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
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
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!

OK, all day with swapped batteries. Same thing. My phone is fine, her's is still doing the same stair step battery drain.

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.
Sent from my GT-I9000 using xda premium
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.

Since you didn't seem to realize, I thought I'd tell you. This thread was 5 months old before you posted in it...
lol
I've read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?
sent on tapatalk on my htc rezound
if I helped please be sure to use the "thanks" option for me
First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:
Battery % left : 79% (mine) vs 88% (hers)
Data used overnight: 75kb (mine) vs 744kb (hers)
Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)
Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)
Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
so what did your betterybattery stats report?
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.
What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.
HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.
You have to have the widget on for the monitoring to be active unless you change the preferences.
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.
Battery % left : 84% (mine) vs 90% (hers)
Data used overnight: 279kb (mine) vs 498kb (hers)
Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)
Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
damnn thats just weird
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.
There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...
i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....
very bad....
very interested to see if its the phone or not - great work...
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.
HTGaming - I will check the PRI's tonight.
Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.
b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
I guess I was thrown by the screen shots. They both show some noticeable screen time.
the only other thing I could think to check is the email type, push versus pull, and the frequency.

The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.
I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
Hello all! I have been a silent user of these forums for a while now. I am finally turning to you all for some help because I am unable to determine if the issues with my phone should be treated as related or unrelated.
My phone: Image attached, no outside URLs. In short, Galaxy S2, ATT, 4.0.3, not rooted.
I have had this phone since about March. Ironically, I had a model of the captivate that was subject to the random shut offs. ATT worked with me and since my upgrade was so close, they moved it up a bit. Badaboom this phone. Enough with the stories.
Applications: Some utilities I have on this phone include juice defender, advanced task killer, onavo data manager, eco battery protector. I do admit to the use of applications like instagram, facebook and browsing through some websites, but the effect on my phone is not necessary what I am looking to fix. Also, I use ADW, but I have been a long term user of ADW and find it to be light on my battery usage. Never even shows up in my battery summary. I just feel you should know.
The issue: My phone is being a pain in the rear. I am trying to determine if my overheating and poor battery life are related. When in idle, my phone can drain within about 5 hours. When I first started noticing this, I would make sure wifi and sync were off 'cause I really didn't need it on at work. Still, maybe saved myself 45min of battery life in idle (some screen usage to check time and w/e). Then when I charge, the phone gets so hot I start to worry. I was used to my captivate getting kind of hot, mostly because of the cheat cover, so I've stopped using it and charging with it. Right now, I mostly use a dock to charge my phone overnight, but still, when I take it off its hot as Hades.
Usage: I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much : I have noticed a significant difference with juice defender on/off, maybe about a couple hours worth of usage. Usage for me is usually gmail, texting and sometimes yahoo instant messenger. (Yahoo has been pretty light on my battery, never really noticed too much and that kind of drainage is normal). Heavy usage might include me using my phone as my GPS when driving. I do this while plugged in otherwise it would be off before I exit my hometown. The overheating gets so so so hot that I might unplug it for a bit and turn the AC on. :crying: Also, I use things like instagram, facebook, gizmodo but I make sure to kill those tasks when I am finished using the various utilities I have. I make sure I'm on wifi when I use those and I have them set to only working over wifi with onavo.
Other Issues: Recently, there have been issues with charging. I have had random moments where my phone does not register it is being plugged in until I pull the battery. At first I thought it was my car charger and maybe the fuse on it was a dud but when I got home and tried my dock, it was still nothing. Then I tried USB to my computer and still nothing. After a battery pull, this was fixed. Happened about 2 times over the past 2 months.
.. I don't know what to do to get a balance back. This has been going on for about 2 months now and I can't keep looking for a power source a mere 4 hours into usage.
I am considering looking towards rooting and seeing what customization I can do to manage my phone better and achieve a balance right for me. I am familiar with the process and proficient enough to work through it. Due to my phone feeling too new, I have been avoiding it. I would hate to shell the money out for a new battery, given this phone is less than a year old.
Please please please gurus .... I need your help. I don't know what to do to get back to having my smartphone work for me efficiently.
Well first get rid of the battery savers. In my experience they crashed my brothers phone and don't save battery in the slightest. Just remember to turn WiFi and data off using a toggle. Also download betterbatterystats from the xda forums and cpuspy from play store and let the phone do its thing for a day

Task killers do nothing. Juice defender used to help back in GB days. No longer needed. Just use the phone normally. Also did u say yer on the stock ICS kernel? I was gonna suggest a factory reset to clear data and cache but if yer on stock ICS kernel don't do that.

The first thing I would suggest is to get rid of the stock ICS root then custom rom ICS after that get a little app called battery calibration, fully charge the phone and calibrate the battery i have used this app and swear by it as far as juice defender i have used it and never really cared for it it really never did what is said it would.
Hey guys.
It seems like almost everyone with battery drain issues has Android OS at the top of their battery stats.
I just want to share my experiences with this particular Bug.
Maybe it will help anyone. Please share if it also helped with your problem.
I had the Android OS bug since I dropped my phone a few months ago and had the screen replaced. The guy who replaced it (official Vodafone shop employee) said that they didn't just replace the screen and that something else was also damaged (they didn't say what) so they also replaced the rest. Well, that's when the Android OS problems started. I tried many ROMs and many Kernels. Sometimes the problem went away for an hour or so, but it always came back.
Then I finally decided to use BetterBatteryStats two days ago (I really should have done this earlier, I know...). I came to the conclusion that I had some sort of the well-known "fuel_alerted" bug, since fuel_alerted was the service that kept my phone from going into Deep Sleep.
This bug should have been fixed long ago but for me it somehow still persists, even on stock JB.
It didn't only drain a lot of battery (I had 8-10h maximum without doing much), it also used up a lot of CPU time, effectively slowing down the whole system to the point that I wasn't able to use Spotify on my phone without severe stuttering.
Well. I found a solution to the fuel_alerted bug.
The procedure is: turning airplane mode on, shutting phone off, taking out battery, putting it back in after a few minutes, turning phone back on.
This solved the problem. No more Android OS draining the power. Phone goes into Deep Sleep again. Only 2% drain after an hour. Spotify runs smoothly again. Yeah!
BUT well... It seems like the problem comes back randomly for me, today I had to replace the battery 5 times...
Now I am trying to strictly follow another "rule" to keep the problem from coming back: Always waking and unlocking the phone before plugging it in or out of power. I never did this before so it could have been the cause of the bug. Now let's see how long it stays bug-free.
If it still doesn't help, I guess I have to conclude it's some kind of hardware problem, which could only be solved by Samsung...
EDIT: Nope. Problem still there. So not really a fix, but maybe still helpful for somebody.
Okay, what ROM are you on?

It's the up-to-date stock Samsung ROM I guess. See attachment for infos.
Damn, it seems like the problem just came back without me doing much. I only checked BetterBatteryStats every 30 minutes or so and recieved 1 SMS just a minute ago. Seems like the bug started 20 minutes ago, when battery was around 78%. Now it's draining battery like hell again, Spotify stutters, Deep Sleep won't work...
Guess I'll have to pull the battery again.
Since I'm pretty new to all this: What kind of information would be useful to narrow down the source of the problem?
I can provide my BetterBatteryStats screenshots and logcat/dmesg files as well as my Android Battery Stats screenshots.
Is there anything else I could post?
Yeah, screen shots of partial and kernel wakelocks.

I just rebooted the phone, waited for a few minutes and took screenshots.
Here they are.
Okay, this is what you need to do now, drain it empty, charge it (while phone off) till 100 %. Remove the battery, wait for 90 sec or so, put it back and power on.
It's a placebo, but it might work.

Okay, I will try and do the charging overnight. Thanks!

I don't know much about kernel and ROM stuff, but I was just wondering...
As far as I understand, the fuel_alerted thing turns on if the battery charge goes below a certain threshold. The old bug with it was that, when recharging, the fuel_alerted thing would sometimes still stay on, even if battery charge is no longer critical.
Could it somehow be possible that this threshold is not set to 15% for me, but something around 80% due to some horrible bug?
This would explain why it suddenly turned on at around 80% when everything was fine before.
We're trying to adjust your fuel gauge and sort of calibrating your battery.
Sent from the little guy
Okay, I did exactly what you recommended.
Everything went well for about 2.5 hours.
Then the fuel_alerted process began again, but this time only for a short while apparently.
It took about 5 minutes kernel wakelock time in a 30 minutes measurement.
Way less than usual and when I check now, it's no longer active.
So. The problem might still be there, or it might not.
Do you recommend going through a few more recharge cycles to get the gauge set properly or do you think this won't make it better?
By the way, thanks for your quick responses!

Not really.
Now, when it gets to 15% or so plug it in (while phone ON), get battery calibration from play store.
Run the app, when it gets to 100 % hit calibrate. Plug off the device. Turn off.
Take out the battery for 90 sec again, reinsert it and power it on.
That calibration app is another placebo but as I said before, placebos sometimes work.
Sent from the little guy
Since the battery calibration app requires Root access, I flashed a Dorimanx kernel a few hours ago. Then I did a factory reset and the battery-removal thing. 5 hours have passed now without the bug, 3h of which were without wireless access (maybe it correlates with that).
I'll now let the battery (slowly) drain below 15% and then recharge it with phone on overnight. I will use the battery calibration tomorrow and will inform you about the results later.
Thanks man!
Good to know

I did the battery calibration. Bug is still there, no changes
Post you battery details and a couple of BBS screens.
Sent from the little guy
Okay, here are some screenshots.
From the graph you can clearly see when the bug started.
Is it normal to have >26 kworker processes running?
Something else that concerns me: >2h without or with unknown signal. The whole day I was in an inner city area where the signal should be good...
Can you conclude anything from the screenshots?
I will now try something which I also should have tried earlier
I have a spare battery (not original samsung, less capacity) which I just put into the phone.
I'll let it fully charge with phone off and then I will try if the problem persists even with the other battery.
If it doesn't, the problem might come from the battery itself...
Is this a good idea?
No it's not.
You gotta post detailed info there, we can only guess what's draining your battery.
Sent from the little guy
Okay... I posted the screenshots you asked for...
What more should I post?
