How i got rid of battery drain...

While I own an international unlocked version of the S2, i assume the Sprint version must be very similar. After countless hours of trying to figure it out, this is what i discovered and solved my battery draining issue (it's been two months with no problems at all) i get 4 to 5 hrs display time and it lasts me all day. I was on stock 2.3.3 and recently upgraded to 2.3.4. with same results. The following tips are things i did prior to rooting, and they solved my battery drain issue.
1. Anything that tracks location is a battery drainer and i discovered that i was using wireless networks for location (it's also not that accurate) and it was the biggest culprit, so i disabled it and now i use gps (more accurate) as needed and turn it off when done. If you use Google maps with google latitude enabled, sign out of latitude when done using it.
2. App killers use more battery than saving it by closing apps and processes that run in backgroung that will automatically open right back again. Stay away from them.
3. Some apps if left in memory will constantly cause cpu spikes (suspend and events/0), in my case it was Facebook and Xfinity apps. So i close all active apps in task manager. Don't really clear ram, just close active apps.
4. Use Watchdog from Market to track any apps that might be using a lot of cpu.
5.Enabling Back up my data also drained my battery, so i disable it.
Hopes this helps...

While I can't state for certain that it's causing any extra battery drain, Carrier IQ is hooking into the location service, and every time your location changes, grokking your latitude, longitude, accuracy, and a timestamp. This is new to the Epic Touch.

I constantly have alerts for suspend and event/0 in watchdog. In the stock task manager there really isnt much running to kill. It's driving me nuts. haha My battery life isnt horrible but I think it could be better..

Phone always awake :( What's wrong?

Wondering if i am suffering from the volume bug See...
Charging overnight: http://i44.tinypic.com/9930j7.jpg - Yet my phone has been "awake"?!
After 2 hours: http://i41.tinypic.com/2dim6me.jpg - Discharge almost 20% already and you see the awake time?
After 4 hours: http://i43.tinypic.com/302tok0.jpg - Faint! 50% was drained in 4 hours!
My homescreen: http://i44.tinypic.com/260e6tx.jpg - You will say is my Beautiful Widget, but I removed it and still phone awake!
How can I troubleshoot?

Exchange Services is really high. You probably have a corporate account that is having sync issues, and keeps waking the device.

Yeah I do have a corporate email account. But it's set to push notifications should I receive any e-mail.

Run BetterBatteryStats to see what keeps it awake. There's no reason why Exchange services should be that much of your battery.

Any settings I should take note of or set? What does blue/red bar means per app?

I think it is pretty obvious just by looking at your 2nd screenshot.

If u don't use Bluetooth (if ur rooted) , go to /system/bin and delete the file "bluetoothd" to fix wakelock
Edit: be sure to backup the file first

Yeah pretty sure it was the Corporate Email. I have since then remove the account and this is my result overnight from 100% downwards after 6 hours. VEry good results.
Thanks for your help.

My Exchange went nuts just like that, clearing the app cache didn't help but reflashing my rom over top again did, just cleared cache and flashed rom again and its back to normal, using 4% of battery or so on push...

Congrats on resolving your issue. Just to help others, is there any chance you know and could mention what o/s or version of exchange your work server is running? Exchange and/or the stock email app seems to be a problem for some but not for others. More info might just help someone isolate the root cause someday.

I did not flash. I just delete my account and readd it and it was fine after that.

Google maps draining my entire battery

Since about a week the battery life of my one X has become terrible. According to the battery usage screen, google maps seems to be draining all the juice. Im not actually using gm though, so something must be going on in the background.

Does this sound familiar to anyone and is there a solution to the problem?
Thanks in advance!

Just disable it

And how do I do that? I can close the process, but it will automatically go back on. Disabling the app itself is not something I know how to do and not really something I would like to do either.
Perhaps one other thing of importance: when I open maps (or now) it says location services are turned off, while they are not.

disable from settings app manager OR
get greenify from playstore and just greenify it
problem solved :good:

Also, where do you live at? Might be your not connected to the right sattelites for your region. You could go to play store and download faster fix and make sure your phone is reading off the right satellites.

That's not normal. Whatever wakelock is keeping it awake is not captured in your WLD screenshot. Track it down in better battery stats instead, using "partial wakelocks"

Thank you...that's what I thought... I don't know what happened...so I went into partial wakelocks and everything looks like low %... But kernel wakelocks there was a lot of high percentages...

First thing that sticks out is drop box. It shouldnt be running for that long. Did you turn on auto backup? This will cause huge drains. If turned on turn it off. Also check in service running for 21 minutes... Turn off your gps. This is Google now constantly running and locating you to try and provide you with what it thinks is useful cards (weather, traffic, food in your area) I only then on my gps when I'm gonna use navigation. Otherwise all apps with gps access will start to run and kill your battery. Also I suggest greenify. It'll help a lot with things like Facebook, Twitter, Google search, ect. Wakelocks. Also removing or freezing bloatware helps tremendously with battery drain. And last carrier iq. Something that always runs in the background. Google search it or read up in the battery threads here on XDA. They talk about it a lot and how to try and stop it. Also this thread

although for the SGS5 it can be applied to our device as well

Battery drain extremely quick

Hello everyone,
I have noticed an absurd drop of the battery level when I'm using my device for usual applications such as Facebook, YouTube, etc...
When it's on 20% approx the battery reaches zero level in less than 10 minutes. This problem started when I have updated my device to the last firmware available (14.6.a.1.236)
I have re flashed the firmware 2 times via flashtool and the results are the same.
It could be an software or a hardware issue?
Thank you for your help :fingers-crossed:

Thank you very much!
My device has 13 months of use.
I use greenify in root mode, but don't have xposed.
I have used a calibration battery app and still have this problem.
May I use xposed in stock ROM without the risk of bricking my device?

Chances are it's a hardware issue and replacing your battery could fix it:
http://forum.xda-developers.com/son...ttery-reporting-phone-dying-suddenly-t3095120
I had the issue where my battery would drop from >70% to 0% suddenly, and replacing my battery has fixed it completely.

Test disabling "Google Services", "Google Play" and "Get More" in accessibility settings. Also test disabling temporarly the Google Account "Search for threaths on the mobile" feature. I was having quite fast battery drain until I did this. It nearly takes twice as long time for each percent to go down. As for your sudden drop check if you got apps that could interfere. Apps that can modify the battery stats.
Btw I had same sudden drop of 5, 10 and even once 30% when screen was off. I thought it was the battery and it was like that for some months until I uninstalled official Facebook app. Now I dont know if the Facebook app was the reason or only reason but after that it has worked flawless for months and continues to.

I tried everything and the results are the same ?.
I think my battery is damaged. Right now my device is plugged to the charger. After 20 minutes of being connected, my device shows only 7%
