Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.
4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?
Turn Data usage off :/ i think Fb or some app is using your 4g

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium
That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App
Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.
So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.
Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?
Sent from my Nexus S 4G using xda premium
The battery was 88% at 10PM and at 6AM it was same 88%. I enabled battery saving mode and flight mode. Wifi was off. Auto Killer set on when the screen is off and Droidwall enabled for unwanted apps. I think this is good performance of Battery. by the eay, the binary count is 0 (inspite of flashing 6 custom roms). Thanks to Triangle away. The device N7000, Kingdoird V4 and speedmod #3.3.
You may lose this good after install some new app so be careful.
can you upload a screen shoot of your battery stat. without using network and closed many apps then what is the purpose of buying it.did you turned on display anytime.

Why did U even buy a phone?
Sent from my GT-N7000 using xda premium
There are times when you can't charge a phone.
Personally - I NEED a phone that can last 24 hours without dying. The closer we can get to that the better.
Draining always depends on usage.But galaxy Note is a good one bro. By average use its battery stands for a whole day.
Thank me if u like. B-).

I can't believe just how good this battery is on this phone. Last night I couldn't be bothered putting it on charge, I was too tired. This is not light usage, I've been texting a lot and been on the phone for about 30 minutes, I just made sure I closed applications I didn't need and cleared the RAM a few times. I could probably get longer than this without Wi-Fi and Mobile Data!

here are the following things that will improve battery life
1. mobile data and wifi all off. turn it on only when you use it.
2. dark wallpaper background.
3. turn on powersaving. < let's take his word for it,he said he doesn't use power-saving mode. imagine if he'd use it, he says.
4. 15sec screen timeout.
5. sync off
6. freeze non-essential apps that are running in background.
7. silent mode all the time.
8. brightness set to the really lowest setting that you are comfortable with.
9. turn off all motion
10. turn off s-voice and voice command for apps
11. disable vibrate
12. disable smart stay. this runs @ 1.4ghz everytime it checks.
13 fast dormancy on/off depending on your network
other things you can also do and like the rest can't be seen with screenshot
both of these possible using custom kernels. < don't worry he says he's using stock.
14. underclock and undervolt cpu and gpu. may not be that much but if you have the impulse to brag and crush us with your knowledge then every percent of battery saved is important no matter how minute.
15. force single core
16. sgs3 that has snapdragon instead of intl version. < don't worry he said he's using intl version.
AND LAST BUT NOT THE LEAST:
17. DISABLE AIRPLANE MODE WHEN TAKING SCREENSHOT TO BRAG AND CRUSH US WITH HIS KNOWLEDGE, SO THAT NOBODY WILL NOTICE YOU REALLY ARE USING AIRPLANE MODE ALL THE TIME AND ONLY TURN IT OFF WHEN YOU WANT TO CALL OR TEXT SOMEONE OR RECEIVE CALL AND TEXT FROM EVERYONE.
YOU CAN ALL SEE IT FROM HIS SCREENSHOT MOBILE NETWORK SIGNAL MORE THAN HALF OF IT IS BLANK MEANING NO SIGNAL.
EVEN ON THE LAST PART OF THE MOBILE NETWORK SIGNAL WHERE IT'S STILL BLANK MEANING HE JUST INDEED JUST TURNED OFF AIRPLANE MODE TO TAKE THE SCREENSHOT TO HIDE WHAT HE'S REALLY DOING TO CONFUSE OTHERS.
HE DID MENTION ON HIS TIP THE AIRPLANE MODE, BUT HIS BEING MUM ABOUT AIRPLANE MODE WHEN ASKED BY PEOPLE HOW HE DOES HIS "CRUSHING KNOWLEDGE" OF BATTERY LIFE AND NOT MENTIONING ON ALL HIS POSTS BRAGGING HIS BATTERY LIFE THAT HE'S ALWAYS ON AIRPLANE MODE AND THE FACT HE TURNED OFF AIRPLANE MODE DURING THE SCREENSHOT JUST SHOWS HE'S AN ATTENTION WHORL.

http://s8.postimage.org/e8asy2cn9/CRUSHYOUWITHMYKNOWLEDGE.jpg
normal people use phones like that.yeah right, if they do mobile network signal should be green most of the time not full of blanks like that wherein we are crushed by his knowledge.
people buy phones to use them as phones TO HAVE MOBILE NETWORK SIGNAL so that they can be called and messaged also, they don't buy phones so they can brag about on screen time and calling it crushing them with your knowledge at the same time.
if you all want real battery life using a phone as a phone meaning mobile network signal is always green thus no airplane mode,
the real honest results for stock rom international s3 no underclock/undervolt no power-saving
basing on many honest posters feedback is about:
1 day + 1to5hrs on battery
with
on screen time of 4hours30mins to 5hours
with at least 10% battery remaining.
pushing it to 5% battery remaining or even to the point you can already see exclamation point on the battery icon you could reach 6hours+
blah blah blah no Air plane mode either. blah blah blah
see?
yeah right!no airplane mode my az. your screenshot having no mobile network signal almost 100% of the time shows otherwise.
if you didn't use airplane mode in your school where you have bad reception, the phone constantly trying to find network signal will drain its battery more we know it won't last.

come on guys let's just give him a break
1. a thread about battery life showed up, he was the first respondent.
2. he was first respondent because he was very very eager to "crush with his knowledge" any op with battery life topic and claim another victory for him.
3. he sacrificed 4 days and 16hours of his life so he can "crush us all with his knowledge"
4. screen on time is 15%. so 4days16hours or 112 hours, 15percent of that is 16hours. so you buy a phone that you only use not even for a day in a span of 4 days.
omfg we are so crushed by that kind of knowledge.we're not worthy.
where is that phone that i don't use and not scared to have scratches cos i throw it around and not use it for days?
oh found it. under my bed.
my samsung galaxy pro.
be CRUSHED with my amazing KNOWLEDGE of battery already 2days and battery still at 85-90% range.
don't worry, on the 4th day i'll use it for 16hours.
that's how you use a phone,use it only for 16hours in 4 days. teehee

many may not understand what it is with that CRUSH and KNOWLEDGE thingie.

Hi guys,
Is anyone else get terrible battery life with 3g and data on even on standby? I believe the phone function drains the battery and it lasts only 2 days or so on standby. I constantly have the tab on flight mode with wifi enabled and battery is much improved to about 1 week standby. Anyone else? I am on stock 4.0.4.
Thanks

Hi Iong. We are talking about a tablet here, not a phone. Tablets should have 1 week standby at least. The battery drain with 3g and phone on is unacceptable. I think the reason is the connection to phone signal which is constant.
Mate 1 day pr 2 day standby is a lot, given the fact you install many program and it constantly connect to tinternet to check for updates notifs etx. You dont have 1 week standby whatsover, forget it. Big tablet big baterry big screen. Ot all goes scaling together

So 'l2_hsic' and 'batt_work wake lock' are the 2 processes keeping my table awake for 5 hours in total since yesterday. Any idea of what these do?
Thanks

most likely is that one or more of your apps is causing the problem. try a reset and see if the problem goes away. if it does, install apps one by and and check which one is the problem
Use juice defender ultimate in tablet mode. I can go several days idle time and lose almost no battery.

Hello folks.
I'm currently on Aokp 4.2.2 unofficial with Francos r90 Kernel, bootloader and Radio are both updated. I'm suffering from massive battery draining. I guess something isnt letting my CPU sleep properly, as i always get messages like "100% awake while screen off" from battery stats plus. I'm just getting up to 2 hours screen on time, and battery is falling by about ~7% / hour With normal usage (whatsapp, News, xda) and like 15 Minuten screen on time in that hour. Also, see the attached Images. I sometimes have wakelocks by audioOut_2 and as you can See, maps is using more battery than the Display itself.
On an additional Note, GPS is always off, im using Taster to locate, but with cell near only.
Would be very Kind to help me out of this issues, thank you a bunch!

Turn off Location Services for a little bit to see if that helps.
You should try a program like autostarts, and don't allow things to run unless explicitly started by yourself. This way it'll help identify if there is an misbehaving program.
I saw you were using franco r90 which could be an issue. Try going back to the last stable
I think you will like this application.
https://play.google.com/store/apps/...GwsMSwxLDMsImNvbS5vYXNpc2ZlbmcuZ3JlZW5pZnkiXQ..
This simple application will make your annoying applications to go to sleep. Therefore your phone can finally go to sleep like it should when it's not in use. I see that Google maps seems to be the culprit in your battery drain. You can use titanium backup and delete it and install it back again from the play store. After that you can use the application that I've given you and force it to go tot sleep.
Here's the forum for the application:

Coming from the iphone 4, good battery life is the most important thing i miss. I need a rock solid reliable phone or else would have started to mess around a read about Kernels to see how they may help with better battery life. My iPhone would last me 3-4 days of general use. To me General use is very light use..! With nexus it lasts max 1-2 days but more importantly i need to be concious what the battery level is. With th eiphone i never really bothered as i knoew i would get at least 2 days if not more.
