Hey guys,
I just rooted my GS2 and am loving it, except for one thing that has seemed to change... battery life.
It is really draining badly with very light usage. For example, it went from 100 to 70 in about 7 hours, and I was only actually using it for maybe 45 minutes in total - the rest was in sleep mode.
Should I use the "Battery Calibration" app from the Market? Will it really help?
Also, my battery stats seem to report the phone as "Awake" and "Screen On" a lot of the time, even when I'm not using it...
What should I do?
I'll post a couple pictures of my battery stats tomorrow so you can better understand what I'm talking about...

100-70 in 7 hours I would say its really good battery considering mine
you can try by finding out the services running in the backgound
You can also try using Juice defender (from market). have this for 2-3 days then check

I use battery calibration everytime I flash a new Rom in order to clean battery stats and fake information from the previous Rom...I'm sure it helps...than maybe you can try Betterbatterystat from the market (I think there is also a thread somewhere in xda forum) to se if you have wakelocks that drains your battery even when on sleepmode...

Stock battery
I have done everything from Autostarts to managing my processes constantly. I played hanging with friends, got on here, and texted.
I posted an updated battery usage. I have lowest brightness, lowest image brightness, 15s timeout, etc.
i would probably switch to conservative governor vs powersave
This isn't typical battery life
I'd advice you to use better battery stats and cpu spy to se what's causing your battery to drain so quickly
Sometimes I notice "back up" in bbs, and this casus my phone to drain within a day
Hanging with friends does consume a lot of battery, but I play it too, and this does not cause that much drainage..
I have ICScrewed and with a heavy usage, my phone usually last for 1.5 ~ 2 days
With moderate call/text and idle, it lasts for 4 days.

Dang that is high! Are you sure about that? :O At medium usage /w unnamed i only get about 18 hours total. It was similar with ICScrewed too
Holy crap. I'll look into better apps. Could UnNamed be the culprit? Or the kernel?
Should I buy a new battery? The life waslike this for the few days I was stock, I think
I average around 17hr, on a good day I'll get 20h. I also recommend better battery stats, great app to see what's keeping your device from going to deep sleep.
Another great app is lbe privacy guard, you can deny certain apps and games some of the permissions they want (disabling GPS on those that really don't need it etc).
I'm on unnamed so that isn't the issue. Might be the kernel, just check the kernel wake clock in better battery stats to check. I'm on entropy's latest dd, while i do feel i got better battery life on the kernel with the latest unnamed ROM I'm not to sure if it's the kernel or something else.

I'd be curious to see your graph. My battery is dead now, but tomorrow I'm going to get on and upload Better Battery Stats to my phone. I would've paid for it on the Market, but I couldn't find it when I searched. I'm curious to see what other people think. I switched all Powersaves to Conservative. Is OnDemand bad for my CPU as it constantly trips from 500MHz to 1.2GHz? Should I consider going to 1GHz?

I have a hard time believing that. I've done everything I can to optimize my phone and reduce wakelocks and battery drain, and I still never get more than 20 hours on a good day, and that's with moderate usage.
How do you define "heavy usage"?

I agree. This is my latest battery cycle of what I consider "moderate" use
What I'd consider light usage (about 10 minutes of voice, between 5-10 minutes of cellular data, 10-15 texts, and about 20 minutes of total screen-on time) I get about 35 hours.
I have managed to almost completely drain my battery in about 4 hours though... Thanks Game Dev Story!

I realized I forgot to turn off data when I'm not using it, but I installed better battery stats and I didn't really see any wake locks. Should I try a different kernel? Any opinions on an efficient one? NOTE: I already got the yellow triangle for using the Odin way, so I'm fine with doing whatever to this phone.
I added my better battery stats shots. I guess today would be called a very light to light day.

I see two very top wake locks have kept your phone from sleeping for an hour..
That is a significant amount.
Also, use cpuspy to see how hard it's been working.
I would try to get rid of those top two wake locks...
Oh crap! I didn't see them until you brought it to my attention. That explains some of the idle drain. I'll look into CPU Spy. You guys have been so helpful!
Your kernel wakelocks had no data, probably due to BBS being a fresh install. A full charge should set a proper reference point.

If something's holding that many log wakelocks, something might be spamming a log somewhere.
I can't find anything to help with those two either. Or would seem that the keyguard might have something to do with text messages, but I can't see anything that would spam the log. Where might I be able to read this log?
Also, I'll post my CPU spy stats toward the end of the night. It's looking like it spends most of its time at 500MHz.

Hi guys,
Is anyone having battery drain issues with their new sgs3's?
With my one it wouldn't last 12 hours without dying. Also if its at 100% it'll drop to 70% overnight while i sleep (6-7 hours) and thats with power saver on, sync off and running juicedefender.
Today I factory reset the phone and only installed flash, whatsapp and dolphin browser. Have wifi on, sync, data, gps and bluetooth off. Havent got pictures of battery stats yet since I only reset it half an hour ago.
So is anyone else experiencing battery drain? if so have you fixed it? and how?
Are there any apps I should be aware of that drain the battery?
I would remove juice defender.
Uninstall lightflow app if you are using it.
Use betterbstterystats to identify any wakelocks. The xda thread of the same name will be able to help with solutions.
Other than that follow general tips on increasing battery life that are found all over xda.
This device is easily capable of much better battery life than you are getting.
Good luck.

No issues at all so far, in my case. In fact this is the first Android phone I've owned that has no battery-related issues
Based on my previous experience what you can try doing is (a) install CPU Spy to see if your phone is entering 'deep sleep' appropriately (b) install BetterBatteryStats to identify offending applications.
Even the 'Battery' section in settings is useful -- just check if any apps are keeping the phone awake for longer than you've actually used them ('Stay Awake' number).
ok well ive installed bad ass battery monitor since its free. Also since I did factory restore i charged it to full and in 1 hour 44 mins it used 7% on idle. Going to charge it to full again and use it normally to see how it is.
Only apps ive installed is XDA, badd ass battery, dolphin browser and whatsapp.
maybe you have samsung widgets etc set to refresh every hour or shorter. Or could be Whatapp

Not too happy with my battery either. Fully charged over night and its down to 89% 1hr 30 later. Is that normal? However, you did mention lightflow earlier though which I have installed - Is that a massive battery drain? My battery stats seem to show display as being the big culprit but I have brightness set to it lowest setting.
Also, can't seem to find battery monitor pro on play?

I'm on Omega V4.0 and with wifi always on, fully charged 3 hours back and when i woke up it's 95% remaining. So about 1.66% loss per hour in sleep mode. With regular usage and installing and testing different roms and backing up etc them i easily get about 8~10 hours. Phone's made in Korea and battery mfg date is 2012.5.6.
Plus tons of widgets on home screens.

Go to my Battery Guide stickied in the Q&A section and see if any of those tips apply. In the 3rd post, there are apps that will help determine what is draining your battery.

first of all thanks for your quick help!
now i did take a pic of the screen and i will do the battery calibration app, but after the instillation of the ROM i did go to the CWR and did wipe battery status but it did noting.
thanks again for your help
Can you give a screen shot like the above but with a little more time on it than 4 minutes? Maybe with a few hours on it. That way we can see a little more info. All that is on that screenshot is the modem initializing and your media scanner.
Also when you wiped Battstat in CWR, that was the same thing as the Battery Calibration app is doing. Just the app is easier in that you don't have to boot into recovery to wipe them.
Do the battery calibration when your phone is charged to 100%. A buddy of mine was having awful battery life, turned out he wiped his battery stats when it was only half charged and then it seemed to charge only half way.
Charged it to 100%, then calibrated and viola.

Perfect. You must have either your GPS or Network Location on all the time. That is what is killing your battery. Do you use Maps/ Navagation a lot? How about apps that track your location like Foursquare/Twitter/G+ or FB (even apps like Angry Birds do this crap). Find the app that is broadcasting and you'll find the leak.
I have the MLB At-Bat app on both my phone and my tablet and on my tablet, I allow it to use my location so I can watch the games. It is a wifi only tablet and I have the wifi policy to cut off when tablet is in stand-by mode. On my phone however, I manually turn it on/off when I want to watch a game, so it never interferes with deepsleep and not broadcasting my location using GPS and battery at the same time. See where I am going with this?
I am betting that you don't get into deepsleep much because of the wakelocks interupting the sequence. Install CPUspy and let it runs for a few hours. After a bit, open it up and I would venture to say that your DS will be minimal.
Let's solve your battery drain first and then we can put on our tin-foil-hats and I'll show you some apps that are tracking you.

i uninstalled a lot of apps after what you wroth me but still no change
i have a felling that all of this is happening because of the devil3 kernel, just after i installed it the battery went low!
Do you have the devil configuration app?
If so, what are your settings?
I run the devil kernel on both of my devices and I average about 28hrs battery life with moderate to heavy use.

That's because battery 'recalibration' (at least these batteries) is voodoo nonsense
It sounds like a process(es) is causing wakelocks which is causing excessive drain when the phone is idling (from what you've described).
Get BetterBatteryStats from Google Play, then read the BBS thread on here (search for it; if you can't find it, you can access it from within the app from memory). That should give you some clues to help you track down what's causing the drain. If you're still stuck, you should be able to post stats/screenshots to the BBS thread & I'm sure people who post there regularly should be able to help you.
I disagree with your statement about battery calibration being nonsense.
Do some research into the battery gauge chip in the S2 dude, resetting it definitely works
You're right though it could definitely be wake locks too

Maybe you are right. ill look into it
You can try GSam Battery Monitor:
https://play.google.com/store/apps/...?t=W251bGwsMSwxLDEsImNvbS5nc2FtbGFicy5iYm0iXQ..
It is easier to find an application that consumes juice in GSam BM than in BBS. BBS is very good but more difficult. I think your problem is beeing made by bad application that sucks energy.
You can also try CPU Spy to get known if your device goes into deep sleep mode.
Try turning of location services. It will help but there must be something else too. Did you try CPU spy which shows how much time your phone is in deep sleep when not in use?
