might want to turn down the screen brightness to under 50% if it isn't already, and set the screen timeout to a lower setting, 30 seconds to a minute. other than that, disable all the bloatware and you should get at least 15-20 hours.

Check screen on time and write it here.

I am using app called deep sleep battery saver. It puts your phone in deep sleep whenever you are not using the phone. In whole night only 1% battery used. I get minimum of 1 and half day of battery backup.
I see mine only drains fast when i am using 3g data connection.

Battery issues are very hard to troubleshoot over a forum. Turn off anything you don't need, i.e. WiFi, GPS, Bluetooth, etc. Looks like your screen is sucking a good bit of battery. I use my phone as a WiFi hotspot at work and it gets me through the night. Not sure what your specific issue is. Try one of the battery saving apps.

Wifi always on

I have noticed my battery losing about 8-10% when in deep sleep. It's set to keep the wifi connected constantly as default . Is it better to keep it on or off whilst the device is sleeping?

Off to save battery otherwise it keeps searching .

If your not to worried about getting messages early hours of the morning, just turn Wi-Fi off.

"Losing about 8-10%" over how long?
The problem with setting WiFi to sleep when the screen's off is that the phone will still try to auto-sync overnight, meaning that it will use mobile data instead. Ironically, that may use more battery life (and mobile data) than having WiFi on permanently. It doesn't drain that much power.
Additionally I don't think it will keep searching for other WiFi networks as long as it's connected to one already.

I think it`s high, i lose about 3-4 percent at night, about 7,5 hrs. Have wifi on and full sync. Maybe you ought to check if other apps are causing the drain. Install cpu spy from the market if your phone goes in deep sleep.

Battery drain

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.

Do you leave many programs running, alot of frequent sync going on? Did you leave Bluetooth on or something that you don't need during night? Just guessing...

Search battery drain on Google for this device....lots of results,b but it generally comes down to learning how to use your phone and it's features, and when and what stuff to turn off etc etc
I don't leave anything on. I ensure I disable prefetch on my YouTube, disable auto updated on dropbox, I don't use SNS, and off course screen time out after 10 sec.

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 -.-
http://forum.xda-developers.com/showthread.php?t=937080
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.

I will try the juice defender route and hope that it solves my problem or else I will be forced to tow the hard reset route.

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.

I saw this method being used with good results (reportedly) on my SGS2 so it's definitely worth a bash if you can't be arsed to reset.

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.

Xperia Sola battery drop 5% per hour without use, is it normal?

Dear Brothers & Sisters,
My new Xperia Sola's battery drop 5% per hour without any use. 3G data is on, but background data is off (as i have started the power save mode).
Background running app only facebook and whatapps, is it normal that battery drop 5% per hour with screen off ?
Thanks!
doesnt matter if backdround data is off, facebook WILL try to update the timeline in the cycle you've set it to. so yea pretty normal to me as the sola doesnt have a huge battery.
Same problem here too!
Even if you don't use your phone still the battery drops almost at a constant rate of 4% to 6% and that is very annoying. Hoping Sony would fix this issue with their next OS update.
But sola users have an extreme advantage of fast charging. Sola charges itself about 12% in hardly 10mins. Thats the better part
Sent from my MT27i
Hey guys,
5% an hour is 20 hours. to me that is pretty dam good. i used to get about 16 - 18 out of my arc S. with everything on.
Your Data connection is a mega killer weather or not you have background data on or not. it is the connection to the tower that drains the battery.
my arc is now just a phone for work and without the 3g on I get over a week out of it.
we all need to remember that these phones are not like the old nokia's and stuff. modern phones need modern charging habits
Pvy.
You shoud deactivate LiveWare widgets and services because it consumes a huge amount of power. Sometimes I get even +48 hours of standby on my Xperia U.
Try this out! It worked for me!
Okay! I fiddled with my phone a bit to improve battery life and it did work!
Go to settings> Applications> running
check the applications using a lot of RAM and has been using the phones active state for long time. Delete those useless apps. Also apps which connect to the internet uselessly consume a lot of battery!
It worked for me! Now my phone discharges just about 2-3% in 6 hours. Its because earlier my phone wasnt going into deep sleep mode where it consumes the least battery!
Now its battery standby has boosted up a lot!.
I'm happy now!
Try and tell me whether it worked for you guys or not!
Yeah. Disable Bravia display, reduce brightness, switch off data and WiFi, kill useless running background apps, disable widgets. I lose 2% battery in 6 hours in standby mode. I do these before sleeping and its damn effective. Also root ur phone n install autokiller memory optimizer and set aggressive values. This enhances phone speed and also battery is improved

Weird wifi problem

Hello, my Atrix wifi keeps turning on automatically after some time. Not sure what's causing it to turn on by itself. I don't want to use wifi all the time, but every time I turn it off, its back on after an hour or so. I'm running neutrino 2.9, and undervolted the CPU. Performance is excellent and the battery lasts more than a day easily. Just trying to fix this one little issue.
Any suggestions to fix this? Many thanks in advance.
Cheers
Sent from my MB860 using xda app-developers app
Go to Settings -> More Settings -> Mobile Network and see if there is an option for Automatic Connections.
I've not used neutrino in years, but one possible reason is Wi-Fi supposedly saves more battery compared to 3G. So it might be set up to always seek hotspots to save battery.
Sent from my MB860 using xda app-developers app
Thanks. Looked around but I don't see any setting. But your point makes me think. If wifi saves battery then maybe that's what I need. I intended to turn off wifi to save battery since my emails sync just fine with mobile data. I'll read more and find out. Thank you!
Sent from my MB860 using xda app-developers app
I don't use 3G, just 2G with Wi-Fi is always on, GPS is always on, Bluetooth is always off. I get about 7-8 hours of constant use. (screen on entire time) and about 14-18 hours with average use. This is using CM10 and were about the same with MROM.
Attached screenshot shows a decrease of about 10% every hour. If you're getting better battery, then 3G is probably better.

Stamina mode works when it wants too?

Hey guys, so the title says it all, it sometimes works and sometimes doesn't.
I'll have the screen off for 40 minutes and when I turn it back on 3g and WiFi will be on
I had to download another app just to make that feature work

Read what STAMINA mode actually does.
It is very, very clear.
It does NOT turn off Wi-Fi/3G/4G - it maintains the connections so it can allow for a seamless sync without waiting for a renewed IP address each time you turn on the screen.
It blocks your apps abilities to actually use your Wi-Fi/3G/4G whilst the screen is off, unless the apps are added to the exempt list.
I use juice defender and it works very good for me. I've always used it
Any difference in battery life ?
Sent from my C6833 using xda app-developers app
when I use juice defender sometimes I go from 100% to 99% sometimes i'm still 100% in the morning on 7hrs night time. without it I go from 100% to 90% or 89% or lower. do the math. but that's me. any body else could have different results
