You can instal the Devil kernel and activate "Deep idle"

Also try JuiceDefender

Sorry Bit i use both deep idle and also juice defender, i really dont know what to do!

I'm going to say it's the kernel as I'm running the standard one that comes with Cyanogenmod 9 and I don't have this issue. Actually, my battery is above average.

There's a big issue with i9000's running hot and having high drain at the moment. I'm not sure what has caused it on mine. It seemed to happen after I upgraded to CM9 but I have flashed back to 3 different varieties of stock ROM/kernel and same story. Gets really really warm when under load and battery drains at the rate of around 20% an hour when the screen is off, phone is in airplane mode and NOTHING is running (i.e. in deep sleep).
At a real loss as to what to do about it, I've seen a thread about 500 posts long on the official Android forums with i9000 and i9100 users all expressing their frustration over this.

In your battery stats what is showing high drain? Also instal better battery stats and run it for a while to drill down what is causing problem

Hey, appreciate you are well intentioned but have been through all possible diagnostic steps and all documentation/suggestions I can find online. I am an experienced IT pro and have tried EVERYTHING that has been suggested ANYWHERE by ANYONE and there is no fix.
Screen is showing the most, followed by MediaServer then Apollo player. Problem is the battery drains when all those things are killed (i.e nothing is running phone is in deep sleep). This happens overnight when nothing is runnning at all. The battery stats do not change. The processor does not show anything as being used.
Many people have already been through the diagnostic steps and there is simply no answer.
Refer this thread:
http://forum.xda-developers.com/showthread.php?t=1635614
There is a reported bug on the official android site as well but I'm on my work PC and don't have my history from home to drag it up again.
Basically symptoms are
- Battery drains exceedingly quickly ~15% when idling and 25% per hour when in use.
- All diagnostic tools show nothing running or using your battery or CPU
- Phone is warmer than usual in any state (i.e. idling/charging/under load)
- Most folk I've seen with the issue have flashed to CM9 at some point but that is not a consistent truth.

Another screenshot that shows that the mobile standby consumes almost the same of screen

In your first post, i saw your "señal de red móvil", is very poor. Have one or two little line green ( best signal ).
As is the signal coverage where you are? The signal is good or poor?
and when you get with wi-fi on, the battery drains very fast.
Sorry for my poor english.

its poor man, thats why i want a battery saver modem, and the wifi battery drain its horrible, please help me!

Did you have this problem from the beggining? I am using Dark Knight 3 ics, and for many months everything was okay. One day, i had battery drain. Even after a reboot, the drain was there. I reinstalled and it works fine again

guys, now i have a almost one full day with normal use, i dont know if i can get better results or whatever, but im happy with this result, i've done it downgrading to GB and i'm happy with it, but i would prefer to stay in ICS, but well im not bad with GB.

Is this normal battery drain?

Hey guys I get good battery when the screen is off. But whenever I use it, it seems like it drops pretty rapidly.

Depends on what you did during that period.. If the processor was running at MAX frequency the entire time, yes thus might be normal.. Also as I notice from the screenshot, the screen is always in in that time frame.. So you deduce from this

No. It's broken. You should send it to me.

Hi,
Thats an abnormal drain. Try restarting your phone and seeing if the problem persists. Also note that the ROM you are using is still under testing and not a finished product so might experience some difficulties. Consider shifting to a more stable ROM if problem persists.
Having said that, battery drain will depend quite a lot on what apps you have running in the background and your settings.
Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.

[Q] CM10.1 and v20A general battery duration

Hi,
I'm a bit disappointed to see my battery lasting max 10 hours since i upgraded to CM10.1
Coming from LG original rom, i can remember it lasted at least twice.
Am i missing a point or something ?
Do you advice me a kernel other than CM10.1 one ?
Here is my reported usage:
Android platform for 40%
My runs for 15%
Display for 14%
Inactive phone for 10%
GSM sleep, Wifi, Multimedia for 4%
Thank you for your help

I would suggest you to let your battery complete cycles. That means charge your phone to 100% flash any Rom then let it discharge to 5% or 10% but not below 5% complete this cycle for 3 times atleast to check the battery usage and behaviour of your Rom.
If this does not work you can try to change the kernel and do some experiement whatever is suitable for you.

[BUG] Battery Bug for Stock 4.2.2

THIS BUG CAN DO HARM TO YOUR BATTERY! BECAUSE YOU WILL NEVER KNOW WHEN THE BATTERY DRAINS!
As we all may encounter the battery bug after upgrading to .423 fw. When one restarts his phone, he has chances that the battery level of the phone rises (e.g., I turned off mine just now at 26% and turned it on showing 51%). This has been confirmed by many users in the forum, so I believe it is a firmware level bug of 4.2.2.
Is there any one willing to pay some time on fixing it? Coz this is a quite crucial bug for us, we dont know when will our phones automatically turn off! Thanks in advance
I believe its not a caliboration thing coz we also upgrade or wipe our devices before, and no such thing happened. I think its a firmware or kernel level bug. Does anyone who flashes a custom kernel also encounter the same problem?
It seems that Spanish FW is free from this bug.
http://forum.xda-developers.com/showthread.php?p=43261281
plz report your rom or base FW in the reply. Thanks.
[NEW EDIT]
It seems that I fix the bug. The battery jumps when the phone restarts, so I think there is something during boot which causes the issue. I delete the XZDualRecovery, and test the phone several times, and its fine!
Deleting XZDualRecovery might be a temporary fix, so you can choose what to do
[NEW EDIT 2]
someone reports that they dont encounter the bug and believes that its the calibration thing. i declare again that i DID the calibration and the issue was still there. for me, at least, deleting XZDualRecovery fixes the bug. plz report more details in the reply, like fw, root or not, recoveries. Thank you

I don't think there is a bug here.
Never happened to me,cause i did full wipe while flashing.
Maybe it happens only for users that didn't wiped everything.

There is no kernel for 4.2.2. DoomKernel supports fw before 423. Correct me if Im wrong. Also in LB and know not much about custom kernels.

yes this issue exist. it happened to me when i updated to this new 4.2.2 also i have black dots in camera and the back cover of my xperia z is not correctly glued. i hate sony right now

I have the exact same problem, went from 26% to 52% after reboot... Is this bug bad for our battery? If so, maybe I'm flashing back to 4.1.2.

hello all me too experienced the same problem but I successfully regained my battery life. Here is what I have done....
1)First I drained the battery fully until mobile gets switched off
2)Then I left the mobile to cool off for half an hour
3)After that I charged the battery upto 100%
4)Following this I switched on the Mobile and did the battery calibration by using 'Battery Calibration' app
5)Again I fully drained the battery and charged it again to 100%
Now the battery life seems good. I checked this by using WiFi whole night....battery lasted overs 12hrs

This is exactly what I concern. I dont know when my phone is going to off, and it could be big trouble when there is no access to the charger.

Maybe we just need to recalibrate, drain battery to 0% and fully charge it to 100% while the phone is turned off.

plz give some feedback if it works

I experiencing the same issue. 2% to 55% after reboot. wow... 4.2.2 doesn't bring anything for me to consider to keep it. so back to 4.1.2 (.4.3.4)
But one thing for sure (never discharge a lithium ion / polymer battery from full to 0 they don't like it) you could do that with nickel cadmium/ metal hydride batteries ant they really thank for that if you keep doing that you just kill your battery before its due time.

Xperia V - Huge battery drain (Google Services)

My Xperia V was draining much battery while sleeping, so yesterday I flashed cm-10.1.3-RC2 hoping it could get better.
But it's still draining almost 30% in a period of 8 hours, while I'm sleeping.
I can notice a huge drain caused by Google Services and have already greenified some apps.
It can't be normal, right?! Could someone help me?
Despite this problem, now I have a really better smartphone... So, thank FXP and, please, keep supporting Xperia V. :thumbup:

Not sure if this question belongs to be an own thread...but ok. here we go.
from my experience with Cm i can tell you, if you want better battery life, then you maybe should use a stock firmware!
I used CM and AOKP some weeks before, but the battery drain wasnt normal, not to say horrible.
But this is my experience. You should ask in your CM-Rom Thread, or CM Q/A Thread i think.

I'm a new member and I couldn't ask this in CM thread
I understood what you've said, but even using stock rom I was having that percentage of draining at night...
Do you have a Xperia V?
Could you (or someone else) tell me how much draining is considered normal in the period I've mentioned before?
Sent from my GT-I9300 using xda app-developers app

30% in 8 hours means that on average your battery will last a day.
That is perfectly normal.
Also, if you keep flashing stuff and installing apps then it drains battery quicker. Leave it alone for a week and see if it settles down.

Sorry, i have a Xperia T.
in the xperia T thread of tilals unofficial CM build (development section) someone mentions also such problems:

30% in 8hours sleeping? horrible....but you are right, let it settle, fmlogin

Omg, my Galaxy s3 loses only 2% in the same period while sleeping, it's a BIG difference
I had been facing this problem since I bought this phone (2 months ago), that's why I tried to flash CM yesterday... So, I think that nothing will change if I just wait...
Anyway, thank you guys...
Sent from my GT-I9300 using xda app-developers app

apologies, I didn't see that it was 8 hours while you were asleep. That is not right. But it may be because its working hard after a flash. Please leave it for a while and it should settle, or install better battery stats app (Free on xda) and see whats keeping the phone awake.
Also check what your cpu is set at and the governor, if its on performance it will be maxing out all the time..

The governor is ondemand and I didn't change the clock of cpu...
I'll install the app and come back with a screenshot, so I think it'll be easier to find some problem

Some screenshots.
The graphs show another problem: it is like the phone just know that lost some battery when I turn on the screen.
For example: if I leave the phone with 95%, it pass the hole night "thinking" it has this value, but when I turn on the screen the battery instantly loses around 15%, this "fast drain" stabilizes when it reaches the "real percentage".
Could it be a hardware problem? The battery itself...
Has already someone noticed something similar?
