I decided to do a "best case scenario" test, and see if some of my battery issues were from apps gone awry, or some other drain. I pulled my phone off the charger right after it went green, and let it sit on the table. Wifi is off, BT is on, and I'm using my airave, so the signal is a full 6 bars all the time. I have 3 email accounts configured. Two of them are direct push, and one is an IMAP poll once every 15 minutes. Few, if any, emails were received during this test. The breakdown is like this:
4hrs, 32mins on battery. Battery currently at 92%
Cell Standby: 33%
Phone Idle: 32%
Display: 23% (the display was only on for about 30 seconds of the entire test)
Bluetooth: 4%
Maps: 4%
Android OS: 4%
So at least i know there isn't a process running that is making my battery next to useless. My battery seems to be getting slightly better with each day of use, but I still can't wait for the extended battery/cover to be released. I really got used to that on my Evo.

that sounds a lot better than my setup.
I went from a full charge to 50% with very light usage in 8hrs . I've been asleep for over 7 hours.
Display: 29%
Cell Standby: 27%
Phone Idle: 26%
Android OS: 7%
Voice calls: 5%
Maps: 5%
However, I have horrible reception in my house, even next to the windows. All's fine as soon as i step out the door.
I've found that a weak signal has a dramatic affect on battery life with these phones. They do so much syncing in the background, and it takes so much longer with a weak signal (not to mention it has to transmit at a higher power). The signal makes all the difference.
Call sprint and get yourself an airave! They gave me mine for free.

do you guys have the display setting on auto or low brightness. My display usage is always through the roog. I am getting decent battery life. I turn 4g off usually and just use 3g unless I am gonna watch youtube videos or sometihng.
I unplugged the phone at 7:15 this morning and I have email, facebook all syncing. wifi off and I am at 92%. So far this phone is being very good at battery life, specially after the first few cycles.

I have mine set at a number. I use a program to change my brightness at night.
7.5hrs & 70% battery left!!
Is it better to have the brightness automatic or a number like 30 percent?

I just use auto brightness, I had about 11 hours use and 80% remaining taking a bunch of pictures, a little navigation and texting. This is with wifi on about half the time.
My battery was crap for the first three days with the phone, after calibrating the battery and giving it a few cycles its been really good for me. I do top off the battery usually before I pull it off the charger for the day.
I have mine set to auto and I see it changes even as I'm typing this message. Truth be told, the battery does drain when we don't have good signal...

Auto brightness us worse for your battery. This is because it has to use sensors every set time interval to check the lighting. It's not a TERRIBLE drain, but over the course of 4-5 hours it would probably save you 5-6% if you set it something lower .
And to the other person who asked, your battery life is SIGNIFICANTLY lowered when you have poor signal. What happens is your phone's radio draws extra power when it has poor reception in order to boost its range/signal. For those of you who work in places with poor signal, I bet you can attest to this
Also, I have a few battery tips in my signature if you're interested in more. It's slightly outdated (as in there are more methods now), but everything in the article is still true

Fully charge your phone, then use it until the battery complete drops...Then charge it again
How many cycles have people run on their batteries? IE full to dead?
I have auto brightness, GPS on Bluetooth on, email sync every 3 hours, weather sync evey 3 live wallpapers, and I forget the rest. Battery lasts me 12-24 hours, which is about what I got with my Hero modded out with setcpu and etc. I like the battery life of this phone.

My phone died in about 6-7 hours of steady drain, then I calibrated by doing the same thing they told us to do with the OG evo.
Charge over 8 hours, turn off the phone charge another hour, turn the phone on charge another hour.
I top off by using the phone for a couple minutes, then putting it back on the charger until full. The phone clearly goes down to 95% from full while charging and back up, I like how on this phone you can see that it does it on the battery graph so you know.
I've had my phone off the charger for like 34 hours and I'm at around 48 percent battery remaining. Not heavy usage but not super light either.

69% as of now. I had to reboot today so I can't say this is average. I know there are issues that can't be fixed until root, but as a stock ROM, it seems the power management isn't half bad.

Sense has always been pretty good about power management (especially when you consider the puny batteries they put in their phones), and an asymmetric dual core processor definitely doesn't hurt haha
So, I went to sleep at full charge, took it off the charger to see how my drain was....I woke up 6 hours later and it was at 64%. I took a look at partial wake locks and it looks as follows (I can't upload .png from my phone)
RILJ (Dialer) 205s count 2178
juicedefender 3019s count 1570
Alarm manager 1543s count 1320
Google services event log also has a pretty high count. I ran the "battery fix" and all that jazz,recalibrated my battery,not sure why drain is so terrible?
Could someone please help me out?
I am running cm7 with faux 0.2.0 1.3 kernel. I have it undervolted and profiles so it never goes above 1ghz unless on ac charger. (456 when screen is off)
Sent from my MB860 using XDA App
I'm not sure how much it helps you with your issue, but for me JuiceDefender works very well. I would otherwise have a multitude of data sync apps such as Gmail running, and this limits it while periodically enabling sync.
Start tweaking what apps are using data and the battery life will be better.
I have had a problem the same where I am not so sure juicedefender is helping because I tend to set my phone on the desk when I do homework and the screen comes on after I put into sleep mode and then no more that 5 seconds later it turns on at about 25% screen brightness then jumps to 100% them dims to 25% then goes off, all in a matter of between 10-20seconds. I loom at the battery use area in settings and standby is at least 40% & display is right under and idle is next. my settings that I think may be causing this are the mobile data where the autosync is set at enable (in juice defender) & I tried ping but it does the same thing. I just want to know why the screen comes on ever 5 seconds. I don't know how to contact the developer to try and resolve my problem. I am actually on a thunderbolt but that shouldn't matter. I just wanted to reinforce that "i'm not sure juice defender is working as I get about the same battery life".
Xoom Xoom
I get double the life out of the same roms. I'll try a rom for a day then run juice defender and get a day and a half. Depends on how you have defender setup. The only thing I don't like it doing is disabling my wifi as It sometimes won't reconnect back unless I manually do it. I think setcpu is a joke though. I had it set for 216/456 at screen off and it was running at 1200 for 1/2 the time it was supposed to be asleep. Then whne I opened it up...(Battery less than 50% stay below 1000) and the screen booted up 1300. So to me it's an extra service I don't need.
JD has always given me more battery life on any rom that I have tried.. I recently got rid of it and am trying out GreenPower. so far GP seems to work a bit better than JD. I get a bit more life out of my batter than JD gave me.. try green power out if JD is not cutting it for you.. GP seems a bit lighter as well.. so, could be overall why get more battery life out of it..
Zug
Juice Defender seemed to do little to nothing for my phone. I got rid of it and my battery life remained the same. I can't say the same for everyone else but what works for you might not work for the next guy.
All I'm simply saying is give it a shot and test it out religiously before you make a decision to use it or not.
Works for me another good thing to do if you use set CPU underclock the hell out of it when the screen is off not using it so why not

I have JD configured to run my syncs once every 15 minutes for 1 minute. It is also disabling mobile data while the screen is off and wifi when inactive for 1 minute.
Not sure what else I should do here? Should I re-flash CM7 with the battery @ 100%?

Install the battery calibration app and see if your charge at 100% shows 4000mV+, if it doesn't, that means your calibration is off and you need to search for juggernaut's battery thread and follow the instructions on that to fix your calibration.

Barely saw any gain using JD...only used it on my Dell Streak though. The atrix will go 2 days if I need it to so I don't see any need for JD.
I m using JD for nearly 2 years now and I have to say that it DEFINITLY improves battery-life - just by letting it switch off your 3G when you don´t need it you save a lot of juice.
When I still used my Captivate as my DD, JD helped alot. With all the firmware leaks I was reflashing my phone all the time and constantly testing different kernels/roms/apps for battery life.
On my Atrix, it hasn't seemed to help nearly as much. Not sure why... SetCPU with faux's OC/UV kernel has boosted battery significantly though.
I got lots of wakelocks using it. For me it's better to turn off data manually.

+ 1, it instantly topped the wakelocks. I thought I'd give it a go & bought the full version; un-installed 6 hours later. Maybe it works well on cm7? I'm on Nottach's Dark Side.

Sent from my MB860 using XDA App
Interesting. I'll have to try green power. JD said my battery multiplier was 2.10x when I used it. It could just be making that up though. I got 28 hours of life from the atrix and still had 40% battery left (moderate usage: frequent texting and periodic data+wifi usage, I think a 20-30 minute phone call too)
I swtiched to green power. Didn't notice much of a difference in battery life, but Gp is certainly a lot easier to use.
Hey guys,
I have been running unnamed rom lately, but on any other rom including stock. My battery lasts for like 8 hours with little use and 4 hours with moderate use. When I see what is draining my battery it looks normal as the display uses the most, but I only have it at 30% brightness most of the time I have insurance should I see if I can get a new battery? Or any other tips?
Can you post a pic of your battery usage?
Have you tried to calibrate the battery yet?

Many things could cause battery drainage, such as oc-ing. You could find the original Samsung battery on eBay for a cheap price. Before buying one, try doing the following:
Clear OC/UV settings (i.e. put to defaults)
Download Battery Calibration by NeMa (on the Play Market)
Charge your phone and wait until it reaches 100%*
Tap on "Battery Calibration" and done
Once calibrated, use your phone as you normally would until the battery dies. Only when it dies you can charge it. You can charge as you please from then on.
Note: If it does not reach up to 100%, go to CWM and clear battery stats.

Which other firmwares? Anything UCKK6-based has known documented wifi drain issues.
The usual applies - look in battery statistics, use BetterBatteryStats to hunt wakelocks.

have you installed any new apps recently? those apps that use a lot of apps in the background are a pest to your battery life as they usually won't show up in the battery monitor. try disabling your data when not in use and see if that helps. if the current rom you are on does not have a toggle bar with data use the "data enabler widget" by Farproc.
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.

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.
Hey guys so the title says It all really, over night I can lose up to 10% which isn't normal I know
If I charge my phone up and use it straight I'll get about 5.5 hours out of It ( screen on time ) but if I don't use it to intensively it'll be about 4.5 which doesn't make sense
Sometimes when I reboot the device it goes down by a few percent as well, anybody had this issue?

That's strange. Do you have a lot of IM apps and widgets/apps that updates in the background? As you probably know by now, you shouldn't see more than 1-2% drop in battery in 7-8 hours if you don't touch it. I'm on GPe now that doesn't have the fancy battery saving features, and i'm getting very good battery life. It's currently at 70% after 10 hours on and 2 h 30 min screentime.
It's probably something that's going rouge in the background, but check your apps that updates automatically.

Nowp. Got Stamina mode on, with only 2 exceptions: email + weChat, and also see a 10% drop each night.
I assume the problem is that Wifi or Data connection do not get disabled in stamina mode. You expect them to be disabled, until a request comes from the programs for a "poll event", reactivated, task finished, and then disabled again. But from what i can tell, the connections stay live.
Have you try juice defender. I use it better then stamina. I only have home page and none live wall paper and I only get 1 to 1.1/2% loss all night from 100% to 99 or 98 in the morning

I have noticed this once or twice before, last culprit was google keyboard in about 8h overnight it was almost always awake (about 50%), almost 2h of cpu time, used near 400meg of data - this was in SlimRom
Last night I had 81% battery before I went to sleep at 10:00. I then put my Xperia Z Ultra in Stamina mode. At 6:05 (8 hours 5 minutes) after my battery dropped to 80%
Therefore I only lost 1% overnight which is excellent.
Damn. Thought i was getting decent battery life (currently at 1d 6h on, 5h 25m screentime), but the way you're going you might reach 7 hours screentime on one charge...
And the cp12 isn't currently available where I'm at. Bummer.

As you probably know by now, you shouldn't see more than 1-2% drop in battery in 7-8 hours if you don't touch it. I'm on GPe now that doesn't have the fancy battery saving features, and i'm getting very good battery life. It's currently at 70% after 10 hours on and 2 h 30 min screentime.
It's probably something that's going rouge in the background, but check your apps that updates automatically.

That's really good, I'm on 70% with stamina mode on and 1.5hour screen on time
I'm thinking maybe my battery needs calibrating using an app? It shouldn't drop that much and it shouldn't drop a few percent by turning it on and off

Those battery calibration apps are a complete farce IMHO, modern batteries don't have their own internal memory like the old ones did, the best calibration you can do is a full recycle.

Yep. Also had a out of sync battery. Fully loaded ( green light ), it still showed 97% on the meter. So i drained the battery down to 1%, charged up to 100%, and voila ... Battery indicated correctly 100%, and has been correct every time.

just a reminder that the LED turns green at ~90% not fully charged
If you are in an area with very poor cellular reception and your cellular radios are on this can happen. It would help if you would post some screenshots of your battery usage in different scenarios; otherwise we can't help you too much
You could have a transistor leaking current or a short somewhere inside the device. Try a factory reset if you've exhausted all other options and if it persists contact Sony.
