I'm loosing my mind! Almost every ROM/Kernel i've tried so far is seeing some serious battery drain due to the Android OS service @ 50%+.
Is this normal?!?! I don't use my phone much but I keep having to charge it twice daily. I've also calibrated the battery using the unlimited amount of guides and apps, but no go.
So far i'm trying all the AOKP ROMs and they all do the same thing, even with different kernels, different CPU scaling governor like ondemand, smartassv2 and hydra.
I think i'm going crazy,

Your phone isnt going into deep sleep. You see it on the blue line under the discharging graph.
Are you using live wallpaper?
Sent from my GT-I9100 using Tapatalk 2
I bought batterystats and just not sure how to read it. I've created a dump file from it and attached here.
I'm not using any live wallpapers, and have downloaded very few programs such as doubletwist, chrome beta, battery calibration, dropbox, fasterfix, go launcher, team viewer and titanium backup. But even without those apps I was still seeing battery drain.
Delete all contents on usb storage except for music and videos.Wipe cache and dalvik.Restart phone.Let it settle for a couple of minutes.Should be ok.
I did that and now I wait. I'll report back tomorrow hopefully with good news.
I noticed that with CPU Spy shows that one of the Unused CPU states is Deep Sleep before so I'll check that out after this.

You have got same crazy apps running in the background. If your not hitting deep sleep you have a serious problem. Another thing to clear is media storage .

After running the kernel cleaner script, wiping data/cache/dalvik etc, I installed Wanam's newest ROM JHLP9, and now no more Android OS keeping the phone up from deep sleep.
It seems to me that all of the AOKP ROMs have some serious battery drain issues, or just bad luck.

I have a Samsung Vibrant and it's running CM7 7.1.0.1 with the following kernel
2.6.35.12-gdf10700
My problem is that the process "cell standby" has been killing my battery for the past few weeks or so. I'm looking for a new kernel that won't drain my battery so quickly.
Thanks in advance.
Im also noticing cell standby drains my battery pretty bad. Even with Ultimate defender
Have you tried Bali-CM, 99Problemz, or Streamline?
I installed Bali, but I'm not sure how to configure Voodoo Image.
Have you tried rebooting your phone after taking it off the charger? That has fixed my drain issues and lets the phone go into deep sleep properly.

For me the stock CM7 kernel works best. I am on the latest nightly.

What are u doing to get this kind of bat use? Is it just the latest build? What modem are you running?
Including 8 - 9hrs sleep (periodically waking to fiddle with World of War), I get 24hrs or slightly more on a single charge with MIUI (same backbone as CM7). I simply freeze or uninstall any apps that use battery that I don't need, such as Gallery, Music, File Explorer, etc. I'm also using an Epic 4G Touch 1800mah battery ($20 from Mobilecityonline) and am using the Glitch ML kernel for some ridiculous undervolting (in my signature).

Can anyone confirm that the Epic 4G Touch 1800mah battery works on the Vibrant?

Yes it works
as the title says. I am looking for ways to get my battery to perform like it did before.
I was using villain rom with SPEEDMOD kernel.and I had very good battery life. one night I noticed my battery getting really really hot while charging. then the battery life went down hill. I tried wiping battery stats, removed battery for 5min after full charge, changed to cm based rom(it was even worse). i upgraded my modem to KI4. Now I am in villain rom with SPEEDMOD, (17) kernel and the battery life is still ****.
any suggestions####. yes I could blame Android os bug. its a 2.3.5 rom and I turned off all the sync as well I have absolutely no idea how to solve this issue.

it is with minimal use. theme is not the culprit as I have tested without theme and got a similar results.

I did not want to change the ROM but I gave 'HyperDroid-Androidmeda' a try. to my surprise the battery drain was gone. then i installed ics theme 'the battery was still good'. then I set up google account and restored K9 mail via titanium backup. THEN AGAIN the BATTERY started to deain heavily.i uninstalled K9,but the battery drain had not gone, uninstalled titanium backup no LUCK. still investigating......but i know i am close
The batteries used in the SGS2 do not need (and therefor not offer) calibration.
Your problem is something else and there is about a million threads about how find'n'fix the issue.
Out of the blue, I'd blame some app you're running.

I am aware of all the other threads. I've faced battery life problems before as well but it was usually resolved by flashing a different kernel or rom. you may be right about the rouge application.

can anybody help me make sense of what is killing my battery. btw I did ude the audio recording software for an hour and also the circuits app but they are not the culprit. main problem is that the phone does not go to sleep.... and battery drains rapidly.
i for first 50% of charge i was on speed mod kernel ... there was battery drain. and then i flased the rom again, the battery life got worse.
Sent from my GT-I9100 using XDA App
UPDATE....wifi was preventing my phone from going to sleep(still dont know what the real cause is)..... AFTER several ROMS and a DEAD SD card... my problem seem to be gone...for now at least. i basically flashed official firmware and flashed speedmod for root and clockwork mod. then flashed checkROM with speedmod again. fingers crossed the problem is gone.
Howdy all..
I have a couple of questions about battery usage relating to screen power consumption.
First some background on the.phone
Aussie i9100t
Cm7.1 with its base kernel (wolverine)
Stock radio kf2
Now, if j sit down and read tapatalk or Facebook for 15 minutes ill burn 5% battery (even with the new Samsung 2000mah battery I just bought)
I have the brightness set to manual and as low as it will go, it actually seems way too. Right for minimum settings to be honest.
Just wondering if anyone has some suggestions on where too look for issues
Edit, just a note, I've had 2x i9100's prior to this model and I'm pretty positive they weren't this bad
Cheers
Kyle
Try a different radio, if your browsing on 3g....if on wifi try a different kernel like siyah
Thanks for the reply.
I gave siyah a go yesterday for 12 hours but found a similar result with the stock battery.
Dunno hey, just find it quite strange that the last 2 sgs2s I've had were not like this..
Couple of screenshots..

Thanks for that mate, do you find lag when scrolling with siyah? I got it a bit, maybe selected the wrong governor or something ...

Hello guys,
I flash twice my Xperia U to ICS and I done it well. At frist one, i made without reset factory and the second one with reset factory.
In both cases I got the same problem.
The ICS is draining battery life hard, even in stand by. No mater what, It consumes about 25% for each 4h. Using hard or using nothing.
I instaled GSam Battery Manager and it says its Kernel and Android OS.

When I used gingerbread, my battery lasted almost 2 days easily.
Android version 2.3.7. It lasted 41h and still have 19%.
Please, someone can help? I tried everything i know. No matter if data or wifi is turned on or off, it will consume lot of battery. I tested.
It seens impossible to reach 24h in this situation.
Same here
New ICS su.....
I'd uninstall the task killer and battery defender to begin with, they will drain your battery like crazy.

Try using titanium backup
Freeze all the applications and services which you are not using..
If u do a thorough search in the forumyou wil find the list of services which are safe to freeze
Set maximum cpu usage to 200mhz when screen is off..

Yes definitely u need root
I'm not using my U yet, got a sim in it, but still using my old phone for now. I'm running ICS and am getting 12-15 hours battery with less than 10 minutes use. The rest of the time it's in standby, there's a pretty bad battery bug, I've not figured out what causes it. On GB I was getting 15hours medium use (~3 hours) and would still have 40% battery left. Battery info is showing it as awake the whole time it's on standby.
My phone`s original battery lasts for one day in normal use. I bought a 2680mAh battery in eBay and now I can use my phone all day long without any problem.
Are others having this? i mean i go through a full battery about twice a day.... I cant figure out what is draining it so bad. i have used WLD, greenify, and bootmanager to try to figure it out..... None of my apps are ever on the battery list, and screen is around 50% usually with android system and android OS always being up the list. I always thought it was my bad signal strength at work but i had two weeks off and my phone NEVER lasted even close to a day.
I have factory reset once but loaded my same apps backup.
I heard someone else mention that the sprint has this weird battery drain that is explainable and was wondering if others see that also.
I am on the search for a 6000+ mah battery i know it will have a replacement back plate but i don't want the whole case thing like the 9000 zero lemon.
Sounds like kernel wakelock
As of the last two days i have also been experiencing much faster battery drain. Have had the phone since launch and never had this problem.
I do not use the device in excess. Very few if any phone calls per day, some texting and gmail, occasional skim of xda, huffpo, phandroid apps and very light Twitter use if bored and not near the computer.
Battery has dipped 5% since writing this post...that's all of 1-2 minutes in use.

That's not normal for a Sprint LG G3. A couple of questions:
Have you looked at the battery stats page to see what app(s) are using the most battery? I'd suggest taking a screen shot of that page and posting it here.
Have you tried rebooting the phone? If there's an app or process running out of control that will often clear it up.
Are you rooted? If so, install better battery stats so we can get a better look at what's eating the battery.
Finally, you might want to take a look at this thread: http://forums.androidcentral.com/sa...android-system-eating-your-battery-check.html
While it's unlikely you have the same problem I did, the tools and techniques I used to debug it might be useful for you.
Gonna wait for some custom roms to see if the problem just goes away.

Dude the battery app should show you what is causing it. Something has gone rouge!!! I just had my weather app running in the background using GPS for 5 hours, yeah my battery went way down. Freeze some BS apps. I routinely get 30 hrs plus on a single charge. Not the phone itself something you are using is causingi it.
As requested, my craptastic battery info. Brightness was 83.
