
perhaps you change your phone's governor via SetCPU or ROMtoolbox, cos different governors, different battery usage.

To Check Battery Health (I tried in 2.3.7 DonutHD, 4.0AOKP, but didn't try in X10S in past)Anyway, try whether is this works and tellme your result
1.Click Phone
2.Dial *#*#4636#*#* and it should direct you to testing. These options should show i guess:
-Phone information
-Battery information
-Usage Statistics
-Wifi Information
3.(Go To Battery information>Battery Health if can) If show ''Good" means ok, works fine.
4. OR you can find Battery Apps to check your battery status.
Wifi modules here find the compatible with KCernel you choose, i got from champ senior ]Hope Helps Cheers

X10S drains battery
Hi guys,
Pls help me....TIA
I have installed X10S as mentioned in this link: http://forum.xda-developers.com/showthread.php?p=25505738
also flashed the battery patch....
but it drains the battery very soon....
it shows my battery has like around 20-30% charge and suddenly it becomes 0% n gets switched off....
when i switch it on it shows ~19% n within 2-3mins it gets switched off....
so, i installed the x10s again n again but same prob exists.....
i just have 2-3 apps or games installed....!!!

Battery always at 100% after flashing and removing nAa kernel.
Device:Sony Ericsson LwW
Issue:
Recently flashed nAa's kernel 3.4.45,ROM CM10.2 JB 4.3 alpha 20130809.
After a while decided to revert to my previous config
Kappa 1.6 Kernel and optimax v2.0 rom using a CWM backup
After doing so,my battery percentage is stuck at 100% always,restarted it several times..like 6h and still 100%...
The battery voltage is fine though,4070mV-4091mV is fully charged but the meter shows 100% even at 3600mV.
Even when the phone is completely dead(red led blinkin),i connect the charger and the led immediately turns green.
Basically the meter is stuck at 100%,but the battery actually charges as i can see the battery voltage goin up..
What i have tried till now:
1.Discharging it completely and charging it again
but the phone shows 100% immediately on connecting the charger..:crying:
using battery stats wipe from CWM,using apps from market - NO USE
2.Flashing extended stock kernel,no use
3.Installing optimax v2.0 instead of using the CWM image,no use
4.Installing Stock ROM (build 4.1.B.0.587),solves the problem which means its not a hardware issue.
but i dont want stock rom...
whats wrong with optimax ROM which was workin perfectly before i flashed nAa kernel?
5.Flashing the nAa kernel again along with the JB rom i tested solves the issue,but the ROM is not suitable for my personal use.
can somebody please solve this issue...?
I will attach a logcat if necessary...please help me with this...
Okh try few more things..
#Download battry calibration from market and try to calibrate it..
#in cwm revovery mode wipe the battry stats..(Dangerous method and im not sure it will work)

i already mentioned that i have tried it and its not workin...

Please dont ask me to recalibrate again..

I tried but still no use..kappa kernel still has 100% battery issue..
and every other kernel works fine and reports the battery percentage..
What could be the reason?
@nobodyAtall Can you please help me out?
its kernel bug. like in test kernel of kappa just re flash
Finally Solved
Sorry for the title,NOTHING TO DO WITH nAa KERNEL
Ok guys i finally managed to figured out the solution after weeks of struggling...
Its quite simple..
1.Flash a different kernel(i flashed extended stock),charge your battery to 100%
2.Flash kappa kernel before your battery drains below 90%
3.Tada!!! the battery bug is no more!!!
I even managed to figure out why this actually happens..the battery meter value is estimated by a chip bq27520 manufactured by TI semiconductors...The datasheet of the bq27520 describes the charging algorithm which estimates (and calibrates itself ) the battery meter percentage at 4.2V and 3.0 V,Since 3.0 V is not possible..4.2 V is good...
I guess kappa kernel doesnt support the charging algorithm of bq27520 and hence it is unable to re-calibrate itself and gets stuck in last state..,whereas stock kernel supports the chip and thus solves the problem...
If first time it doesnt work..try using your phone with the stock kernel for one discharge and charge cycle and then flash kappa kernel..
BUT FLASH kappa kernel ONLY WHEN BATTERY IS ABOVE 90%
hope this helps anybody else having the same problem...
anyways thanks for your efforts guys,Finally peace!!

Pls keep nAa kernel flashed and then flash Super JellyBean v6. Then let the phone boots. After that you can flash any kernel or ROM or restore your existing nandroid image. this will help you.
Thanks!
I have opposite problem
When I flash stock ICS kernel I have 100% battery problem but when I flash NON stock kernel IE vengeance LUPUS, FXP,FUSION or STOCK GB etc problem is gone.
I notice an error with the bq27520 driver with dmesg could my battery controller be faulty ?
is it compulsory to reflash kappa kernel
pl reply
I am also facing the same problem
Hi,
I have a Xperia Arc and I have same problem when I'm fixing battery I'm losing wifi
I don't know what should I do
if flashing not to be solved the problem ,, try this app , with this app i never stuck on 100% again

How is that working?

anyone can confirm this if it's working?
i want to try cm11 but i don't want to have that kind of bug if ever i decided to go back on my stock ics.
i'm using LWW
this thread helped me to solve my batter stuck at 100% by doing the steps below:
1. flashed stock ics ftf file
2. turned on phone and still got the battery stuck at 100%
3. turned off phone
4. flashed the lupus kernel with stock ics rom
5. turned on phone and the battery stuck at 100% issue was solved
6. flashed kappa kernel which is my preferred kernel
7. installed my preferred ics rom
thanks to the thread author !!!!

This 100% battery bug is present on stock kernel itself. But it manifest only when you switch from cm 10 or 11 to ics. Only known kernel not to have this bug is Mesa 4.8 kernel. For some stock rom flashing eliminates the problem but reappears suddenly. My request is to first flash stock rom, then flash mesa kernel, then install desired ics based any rom e.g fluroscent feather rom & then after few days kernel of your choice eg doppler kernel, kernel panic etc.
This always solves my problem in XMP sk17i.
Since the kernel for ics are based on stock sources (except mesa), all tend to have the same problem. Mesa kernel fixed that problem long aaaaaago. See the changelog:fingers-crossed:

Hey guys..
I bought a galaxy tab 2 two weks ago from a friend who also used it for just 2 weeks !
It worked fine but recently I face a problem with the battery !
The battery drains to 40% after playing fifa 14 for just 1 hours with 30% brightness !
I searched for a solution in this forum and I read a threat about battery calibration which said that I shall charge it to 100% shutdown for an hour , restart it and use it until you get 40% battery and shut it down for 5 hours etc...
Anyway I tried the calibration method but it doesn't help and probably the situation get worst because this morning I used it until battery drained to 80% then I resart it and I found that battery drained to 34% !
I find many calibration app in googleplay but I'm not sure if it will help me in my situation or not !
So would anyone please help me solve this problem ?
thanks previously ( sorry for my bad english )

Well, calibration apps and doing it manually [ie .messing with the .bin] won't work due to it not being rooted. But on that note, I don't think you would have any reason to calibrate it. To my knowledge only flashing ROMs and things of the sort can cause it to be out of calibration. [not 100% sure though] Normaly You would have to charge to 100%, then let it die, without any charging. Go from 100% to 0% then 0 back to 100% in one charge.
Hope ya get it right. If anything ask him if he still has the receipt if he got it new. Could possibly use the warranty.

Well, try a calibration app 1st. If that doesn't work I don't how to "fix" it. You could do things to reduce battery drain though. Lowering the CPU max frequency, a powersave governor, undervolting the CPU, keep brightness to a minimum are good ways.

I tried 3 but it still the same ! I will be so thankful for you if you give me names of good apps for lowering the CPU frequency ! I'm actually starting using battery doctor ! Is it a good app ?
It helps to a degree, but I'm thinking your problem is the battery itself. Was it treated badly? Like leaving plugged in for long periods of time or left in really hot cars.
Also turn off location and Bluetooth

I haven't tried it myself, but I have heard that it's a very good ROM. So I'd say, go for it!

Thanks for being always here to here . As I told you I'm an amateur and I don't know how to install it . I'm also afraid from Ram usage of this rom ! My brother have a samsung galaxy s4 with 4.3 android and its ram usage is 700mb while it is stable and in galaxy tab 2 I only have 769mb ! So would I have such a ram usage if I Install this rom ?

Bro stock rom is know to have battery issues and ram leaks as it has a lot of apps and unwanted files (commonly called as bloatware )
1st i noticed tha tu have 769mb ram so you are still in stock kernel (i guess) first flash a new recovery from here http://forum.xda-developers.com/showpost.php?p=51314025&postcount=296 next flash Slim Rom(u can use any rom but as the name suggest it is verry fast and smoot and also hasa good battery management) from here http://www.slimroms.net/index.php/downloads next flash gapps from there itself .next flash a kernel such as Agni (highly recomended)

First thing you should know, you don't havta say thank you all the time, just click the Thanks button, that's what it's for.
And I actually installed PAC ROM today. It's an awesome ROM with a lot of cool features...
As for RAM usage, I dont think that should be a problem. The ROM should be optimised for your device, so it won't use 700mb at rest.
Give it a try, if you find it's slow or laggy, I can suggest more ROMs. :good:
(<---Remember to Thank me if I helped)
I would use CM10.1.3 for battery life, as I used to get 1% lose overnight. (I use SlimKat now which may be not as good in the battery department, but for me the latest OS is essential, but that's just me.)

Here's what a senior member said :
"Borther. I would like to quote one thing first of all; all kitkat based ROMs are battery suckers. So you will not get good battery backup as you might have seen in 4.1.2 or 4.2.2. Xposed framework consumes lot of RAM,i prefer not to use it. PAC ROM is just like another KITKAT ROMs that provides loads of features but with an inefficient battery backup. You will see huge battery drain yourself. I did tried all Kitkat based ROMs. Even all kitkat based ROMs have shuttering/noise sounds while playing some games like Real-Racing 3 etc. I suggest to go with Stock ROM 4.2.2 based on your region or cm 10.2 based ROMs(if available). Root it(if stock) and remove all the samsung bloatwares from it. Then you will not get any kind of battery drain or Lag while playing high-end games. But ultimately choice is all yours."
Thats why am still confused ! So what is the usage of ram at rest ?! You install pac rom kitkat or lower version ? What about battery , did it drain too fast ?!
And how did you install it please !? Am running sg tab 2 p3110 with SuperSU root and the latest version of philz as a custom recovery

I have a p3110 with latest philz recovery and dual booting pac 4.4.2 and Stock 4.2.2 with Next blackhawk kernel
OCed at 1.2GHz and both data and cache formated to F2FS and
1) I have no Lag on both the roms(primary and secondary)
2)1% loss of battery from night to day(9:30 pm to 5:26 am)
3)Play modern combat with no glitch
so i suggest you to do that!!

I installed PAC(KitKat, latest nightly) on my GT-N7000(Galaxy Note) which has 778mb available RAM, and I get around 380mb used after clearing recents, and 355-ish after the phone has been at rest for some time. Mind you I haven't got too many apps installed which have background services, though. But I'd still say it's good RAM management.
But as for what you should do, I think you should take @iamashwin's advice...He knows what he's talking about. @lokesh.3440 suggested the stock option too, so you really should try it. :good:
Thank you all for support ing me ( pressing thank bottom is done ) but I decided to install cm 10.1.3 since it is recommended in many threads for battery life . Would anyone please explain to me what is a tabletUi patch ?

I'm not sure...I would think it's a patch to give you tablet UI (I know, I know...I'm a genius), but since you own a tablet itself...
I think it's some kinda fix for ROMs for tablet ported from phone ROMs...
My phone never goes to deep sleep. I installed the BetterBatteryStats app to see what is making this problem and so far here are the results (in the attachments).
PS: I am running an 2.3.6 Android with custom ROM (SuperIceDroid and HellLock kernel) and I have rooted the phone.

I wanted to use the recommended kernel for this ROM which is CM Specific Basic Kernel v3.0, but I cannot find it anywhere to download.

there are only download links for version 4.0, but the ROM won't boot with version 4.0...
