Yet another battery drain thread - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Okay this is messed up. ...
I have an extended 4200 mah battery ... and it drains this much over night?
I'd hate to see this on my regular battery. We recently just got lte in the area ... and in my house I get 2 bars Max.....most of the time none .... could this be the issue? I have BBS but it fails to tell me what is draining unless I'm reading it wrong

Do you have any wakelocks?

Only thing that looks out of the ordinary is whatsapp. But still .... it shouldn't be that bad on an extended battery. Is it because of the low signal issue? I do know that I lose signal in my house often and its a struggle to maintain LTE connection.
I think ill put it into airplane mode tonight and see how it fairs.

If you have a very low signal yes, it will drain fast. When I had my ns4g on sprint it would be dead in 10 hours with little to no use at my house because my area is neglected by sprints towers.

thats VERY annoying.
i just realized that i turned SYNC off. so.. it's definitely the low-signal area. that really sucks. damn. maybe I can get ATT to give me a signal booster.

edit: updated
just did a test, charged battery to full (extended battery). left phone alone for 30 minutes, sync on, full LTE coverage at work. WiFi off. I received about 3 texts, and had a few emails come in (didnt check them, but I did respond to the texts).
In about 30 minutes, the battery went from 100% to 93%. I checked BetterBatteryStats, it said my phone was awake for 22 minutes because of bam_dmux Kernel Wakelock.
gonna research that, charge the phone to 100, turn sync off, and test again.

There's an entire thread about that wakelock, search for it. They've made some ground figuring the cause. Forget where it is though, sorry.

My battery is terrible

Don't know what is going on. In one hour I lost 50%. Attempted to charge the phone with the USB charger and it read as if it were charging but the battery was still dropping.
Edit: I think it is slowing down now that it is at 50%. Sort of like it had a memory of being at 50%.

Coming from a rooted evo, I'm having excellent battery life.
seems like it takes forever to die.lol
Great life so far. Took off charger at 6:30 pm (now 7am) from 6:30 to 10pm moderate to heavy use. then sleep. Up at 6am and now sitting at 65%.
You may have a bad app that is causing it. I decided when I got the new phone that I wasn't transferring anything over (wanted a fresh start) also I install a few and then wait 30min to a hour. Bad apps show up now and then.
Just fyi the Google Music -beta app is one that on my EVO was a battery killer. Has to always kill it when I was done listening.
I wasn't doing anything out the normal. Task manger didn't see a problem with any apps staying open.

Maybe a bad battery?
Either that or you have too many/ evil.apps or widgets running.
It also could be a problem with the built in power management malfunctioning.
If possible do a factory reset, if the problem persists take it/send it back so your not stuck with a borked phone.
my battery life has been great after 12 hours of heavy usage I was down to 10%.
I then charged it and left it unplugged for 8hrs and dropped from 60% to 49% battery.
Pretty spectacular if you ask me.

Widgets
On sense I saw a place to set how often the news and weather widgets would sync. I don't see a place for that on this one.
If you're in a bad signal area the battery gets pounded, but that's pretty much how it is on any other phone. I was in a bad signal area on Friday when I got it and the battery drain was a lot. Now that I'm in a good signal area, the battery drain is almost nothing. I have about 3% battery drain/hour right now, when I'm not using the phone. I also run skype in the back ground all the time. I'd say that's pretty damn good. Oh and skype is amazing on this thing, especially if you are on wifi!
this battery is phenomenal. Loving it

Battery draining way to fast

I let my phone completely die last night because I wanted to get a full charge on this thing. I wake up this morning, and after 4 minutes, it had gone down 4%. It has now been 7, and it's down 7%. Anything I can do?
PS, it is now down to 90%.
Running Calk's rooted FC15 with ics4ics theme and the lockscreen mod.
88% now.

Been on it since Sunday. Location services are not enabled. Yesterday I noticed it had gone down faster than before, battery only lasted just over 8 hours with minimal use, but the wifi kept disconnecting, as did the 3g when wifi was off (this didn't happen in gingerbread).
I wonder if I don't need a new battery. I have noticed battery performance getting worse and worse over the past couple weeks.

I would take your battery and have it checked at Sprint. They will replace it for free if it's bad. My battery gets better after a day or two. I lose 2-3% while asleep on wifi and regularly get 4-6 hours of screen on time depending on how I use my phone. Did you check your wifi sleep policy?

Check what accounts you have setup, and if anything is syncing.
Goggle+, dropbox, and other applications have auto picture sync options which will KILL your battery.
Also location services in google or westher applications, and as always poor signal or no signal.

Sync is always turned off.
Well, I tried something: pulling the battery for a minute, then when back in, plugging it into the charger. I would give me a false full battery light, because when I unplugged, it showed 90%, and it kept doing this every percentage point, so I kept unplugging and plugging until it showed 100%. Well, 10 minutes have past, and it hasn't budged. So I'm chalking this up to false battery stats.
Thanks for your suggestions!

How many apps do you have installed? Could be a rogue app in backround eating your battery up.
Also with wifi/3g constantly disconnecting also taxes that battery juice faster then a constant steady signal.

FYI, I am having this same problem on the same ROM for the last couple days. I thought I had isolated it to a problem with having USB debugging running when charging from the computer but that's not it either. Last couple days battery is draining so fast that I lose charge while plugged in! Have to charge from wall plug to get an increase in battery. I am having Android OS AND Android System at the top of my battery stats eating 35% and 34% respectively. Clealry not due to syncing or email checks or anything similar as this is the exact same setup I have been running for months (other than the upgrade to Calk's ICS ROM). I'm baffled....
Install these 3 apps:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
This app will tell you what is holding wake locks on your device. Anything over 30 minutes over the course of a day would be problematic imo. But it depends on what you have installed.
https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy
This will tell you how much time your processor spends at each clock speed. Deep Sleep should be close to 80% with moderate use.
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
This will show you your percent per hour usage of battery. It's optional, but it helps me debug battery use. Typically I run 3-6% per hour with moderate usage.

So it figures, downloaded those apps, rebooted the phone and now its not happening anymore. This has been the problem the last couple days, its intermittent so I keep thinking I've figured out what's wrong and then it happens again. I'm thinking about going back to Gingerbread or trying one of the AOSP roms to see if the problem persists...
I noticed FC15 has the worst battery of all the leaks so far. It a joke shouldn't have even been sent to sprint for testing.

Gonna have to disagree with you there, maybe you have a bad flash. I'm getting an average of 16 hours with fairly heavy usage. FC15 has been fantastic, no issues whatsoever.
Im having kinda the same problem. I just had to get my rooted phone replaced yesterday not that it matters it was rooted I had no roms or nothing on it just rooted at the time, but my battery was fine. I got a white one I havent rooted or nothing yet and battery is going fast. I kept the battery from the previous phone. I was looking through appbrain and seen the app "bad ass battery monitor" and my kernal is killing my battery as of today.
Argghhh Bricked it!
Tried going back to Gingerbread and hard bricked the phone! 5 years on android and four different phones and this is the first time I really truly bricked. Blue led on and not a thing else.
Well I guess getting a new phone is one way to get back to Gingerbread.... For now, I'm sporting a cutting edge Blackberry tour!
Why is this phone so easy to brick? I've had 4 other Android phones and I see more bricked posts for the e4gt than all the others combined...

Before the ICS leaks, this phone was virtually unbrickable. Once we get the ICS source and the recovery issues are sorted out it will be that way again. If you stay clear of wiping individual partitions and follow directions in OP you are safe

EXTREME Battery Loss (CM9)

Greetings!
I am currently using a Sprint Epic 4g (SPH-D700) with ICS (CM9-epicmtd) and the regular Cyanogenmod kernel. I have followed the guides on here and on the CM9 forums for battery life including blacklisting certain apps, changing settings, messing around with performance settings, etc. With all of that, I usually get around a 4 hour battery with normal use (Spotify Music, GVoice Messaging, Occasional Reddit App), during school I have to charge it every other class or else it will die. I have become used to carrying my charger around but I think I figured something out so I wanted to know your ideas on it.
At home, I only use Wifi, I turn off 3g access. I can get 8hour battery at home. But right as I turn on 3g, I get MAJOR battery drain and the phone gets extremely hot.
I just wanted to know, is it the phone? The battery? The OS?
Thanks
-Dier
USe this app (http://forum.xda-developers.com/showthread.php?t=1179809)
It will show you what processes/apps are eating battery. I'd also suggest you do a dry run with turning off all sync/streams/data usage for a day or so to see how the battery reacts. Chances are good that you also have an old battery.

pull your battery out and pinch it if it feels any way shape or sort spongy , go to sprint and get a new one they wont ask any questions if you have insurance and your in and out in 5 min
Didn't wanna make a whole new thread so I hope this would be the right place to post this since I also want to know "is it the phone, the battery, or the os?" lol.
I'm having terriblee battery results with my phone. Its been happening for like 3 weeks now and I thought the reason was because my batteries got wet (I have like 5 batteries, 4-1500 mAh, and 1-1800mAh). They all die pretty quick I can get about 2-2 1/2 hours of screen time in about 12-14 hours. Which is terrible cuz I have screenshots that I randomlly took of my battery from before and there's times where I would get 4hrs of screen time on in about 20 hours total or I could go about 30 hours with 3 hours of on screen time. I've tried different ROMs and even odined to stock and tested things out and still my phone dies super quick.
My questions:
When the battery has water damage the little paper tab thingy turns pink right? What if it is removed completely?
And is there anyway that my phone just isn't working right because of having damaged battery?
Because right now I'm using a 3500 mAh battery and I'm getting almost the same results that I used to get with my 1500 mAh ones.
Does anyone know anything I could try to see what happens lol?

To cure your problem. ....
New device for first time comes to life doesn't have calibration set by OP system. .....
So first charge your phone to full and go beyond warning to charge and go down to 3-4 % remaining charge then plug to charge and charge without stopping to 100%
And do 2-3 times like this then your battery discharge will show properly
Also good habits are to use .....
Hold home button for 2-3 second and open little bottom screen click on bottom left and choose ram.....then clear ram....any time you going to idle and each time you going to charge. .....to find more about what this do search XDA .....
Also there is many hungry apps on market that runs under ground all the time. ....so learn and discover how to take control of your phone and make it run like champion
#2 you can use ES task manager to do some fine tuning to get the most juice of your battery
#3 Better battery stats
#4 Battery booster
#5 Juice defender. .....are some alternative to top of the iceberg on your solution. ....or you can take time and learn to do all this by yourself manually

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.
I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

The battery is obviously defective. You need to get a replacement.

I'd have to search around, but taking these batteries all the way down actually reduces their effective life.

Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.
