I can't shake the Android OS from draining my battery.

I've had this problem once before and it was simply as easy as switching my kernel. You can see here.
Now I've tried GR to CM9 and then to Codename Android Build 4 still had the problem changed Kernels.. Then decided to GR to CM9 and try Beam, and yet again still had Android OS draining the battery. I then flashed the Hefe kernel and NO change.. I've looked around on forums and remember seeing someone mention strange battery stats I can't find it at the moment, but if you look at my stats below you can see that not only is the Android OS draining the battery the graph shows huge drop off points. What exactly are those? Thanks in advance for any help!

That looks like you need a new battery. A couple weeks ago I had the same problem. My usage looked the same as yours where there were sudden drops in the battery percentage. I suspect you have the same problem.

Try or buy Better Battery Stats. There really isn't anything that compares, either for features or support.

Have you tried clearing cache, clearing dalvik cache, then fixing permissions, rebooting and waiting at least ten minutes after reboot? That is what always fixed my "Android OS problem"

Yeah I've tried it all, and now I have replaced my battery and still getting the random huge battery drop offs. Tonight I'm going to GR to CM9 and then to codename and not restoring my apps

I started on stock GB, went to the 1 click stock with root and CW, to CM9, to Remi's ICS. This is what my battery looks like

@getochkn
Yeah, but you were sleeping or doing nothing, phone was idle. LOL Seriously, how is that possible? I have tried many ROMs, today I had a big issue on CM9, battery dropped from 60's% to 1% when phone got stuck and shut down. I had an emergency and needed my phone to call and couldn't. I got very pissed off and now I'm on GB because that battery drain issue has been all over ICS. I have tried calibrating, GR's, I use less apps... nothing! Phone lasted like 4-6 hours with average use. I needed to charge it like 3 times per day. It made my mobile phone, not so mobile.
Not complaining. Just a real issue. I know there are bugs and that development is ongoing. I love ICS but just can't afford to loss so much battery again in another emergency case scenario.
I would be happy to get 12 hours of use. I remember with Redux 1.2 (GB) I got 18-25 hours depending on use. Share some of your usage. I may need to buy a new battery.

Music for about an hour, wifi on most of the time, airdroid'ed into it, messing around with settings, took about a dozen pics.

[Q] battery and cpu problems

Doing a check on wife's atrix2 bc her battery will drain very fast some times and other times not like 3 hours sitting on the table. i downloaded app OS Monitor to see if there was an app sucking the battery down. under message tab the cpu1: shutdown then cpu1:booted secondary processor it keeps repeating that over and over about every 10 seconds. has anyone seen that and is that something that would drain the battery very fast? any help would make my life better thanks

Install supercharged script will increase battery life!

Questions should be posted in the Q&A Section...
Sent from my rooted Mayan Calendar

First of Apex is correct, this should be in Q&A. But since it is asked, we'll try to answer.
A little more info about the phone would be helpful in getting an answer to you. Is your phone root? If so, is it running a custom ROM, and what mods have been done? Is it running ICS or GB?
A good app to find a battery drain is BetterBatteryStats.
I also second the SuperCharged script as a battery saver (in most cases). It is quite easy to setup once you understand how to do it. Also be sure to read all of the first two posts in the thread. You will need to be rooted to run the script.
Hope this helps and hope we can get you squared away.

Seeing as how you have OS Monitor installed to try and track down the cause for the drastic discharge in battery, I have to assume that your wife's Atrix 2 is not rooted, and you are likely on 2.3.6, since the only way you would be on ICS is by obtaining root access and flashing either of the two leaked versions of 4.0.4. That said, we need to know a little about the 'usage' of the battery that is causing the sudden discharge. If you can go and get a screen capture (with another camera phone or otherwise) and post the screen shot of the battery statistics from navigating to Settings or System Settings>Battery>and show what the linear graph can tell us about the usage of the battery. How long has this issue been occurring? If not long, comparatively to the length you've owned the device, I'd rule out hardware issues. Likely, you have a rogue app, or something else like a kernel or power wakelock that is causing constant drastic discharge rates. I've written up a rather extensive guide for getting the most out of your battery (as seen below in my signature), and you can have a look at that to see if any -or all- of those measures are helpful. It sounds like the battery itself could also be the culprit, but again, without further information to go off of, it's so hard to pinpoint...

[Q] Memory leak, battery problems, and screen issues.

First, my phone has a memory leak. Like, after using it for a while, even an hour or two, the available memory will go to 0. I have tried ending all apps that could be suspect, but all of the memory being used that is reported by the settings is much less than what is necessary for there to be <10MB of available memory. I even try to end as many programs as I can, but this eventually happens after some usage. Before you ask, no, I am not using task-killers, and I only notice this and end apps when whatever is leaking is starting. The phone will not effectively end enough applications to free the space. Almost every app will say "restarting" on the "running" page, and none will be seen on the "cached" page. It will result in the phone locking up and rebooting. Also, this happens during high CPU usage (might be a memory issue though), like while updating apps.
Second, my battery life since the OTA has dropped significantly. Now, I am lucky if I get 6-8 hours of battery life while occasionally using the phone and listening to music a lot. The screen seems to be taking most of the power (~65%), and the brightness is regulated by JuiceDefender. I have tried to automatically set it without JD, and it was worse in battery life. It is on much less than the wifi, yet is somehow taking up far more battery. Second place is the Android OS/System/Mediaserver combined (~20%), for whatever reason. I have tried using the Battery Calibration application multiple times and it has not helped. Disabling JD makes battery issues worse. I have looked for wakelocks, but besides the charger, I found none that looked suspicious/non-OS related. See attached file for battery info.
Third, for some reason, the dead pixels came back? Now, it looked like at first there was a shape of a butterfly in spotted dead pixels. Most of those localizations disappeared (or, the "dead" pixels came back to "life"), but a few grew, and now I have somewhere over 100 dead pixels. A few of those have shrunk, but it is still an eyesore. I can provide pictures if it will help. I'm not sure why it is doing this.
Note: all of these issues have started since the ICS OTA. I reflashed the stock OS before doing the OTA.
Any help would be greatly appreciated for any of these!

Yeah mine is like that or worse if I have wifi/screen on as much as you do.

The drain is pretty steady even with minimal usage

Any ideas on what could be causing this?
Sent from my MB865 using xda app-developers app

try FXZ stock ICS
freeze all unneccessary apps ...
dont install any other extra apps (downloadin from market)
try to keep minimum apps..
stay as much on 2G/Wi-Fi
ur battery should last for atleast more than 18 hrs for moderate use (else it will drain dependin on how heavy u use)
if this doesn't work then u'll need expert advice
& remember you'll get rarely above 24 hrs (usage matters a lot)
correct me if m wrong ...

I am also facing the same issues. I have the latest STOCK ICS.
Huge memory leak! Launcher has to restart on every unlock barely 20-7 mbs free!! and battery also drains pretty fast, although not when in sleep.

try "fast reboot"
it will clear some memory

CleanROM 5.5.1 "Android System" usage.

(I don't have permission to post this on the development thread)
I have a Verizon GS3 that I recently flashed CleanROM 5.5.1 onto, it works great and I'm really enjoying it.
Just one quick question: I noticed that my "Android System" has been using a larger percentage of the battery life relative to the unmodded phone. After a whole day of average use, the Screen is took up 28% of the battery, while Android System is in second place with 15-18 % each day usually.
For those that are also running the ROM, what percentage do you guys get for Android System?

That's normal on jellybean for some reason it still gets great battery life. The best combo for me so far iscleanrom 5.5.1 the HE modem and Ziggy's kernel it has awesome standby time too! I also disables Google now since I don't use it much

Since you just flashed give the Rom time to adjust
stripped apart rebuilt with Clean Rom&XdaTechnology!!!

Yea, Give it a break and time. If you use phone Android will be low. If you let it idle it will be high. But if you look usually the actual time on wake is pretty low. Lot of apps using maps and any app that polls uses Android also. Have to look at how they work together. We are seeing when good idle is like 1.5%/hour. Bad is like 3%/hour. ICS was running like 1%/hr but we may or may not have had Google Now. which is a battery hog.

[Q] Upgrade to Jellybean Finally?

I have been sticking to ice cream sandwich as I saw that there were several negative reviews about the jelly bean update specifically regarding battery life. I was wondering whether I should update or stick to ICS. Also I am rooted currently on ICS, what is the best way to update to JB?

Flash a jellybean rom, and the new modems.

Hmm, I was kind of looking for an evaluation of battery life mainly and whether its worth it to actually upgrade since I treasure my battery life, so have they been able to fix the issues with jb?

There are several threads to help with battery life on jb.

Maybe I set up my device differently but I have not noticed any degradation in battery vs tw and this is from a month of consistent use.
I happen to do a similar setup and use all the same apps and I honestly can't tell a dif in day to day battery life. I still get close to or over 6 hrs screen on time on cm10.1 vs beans 14/13 w the stock kernel in a decent signal area on 4glte pi only and no WiFi at all but I use a Samsung OEM extended 3000 mah.

I too was pretty concerned about battery life. After researching, it turns out most battery related issue is centered around Google Now. This turns out to be true. Just turn off Google Now, then go into Maps>Setting>location setting, uncheck everything (especially "report from this device"), and you won't have any battery issue.
Also, install Greenify, and greenify everything that should go into deep sleep mode when you're not using the phone.

Man I couldn't imagine shutting down all the things I use. Only thing I turn off is GPS when I am not using it on tw. On cm10.1 I leave everything on and don't try to save battery...no issues. I do agree with going into maps and turning off location reporting

So , I have decided to upgrade to JB, but Ive forgotten how i should do this. Im rooted currently on ICS, but Im not sure if I have an unlocked bootloader ( how would i check?) .
Can anyone suggest a tutorial as to how I would go about doing this since im rooted.

Why don't you just flash a JB ROM? If you want to factory OTA I would search "how do I unroot my S3."
