Different battery discharge rate. Any ideas?

Hi guys. I'm running on CheckROM revoHD4 and while sometimes I lose 10% of battery overnight today I dropped 30% in 3.5 hours doing absolutely nothing with screen off and not a huge ammount of apps running on the background. And its not the first time I notice inconsistent discharge. When I installed this ROM battery would last for 20h/3h screen/3h voicecalls. now sometimed it doesn't even last half of that. Any ideas?
You should check the battery info via Settings > About Phone > Battery Stats to see if you find a proccess that is huging the battery.
Also you could download Better Battery Stats from the Market and find which proccess are the ones doing the more Wake Locks and how much time they have done it. You could find for example an app thats been doing that for hours and that could be the cause of the battery drain.

Battery indicator inconsistancy

Hi
Its been 2months i bought galaxy s2 and 1 thing i dint like is the battery life. Im getting only 5hours of battery life with internet on. Ive installed the battery life saver apk Juice Defender and still the battery life is very less. Please suggest me something.
Also i read a post in the same website saying that the android 2.3.3 has this OS problem. The form told me to shutdown the phone and remove the battery for 5mins Nd use again. But when i shutdown the phone the battery was 45% and when i switched on again,the battery indicator was 15%. Then after sometime, it increased to 27% without charging and then reduced normally. Please help me with this, what might be the reason for battery life being inconsistant and what can be the solution

you might have an application that keeps your phone awake. what i mean is by having your screen off there are applications in the background still running. So my best advice is Juice Defender does not do anything and infact it drains more battery than saving it.

probably yes... Bcos when in idle, sometimes the display suddenly turns on and again after sometime. Is it possible that the phone is infected with virus?

No you not have a virus but probably you either need to update your firmware or change kernels if you are rooted...

I believe you have rooted your phone, if not follow chainfire thread ( http://forum.xda-developers.com/showthread.php?t=1103399) for rooting the phone.After rooting goto CWM recovery > Advanced > Wipe Battery Stats. This should give you a clean slate on the issue of battery inconsistency.
As for battery drain, remove all battery saving apps like JD, they infact consume more battery. Install Betterbatterystas apps from market ( paid app) or the free version available on XDA, and check for the partial wakelocks / kernal wakelocks to get to know what apps are killing your battery.

battery drain while sleeping

last 3 nights I noticed huge battery drain, about 1% per hour, anybody knows where is the problem?
my tab runs stock ICS rom and stock kernel
thanks for help
after some diagnostics I found that GoogleServicesFramework is battery drainer (not sure, it has most wakelocks in betterbatterystats - about 50 in 5 hours and its awake time is about 1:30)
Try the OsiMood ROM http://forum.xda-developers.com/showthread.php?t=1677281. I previously was very disappointed in battery life, but after switching to OsiMood battery life is much much better - especially in sleep mode. Overnight unplugged it drops only 1-2%.
I downloaded autostarts and disabled startup of GSF on every event and left only Application Installed event (if disabled, market wont download any app)...seems that battery life is back to normal...99% at the morning (no keep awake time in battery stats) so it is fixed without changing rom , I did this procedure also on my phone and its battery drain during night is greatly reduced

[Q] battery keep draining lately

Hi guys
I m experiencing battery drain lately
I have tried several different rom but all are the same.
Is there any reason why i m having this problem.
Is there any rom that u guys suggest me to use just to ensure that the battery drain is not because of my battery.
I think the battery might not be the reason for the heavy battery drain because my phone is only 2 months and the battery is well taken cared.
Thanks guys.
Have you tried the app "BetterBatteryStats" to verify wakelocks or points of drain?
Without some specific info, there's not much we can do to help I guess.
I only have a huge drain with the stock firmware from Samsung. I'm running CM10 now and that's not giving me any drain issues. Put the phone on charge just now after 38 hours.

I9100 battery voltage inaccurate/fluctuating. Tried common fixes. Help?

Good day,
I have a I9100 w/ ResurrectionRemix V3.1.3 and Siyah-Dorimanx Kernel V7.34 on Android 4.2.1. I have been using the rom for a few months already but over the last 2 weeks, there has been severe idle battery drain. 11-15%/hr on idle, more if I actually used the phone.
I have tried calibrating my battery (full charge, drain till 0% and re charge). Also tried resetting fuel gauge chip using STweaks. One thing I noticed though, is that when I go to Testing page (dialler > *#*#4636#*#*), the battery voltage fluctuates. After fully charging my phone and turning it on, it states about 3900mv instead of close to 4200mv. Then it continues to be erratic, for example from 3800 to 3960 to 3870 etc. Is this the cause of my severe battery drain and how do I fix this?
Currently battery is at 79% but 3853mv.

Dude,Resurrection Remix is an old ROM,updated last year.Try to find a newer one,like JellyBam 7.8.0.It Android 4.2.2.Also,update Kernel to DorimanX 9.21.These are the latest ones.I'm running these too,and my battery drain is only 6-7 %/hour.
Battery is on the way out. New battery. Losing capacity is a sign of a dying battery.
I have tried 3 different ROMs and 2 batteries. Using Jellybam 7.80 now. All have the same issue. None of them have had better battery life. For example, I can have 70% deep sleep and a discharge rate of 15%/hr. Not long ago I was having 3%/hr at 70% deep sleep. I only use whatsapp mostly. No social networking apps due to their frequent updating.
This leads me to think that it is more likely a hardware fault. Does a faulty charging port PCB result in this problem?
I will post the BetterBatteryStats page of my current charge after 5hrs of idle soon.
