I'm having awful battery life with my phone and I have no idea what is causing it. Yesterday I clocked it at 8 hours from full charge to about 10%. I barely used the phone. Very light use.
I already re-flashed several times including clean flashes. I had it in CM9 and now I'm on CM10 but it's still the same. I even tried replacing the battery but, as far as I can tell, I'm getting the same discharge rate. I tried charging it to full charge and then deplete it completely, but it doesn't seem to do any good.
Looking at the battery stats I can't see anything unusual. Screen and Cell standby are usually at the top of the list, with anything below it at pretty low percentages (lower then 10%).
Can this be a hardware issue? Appreciate any help!
I'm running cm10 with note 2 radio and CPU sleeper. I average 15-17hrs on battery .without CPU sleeper I average 10hrs.

Thanks for the responses. Unfortunately, CPU Sleeper and Juice Defender are both workarounds rather then solutions.
It seems like there's a fundamental issue here which I'm more interested to solve.

Get better battery stats and CPU spy. BBS can tell you if something is preventing your phone from sleeping, and CPU spy can show CPU usage over time, by clock speed.

Thanks for the suggestions.
I checked CPU Spy this morning to see how the CPU acted during the night and it seems to be ok. 61% @ Deep Sleep, 34% @ 384MHz and 2% @ 1512MHz. As far as I know this seems normal, but the battery drained from about 93% to about 72% during the night. I only leave WiFi on. Is this a normal drain rate?
It seems like BBS still needs more time before it can generate a report.

+2. It would wake my phone 200 times a day on aggressive. Not to mention occasional problems getting data to turn on when I woke phone. Battery seemed better without it.
Try Gsam. To see what apps are waking phone and using battery power. Maybe its the same as BBS...not sure..never tried BBS.
Remember...its not about total battery time...its more about screen on time. I get anywhere from 2 to 3 1/2 hours screen time. And gsam has me at 22 hours average battery life.
I know you said you depleted and recharged, but did you calibrate? That worked for me a while back, now I do it every time I flash a new from which is like once or twice a week.

61% deep sleep is not good, or normal. I would look at BBS and focus on partial wakelocks to determine what is keeping your device awake.

I'm kinda having a hard time interpreting BBS. I'd appreciate if you could take a look at the screenshots and maybe see if you notice anything suspicious.
Also, I checked the CPU States in BBS and it is listing better results. 84% @ DeepSleep, 13% @ 384MHz and 1.8% @ 1.51Ghz.
So I just had a major drain. About 40% battery gone after about 3.5 hours of hardly any use.
In Parital Wakelocks, BBS showed NetworkLoacationLocator at the top of the list. But the run time for that is listed for only 4.5 minutes. In the Kernel Wakelock I got "wlan_rx_wake" at the top of the list with a running time of 1h 11m. This seems suspicious to me. Any ideas what the hell is this and how to solve it?

So I just looked at my battery usage and notices that my phone has been "awake" for such a long time. I know I haven't used it much at all today. Anybody have an idea why this is?
I would upload the screenshot, but its telling me that the file has the wrong extension. ???

I have a huge battery drain (about 60%) by OS Android proccess even in the standby mode. I don't know what to do with this ****. From 100% to 0% it takes about 6 hours my phone dies in standby mode (with CM9 rom), with stock rom my phone lives in standby mode about 2-3 days.
Sounds like you have a rouge app(s). Download Better Battery Stats and CPU Spy. Read their respective threads to understand how to use them. There are threads where people will help you interpret the logs these provide.

I agree with dnorthington. I had the same then I realized that drawfree was draining my battery in a matter of hours...
Android OS only reports such high values in ICS because it includes screen on time.

Did you download better battery stats and CPU spy? Look in the ATT Galaxy S II thread. There's a pretty good known battery drain thread. My idle drain is less than 2% part hour. My deep sleep is over 95% when idle. Has to be a rogue app.

I charged mine and let it sit for 7 hours. With wifi set to always on, I get 11% drain overall, 92% deep sleep and 6% at 192.

I don't see a thread like this for the T-mobile variant so I figured we can have our own. It would be nice if you included the following with your posts:
screenshots including on screen time, information about your rom, kernel, etc. and estimated talk, text, browsing, and gaming time, and what brightness you had your screen on (auto, full, etc.). If you use something like SetCpu with profiles list your profiles and settings here too.
I'll start:
This is only my second cycle charge on this device. I only got it 2 days ago now which means it still has room for improvement
My sig has my rom info and I basically did a lot of twitter browsing, about 100 texts a few short minute phone calls including an hour long call when it was at around 10%, a lot of XDA reading, and no gaming today.
I have the device overclocked to 1.89ghz with this kernel with min set at 384mhz ondemand governor. I have a profile that clocks down to 1.5ghz at 50% battery life and another that clocks down to 1ghz at less than 10%.
I've never had a device give me 4h on screen time especially with the abuse I give this device. I can't wait to try out other kernels and roms to see these numbers rise.
I could get a day and a half with no tweaking and low usage, on an average day I'm getting ~15 hours before it starts whining about the battery
Yeah but what's your on screen time?

Right?! That's what it comes down to. It doesn't matter if your battery life is amazing if the reason why is because you barely if ever use your phone...
I'll post tonight just got my new anker battery.

Considering your screen was barely on during those 18 hours I can see you didn't use the device much. This is barely average.

I could make it 24 hours easily with light usage. With moderate to heavy usage, probably around 20 hours. It really depends on how long the screen is on though. This phone has amazing battery life. My HTC Amaze probably only lasted half as long.

I agree, best battery life I have had out of all of my previous smartphones. I am still testing roms and kernel combinations to figure out what works best for how I use my device. I'm in the middle of testing FSG3 rom with trinity kernel. Will post up battery usage within the next 2 days to compare to my previous Stock rom with Adama 003 kernel battery life.
My Screen
Pretty Good so far, Stock Rom - Rooted - Still 40% left.
This is with the fsg3 rom and trinity kernel. First and only cycle so far. Brightness 100% wifi on most of the time, and data and gps always on. Played music for about half an hour and browsed xda for half an hour.
Edit: screen on time was just over 4 hours deleted the ss by accident.
Will post up the 2nd cycle when it's done.

New screen shots after a few cycles. Again fsg3 rom with trinity alpha 36 kernel. Brightness 100% wifi on most of the time, and and auto sync also on.
Look at screen time on not just total battery time. This is what determines good battery life not letting your device sleep on your desk for 2 days and saying you get amazing battery life.

Cause to me it seems a little too fast. I took this screen shot right after arriving at work a couple days ago. All I did with the phone was unplug from the charger and drive to work.
Then today I unplugged it again and in like 5 minutes of me searching something in Chrome it drained 3 percent.
I'm at 85% right now and it's been just a little over an hour.
Is this normal?

Are you running stock TW ROM? Also use betterbatterystats, cpu spy, and gsam battery monitor. To see if you can track down if there's something keeping your phone awake/running when it shouldn't. Also cpu spy tells you if your phone is actually going to sleep when you turn the screen off or if there's something running

I don't know what is causing this massive battery drain overnight. It went from 99% to 29% in a matter of 7 hours overnight. Here's some screen shots from better battery stats and the android battery stats.
I'm not really sure how to solve this problem with the fast battery drain.
Any insight would be greatly appreciated.

Hello All,
I just received the DMA6 update from Samsung... I know this update is new but it would be good if all of you can post your comments on the battery drain after this update.. Feel free to post screenshots of the battery..

Since flashing my battery life and deep sleep battery life is greatly improved. Very pleased with this update.
Thanks for your reply.. I just installed the update and am a bit skeptical and feel as if the battery is draining faster when the screen is on.. Might be that when the phone is in idle or deep idle the battery would be dropping less significantly.. let us wait for other users to post their comments... hope fr the best...

I had no batt issues since upgrading to 4.1.2
with this new update battery life seems better. Left my phone at 10% before i slept and woke up to it still at 10% so deep sleep is really good
Thanks Paulito.. As i said i am suspecting that deep sleep is good now... but do you notice a faster drain when screen is on.. Do let us know.. I will also keep an eye on the battery stats for the coming weeks and keep all posted.. :beer:

Guys, install Batter Monitor Widget and do a real test to see what your standby and screen on consumption is in %/hour. We need real numbers, not anecdotes.
With DLL7 I get between 0.6 and 2%/hour drain in standby. Screen on averages 10-18%/hour. Gaming is usually 30%/hour. Wifi on, brightness on auto, location on, Facebook , google plus, tapatalk and 2 gmail accounts syncing with notifications.
I'd love to see what this new firmware gets under those conditions .
I can't wait until it's available for my variant. On DLL3 my battery was terrible! I went back to 4.1.1 where I can easily go all day with 70% of my battery remaining.
I shall install the battery monitor widget and will upload my findings in a couple of days..

Nothing required to enable it,
it should go to deep sleep, if it doesn't go to deep sleep then you have to find out which process stoping it to do so.
