Battery seems to be draining more than it should overnight when it's not plugged in. Wifi is by far the largest battery eater. Any way to deal with it?

Well actually the wifi sleep policy should be never. Wifi uses a lot less battery than 3g does.

Well, according to spare parts not only is it on 100% of the time but it is also running 100%. Been doing it ever since EC05. EB13 I was getting phenominal battery life.

Im running ICS FB17 with the FB15 modem. Phone runs hot and battery dies fairly quickly. It appears GPS is the culprit.

So just turn off your gps and wireless network location settings. Its not like GPS works so well with this build anyway (at least for most people)
I had the same problem. GPS would lock, but gpsd was at 76% of my battery usage. I went through about 30% of my battery in an hour. Turned of GPS and everything was back to normal.
Awesome thanks,

i had this problem. i turned off gps and it gpsd was still chewing my battery and making my battery hot (the phone shut down because of temperatures). got to the point where it was draining battery even as it was plugged in.
Ya only way i got it to go back to normal after turning gps on was to power off. Even if i turned gps off, it still kept draining battery.

I turned off all possible GPS assist in the location setting and rebooted my phone. It seems to be working properly now.

So I just looked at my battery usage and notices that my phone has been "awake" for such a long time. I know I haven't used it much at all today. Anybody have an idea why this is?
I would upload the screenshot, but its telling me that the file has the wrong extension. ???

I have a huge battery drain (about 60%) by OS Android proccess even in the standby mode. I don't know what to do with this ****. From 100% to 0% it takes about 6 hours my phone dies in standby mode (with CM9 rom), with stock rom my phone lives in standby mode about 2-3 days.
Sounds like you have a rouge app(s). Download Better Battery Stats and CPU Spy. Read their respective threads to understand how to use them. There are threads where people will help you interpret the logs these provide.

I agree with dnorthington. I had the same then I realized that drawfree was draining my battery in a matter of hours...
Android OS only reports such high values in ICS because it includes screen on time.

Did you download better battery stats and CPU spy? Look in the ATT Galaxy S II thread. There's a pretty good known battery drain thread. My idle drain is less than 2% part hour. My deep sleep is over 95% when idle. Has to be a rogue app.

I charged mine and let it sit for 7 hours. With wifi set to always on, I get 11% drain overall, 92% deep sleep and 6% at 192.

Hello all I was wondering if anyone had any suggestions on which kernel helps save the most battery. I am a high school student and by the time I get out at 2:15 my batter is at like 30 or 40 percent (even know I don't get that good of service and shouldn't be using my phone In school anyway lol) but im using the infamous 3.9.2 rom... Any suggestions would be great!
Sent from my SGH-T999 using xda premium
Well to be honest no kernel is gong to be the "best" is more like you need to be conscious what you have on. You have to give more info like what percentage you have brightness on, how often you have data on or gps. Also syncing takes battery away so having those on will take big chunks. Really battery shouldn't be that bad because technically I would guess your not using it as much in school.

I normally have the brightness the lowest it can go. I never have gps on.. I use juice defender to turn off my data when I'm in rooms that get no 4G and im assuming synching is off when my data is off to.

What's your typical usage - the screen on time ?
If it's average use and nothing is wrong, you might want to consider buying either an extra battery or an external battery to charge with. Or an extended battery. Battery battery battery.

use one of the several methods to find out what is using the battery...i use betterbatterystats then i find out whats waking my cpu and go from there...
after that i use titanium to freeze the problem...I do this for several phones and normally can get way better battery life from them
Just make sure you don't freeze something important that's going to cause problems. If it's a app you can always uninstall..I'd your screen time is about 4 to to 6 hours expect like 9 to 10 hours max of battery life. Extended battery will make the phone look bulkier and having a case is a issue. If anything get an external battery possibly with charger too.

Try Lean Kernel its the best for battery life.
I noticed faster battery drain when 4G is enabled. Have any of you installed battery saving software to compensate data connectivity?
When 4G is switched off I easily get more than 2 days worth

Try to combine jedix8 and neak kernel then undervolt a bit you will get great battery I use mine for 8hours on screen time with 4g and still get 30% left
sent from t889 running jedix8
I bought Juice Defender and used it on my Sensation and it screwed up my connection so much I had to reinstall the rom, have never used it again.
I'm using Stock, and don't use any battery saver application; obviously running stock is the reason why battery life is mediocre when data connectivity is continuously on. Don't forget to factor in T-Mobile bloat. The battery drains so quickly that for me, 4% is lost in a matter of 30 minutes. Switch of the 4G and I loose 1% in like 30 minutes when my device in use. That's how I know my battery is functioning normally.
Just got a replacement Epic from Sprint about a day ago. Looks new, probably refurbished. They replaced my old one because it started having some problems along with fast battery drain and inconsistent battery level readings on the device.
So I have my new device along with a new battery from sprint, and I thought all would be well but my new epic and new batter is still draining about 10% every 20 minutes with light use (internet browsing over wifi w/ lowest screen brightness setting). Also, when the phone gets to about 30 or so percent battery life it starts lagging and when I pull the battery or reboot it, the batter meter will read real low (like under 10%) once it powers back up.
I am rooted, I installed The Peoples Rom all according to the instructions from qbking77 on youtube just as I had with my last phone without problem.
I have calibrated the battery twice, and wiped the battery stats in recovery.
I was having these same problems with my last epic which is why I had it replaced. Now I have a new one and new battery and the same problems. How can I fix it?
Also not using GPS, Bluetooth, etc
Just wifi and web

Sounds like an application you are installing is the culprit. Search XDA for "better battery stats" and download/install that application. It will tell you what wakelock is your problem.
Wiping battery stats has been stated to do nothing to benefit the phone/battery/user. It's a placebo. (http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer)

GPS and Bluetooth being enabled is fine. They remain inactive until a process calls that action; such as opening Facebook or Maps.
I don't have many applications installed. I installed the battery app just now, so now what do I do with it? How do I use this information?

Play with the settings in the middle and last drop down menus to pick a duration of time and then toggle the top menu to see what's keeping your phone awake. usually "partial wakelocks".
Also, if you have a virgin install, then you can very well have a battery on its' last leg. We have an old phone, so it is very possible you have an old battery. Yes, even from Sprint.
If you don't see any outliers in BetterBatteryStats, then I'd suggest just spending the $12 or $20 on an Epic 4G Touch battery. That one is a 1800mAh battery, compared to our phone's 1500mAh and fits in our phone.
The only thing that seems to stand out is No or unknown connection (something like that) screen (which is always on lowest setting) and wifi (which I'm mostly connected to indoors) the battery that sprint sent me for the replacement is from the GS2 (that 1800mah that u were talking about)

Here's a screenshot of the battery stats I just took. Its been about 20 minutes since I unplugged that phone, when I unplugged it, it was at 98%... I believe it was at 87% in that pic.

Toggle the "other" drop down menu and select "partial wakelock".
Also, check your time without signal in: settings > battery > cell standby menu on your phone. Anything greater than 3% will be a battery drain.

Things seems normal from the screenshots. Could just be an old or bad battery. You could complain to Sprint about it, 50/50 chance on getting a free replacement.

Also, even if I get another replacement from Sprint, I may still go to Amazon or ebay... can you recommend any sellers or specific batteries... after market or OEM?

The cell standby percentage is, in fact, greater than 3%
hence battery drain.

I got mine off Amazon. I made sure I got an official Samsung battery (1800mAh). You shouldn't have any issues locating a few on there.

Put your phone in airplane mode for 3-5mins, then take it off. Check and see if battery still drains.

The screenshot you posted showed a cell standby percentage of 7%. I'm not sure what to do to fix it because it hasn't happened to me before.

So I pulled out my old battery last night and put it in the phone, and allowed it to charge overnight. This morning I put my phone through its normal use. I've been on my old battery for a little over 30 minutes and have on dropped about 8% in this time. I still feel like that's a lot, but its better than 10% every 20 minutes on the "new" battery they sent. So I'm guessing this would mean it is the battery that sprint sent that's causing the problem?
