[Q] Questions about CyanogenMod, and general battery life

Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?

Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

Yep, I'm on Snap too; must be it.

Another thing; I've got a friend on Stock 2.2 Sense (battery sucking widgets filling the home screen, etc) with 100% brightness and mobile data constantly on and he gets better battery life than me (20+ hours!) What is going on!?!?!

I couldn't believe it either, he had 3G on all day and everything and we barely get any signal at all in class. On for almost 8hrs with more than 70% left. I was at about 53%

[Q] Battery drain: mystery network usage?

I'm running CM6.1 RC2, and the past couple of days I have experienced excessive drain, mainly in the first 50%. I attached a picture of the issue. I went to spare parts battery history to see the network usage, since in the about phone battery usage cell standby was 84% of the battery usage, and under network usage there was just an entry for 0, using the most network. When I clicked on '0' the settings application crashed. Yesterday it dropped 35% in 2.5 hours, before it slowed down. It was ridiculous, never used to have this problem, and the battery is only a couple of weeks old so it has to be software. Today it is at 53% after 7.5 hours, which is pretty decent, but at around 70% I disabled 3g and background data to save some energy for a few hours. Is there any way of figuring out what is causing this, or should I reflash? Could it be a CM6.1 RC2 bug? Anyone else having this issue? Thanks in advance
BTW I have no idea why the dialer was so high in usage I only had like MAYBE 15 minutes total of voice calls in 2 hours. The 0 is what I'm concerned about.

Anyone? Bump? No one else is having the issue? Still happening to me on RC3.

I've been getting that problem too.
I used to have battery life of up to 4 days (Mostly standby), now I'm lucky if I get 1.5 (Same usage).
I went in to spare parts and it crashed for me too.

Battery drain here too since cm 6.1

Well '0' is he system's ID, 0 is root. In the graph the blue is bytes sent, red is bytes received. Have you checked other usage like CPU usage? That might be a better indicator of what's using your battery. Then from there you can start to narrow it down to a specific process or app. I'm using the latest nightly and don't have that issue, never have. I use a bit more battery than I think I should but nothing crazy.
Do you have wifi or bluetooth on? Those drain your battery like no other.

I havent used wifi at all today, unplugged at around 6:30, it's 3:45 now and I'm at 63%, but from around 9:50 to 11:45 and then from 12:20 to 2:20 I had airplane mode enabled since the time without a signal was at 70%, very low signal area. So it seems like for only 4 hours or maybe 5~ of non airplane mode time I should be at above 63%. I only had wifi on for a half an hour today. I'm considering going back to stock for a few days just to see the battery life comparison, and then nandroiding back to CM6.1. I always end up going back to AOSP-based roms in the end. I don't have a data plan on my phone at the moment, getting it today I'm pretty sure, so could all of the blue be from the phone continuously trying to access a website? But other people said they have the same issue and I'm assuming that they have data plans, so that can't be too much related. Hmm.
I also checked cpu usage and such like you suggested, there were a lot of things listed but all but two of them were too small to even have a bar. The two that did have a bar visible were minuscule to put it lightly, so that can't be an issue. Battery use in the about phone area always has cell standby at the top, normally between 40 and 80%. It would seem like there is way too much cell communication going on, moreso than normal. Cell standby stays at the top in even high signal areas, so it's not the signal levels. Kind of stumped here.

Well if the cell is in standby then it's linked to a tower and awaiting activity. Every now and then it 'checks in'. If it's doing that too often then that could seriously drain the battery. You're right though, I'd just switch back. Trouble shooting the exact issue wouldn't be worth the time. Maybe try flashing it again later, could have just been a corrupt download that didn't flash properly.

After conditioning my battery religiously (full to empty with every charge cycle) I am back up to about 15 to 16 hours from full battery to system shut down which is way better than the 10-12 hours I was getting when I first loaded RC2. CR_OTA ROM gave me up to 24-30 hours off of one charge with the exact CPU/2g/3g/wi-fi "routine" as I am using with RC2. Tracked battery usage with System Panel app and RC2 has a steady and even drain pattern ... an even diagonal line down the graph (100% to 0%). Cell standby uses a ridiculous 40% of the battery from full charge! On the stock ROM System Panel app shows plateaus throughout the day when the phone screen is off/sleeping where battery use is virtually non-existent. I'm going to load RC3 today and track the cell standby and battery usage. This time I am not going to use setCPU and just let the ROM run as the CM team designed it to be used and see if anything has changed. I tried this with RC2 and the battery still trended absolutely evenly from 100% to 0%. I can live with a 16 hour battery cycle for the CM ROM because it is very smooth and never has a glitch. The stock ROM is smooth as well but it has some buggy behaviors that I just cannot stand for and it does not run the latest GAPPS.

I've noticed i have exacly the same problem(was actually gonna post it when i found this thread)
Needless to say that on eclair my battery lasted ~48 hours constantly, not its drained in max 24...

The highest I have EVER gotten was 24 hours, and that was on a cm6.1 nightly build, pre RC2. I loaded cr_mod and experienced a HUGE drain. I had airplane mode on, just to test, and it dropped 7% in an hour, in AIRPLANE mode, with no screen on time. I went into spare parts and looked at the usage, and sure enough, "running" was at the top, with 99% of the time spent without sleeping. This has never happened before though, so I can probably attribute that to my modifications. I deleted a few apk's and de-odexed it before I flashed it, and I have a feeling something I did corrupted something else, so I'll flash plain old cr_mod and see where that leaves me. I should probably get back into the habit of full charge/drain every cycle. I used to do that until my battery started lasting longer than I was awake for, so I always had to plug it in at around 15 to 30%. I'll run some more "trials" and see what's going on.
Also, on an unrelated note, I love the stock rom, I always love the sense UI, but I hate HTC_IME compared to the froyo Latin_IME, is there any way at all I could port the froyo Latin_IME to the eclair stock rom?
Edit: also, I flashed dumfuq's OC kernel over cr_mod, could that have been the culprit to the battery drain?

Shouldn't be the culprit. It would drain quicker because of the clock speed but shouldn't be too bad.
Yes Latin_IME should be able to be used with sense. Just delete htc_ime and clicker.apk then install latin_ime and it's corresponding clicker.apk which you can get from various roms'. Btw, clicker is used to calibrate the keyboard so you don't have to install it.
NJAZ, what's the result on using CM6.1 without SetCPU? Big difference or not?

Actually, by process of elimination, the kernel was the issue. I remember hearing about there being a bug in the older dumfuq kernels with something idle being null, I really don't remember but it had something to do with sleeping. I flashed pure CR_mod and then 3.5 dumfuq and I experienced the same issue where it wouldn't sleep. I flashed 4.0, but I think it's too soon to determine whether or not the same issue with sleep is occurring.
I tried doing what you said with LatinIME.apk, I even imported the lib file from /system/lib on CM6.1, but the it was nowhere to be found in the system when I booted. It wasn't under keyboard settings, and HTC_IME was gone. I figured it was an incompatibility between froyo and eclair, since the stock sense rom is eclair and the LatinIME.apk is from a froyo ROM. Do I have to something more than just adb push the apk and lib file? I also tried installing it with a file manager, and no surprise, problem parsing the package. It's a system apk so I didnt expect it to be able to install via a file manager. Do I have to use adb install instead of adb push? I'm wondering if htc IME is so wired into the system that it won't work that way. What if I rename LatinIME.apk to htcime.apk or whatever the name of HTCime is and see if that works, because the system may be is treating that as the stock android keyboard, rather than a third party one, because it is labeled touch input in settings, just like LatinIME in aosp roms.
I'll experiment some more I guess
edit: Nevermind, 4.0 is draining as well, albeit less rapidly. Ah well. I guess I'll have to go back to CM6.1 if I want to do overclock. Shame, I love sense so much.
ANOTHER edit: nevermind, you were right, it isn't the kernel at all. It happens when I turn wifi off. I'm assuming that's because I don't have a data plan so it's continually retrying a server that it can't access. I don't know why it didn't do this on the stock HTC kernel, but I'm pretty sure it's the issue. If I turn wifi AND mobile data connection off, it stays at normal drain as well. Well, I'm at 11% and my battery app is estimating roughly 1 hour and 20 minutes remaining, so I don't know if that's GOOD, but I'll give it a good full charge tonight and run it tomorrow. I hopefully will have data activated tomorrow so I can really test it.

Hey guys new to the slide forum but not new to the site. I come from the G1 thread and we had the similar problem. How is your battery life on a 2.1 ROM? I have my phone rooted with a Sense ROM and it has 2.2 and i do see a bad battery drain as well. I remember froyo ROMs battery life may not be the greatest yet. I remember that was always a big problem over there and it looks like it still hurts here. Have you tried setcpu settings?

Maybe this information will help, i forgot to mention last time i posted that i'm not using a HTC device, i'm using Samsung Galaxy S, and there are more ppl with this problem on our forum aswell, so maybe someone can use this information correctly, i mean, it's either a program that's doing this or some strange freaky froyo process that not everybody has? or idk..

We'll need to get a log or something from one of the phones doing this and see if we can pinpoint the issue. Anyone experiencing this issue using compcache? Maybe it's doing some sort of background compression/decompression or swap is swapping too much while the phone is 'off'. Like I said, we'll need a log dump uploaded so we can sift through it.
As far as the latin_ime, try getting the one from a 2.1 vanilla rom. Check the slide rom bible for the 'senseless' roms like CM5 or something. That should do it.

Well my desire was to get the froyo latinIME onto eclair, since it's prediction engine was so much improved, but I'm getting used to HTC_IME so it doesn't matter.
As for the battery, for me at least, running the cmkernel from dumfuq, v4.0, I get BETTER battery life than the stock HTC kernel. Weird right? If I enable data I get tons of blue in spare parts, under network usage, for things like calendar and contacts. I'll have to assume that's because of the lack of data plan, my data plan doesn't become effective until december 9th. Otherwise, I have no excessive drain. It must be a cm6 issue, with cell polling. Cell standby was always up in the 70%+ range in battery usage in cm6, and on the stock rom it's around 27%. Wi-fi and display are highest, and I still get 20-25 hours.
I agree, to pinpoint the cause of the problem in cm6, someone needs a log to analyze, I'm not actually that smart with these things, nor am I running cm anymore, so can't really help there, but it'd be a good start.

Well I just recently saw this almost exact same issue (maybe not as extreme) on the samsung tablet running Cyanogen. They removed the phone, telephony, mms, and one more .apk to resolve it. This issue was caused by the lack of a use for those .apks but the system was still using them... a lot. It seemed similar but not exact, maybe some of us more tech savvy people can look into those and see if there's an issue.

Yeah that'd be cool. It must have something to do with that, since it's the cell radio sucking battery.

I flashed 6.1.0 stable, battery drain seems to be slightly less. I'm still at around 5 or 10% below where I was at this time on stock, with 9.5 hours off the charger, current level 57%. Although, I did use airplane mode for almost 2 hours, so really I'm like 10 or 20% below where I should be. I just can't figure it out, cell standby is at like 80% usage in this ROM. It's ridiculous, is it the polling intervals or something? How can it be so much less battery efficient than stock?

I flashed 6.1 RC2 with a low battery and had trouble with battery life. TMO's service was acting very strange for a couple of weeks and my cell standby was consuming a lot of juice. Flashed 6.1 RC3 with a well conditioned full battery. At first I used no setCPU just to see how things would go ... 11 hours from full battery to empty. Added setCPU to RC3 and got 27+ hours out of a full charge. Either TMO fixed it's towers or RC3 was better with cell standby because my network usage was not cranking overtime like it had been. Finally, I flashed 6.1 stable with setCPU and I average around 22 to 24 hours on one charge.
One observsation - when I first flashed RC2 I was really into my phone again. I was constantly tweaking it and flipping through options, testing apps, digging new Gapps, etc. ... bottom line I was just using my device waaaaay more than usual and I think that played a huge role in my (supposed) poor battery performance. All seems to be well with 6.1 stable.

stock 2.1 idle drain

So...I'm using 2.1 and for some reason when I'm not even using the phoone..the battery drain is ridiculous. Since I'm new to 2.1, does anyone know what is causing this? Any processes I need to end? Any thing I need to remove?
I'm straight up rooted stock 2.1. No custom roms, just a custom kernel. I only downloaded Pandora, Wordfeud and SetCPU.
Edit: I also wanna add that I leave on 4G as well and I see it idle out and when I turn it off and leave it off I still experience the same amount of drain so I dont think its 4G.
And for more details on the drain...I went to sleep for about 3 hours and during that time I went from 91 to 42.
Edit2: Im gonna actually see if maybe it was just the kernel...I was using the first version of a kernel, not its latest version so Im going to put on the latest. But still, Id liike to know if it was a common problem and how most people fixed it.

Kill the omadrm process with each phone reboot. (Forgot exact name, but that is close) If you aren't always in a 4g area, having that radio always on will drain the battery.

Edit: Also double check your phone standby time and see what percentage your Time Without Signal (TWS) is at. Toggle Airplane mode after each reboot will correct that bug.

Also fyi you can use Tasker to toggle airplane mode for you automatically every boot

Click battery history, then click where it says Other usage, change to Partial wake usage, this should tell you what is using your battery while its asleep.

It you can just.install spare parts and.look. also check your time without signal. If you don't reset your radio its prolly 50%. Whether.that is.cosmetic or actually does cause a battery drain its still good to do.

Battery life even with removing a few apps is pretty bad.
I think the most I got after a week of tests was about 18 hours and that was with almost no use.
Try downloading JuiceDefender from the market. It's free. What it does really is enable/disable your 3G/4G/WiFi connection when your phone is not in use. It also enables it every 15 minutes (default setting) to get email other updates such as weather. I am not kidding when I say went from an 18 hours to 72 hours hours. Granted, that was with little use.
Can download JuicePlotter as well to get an idea of how your battery is dropping and holding.
Side note that WordFeud constantly runs in the background, so that WILL rape your battery. JuiceDefender will keep it in check. Best app I ever got.
For reference, under 2.1 with JuiceDefender I would lose only about 1%/hour at night when I was sleeping.
Under 2.2 it's more like 2% per hour >.> and I've yet to figure out what's draining it.

I thought I'd chime in since the OP mentioned Pandora. After installing Pandora I noticed my battery drain had gotten significantly worse even when properly quitting out of the app. After uninstalling Pandora battery drain has normalized to the way it was before.

Also, setting your network to sprint only helps with battery too.

maybe where you live it does, but thats an awful idea if you are in a town with little service because it will spend more time searching for service because it can't roam (i live in the middle of nowhere in new hampshire).
instead try to update your PRL. download the SDX stock app removal apk. remove the drm crap. and reboot. then charge your phone all the way, reboot into cwm, and reset your battery stats. then let the battery drain all the way and recharge. that should improve it significantly. thats what i did and it worked pretty damn well. battery life is upwards of 36 hours nominal charge now. and my phone used to drain battery WHILE i was charging it if i used it at all. and that was with a 1 Amp charger. also dont let your battery overcharge, mine seems to drain easier when i leave it plugged in all night.

[Q] Cell Standby/Phone Idle battery woes

The battery on my Evo has been plummeting recently. A while ago I could make 36 hours easy, and now I am lucky to get 12. The reason it seems is cell standby/phone idle, according to battery info. Over the course of last night I went from 85% to 28% while I just slept, and according to battery info these two things are responsible for that.
I'm not sure what they are or how to decrease, however. I read that NV and PRI 1.90 was causing problems for a lot of people so I tried downgrading to 1.77 as suggested, but I have no idea where to find the information to see if I successfully downgraded. I am running CM7 nightly build 23, I have wiped battery stats once and I am currently waiting for the phone to die before charging it again, but this has been going on for quite a few days over numerous roms and battery wipes. If I put my phone into airplane mode, the battery is hardly touched overnight. During the day I need my phone on however and the battery drains just as fast, whether I am using it or not.
Any suggestions?
ps. under accounts and sync the only thing I have set to sync is email by push, I receive only a few emails a day and a couple at night so I don't think that would be the problem. Facebook is also set to sync contacts, but only find status updates and the like when I refresh manually. Twitter, and my google account in there but both of those are set to sync manually.

I have never used spare parts in my life so bear with me; but when opening it now all I see is device info including battery history, battery info and usage stats, and general options which all have to do with animations, font size, haptic feedback, or compatability mode. I don't see anything that talks about wake lock in here

You click battery history, then on the first tab, click partial wake lock, and on the second, you can click since last boot.

Android system is by far the winner with almost 11 minutes of usage, email is next at just under 2 minutes, facebook at about 1.5 minutes, and a couple other things (dialer, sms, google voice, google services) all coming in between 5 and 30 seconds.

Hmm...are you in a bad signal area or leave your radios [3G,wifi, 4G] on all the time?

I suppose I have 3g on. I never leave wifi or 4g on and my signal is between -85 and-96, according to battery info my time without signal is 0%

Well you should turn your 3G off when not using it, that'll definitely save your battery.

I will try that in the future, but it still does not explain why I am getting 1/3 the battery life I used to while doing much more to conserve battery. Could it have to do with my pri and prl and such? Maybe I need to update profile and such, like it's not looking for the right towers? I don't know much of anything about how polling and service works.

What's your wake time vs. your up time?
It sounds like you have something staying awake.
Have you gone to menu>setting>About Phone>software information to see if your PRI version & NV have been downgraded?
What kernel are you using?
Are you using RA or Clockmod for recovery?

I'm not sure how to check wake time vs up time, but it would likely be useless right now, as I nandroid backup, flashed a sense rom, updated my prl and profile, checked to make sure i did downgrade pri/nv and then went back to cm7, so any battery info it is going to give me right now will be inaccurate while I wait for it to charge/discharge again over the course of the night. It does still have my previous information though since it was a nandroid backup and I've had it plugged in entirely since then.
I did succesfully downgrade to 1.77 PRI
kernel is savagedzen 0.2.1 cfs havs wimax GB (2.6.37.4)
RA for recovery.
I also uninstalled a few programs including facebook and twitter in case there was anything like that interfering with my services. I still use Go contacts and Go sms however, but I have unchecked any options with them to have facebook integration. If you could tell me how to check up/wake I can check that tomorrow morning when I wake up to see and go against whatever I had. Currently I'm just trying a few things out before tonight to see if anything had helped. An idle phone sitting on my window sill for 8 hours should not drain the battery THAT much, so something is off.

Go back into men>settings>about phone>battery (you can check it now)
If your up time and awake time are the same, you have a program that's stuck in wake. I also use a program called "system panel" that will show me live time which programs are using the most resources. OR you can use "Battery Monitor".
If you have wifi at home I would suggest you set up your phone to connect to wifi and shut your 3g off. I use a program called "Y5-battery saver". It automatically connects me to wifi at home and disconnects and switches to 3g when I'm away from the house.

attached is a screen grab of the graph from battery info
if needed:
cell standby says time on 15h 44m 47s (same as time listed on battery)
phone idle says 14h 46m 58s
(these 2 items used 47% and 44% respectively
thanks for the wifi tip, i used it on sense a lot but with most aosp roms it causes problems unless you set it to never sleep, and i didnt know what that affect it had on battery so i usually just turned it on when necessary or when in a low-signal area like school.

That doesn't seem that bad for ~14hrs on battery.

my problem is that it's while I'm sleeping. I used to get 36 hours of battery before getting to 15% and being told to plug in, and now I used it a little last night, went to bed and woke up to it being at 28% and was told soon after to plug it in. I just dont remember sleeping destroying battery life like that in the past. granted 15 hours isnt that bad, but when 10 of the 15 hours the phone is just sitting there it worries me because if I were to go through a normal day, where I charge it at night and use it during the day, there is just about 0% chance that I'll be able to make it through the day without plugging it in sometime in the middle.

yeah, that's not bad. You're still at 87%? LOL. Maybe I need to switch to AOSP ROM!

I'm Back to 87%, I've been on the charger all day, hence the battery graph raise. the dramatic raise was from when I flashed the sense rom to update my profile/prl. (obviously it wasn't monitoring during that time and when i came back and started monitoring again the battery was much higher)
it actually died after ~15 hours, with 10 of those 15 hours having doing nothing. I got systempanel to see if it gives me any more info and the main reason i use aosp is because of the terrific backlight handling. I like it to be super dim while inside and bright outside, and find on sense roms the auto backlight is too bright under normal conditions. I should be getting much better battery life than this. I'll try again tonight with the battery being monitored to see whats up and I'll try going into airplane mode tomorrow to see what that does at night for comparisons sake. hopefully there is just some program using lots of data that I don't know about. i'd love a quick fix lol

It's almost as if there's an Evo "battery curse"!!!!!! It has been HELL finding a ROM that I love that has great battery life. I really liked Myn's but for some reason I could NEVER find a kernel that would give me great battery life. I'm currently using ultrablakk 3 by King's and love the interface, just trying to find the right kernel myself. I think I'll do a nand and try an AOSP for a change. Vaelpak looks stable. Good luck with the battery life issues!

I'm using an unrevoked-rooted evo and at 10% wake time, it lasts for about 15 hours unplugged. That is why I usually keep it plugged in whenever possible. I have task killer and do not synch anything except for weather and news. I do have 3G running all the time as well. I wouldn't do that if it weren't for the email checks (4 accounts checking every 30 min). If the 3G could be automated to turn on during the checks, that would save more battery life, but I don't know of anything to do that yet.

[Q] S3 Battery Drain after Jelly Bean

So I searched all day for an answer similar to mine and I did not see what I could do.
I was on rooted on ICS until this weekend when I updated to Jelly Bean and rooted again.
My Battery usage was working fine in ICS, what I would call normal battery drain.
After the update I am getting terrible battery use!!!!
I have tried closing, diabling all apps, radios, I have diabled bloatware.
But my battery keeps draining at a rate of 10% and hour!
All this with minor use.
I have opened a few apps and the Play Store but nothing else.
The S3 has just be inJust in standby.
In the settings, under battery it show my main power consumption is the SCREEN at 60%
I dont know how!
When the screen is off, I dont have a video wallaper and when I do power up the screen its so DIM I can hardley see anything.
All this happened after the Jelly Bean update!
Any idea on what I can do?
Do you think a factor restore would help?

Yes, back your dat up first though (contacts, calender, ect.) because you will have to redownload your apps. I did a reset and was on stock after updating but still had terrible battery life. The fix? Take the battery out 40 minutes, put it back in and run it COMPLETELY dead, and recharge it while it's turned off. Make sure you have time to do this without needing the phone because it takes a while. Like 7-8 hours. I've went a day now without much usage at all (still at 90% charge) and have a day left on standby. The battery reset helped more than anything I believe.

Yep same as mine jb update has a heavy battery drain..and my skyvalex callrecorder stopped working..i just flash back to ICS.

My opinion, factory wipe and Re-root it.
Install SetCPU and the Ktoonsez kernal to manage the power settings. Also Go Power Master is a good app to tweak power settings.
In SetCPU you can have it clocked down when the screen it off.

Had the same problem. Called att went through the ranks until I was told by att warranty supervisor that they had no work around and I should root my phone. Shocking they told me that. But I found the problem. I uninstalled the update to Google now and then shut it down. Battery seams to be doing good now.
Got a free battery from att though. I guess cause there higher ups have no idea how to fix drain.

Luckily your type of phone has a removable battery....unlike me...cannot replace to a higher battery capacity

Semi-solved
I somewhat have solved my problem.
What I did was Factory Reset from the Setting menu. I thought I would have lost Root doing this.
It was already set in my mind to just wipe the S3 clean and start over but the root did not get washed out.
So, I used Kies to only restore my contacts.
Instead of having any old apps restored I downloaded them all over again from the Play Store.
So far so good!!
I have better battery life than prior to the reset.
I had been losing 8% and hour in Standby and 10%+ when in use.
So far today I have used the phone with my screen brightness high, made about 10 calls, surfed youtube and I only down 6% in the last 2 hours.
I consider that better.
If there are some things I can add to my diable list that you all know of to give me an EVEN BETTER result please let me know!

Poor battery life here too. Battery settings says screen is eating 78% and Maps eating 10%. I'm a heavy user but its mostly surfing this site and Facebook. I don't play games or watch YouTube much

Does this solve the battery drain issue?
Hiya all.
I haven't got a S3 so I can't confirm this works.....
A friend was having the same battery drain issue and I was going through his settings and noticed that "Sync All" was on.
Turned it off and the battery drain stopped. We think.
It seems to easy to be true. So I'd like more S3 owners to try.

Hi have the lte version that i got couple of days back and i have the same problem. I have not rooted and it came stock with jb. So you have to do a factory reset and remove the battery and try or just the battery?
Also how to remove some stock apps, I don't use any.

My battery life stinks. I had to get the Mophie case with extra battery built in. works great
