I'm very concern with my battery performance due to i've read there are people that the battery reach more than 1-2 days, it's true? because my battery only reach 15 hours with a regular operation.
Same mate, depends on what you call normal usage tho, and what you got on the phone. If i dont use it for anything but txts it will last 2 days, otherwise no chance. Use atk pro and kill all non essentials at screen off and cpu master set to powersave to give you bout 25% longer run time.

The rom Im using is rendeiro Cyanogen 6.1.3 V1, camera fix.
When I said that my operation with the phone is normal, because it is. Let see.
20 minutes on voice.
Email sync always on
Xda app many times at day
30 minutes in the web
Twitter sync each 30 minutes
2 or 3 facebook uses at day
And watch a few small videos

I do everything u do except for the facebook sync and twitter sync. Thats probably doing that to ur battery. My battery last probaby for two days but i drain it every night to really low then charge it over night. Try turning off facebook and twitter sync and see what happens for a day

I charge every night, but while in tours, I make sure, I keep my data traffic / wifi / GPS turned off while phone is on standby to extend the battery life.. That helps to push it on for around 2 days at max..
While in roaming, the Network signal strengths also eats a lot of battery, some one told me to use 2G network only, dont know how effective is that..
My phone goes for about one day but i am a heavy user. Youtube browsing using messneger on phone , texting with girlfriwnd . etc i dont mind though ots plugged in each time i go to bed. So when i wake up i have a fully charged phone again to repeat my daily usage

Ok so im quite new to android so im not 100% on the ins and outs on how what uses what battery and when.
Im running skyrom v9 and my battery was crap. To be honest its never been good. So i tried speedmod kernel and still got the same results.
Now iv disabled lockscreen widget and seems my battery is much better so iv put it down to that been the killer.
Iv read some people are using this app with no issues. My friend tried it with the same rom and kernel as me and it was fine.
Question is are these phones like performance independent? Like will each device act and behave differently to different thing or shud one sgs2 be the same as another sgs2 that is set up the same?
Long winded but i got there

They're mass produced, they should be exactly the same. There may be really really slight performance differences. And tiny differences in screen quality. But this may depend on the batch.
What would be the case most likely would be the fact that you have a faulty battery. But it seems you were able to fix most of your problems by getting rid of an app.
There's a lot of things influencing battery life, dude! Every little thing you do and use can get the juice sucked dry in a couple of hours.
I thought as much. Just seemed odd. And although getting rid of that app seemed to work, its now gone back to its useual gonna die soon self. Gonna try another battery i think.

In a way they are all different .
Different users with different apps and settings plus a different and varied level of user intelligence . That means phone A can be poor for user ZZ but give it to user YY and its working well .

Well only thing i have left to try is battery. Im just waiting for my other to charge then i will swap and test it. Best i have had my battery is loosing 10% an hour. Which imo is a bad crack.
When i go to my battery stats it says cirtain apps are using x%. Some of the apps iv never ran. And some like maps for example is using battery. I stop the maps app and still its using battery. Why?

A good test is to stick it in flight mode and shut down as many apps as you possibly can. Then just leave it in standby for a couple of hours. You should really only lose 1-2% of your battery. If you do then you know something on the phone is responsible and you can start looking for and freezing the suspects.
I've had mine in standby for about 9 hours now (since I unplugged it) and it's at 91%, after only a few texts and emails. That's with data on most of the time and a little wifi earlier. I'm on 2.3.5 and KH3.

Sent from my GT-I9100 using XDA Premium App
The phone is the same, it really is all in the user settings and usage styles. If you want to prove this, just reflash any ROM and kernel (they are not that different) and do a full wipe of the phone. Don't set up a Google account or any email accounts or install any launchers/apps/widgets. Use a plain black background/lockscreen. Just use the phone, SMS and other stock apps for a while. You should be getting around 3 days or more of battery life with moderate usage.
I've gotten 3+ days of battery life before, but nowadays I get less than 1 day. So when I read that other people are getting great battery life, it's not because their phone is different than mine. It's because I need to use Exchange for my office email, or because I want to run a certain widget, or have some extra notifications, etc. So all you can do is keep experimenting, updating, etc. until you find a combination that works well for you.
Can somebody help. My sgs3 battery seem to drain like a loose drain. I charge 100% at 12.30am and go to sleep but by 5am battery is completely drained and phone is dead off. This is not the same during the day. Are there processes running when the phone is Idle that brings about this massive drain. Please I need help asap.

There is obviously a problem if it's dying in <5 hrs.
Did you recently connect to Kies because I was having probs with my SGS2 getting really hot and losing power as a result of Kies/a dodgy USB lead?
A factory reset solved it however ( remember to back up ) but sometimes just removing your battery for 90 seconds to reset the values works.
Good luck.

Turn off Google backup, face awake, try that for starters
First of all, switch off your phone for a while to see if there is problem in battery or its the apps you are running. If you think it is a stupid step,
Then try using some software like JuiceDefender or something.
In app manager, kill apps that are useless.
Also turn off features like bluetooth, gps etc. if on.
Reduce phone's brightness, recommended to set it to "auto".
Turn off useless vibrations and LED notifications.
You should now see significant improvemance in battery life.
Hope this helps
I have taken all these steps gone ahead to remove live wall paper, auto sync disabled, brightness is set at auto. And its still the same. I don't want to tow the line of hard reset because am not sure that would solve the problem coupled with the time it would take to get my sgs3 to suite me

I use juice defender which manages everything for me, an overnight schedule ensures the battery only drops by 1 or 2%
Sent via TCP/IP
okay so i thought i had a battery problem before i tried putting my phone aside (meaning no games, no internet browsing and no video streaming nothing, just using whatsapp and leaving facebook connected. I also have lots of apps and games installed over 15 or something)
If you decreasing screen time you will notice a HUGE difference (24hrs in my case), its basically down to usage, I have tried over 10 different roms and kernels as well as the v6 supercharger script, i dont ever notice the difference, EVER. unless of course i use a minimalistic rom with almost nothing to play around with, but if thats how u like it then go for that. Id say following all the fundamental steps will take you a long way
my final advice:
less screen time
when on the screen use the least brightness available
decrease stock brightness even more if you can
less app usage
if your not one to constantly play with your phone and customize stuff on it try installing a minimal rom like
|ROM|XXBLG8| IOIDroid Super Slim Edition | Buttery Smooth | V1.0.0 LIVE !! |
or
[ROM][4.0.4] Slim ICS (SGS3) - Clean, Simple & Fast (63MB)
i dont know if this is a placebo of not, but sometimes i notice improvements when i undervolt, underclock and limit to only dual core. believe it or not sometimes it has little or the adverse effect of saving battery
good luck man
And another question, which can be solved through the search function or Google -.-

So here is my experience. Have been using android for years, have had an hd2 so I know how to get good battery life results. For some reason I easily lost 15-20% overnight with just the gsm 2g radio on. No matter what I did it drained fast even though deep sleep was fine, all extras sync and etc were off. 3hrs screen on time in 14 hours and it was dead.
I kept waiting for an update to solve this and it never came even though I was force checking it.
I ended up factory resetting the phone and as soon as it booted up an ota update popped up. Since then I am having nearly 6hrs screen on time in 40hrs,which is amazing.

Greetings, I have seen a similar problem back in our hox forums. I have come here in peace to help, though. Recently, someone suggested bump charging, it's like a natural way of making your battery recalibrate itself without wiping battery stats or stuff like that.
First off, charge the battery until it says 100% while the device is on.
Then remove the charger, turn off the power, and charge again.
Remove the charger again when it says full while the device is off.
Turn it on again, then when it's properly booted, charge again, but don't use the device until it says it's fully charged already.
Mind you, we're not sure if it's just a placebo or not. Some claims to have had better battery life after doing this for once a month. I haven't tried it yet, but I thought I could share it here too.

Just to offer two cents from my experience with this phone.
I recently got a replacement for my s3.. the details of that are for another post, but this relates to battery:
when I first got the phone i started using it right away. I did not charge the battery until I got to the office and charged the phone while using it the first day.
when I got the second replacement phone I already had a second battery.
This battery was fully charged and immediately used that in the new phone. fully charged the samsung battery before I used it.
I noticed significantly better performance with the second phone. I think it was because of the way i treated the battery strait out of the box.
any one agree, or have a similar experience?

Do you have an Exchange account set up?
After the newest update i also notice that it has a high % drain even if i turn 3g off, gps and everything nothing unusual runs in the background that can explain high drain yet it does.. and i didnt notice that before the latest update and i havent installed any weird apps. I also have all my weather and news on manual update so i dont get what can drain the battery with internet off overnight.. its frustrating a bit.
Hi,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):
http://forum.xda-developers.com/showpost.php?p=26755476&postcount=850
With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.

that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time.

i like to keep my gs3 connected to wifi and muted while i'm sleeping but when i wake up i always get 8-10% battery drain (in 8 hours app), i come from a motorola atrix which in the same conditions i get no more than 2% drain over night.
i've tried many roms (omega, foxhound, ultimarom...), many kernels (stock, galaxsih, siyah, phenomenal medium and extreme...), and also some basebands (modem, radio) but i keep sticking with the XXLH1 'cause i get less drain with this one. but in any combination i always get 8-10% battery drain during night.
i've seen some of you say that you get 2-4% drain in the same context so i would like to know what am i doing wrong :/

im using the leaked stock 4.1.2 there now, and i had 3% drain in 11hrs between overnight and not using it this am.
seems v good for battery life so far. i know your pain though. its non usage time i want to be high batterylife. id expect 2-3 days from the phone when not playing games etc... im hoping this is gonna fix that now. most reports are good about battery so heres hoping.
in a few days will know more
How is it sleeping overnight? check settings > battery and check how much it's awake when the screen is off, then check better battery stats to see what is waking it up, I would probably say you have too much synced.
you're right, i have too much synced, 3 google accounts, plus facebook, twitter, whatsapp, skype and others but those are the same settings i had on my old motorola atrix and even there i got 1-2% drain, although i was on gingerbread.
i will install some battery stats application to see in details whats draining it so much, 'cause under settings it only says that idle and standby time are the draining reasons.
gonna try the leaked 4.1.2 to see if i get better results, thanks!.

Better battery stats is the best, but that is a lot to sync, I would imagine it's not sleeping well because whenever an app decides to sync it will wake the phone up, and let's not forget the S3 has a 1.4GHz quad core CPU, if it wakes and uses all cores it will drain the battery faster than a single or dual core CPU. I notice the Atrix has a 1GHz dual core, so you should expect a lot more drain especially with that much synced, honestly you shouldn't need Skype syncing unless you always want your skype contacts to be up to date in the contacts app, and Twitter just syncs to pull the latest tweets through, you can just do that manually every time you open the app.

does that mean that jelly bean is making you experience worse battery life?.
maybe it's because the atrix has 2 cores but if the gs3 uses all 4 cores to fetch or sync some data, that would mean it's not very well optimized for simple tasks, thanks anyway i'll try better battery stats

Android doesn't fully support multi-core CPUs yet, which is the main problem, all you can try if you need all the apps syncing is download a custom kernel and change the CPU governor this will change how the system uses the CPU and it can help.
Well for starters, Google Now should be disabled if you are concerned about battery life. Also check for and disable latitude and location reported from maps (they are getting activated by google now) Even if data/sync/gps are off google now constantly polling for updates thus draining battery.
With my HD2 running GB/Froyo for over 2 years, and methodical testing to achieve the lowest battery drain in standby (testing for 8hrs at night) the best I could do in AP mode was .35% per hour which is less than 3% over 8hrs.
I have owned and tested my S3 for 4 months and usually get 1% per hr and in AP mode....I get similar to the HD2 above at .35% per hour but I haven't tested to crazily.
I find it hard to believe and would love to be convinced, that any S3 owner can get less than 3% per hour drain without going into AP mode. Please prove me wrong and state your methods for all to learn.
Finally, I do not find the battery drain to be Linear. I am guessing that a battery charged to 100% sometimes may actually be a bit stronger than 100%. So doing a random single test may result in low drain numbers but that may be misleading. That same test performed at 20% level, may yield worse results if in fact my theory that the battery does not drain linearly...is true. But for consistency, I always perform the test at 100% battery and let it sit in the charger for an extra 2hrs before unplugging it. This way, at least the test is more consistent and more directly comparable.
I now have Green Power app installed and it is able to automatically turn off wifi/data in standby under conditions set by me, the user. I am performing some nightly drain tests. I would be thrilled if I could get between .35-.75% per hour. My first 2 nightly tests failed thanks to Slacker Radio....which held a Wakelock even though I bloody killed it!
I think this could be due to fast dormacy

Read this link first though

A bit off topic but just reminds me of my old Nokia N95 because whenever I was in a network dead spot or just have no signal for whatever reason (Gif fgaff) the battery would completely run dry within maybe 6 hours, and you'd think because it has no signal it should last longer than the few days standby I normally got.
And I've never had a SIM in any of my Android phones that lost service for long so has anyone seen this happen on an Android or is it just a Symbian thing?

When a phone has no signal it has to scan all frequencies for a signal, this constant switching of frequencies drains a lot of battery, it also increases the power to the mobile networks chip to try to pick up even a weak signal, which also drains the battery faster, it happens on all phones.

im using the leaked stock 4.1.2 there now, and i had 3% drain in 11hrs between overnight and not using it this am.
seems v good for battery life so far. i know your pain though. its non usage time i want to be high batterylife. id expect 2-3 days from the phone when not playing games etc... im hoping this is gonna fix that now. most reports are good about battery so heres hoping.

Which I am running but 3% over 11 hours?
Any e-mail accouunts? What do you have enabled/disabled? What is syncing?
The best I have ever managed was about 1%per hour and that was with everything off apart from the cell.

Read the link I posted above about fast dormacy and if this is your problem then get the app fast dormacy from play store
If you're worried about wifi while sleeping also have sync turned off and location in settings and disable notifications from play store and disable notifications from apps also

Will give it a try but I have never seen it show up in BBS in the past hence never tried it (I was aware of it) and as far as I am aware O2 (UK) does support Fast Dormancy.
It is not that I an dubious about the 3% drop over 11 hours I just want to get to the same level!
EDIT: To get the 3% drop do you disable everything you mention above? I use Tasker to disable everything including sync, wifi etc...except the cell. But I do not disable play store notifications seperately.

This is what I have come to expect. 1% per hour is reasonable and typical. 3% over 11hrs...hmmm...I don't believe it.

I have messed with this before without positive results. But anyway, since it seems like you have it working...what is your typical % drain over 8hrs?

I usually turn mine off overnight but if I do want it left on I turn my location settings off and everything that requires wifi and don't lose much.
I'd suggest trying better battery stats from play store then after leaving your phone off overnight dump your results (in settings) and then go here http://forum.xda-developers.com/showthread.php?t=1179809 to ask about your results
