A few days ago I decided to try out ktoon's kernel. I was getting horrible battery life and there is a distinct possibility I did not give it enough time to settle as some have said. One person suggested I get Better Battery Stats, but at the paid app part, I didn't bother and went back to stock kernel.
Since then I have found the thread here and installed it to see what was going on. Fully charged battery unplugged and left idle.. When I woke up I had 8 hours of time on the battery and 92% left.. I was happy with this... A quick game of Angry Birds Star Wars later, and I am down to 88%... Now it has been an hour and a few random things later (Angry Birds Seasons, uninstalling bloat via titanium backup) and I am down to 78%.. 10% gone in an hour?
I am just a bit on the very confused side. I was getting 18 hours or so of decently heavy use prior to flashing a custom kernel. Now, I could just be checking my phone more and not noticing it and causing some bias here, but I am at a loss. One member seems to think I have a hardware problem causing my battery drain and that I should replace my device, but I figure it doesn't hurt to seek a second opinion.
As for the ROM I am on, it is just the stock LJ7 with a few theme tweaks I have done and removed some bloat.
Perhaps I am just looking too deep assuming something is wrong..
EDIT: I just followed a tip by Naddict to stop Google Maps from reporting anything.. Hopefully that helps a bit..
Same I think I get good battery life randomly like for instance any ROM or kernel I try I get random battery life sometimes 10+ hours sometimes 7 or less and I do my best at optimizing my phone to save battery I switch brightness to zero no sync at all juice defender ultimate was also tried lol

Could you post kernel alarms. I mentioned the potential for SD issues basically it works this way. You have cached information that doesn't get wiped the program accesses it and basically because for instance the ktoonsez kernel contains newer linaro or the fact it's based on 4.12 those small difference make the cache potentially poisonous.... another example is corruption of the partition causing media scanner to basically endless loop another example network spoofer if it crashes while running corrupts dalvik and requires a wipe. Or your SD card it's failing. Just examples

Forgot to mention, when I wrote the OP, I had already switched back to stock kernel. Phone is plugged in charging atm, I'll have that screen shot for you in the morning if you still need it.
I can't complain with these results here... Since I did a few things when I got up, I lost 1%. But over night I only lost 7%
What am I doing wrong. 4 hours after a full charge and I'm at 28%. I used the phone for a total of an hour today between Facebook, YouTube and Internet browsing. Almost dead, WTF!! Please someone help me fix this. I have each frequency undervolted 115 MHz and its pretty stable. I also keep mobile data always off when not using it. So why is my battery life so horrible.
In using freegs3 jellybean.

I've read a lot of people on here complain about the facebook app just sucking the battery away.. Some choose to use the mobile site to connect.. Try uninstalling facebook and seeing how it goes.

I am having the same issue..this is my first time rooting..and before i rooted I never ran out of battery..but since i rooted i see my battery just droping my the minute as I use my phone..I dont understand what is going on..I tried freezing tons of apps and I have not used face book..any one please help
Do you have better battery stats? It will show if anything is running when screen is off then you can at least narrow it down. What Rom are you on?

Hey everyone, I've tried posting this in the battery life thread but I've gotten no help in resolving this issue. This morning I unplugged the phone from the charger(I leave it plugged in overnight) and the phone dropped 20 perecent of the battery in under 15 minutes. At this point the only thing i was doing with the phone was checking a text message I had recieved.
I have optimized my phone so that I it only updates email and many other services manually but regardless a 20 percent drop in 15 minutes is not acceptable. I have calibrated my battery using the battery calibration app which hasn't worked. I have rooted my phone and am currently using the stock bell rom. Additionally, I am also using nova launcher on my phone and that is about it. The only strange thing that I've done to my phone is use a blackberry charger to charge my battery but I don't think this is the issue.
At this point I am beyond frustrated with this device need a solution now or I'll have to take it in to get fixed. Does granting root access void my warrenty? Do I need to unroot before I go to bell. I will post images of my phone stats in the next post.
thank you in advance for your help.

Before you send it in or take it somewhere, download" Better Battery Stats" and see if you can target where the drain is coming from. And yes, you will need to return to stock but before you do you will need to run the triangle away app. That will reduce your flash counter to 0. I'm betting you will be able to find out the problem with Better Battery Stats though. Check your PM's. I sent you something helpful that I didn't wanna post on here.

*Edit* - Never mind. I see them. Also, what ROM & kernel are you using? Are you using the original charger & cable that came with your phone? I read of a guy having a similar problem & it turned out to be his charger & charging cable.

I don't know what Kernel I'm using but I am using the stock Jellybean rom. I've basically just given myself root access and installed the latest stock firmware. I am using my original charger(plugged into the wall) and last night i left my phone plugged in for over 8 hours so its definitely getting a full charge.
When I was am girlfriends house I used her dads blackberry charger to charge my phone but I don't think that would have wrecked the battery in such a way. I have noticed that the battery seems to draing very rapidly up until about 75% at which point battery consumption returns to normal. I can try charging my phone whilst plugged into my pc if you think that maybe make a difference.

Ok. I gotcha. The charger thing only matters if you use the wrong charger all the time. It doesn't charge it properly. It doesn't do any permanent damage that I know of. I would advise using the Samsung charger whenever possible. Anyways, let your battery drain all the way down to 0 til the phone shuts itself off then charge it all the way back to %100 without taking it off the charger. This should recalibrate your battery. It just got knocked outta wack. It happens sometimes. Let me know if this works. And by the way, you're probably running the stock kernel. You can always get that info by going to settings/about device. Let me know if this helped.

How much screen on time did you have when you were at %68? How bright was your screen? There are a lot of variables to take into consideration. Were you playing games?

I have a friend who had the same problem, he had to get his phone turned in because his motherboard was malfunctioning.
He ended up getting a full phone replacement and hasn't had the problem since.
If you continue to have this issue I'd definitely get it looked at by your providers retail location.
edit: If you root you will want to avoid tripping the flash counter, which from what I've seen lately is very difficult.
Telus flat out told me in the store that they don't even care if it's rommed and have asked me what I like to use for roms etc which is nice, I don't know if Bell is as lenient.
Best of luck.

The previously mentioned %68 after 5 hours is pretty typical of what I get running stock kernel with ParanoidKANGdroid 1.40. That's while I'm at work, so I'm usually connected to WiFi, on silent, with most of my usage during that time being texting, but I do usually play games on my lunch. I have thought that was a bit excessive drain, so yesterday I set up CPU Editor and set my maximum CPU frequency to 702 MHz. I got pretty close to the same drain.
Today so far, I have the stats uploaded, and that seems much better to me so far.

Thanks for posting this thread, I'm having the exact same problem. It's been an interesting go for me.
Some times it does it and other times it doesn't.
I'm using cyanogenmod nightly from 1.3.13 with the latest ktoonez kernel and I've noticed that today, it's sucking battery more than ever. I'll attach a screenshot, but I think there might be something with the charger as mentioned earlier in the thread. When I charge it at night, I'm charging it off an old blackberry micro usb cable with a generic AC to usb plug.
I'm going to let this thing drain out and die and charge it back up to 100% and see if that works for me.
Does kernel make a big difference for battery life? For that matter, what are the main advantages of different kernels?

It definitely helped me. The main advantages that I see with running the kernel that I use is the ability to undervolt & overclock it. This will allow you to run the same frequency that you normally would but at a lower voltage therefore reducing heat & battery consumption. Google it & do some reading & educate yourself on it before you make your decision. I am glad that I decided to do it.

AOKP allows you to change those settings doesn't it? Or only with a custom kernel?

Yes I think AOKP will allow you to change some settings around. It will allow you to set you min/max clock speed & your gov & scheduler. A custom kernel will give you different gov, schedulers, & different min/max speeds. I use Ktoonsez's kernel & it comes packaged with an app called Ktweaker. He advises to use this app to control your kernel settings. I don't think that they will apply properly if you don't. Also you can undervolt with Ktweaker.

I can't possibly be the first one to create a thread about this. Yet I have been searching and can't find it. So here I go.
I obviously have a T-mobile GS3 T-999. I was on stock unrooted 4.1.1 just fine with great battery life. I updated to 4.1.2 stock unrooted and now my battery life is terrible. I can't even come close to lasting all day like I could before. My habits haven't changed. I haven't installed anything else since they update. I have rebooted and power cycled several times, no change.
Anyone else have a reduction in battery life since upgrading to 4.1.2? Is there anything I can do without going beyond the usual? I have been using power save mode since I bought the phone. So it was that way before and after the update.
Rooting and flashing a custom Rom will increase battery life tremendously. If you don't want to root then disable all the bloat ware. This will speed up phone and increase battery.

Haven't been able to get awesome battery life on my end either. Played with all kernels available even going backwards to kernels I know gave good life on 4.1.1... Something internal is causing it, it seems. I don't get wake locks that I don't cause my self, just battery drops faster now compared to what it did before.
Sent from my SGH-T999 using xda premium
I suspect that the premium suite, which added multi window and a bunch of new apps and features, is probably causing the increased battery usage. With the increasing amount of bloat Samsung is stuffing into their ROMs, decreased battery life is expected.
The life on 4.1.2 is terrible over all not sure why best bet would be routing flashing a custom rom or you could try playing with kernels but those are tricky business. I feel 4.1.1 Roms get the best battery though I'm on 4.2 and not very good battery life on that either
Sent from my SGH-T999 using xda app-developers app
I flashed a number of 4.1.2 roms and found out that for some reason the cpu stays at the max clock constantly. No clue why.. Maybe that's the issue?
Doesn't matter to me at the end since I got a lemon
Yeah I'm not really liking it much. I would do better on 4.1.1
These are my results on Stockorama v2. Stock Kernel.
I don't think it's that bad but I wish it was better.

That's terrible on both accounts lol. I usually get 18 hours with that battery time. I remove all the bloat I mean all of it. I have maybe 20 apps total in my app drawer, I disable all the sync besides contacts, gmail, and calender. But still have drain. On stock kernel it was bad and deep sleep was hardly achieved with no apps running in the back ground. I'm gonna Odin root66 md5, tomorrow and see if it helps. Other then that I'm going back to 4.1.1. I'll report back tomorrow or Friday with results.

Well, I don't plan on rooting or using a custom rom any time soon. But I am hoping to find out what I can tweak to get my battery life back to what it was. I am guessing I don't have the option to go back to 4.1.2 using Kies. And I hear that 4.2 has poor battery life as well, so now I don't have that to look forward too either.
I'm on Stockorama V1 and still had 50% battery when I went to bed this morning (I work nights). The first day after I flashed it the battery was pretty bad, mostly due to wake locks from the Media Server, but that was an easy fix with an app from the Market. I would actually say my battery life is a little bit better now than it was on 4.1.1.

I don't know if Sammy ever solved it, but iwith past updates the media scanner would hang up and drain batteries quick. Some had their phones heat up.
Another culprit can be that when going to a different android version, it may handle some data differently, causing hang ups when it runs into something they didn't plan for.
In either of these cases, its best to do a full wipe (backup first) and then reinstall your apps. Don't restore them from backup as that's just like not wiping in the first place.
Then wherever possible, import your data through the app itself. Not many do this but some do. Contacts is one.
I know it can be a pain, but it can help a lot. Plus you wind up cleaning out stuff you don't use or need anymore.
I always wipe data when updating , unless its to the same android version (4.1.1 to 4.1.1). Going to 4.1.2 shouldn't be to big a deal, but you never know.
Another thing to try:
If you verify media server/scanner is a oroblem, copy all your music, pics, vids, etc to your computer and wioe it from the phone. Then reboot and wait a few min to see if its acting ok. Then copy your files back, wait a few min and reboot again. Hopefully it'll calm down after this.
Hope that's more helpful than confusing!

You wonder why carriers take so long to release an update because usually people would start complaining. It's not 4.1 so don't expect the same thing, usually when there's an update things are the never the same. It was the same thing the jump from ics to jelly bean, when creating voltages for batteries I don't think companies anticipate all the extra stuff a update can bring this is still kinda of an ics phone.

I was able to get 32 hours on average with CM 10.1 and KTunez kernel. I recently switched to the Stock latest TW and I'm seeing 22-24 hours with the KTunez kernel. I am rooted and removed all the bloatware.
I'm running stock rooted for now. I hardly have even noticed any battery drain on my phone. Stock Battery, nothing really battery-heavy, no customer kernels. However I dont really see the use of this Sidebar thing. Its like
HAY GUIZ LETS PUT THE UBUNTU UNITY BAR ON ANDROID HUEHUEHUEHUE SO CLEVER!
But in all seriousness, I seem to be running just fine. So I cant really vouch for Multiwindow being the culprit. I may run some tests though.
I don't remember what it was before. But usually by the time I went to bed, it was in the 40's and sometimes the 30's if it was a heavy day for me. Now it drops into the teens.
I see that as of today, the phone has been discharging for just under 4 hours and is already at 88%. And I haven't even used the phone in any way today before checking it right now. Shows "Google Services" as 41% of the battery use. But that only shows CPU total at 33 seconds. Next item is "Device Idle" at 15%. So I don't understand why it's down to 87% in 4 hours of basically doing nothing.
Though I don't think that info alone means anything to me right now as I don't recall what that info was like on 4.1.1, only that my battery % by bedtime is significantly lower than when on 4.1.1
I was just curious how many other Tmobile people experienced the same thing when going from 4.1.1 to 4.1.2. All stock that is.
I don't have time to deal with wiping the phone clean and starting over. But I may try that someday. My phone never gets hot and I never see the CPU getting much use at any given time.
I do wonder about facebook though. I think it also did an update of it's own around the same time I did the 4.1.2 update. I will check into that.
I have found battery life to be about the same, at first it wasn't that great but now I was able to get over 2 days with minimal use 4g on all day. With normal I use I still get better battery life that 4.1.1

Well when I first updated it was stock and battery life didn't seem very good but I've since flashed a custom rom and all is well. Also I think stock rom got better battery with use, maybe had to settle in? But within 3 days of using 4.1.2 my battery was back to normal again.
I'm having a huge problem with my S3 heating up at the bottom of the phone, right around the sim card slot. I've tried CM10.1 and other similar ROMs and TW ROMs and I'm still getting this problem. My phone hasn't been through any trauma at all and this just happened from one day to another and I find that extremely strange.
Also kind of worried about things melting down on the inside, even tho I know it might not happen.
Can anyone out there help or point me to the right direction.

Are you using your phone and charging it constantly while this occurs? If it is happening while dormant on all roms, might be a specific app or the phone itself is giving up? Not too sure to be honest without more info.
130 degrees?! Where are you getting this info from? I can't even TOUCH mine when it hits 105 and it has an Incipio case on it! At 130 I'd be worried about the battery exploding to be honest.
Have you tried running an "empty" ROM on it? Just a basic ROM with nothing installed?

Crazy part is that it's not the battery that's getting hot. Its that plastic cover right under where the SD card and sim sit. I used a friends infrared thermometer and the highest is 132 but it averages 120-125. And today I used a "empty" ROM and just ran the browser for instagram and some Facebook, about 15 minutes in it got extremely hot. Also tried TW ROM "empty"

Sounds like a phone on the way out... Although I've never used an infrared thermometer on my phone I'm sure its not heating up to those crazy temperatures. When I use it heavily it gets warm but doesn't really ever get too hot unless I turn the screen brightness all the way up, then the screen gets hot.
I know of the area that you're speaking of - I'd consider replacing the device.

wow! this was happening to my phone during the first month after purchased. It was completely stock. i would get a message saying my phone was in critical temp levels. all i did was wiped it clean and started fresh. after that everything was fine.
seems like your problem is much worse. return your phone back to stock and tell samsung to give you a new one. this is very dangerous. especially if it sits next to your leg all day!
@mt3g @EtherealRemnant do you think it could be the radio working harder than it should?

Put it in airplane mode and see what happens. Anything is possible but if it's the radio causing the issue you need a new phone

Crap now that I think about it, that won't help since the phone gets cool when not in use, and the phone is basically useless when without data

Get an offline game that you can play for 30 or 40 minutes... Anything to get the processor up with the radio off.

@EtherealRemnant so I tried it for a few hours and phone didn't heat up at all. I ended up going back to complete stock for an hour with use. Then rooted and flashed CM10.1 and now phone temp is back to normal. Thanks for the help, at least I now know it was a radio problem.

I've run CM10.1 RC4,5, and Many Nightlies, as well as Stock Deodexed and whatnot, with many different kernels (Ktoonz, Stock CM, etc), and I have an Otterbox Defender (And tonight will be an Otterbox Armor). I live in Utah, so we get some fairly warm temperatures and whatnot. My phone never heats up above about 50-60 degrees. I mean i never expose it to heat or sunlight that much, but I cant see a phone getting 130 degrees.

Yea it was pretty crazy how hot it was getting....I actually ended up finding out it had something to do with the MD5 firmware. Now I'm running the old LJC firmware and everything is back to normal.

There is something going on with my phone, Samsung Galaxy S3, V4.3 where occasionally, lately it has been once a day the power draw from the battery will spike as high as 2,000ma (2 amps). This last long enough to drop the charge 10 - 20% and creates excessive battery heat. It happens on charge or off charge. I have tried viewing the running processes with System Tuner and nothing shows up in the list using an excessive amount of CPU. Better Battery Staus also doesn't pinpoint the problem. I have most everything Greenified accept Google stuff of course and useful stuff like email, etc. I now believe it could be connected with GPS since I turned off the GPS I have not had another event other than a 800ma spikes that quickly go away. Need more time to confirm it is GPS related. Are there any programs that will log which applications are using GPS? Any other ideas what could be the problem? I don't understand why System Tuner doesn't show me which process is eating the battery? Can anyone point me in the right direction.
I thonk it may be the radio itself. I have recently noticed similar issues on mine but its usually when streaming videos. I rarely use gps so i cant speak on that right now.
If i have it plugged in while doing this, it gets hot enough to trigger a shutdown due to thermal event....it crashes!

Same here, I also noticed with System Tuner that several applications that normally use 1% or less of CPU seem to spike to 8 - 30%. This all seem very odd. Now I am wondering if the background radio steals CPU cycles and leaves no time for normal applications. Anyway, the issues are reduced with GPS off although the battery does get warm sometimes without any reason I can fine. I'll try streaming audio and see if it triggers.
I would be willing to try a different radio. My current software is Model Number SGH-T999, Android version 4.3, BaseBand version T999UVUENC2, Kernel 3.0.31-1962493, Build number JSS15J.T999UVUENC2.
Unfortunately, no other radio will work. You can try one just to be sure about it. It wont brick, but just wont function. Youll have unknown imei and baseband until you flash the NC2 modem back.
Im currently running my port of S3Rx 4.0, but ill flash back to NC2 in a couple if days to test more on mine. Im also using a case/housing not meant for the T999 so theres a good chance that is contributing to my problems though.

Okay, thank you for the replies. Please stop by if you learn anything new. Velis Auto Brightness is up to 64% CPU usage, grrr. I posted on developers forum maybe troubleshooting that will lead to a fix. The 2 amp spikes haven't occurred since I disabled GPS, so I am guess you are correct about the radio.
The problem returned so turning off GPS isn't a complete fix, seems to reduce the frequency is all. It looks like Android System is the problem. If I shut down pull the battery reboot the bad behaviour continues, only fix seems to wait it out. My next phone most likely will not be a sammy.
Im not really sure what to suggest at this point. I can say that what we are experiencing isnt typical though.
Out of curiosity, have you given any of the ported kk roms a try? I think my Sprint port is probably the most stable/bug free, but they are all good and ive had pretty good battery on each one compared stock. (Ive always had good battery life even on stock though, aside from a few recent issues that I believe are more my own fault). TMS3KK is a solid rom with very few issues. S3Rx 4.0 is as well, but ill be posting an update to it hopefully later today, so I cant say its really been thoroughly vetted yet. Still worth a look though, imo.

No time to try a different ROM yet. I should have time the weekend after next. Thank you for all your suggestions.
I tried replacing the battery. After the first charge the phone lasted for 2 days before the battery dropped to 5%. It took 6 hours to charge back to 100%. No problems until later, it seems to dislike being unplugged moved to a new location and plugged in again. This appears to be when the problem occurs. I usually just leave the phone plugged in all the time. I'll test further with the power before I make up my mind. I think this will be the last Sammy phone for me?
Is it a non stock battery? I've always had issues with those reporting correctly.

Usually I would buy a non stock battery however since this phone lays next to me in bed to wake me in the mornings I am a little concerned with a fire so it is a Samsung battery from Samsung. Leaving it unplugged for a bit and plugging it back in didn't work stop the battery drain. There are no processes eating the battery according to System Tuner so got to change the ROM.
Should I try a ROM first or kernel or both? Could it be an Xposed module, thinking about turning all of those hacks off?
I just remembered, this only happens if the screen is on and the phone is plugged into the charger. And rebooting doesn't clear the problem.
I would start with a stock based ROM. If it were me I'd go full stock rooted. But yeah I'd ditch xposed for now. You might even try reflashing your current ROM, factory resetting and this time don't use any exposed mods. If it still has problems, then try a different ROM.
It wouldn't surprise me at all to find xposed was the culprit. Its really cool, and the dev is amazing, but I prefer not to use it at all. IMO, it's much better to have the mods coded into the ROM itself.

Thank you Doc, will do so and report back here the results.
My phone does the same thing now. My phone never did this when I first got it a couple years ago. I use GPS a lot because son plays on a travel hockey team. I could drive 3 - 4 hours away with the phone on and plugged in using the GPS without any issues. Now, my phone gets so hot in about an hour of the same type of use and it shuts down.
I thought that maybe there was something wrong with the phone because of age but now I see it could be something different.
It very well could be age related, or it could be partially due to that too. But I'd do as I suggested above and run stock for a bit to test. If on a custom rom, and especially kernel, you could run into issues like that too.
If you have the same problem on stock, (and you're sure its not an app acting up), there's a very good possibility that its more of a hardware related issue.

And it is not the battery. I can't load stock until next weekend, need my phone for work.
You can always use better battery stats to investigate while you use it normally. Let it log all wakelocks, including kernel wakelocks for a full cycle.

Tried that, been there, odd thing is nothing shows there. I'm gonna reload with stock per your suggestion next weekend and if that doesn't work I'll try a custom kernel.
Try remove greenify app and see what happens. Cuz with my case the latest version (2.4.x.x) of greenify driving my phone nuts. That app used to be great.
I'm back. Loaded stock 4.3 ROM / kernel, radio is at newest versions, I am going to say the problem is gone. The battery heats up to about 32-33 degrees Celsius however the phone isn't hot like it is burning up so I believe the problem is like Doc suggested earlier with the radio. Which would explain why the process monitors never see any rouge application using to much CPU. So after some pondering, this doesn't stop a rouge application from using to much bandwidth and cooking the radio so to type. If I had to pin it down I am going to suggest it maybe one of these two applications: FCC speedtest and or Opensignal or some other application. Both of the listed applications periodically test the network bandwidth and report back to a central server. I suspect that this maybe trigger the heat problem from the extend radio usage. No proof at this time just conjecture.
I am considering jumping to an AOSP ROM to be free of the Samsung bloat, NOT CM, don't care for CM, does anyone have any good suggestions to try?
