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.

How long have you been on that setup? I know my first couple of %s go quick but after that everything settles down. Do you have location services on by any chance?

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.

Yeah, I forgot to mention the sync options. That taxes the battery big time
Sent from my Nexus S 4G using xda premium

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!

Yeah, I was going to mention wiping the battery stats but I figured someone would say that does nothing. I always do it when I set up a new ROM even though some do it on install
Sent from my Nexus S 4G using xda premium

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

Mine has been horrible and have no idea why. I haven't changed apps or anything from previous installs or settings but Android OS loves to eat 50% of my battery which is a good 25% higher than normal.

(UVDLI6 JB) Sudden Battery Drain

So I am running UVDL|6 for some time now which works good (not great but good) and this morning I woke up to find my battery completely dead. When I went to sleep it was at a decent 55% now I highly doubt that without any use the battery just drops to 0%, So checked my battery stats and it says Android System at 70% use.. which is pretty high for an idle phone. Any ideas? Or any software I can use to pull out the culprit because Android System has so many subsets to it that it makes it really hard to pin point what causes it.

You will have to reproduce the problem, but try GSam Battery Monitor.

Reproduce the problem? Well I was a sleep so maybe ghosts were messing with my phone, I'll ask them nicely...

I think he means you need to put your phone in the same spot when you go to bed and see if it does it again. No sense in trying to fix a one time problem.
Battery stats were gone when you started the phone up I'm assuming. Good reception where you placed it?

Been happening to me on LI7 lately. Originally it was great on battery life, then all of a sudden I started getting insane battery drain from the Android System. I haven't really taken the time to diagnose it yet, but I need to. It gets really hot randomly sometimes then cools down and the battery just starts draining away really fast.

I saw someone mention deleting or renaming gsiff_daemon in /system/bin to solve this.
Theres a thread dedicated to the subject as well, though ive yet to actually go through it.
Anyway give that a shot and lets all hope they Completely fixed the battery issues in the final release! (Its not all from one thing in my experience with the leaks, but from multiple issues)

Ill add my stock experience for reference as well as if anyone has a fix. I'm pretty happy with battery life coming from a Vibrant but what I notice is that usually there is minimal drain during the night ,however if I get an SMS the drain will be maximal.Like 30/40% Almost like the screen went on and never shut off but it doesn't seem to be the case. This is on the stock messenger App. If I don't get an SMS it will usually drain from like 99% to 96% roughly. Didn't mean to threadjack OP.

[Q] Short battery life

I've had my Galaxy W for just over a year. Whilst I was running the stock ROM I would more or less get a full day out of the battery. I upgraded rooted my device and installed the Cyanogen CM9 rc2 ROM. I don't recall any battery problems at first, but just over a week ago it started draining within five or six hours. This happened every day for a week.
Since then I have uninstaleld all apps (apart from Google Authenticator which I couldn't manage without), turned off wifi, bluetooth and everything else I could think of. Now I seem to be getting about 36 hours out of the battery... Although I think it goes from 35% down to 10% very, very quickly.
Leaving all data connections off and having no apps is okay in the short term, but is there a long term software solution?

Not immediately, but about a week later. Is it worth going through that process again?
Edit:
This is the app that I used:

Before I uninstalled any apps I downloaded and installed CPU Spy. Here are two screenshots taken with CPU spy.
I could reinstall it now without any other apps installed, if that will help?
I don't know enough about this, but I expected that the phone would spend a higher percentage of it's time in 'deep sleep' than that.

That should have been right. I don't know what is happening with your deep sleep, although your phone is on for 16 hrs but the deep sleep only reach not almost half of it. Did you use your phone often?

Interesting.. how about you check on the battery is it bloating or not?
For battery problem is either the phone calibrated wrong readings on the battery or the battery it self is the problem.
If you use your phone not too often but the deep sleep only reach 34% of the time then some apps is preventing the deep sleep, try to check what apps is that causes that with some battery stats app, try search it in xda or market

I've gone for Battery Stats Plus. I'll reenable wifi, bluetooth and 3G for a few days and see what happens. If that takes a toll on the battery I will post back with details from Battery Stats Plus.
I will also take the battery out later to inspect it.
Update:
My battery had 15-20% remaining and I turned it off, and tried to turn it back on. It now thinks that it does not have enough power to boot the phone. I don't know if that new information is helpful or not.

With 15 - 20% it should have boot, because it still have juice left. What about your battery physics? Is it bloating or just normal?

Took the battery out this morning for a proper look. There's definitely some bloating. Time to get looking for a replacement battery?
Could there be two issues here? As from the screenshots I posted the phone doesn't seem to have spent a lot of time in deep sleep.

I was just watching a YouTube video, with about 70% battery. The phone turned off, and when I've turned it back on it's gone down to 2%.
Could this be down to an improperly calibrated battery, or is it purely down to the physical damage/bloating to the battery?

Thanks for your advice.
I'm going to install Battery Calibration by Nema from Google Play. I'll see how I get on with that.
I'm going to order a replacement battery this week. I'm looking for a direct replacement, with an official Samsung battery. I have posted here in the Accessories forum. I hope that was the right place to put it.

After I install the CM10 alpha 6 conform to the first post, the battery life of my cellphone has been drained very fast - 21% about 6 hours and half.
Can anyone help me, please? I already did the battery calibration and I can't see effects. I'm wondering if is better install CM 9 or just go back to the android 2.3.6 factory version of my cellphone.

Your battery is bloated? Then you *must* replace it. Period.
A damaged battery is the root cause of myriads of problems. Until that battery is replaced, you _will_ experience all kinds of annoyances, no matter what ROM/Kernel you're using, including inexplicable battery drain.

This is it !!

I am extremely frustrated. My phone has always been bad with battery life. Its been over a year or so that I have not seen my phone last longer than 5-6 hours. I am constantly looking for any chance I get to charge my phone. My life revolves around checking battery %age and plugs to charge. Smart phones were suppose to be helping us, but its like they are using me to feed the juice every chance they get.
My T989 is a "SMART" phone with
- lowest on screen brightness (and a screen dimmer overlay)
- no NFC
- no haptic feedback or keytone sounds
- No animations or graphic heavy launchers
- dont play games any more
- turn off 4G/data anytime I get a chance
- No GPS
- Manual Sync emails, facebook and whatsapp
HELL, I want to go back to the age of Nokia's where the batteries would last you through weekend and still some juice left even after it goes through laundry.
But that is not what I am here to complaint about.
I would like to know what ROM+Kernel you have and how much battery life you get ? (w/ screen time)
Who else is going through these ?
Note: Currently on JB stock and a new OEM replacement battery

How often are you using your phone? It uses a lot more battery when the screen is on. You can get over 24 hours of battery life by not touching your phone at all/no apps running.
I think most people average around 3 hours of display time without charging. Check in settings/battery/display.
I'm running AOKP and depending on how often I use my phone it can really deplete my battery.

easiest way i have found to extend my battery during the day is to toggle my data..if i am not using it for a bit, just toggle it off, takes 2 sec to toggle it on, and can easily double my battery life..

Do this stuff and read it carefully. And yes 3 to 4 hours is about average screen time. Makes no difference discussing total battery time. You can kill it 3 hours from a full charge with continuous use...or it can last 24 hours....all depends how often your using it and what you are doing with it.
If you go thru this other thread and follow all of the advice ....you should be fine.

These are my results, after buying the LAZA 3800mAh battery. I just had it for one day and it is light years ahead of the stock battery. I don't use NFC, and my brightness is all the way down. (Still I don't believe the brightness is low enough, seems too bright). I am a student so when I'm in class I can't obviously use my phone, so that is why the screen time is below what you guys expect. Still this battery is legit! I got it for $23 shipped (Amazon Prime). On the stock battery I had to revert back to ICS, but with this Laza battery I have no gripes on leaving it on the latest CM10.2 (4.3.1) and letting it go on Dual Carriage (DC, HSPA+42) mode. As long as I leave school with more than 70 percent battery like on my HTC Sensation, I am fine.

I do have GSAM battery monitor installed. I had it installed since it was called "bad ass battery monitor". It always is consistent and shows that screen uses most battery (abt 35% of overall usage), even at lowest setting. I also have a screen Filter app https://play.google.com/store/apps/details?id=com.haxor That overlays on the screen that dims it even further and is believed to save some more battery.
The other major user is the apps which is
- Android &
- Kernel

Dude.....less than an hour screen time tells something is very wrong.
First...I would bet the screen dimmer app Burns more battery than it saves.....that'd be my guess.
Second....flash a fresh rom, or stock. Run it at least a few days as is. With only gsam and cpuspy installed. Nothing else. I know you may really miss some apps....but its the only way to see if its an app, or rom, or hardware.
Then off gps after your install. Its on by default and is a huge battery sucker.
I'll bet things will be greatly improved. Then install apps.....monitor closely for changes in gsam or cpuspy.
Your screen battery usage should be more like 60 percent or higher....even as dim as it goes. That's normal. Apps, maybe 30 percent and then the other stuff. A 35 percent battery drain from the screen says you have problems.
After all your apps are installed.....try everything in that link I posted. Everything. And things should stay good.
Keep us posted.

wow, and i thought mine was bad... i have my screen on alot and play 3d games, i guess im doing good. running slimbean.

I do believe that the battery life on this phone is not the greatest, a spare 5$ ebay battery in the wallet keeps me worry free

Bad Battery Backup??

Hi,
I have been getting only 20 hrs of battery and only 3 hours of screen on time. I have not used any processor intensive apps. Please check the images attached. Is this normal? I have bought it a week ago and I can get a replacement if the battery is defective. What do you think? Don't plan or rooting it.
P.S: I have chosen ogp over n5 because of the extra battery, but ogp's battery is equally bad.

Normal usage.
After playing 1hour of injustice i get around 3.30 of screen on time.
WiFi always on.

You need to understand that they provided the extra 'oomph' in the battery department, because this is a HUGE screen.
Another thing, is that LG's stock interface is filled with a lot of white menus, and submenus, etc.. That will also impact battery life more than you know.
Another factor to bring in to consideration is the cell coverage. Your phone has to work harder to acquire signal, in hard to reach places by your carrier.
All of these and more (wakelocks, no deep sleep, etc..) Have a big impact on your device's battery life.

after charging it to 100% battery the CurrentWidget show still charging so i guess
leaving overcharging will make it last longer
