Depends on the usage of the phone. With normal usage I can expect to full days of battery life from my Note 2

Hi... I get more than 18 hours with my ( I mean really heavy usage )Wifi Calls and occasional gaming...
Try http://forum.xda-developers.com/showthread.php?t=1179809 for a better battery reading and then disable or force stop the battery draining app.

Just show us a screen shot of yourbattery stats and screen on time please. With wifi on and face book chatting sms and Web browsing i got 8h screen in time but Wythenshawe custom rom and kernel. Underclock and undervolt.
With stock from i got 7h screen on time with power save me on

Not really good but it depends on your brightness settings. You put it on max? Just r reduce it and which rom do you use know? Stock rom?

A bit on the low side. Like the suggestions above, try lowering screen brightness. Is this on heavy usage/gaming? If it is, it's actually quite par on the course. But yeah, can be improved.

There no secret of you play you have to undervolt cpu/gpu and underclock. Just put ON the power save mode. There is no lag with

Brightness is at low... n i am using stock rom n wifi on most of the time.. bttry is still under wrrnty so is it ok ..or should i go for replacemnt??

My girlfriends phone lasted for 2 days ang 6 hours on stock rom without any tweaks like SuperCharger. Phone activity is texting, games, browsing using data network and music. So it shows that SGY can go for 48hours. My bad i just forgot to have a SS on it to show it to you.

yea downclock possible but only on stock roms. why? not compatible with scripts and he says he downclocked it to 500 something mhz. but since doesnt have a kernel customed, it was only down to 312. tried it a thousand times. i got a CPU checker. overclock it to 1000mhz still have 832. so downclocking would still fall to default 312mhz. so till now u can do so as the author said but better for stock only. it will crash most of your apps on custom rom (so far i tried it on stock and creeds)

Yes it is possible... Use SetCPU to do that... Unfortunatly it needs Root Access... Gud Luck...
Mine only last for 20 hours at least, but after installing HYBRID rom the duration had increased substantially.
Guys, how long does your fully charged battery last on continuous internet 2g / 3g access?
in my phone, it lasted for about half a day only. how about the others.

Test it with stock ROM and stock kernel.

You should try a different kernel, ROM and/or baseband.
Try clearing your battery stats
Sent from my LT26i using xda premium
I got this other weird problem. I wiped the battery stats, use it till it drop dead, then I charged my phone till it shows 100%. Then i power it down and took out the battery and insert it back again. However, once the phone turned on, it shows only 75%.
I read that this usually happens to extended battery coz the kernel doesnt match with the battery reading or something like that. However, im using stock battery and still this happens to me.
My phone had always have battrry draining problem since i first bought it. Been using it for 4 months and the battery still drain ~10% an hour.
Im using xperia s beta rom v5, doomkernel v19,baseband 56

Try another ROM

Use baseband 64 I think is better. Also try some other kernel.

Battery life on AOKP build5

Hello everyone
I am running AOKP build 5 since this morning. And the battery drains super fast with 6hrs awake including 2h30m of screen on. I would like to know what you guys get on battery to be sure this issue comes from my end, or from the rom.

I've recently had alot of trouble with roms and battery after leaving AOKP Build 4 to try a CM10 Nightly and then going to AOKP Build 5 since it came out that night. I get around 8-10 hours of battery life and it could be better. I leave for school at around 6:40 AM and need my phone to work til around 10:30 PM. So its not just you (unless we both are missing something )
My battery life is awesome. Using the UVLE1 radio with all stock CPU settings, 100% brightness, and no data disabling.

Try calibrating your battery. Did you wait 10-30 when you flashed the rom ?
The issue is gone after the second cycle. Today i got 12hours with 3:30 screen on and still had 8% left. Maybe the rom need time to settle down.

Battery life is horrid, am I missing something?

I'm running the stable cm 10.0 build with lean kernel. Brightness at half. From these images I'm barely achieving 9 hours with less than 3 hours of screen on time. I'm confused, I thought this rom/kernel combo was supposed to produce great battery life? Can someone help me. Thanks.

Calibrate battery if that's a new ROM give it a few days. My phone sucks battery no matter what kernel or battery. Just ordered an extended one a few hours ago. Hopefully, by the time i move to the fifth generation galaxy device, this retard battery issue will be solved
Sent from my SGH-T999 using xda app-developers app
If your are planning to get a battery extension i suggest get the 3000 mAh of samsung this Jan 5th that would increase your battery life up to 49% (i read that here in XDA idk where is it but its true ) and also try TRINITY kernel would be awsome if you done like it you could revert back to lean - its only a suggestion
EDIT:
Is this your 1st battery cycle in this rom? usually that is normal the following charging cycle would be stable from what you expect
Been using this for 2-3 weeks now I was hoping it would improve but I
it hasn't. I'll give trinity kernel a try, thanks.

If you need the extended and a case, look for the seidio active extended. I did about 5 hours of research to ensure i get what fits me best.

Calibrating is useless, its a bunch of snake oil. So don't even bother with that.
Sounds like you need to check for a bad app preventing your phone from sleeping, otherwise flash to stock and re flash.

I went with the qcell extended battery, currently running the Aeonfluxx v6 rom. On heavy use days I usually have 50% battery left. My stock battery didnt last 6 hrs before. The sg3 is my second Samsung phone, and both sucked with battery life.
Try a touchwiz rom bro... might save you some battery. also less widgets, check what apps are running during sleep mode and my favorite

Heya,
I have had this happen once before, the battery percentage went up a little bit after watching a movie when it went back to less intensive tasks, it only did it once or twice so it should go away
