i have been using xperia P for more than a year and um quite happy with it except one fact which is the battery drain issue. my phone is running stock JB with nemesis 6.3 kernel and some other excellent mods.bt when the battery level is below 40-30% it suddenly falls below 20% both with the stamina mode on and off! i have tried almost all the stock based custom roms and this issure persists.this doesnt happen whn the battery level is above 40%, i have been facing this issue since i bought it! i have gone through many threads but no helpfull solution so far.any suggestion/help on this?
There's no way anyone can predict what is causing your battery issues without posting some more info. If it has persisted across different roms and kernels then the issue is most likely the apps or tweaks you have installed or the battery is going downhill. The built in battery stats in the Settings are about useless. I suggest checking out some advanced battery / wakelock detector apps like:
GSam Battery Monitor
https://play.google.com/store/search?q=gsam battery monitor
Better Battery Stats
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
Wakelock Detector
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
Without a few days of keeping track with an app like that, saying I have bad battery life is about as effective as going to the doctor and saying I hurt, but not telling him or her where at.

Currently on checkrom revolution 1.0 KI4 with hardcore's latest speedmod k2-8. Have had this phone for ard 5 months now and u can call me a compulsive flasher since I'm always flashing the latest roms, kernels and firmwares.
Throughout these 5 months, this overnight battery drain issue has been bugging me relentlessly, regardless of the firmware or rom used. Typically my phone will be off in the morning if i leave it at anything below 50% charge when going to bed. In contrast i've read of many accounts of sub 5% overnight drains that has lead me to suspect some kind of mistake on my part rather then a fundamental flaw in the design of the phone/software. Would be great if the xda community could assist by giving some insight into this matter, for in sure some of you might be/have been experiencing the same issue and might have solved it or are awaiting similar insight as well.

no its not normal. I lose 1-2% over an 7-8 hour period when im sleeping.
Install betterbatterystats and see what your wakelocks are over night. Something is obviously keeping your phone awake. The usual culprits are being signed into latitude or facebook chat.
i would suggest either change kernel or better yet change roms...kernel i would suggest ninp 2.0.5..stable and good battery life..also if you use setcpu i can provide you with frequencies so you can test it..message me so i can give them to you..regarding betterbatterystats i would not use but as skimmingstones say use it and see what your wakelocks are cause ur stats do not sound right buddy
Jeez! 40% overnight? I once had 8/9% drain overnight and got annoyed. Install Better Battery Stats first to see what apps/processes are causing the wakelocks. Then go on to change kernel and SetCPU etc for further betterment, but at first see what's going on background, with the help of BBS.
Post up screenshots of battery usage please.
My sister was loosing 40% each night turned out to be the Hotmail app not sleeping!
LOL 40 % !? your phone is the best drain phone ever :/
maybe U can set your display to low brightness and look of your phone goes to deep-sleep mode (CpuSpy)
Dude,
Try also to calibrate battery.
Look at my signature.
not normal for me lolz
Battery drainage for cm7 fxp115
I installed it yesterday and fully charged it
by morning it was at 39% :-\
im postiong the screen shots or bettery battery stats..
Well the battery drainage depends on a lot of things like services running on the background or sync services enabled etc. But you can also try this kernel and see how it goes http://forum.xda-developers.com/showthread.php?t=1549221
I have been testing the 2.7 kernel since yesterday
And sync is off
As You can see ...the battery usage is from Gps location service
and the graph shows that the phone was awake always :-\
Well then shuting down the GPS when it's not needed should lower the battery usage of the rom
Settings>location&security>use gps---off
i already tried it
cant figure out what it is using
Well once again I recommend you to try with the kernel I posted before and well report the issue on the roms original thread as it may be a bug the developer can fix on the next release.
Hie guys, I just woke today to see my phone was off and when I switched it on the battery was @17%, from the battery stats in settings it shows my phone switched off after 2hours of me sleeping. So what can really make a phone lose 74% battery whilst it's OFF??!!
Help me or you can paste me a link to where similar problems have been discussed.
Thanx.

Download a battery calibration tool off the market and use it, I have had this happen to me before where i would lose over 50% of battery life just by restarting my phone, and it would gradually go back up.
Also check if their are any updates for your rom and os you are running

Probably a pointless exercise since it's been proven you can't "calibrate" the battery in an S2.
I've had something similar happen, I was raping my battery with a torch app then restarted. Before the restart I had about 90%, after it was around 30%.
Could it be a sign of the battery failing? I've not had any real problems otherwise..
Perhaps you have wake locks? Purchase better battery stats or download it using the search button.
A high battery drain is often a limiting factor for a great user experience.
With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions:
- Spot drainers based on detailed information about the root cause
- Use the online Knowledge-Base to find how to reduce or remove the wakelocks
- measure the effect of actions to reduce drain
- detect changes in the awake/sleep profile and quickly find the causes (rogue apps)
Hi,
I installed Gummy 1.2.0 on my vibrant. The first day or two I was getting amazing battery life. For instance with light-medium use, 30% of the battery was gone in 12+ hours, I was amazed. When I was getting this type of battery life Android system was using about 6-7%.
I noticed that as time passed, the battery life started getting worse and worse. I noticed that the Android System was eating up more and more battery even when it was supposed to be in deep sleep. Now Android System is using almost 40%
Has anyone else had the same experience? Great battery life changing to mediocre battery life in a couple of days.
Please advise.
Thanks!!!
I suggest you get Betterbatterystats and that way you can see exactly what is causing the problem. It is available in the market, but there is a free version here in post 2. IIRC the AOS taking so much of your battery life is bc of some errant process that is constantly drawing/polling on the system and causing the dismally high % of use. Find the app, fix it and your problem will be solved.
finally found a thread on this issue after posting
http://forum.xda-developers.com/showthread.php?t=1748301
sorry mods, pls delete
Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I have been experiencing some serious battery drain issues. Looking at my battery stats, "Android System" is responsible for over half of the drainage. These are the only apps that run constantly besides those which the phone requires to operate:
- SetCPU
- HDWidges
- The Weather Channel
- LBE Privacy Guard
- avast! Mobile Security
other phone info is in sig. Any insight/advice??

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

So this worked for you? I am having excessive battery drain with my Telus S3?

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
