Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Latest SiyahKernel with stock rooted ICS 4.0.3.
Now, this has happened twice in the last week. I unplug the phone from my charger and place it under my pillow for the alarm to wake me up, and go to sleep. I disable both data and wifi so that twitter won't update and wake me up prematurely. Then, I oversleep about two hours, and what wakes me up is the phone that's EXTREMELY hot. The alarm doesn't go off and the battery is completely drained.
I have no idea what drained the battery and why the phone was that hot (I couldn't hold the phone for more than two seconds before I started experiencing pain). I've tried searching, but there were no topics like this one. So does anyone know how I can fix this?

Thanks for the answer, but even after doing everything there I have the same problem.
A few days ago, I was able to "intercept" the process.
I had just used the phone, and put it away. Then after no more than ten minutes, I noticed it getting extremely hot. When I tried unlocking the screen, the phone had frozen, so I had to pull out the battery to turn it off. When I put the battery back in again and turned it on, the battery level was down from around 80% to around 60%. The battery graph showed like vertical drop, so it was clear that it had happened within those 10 minutes.
Is there really noone who has had this problem before?

Try N.E.A.K ICS kernel. I had some really good results with aokp rom. It's compatible with Samsung rom as well I think. Check it out
Sent from my GT-I9100 using Tapatalk 2 Beta-5
I'd be more worried about it setting my pillow alight
Steps.you could try:
- Wipe all data (Optional maybe an app conflicting with something)
- Update kernel or change rom to CM9 or any other stock
- If none of those work try an different battery
*I believe its an well wakelock had this when i was using siyah 3.1 Rc 1-5*
~Blizz™;
I had roughly the same problem. I did a full wipe and installed a custom from and changed the kernel... everything works perfect then. One of my friends finds taking his battery out every few days works best. Try both and see what results you get.

I would have to guess that it's either the kernel or the battery calibration. Are you using a third party battery? I think with the original samsung batteries, this must not be as much of a problem (I have never owned an original samsung battery for my S2, sadly). I know that with my fake Chinese super-cheap "2150mah" battery, which somehow is small enough to fit in the original cover which makes me think it's more like 1350mah, I have gotten horrible battery drain problems for basically no reason. But, after following the thread where it was explained to charge to 100% and then take the battery out, wait three minutes, and put it back in, I've had the phone stay at 100% for over four hours, with wifi, syncing, and all that turned on.
I should mention that I sometimes also have had this problem where it seems to be charged, then for some reason it drops to 20%.
If your battery is third party, make sure you calibrate it. I've also noticed that the more roms I flash, the worse my battery life is, so I'm trying to resist the temptation of flashing something new every twenty minutes.
Good luck.

Use it.
You could try downloading Better Battery Stats and hope to identify the wakelock or app that's draining the battery. If it's not either of those and you haven't always had an issue with it under your pillow, I'd say it's time to try a wipe and new rom and if the problem persists even after that...hardware problem.
Have you been able to leave it under the pillow previously? Part of me is wondering if the overheating itself is affecting the battery and causing it to degrade though I doubt it should happen so quickly and in such an odd fashion as you're experiencing.
After a bit more tinkering and testing, I'm almost 100% certain that it's the kernel, as it was the only thing "constant" in my testing. I reflashed over and over. I also think it has something to do with the wifi, since when wifi's off, my phone is fine and doesn't get touched by the described bug. So right now, I'm waiting for SiyahKernel 3.1 to be released while keeping wifi off.
On the changelog for RC6, it says that the "battery drain issue" is fixed, and on the changelog for 3.1, it says "new wifi drivers", so I'm assuming it'll be ok once the 3.1 is released. Thanks for all your replies and help.

Can anyone help me with this problem here?
I have been trying various roms on my Vibrant, but didn't spend a ton of time on the ones before Paranoid Android because they seemed unstable. So I can't fully tell you if I was having this issue before, but I will say that the battery drain didn't seem as extreme.
I noticed that I was having extreme battery drain the night after I flashed PA (it was plugged in overnight). I was trying to charge it before I went out, and here's something weird - I was talking on the phone plugged into *AC* power (NOT usb!) and the battery drained during the call! That kind of threw me because it's never something that's happened on AC for me. By the time I went outside, it was down to almost nothing, drained about 5% in 3 minutes walking to the bus stop and died. I recharged it again, swapped in my extra battery in case it was a battery problem, and noticed that also it took a couple of hours of basically not using the phone to drain to 0. I have no signal issues in my area.
I noticed that in BBS that a wakelock ste-gps-interface was taking up a TON of time. I am not using GPS that much. I figured it may be Google now, so I actually froze the app. That didn't seem to help, so I turned of Google location services as much as I could to still use maps - basically everything short of turning GPS off itself. I still got the wakelock! This shows up in the battery settings as making "Android OS" jump to 50% when this is happening.
So since whatever is triggering this wakelock causes the phone to not go into deep sleep and idle at 100mhz, I'm getting bad battery drain. I tried several things such as updating the Semaphore kernel, reflashing the GPS data, using an AGPS app to reset the cache, and tweaking the CPU governor/IO settings. For some reason I seemed to get some relief after reflashing the GPS data once and then clearing cache/dalvik cache, but the issue has come back again.
I couldn't find any informative posts on it, but interesting the posts that I did find were Vibrant specific. If anyone has any ideas past turning GPS off completely please let me know. One thing I have not tried is kernels other than Semaphore, but I've heard that Semaphore is a good match with PA. Thanks!
Edit: I may be wrong because this seems odd, but even turning the GPS off in location preferences doesn't seem to be stopping the wakelock!
Have you calibrated your battery? You should always calibrate after flashing a new rom. I'm not sure about the wake locks you speak of since I have never flashed a PA rom. Someone else may have some insight on that, in the meantime definitely calibrate your battery. I recommend this app https://play.google.com/store/apps/details?id=com.nema.batterycalibration. You must be rooted, I'm assuming you are...

Thanks, but since this is a wakelock issue with CPU processes running amok I'm afraid battery calibration won't help but to get a few more seconds out of it before it dies in an hour :/
I do think I have found the issue for now, but it's confusing that it's related, so if anyone could shed some light on it, that'd be great. If not, hopefully others who search for it will be able to look for similar issues on their phone.
In the past on other phones, I used the CPU Editor mod that you can find on XDA. I was partial to it because I got good results with the battery saver profile, and unlike other apps on the market that kept a running process, this one was all on the command line. For some reason when I set the profile through the command line and exit the app, as long as it's enabled, the ste-gps-interface wakelock flares up and drains the battery in a matter of hours since the device cannot idle. It was a tough connection to make because I had even disabled GPS entirely and was still getting the wakelock, so I'm still not sure what the connection could be. I did notice that putting CPU Editor into sticky mode caused the device to bootloop, so I wouldn't suggest this script for PA in my experience.
I have since switched back to just using Semaphore Manager to handle CPU and governor settings to keep stuff simple, which I probably should have done in the first place Sort of ironic that trying to squeeze some more battery out of that device caused the wakelock bug. I'd ask the author of the script about it, but it seems to be kind of dead - yet another reason to move on. Smartassv2 is good enough for my purposes!
I'm now having problems with this as well. Rebooting doesn't help and neither does a data wipe. I've been on CM 10.1 nightlies for the last couple weeks and this started on Saturday. Won't allow phone to go into deep sleep. I tried the Greenify method but it doesn't seem to be working from another post... Anyone have any more info?
Welp, I think its a hardware problem unfortunately... The phone went into Safe Mode last weekend when it got damp from rain. Probably due to that.
I've tried everything... I've reverted to stock and wiped everything via odin and it still wont sleep. Time for a new phone! Been a good (almost) 3 years.
Did you try to full formatting to FAT 32 (by USB connection with a PC) both the sdcard and emmc?

Possible Fix
Kind of digging up an old thread but since there was no solution posted, I thought I'd post this for anyone else having this issue and happen to stumble upon this thread.
I had the same issue with SlimBeans where ste-gps-interface was keeping my device awake. I just flashed the gps fix below and initial results show that my phone is going into deep sleep, hopefully this remains to be the case.

I noticed my NT with CM11 nightly installed(http://forum.xda-developers.com/showthread.php?t=2560827) becomes very unstable when battery drops below 50%. For example, menu pops up by itself, apps launch by themselves, screen changes by itself, and you name it. It is like it has its own mind! But once I plug in the charger, then everything goes back to normal. Anyone else has this issue or is it just me?

I have only seen it really bad if I had flashed the 10 touch LCD firmware, and on the units Ive seen it, reverting to stock LCD firmware corrected it.
50% seem unusually high for that, but even using stock B&N software there have been reports of whacky behaviour when the battery gets low.
I have had this problem with both stock ROM and CM10.x (2-touch) when my battery is in the 20-30% range. 50% is indeed a bit high for the NT to act up.
You might want to look into the battery calibration apps (I myself have not used them). Some of these apps suggest the optional step of letting the battery completely discharge after a calibration, but personally I would skip that optional step as there have been reports of difficulty in recharging NTs that are completely discharged.
My wife and I both have the Galaxy S4, verizon flavor.
My phone's battery usage is very nice. Most of the time I go to bed with 30-70% left on the battery. Hers does the same. The only difference is I use my phone a lot and she barely uses it during the day. A couple of texts, maybe a phone call and on occasion an internet search. Before this happened, and I don't know what was the tipping point, she use to charge her phone every third day, now she charges it every night.
Her phone is also 6 months newer than mine. Both are running stock, both are Android 4.3. I have both phones setup as close as possible so I can make comparisons between the two. Obviously she has different needs and will have different apps running/installed.
I have taken all of her apps off the phone and it hasn't changed the battery problem. I have reset the phone and still the battery drain persists.
I have put Battery Monitor Widget and GSam on her phone and I really haven't been able to locate the offending app/program/function. The only possibility is the 1013 system and "AudioOut_2". But that seems unlikely as this drain is about every 20 minutes and goes on all day.
Usually she runs with her phone in minimal activity. Data off, Sync off, GPS off, Power Saving on.
Here is a chart from a while back, everyday looks similar with the drains. My phone has long periods of straight white lines when inactive, hers just keep going down.
can't post the image of the battery chart. Gonna make it more difficult to solve.
Just wondering where to look and if this is something that can be solved or is possibly a phone problem/defect. As I mentioned, mine works nice and I have it setup as close to my phone as possible to get results that can be compared.
first of all im no expert, but i think it could go either way. before assuming its hardware it wouldnt hurt to back everything up, try a factory reset and a wipe mk2 odin flash. then seeing if the issue persists. just throwing my thoughts out there. hope it gets resolved regardless. :good:

Have you tried Better Battery Stats + a Wakelock Detector? Between those two it should be really easy to see if this is a software problem or perhaps a bad battery.
I'll link you to the wakelock detector I use. In my opinion it's the easiest to use.
Here

You can see wakelocks in BBS as well.... But I just like the options this one gives
Sent from my SCH-I545 using Tapatalk
I haven't tried BBS+, but Wakelock Detector has been running since the problem was detected. That is how I found the 1013 and Audio2_Out running. At the beginning it seemed to correlate with the problem but as time moved on it seemed less and less the culprit.
I haven't really found anything using wakelock detector. I could give you some stats off of it tonight when I have access to my wife's phone again.
Any stats that you'd like me to post I can do that. Eventually I'll be able to post that Battery Monitor Widget graph so you can see what is happening.
Pretty sure we can rule out a bad battery. About 99.9% sure.
First things first I would swap batteries between the two phones. Lets rule out a faulty battery first, because trying to figure out battery drain with a faulty battery can be maddening!
