Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

Its been on the charger since i posted. its only at 56%
3h 25m left
Screen 55%
Cell Standby 9%
SystemUI 7%
com.maxmpz.audioplayer 7%
Android System 7%
Its defiantly got something wrong as even though it says 56% if I unplug it, it will die in about 10 min. Even with a fully charged battery it does the same. Yes i also waited until 100% and wiped batt stats and at 3% left wiped stats. Screen is in standby

you can get better logs and information, plus if something is not easily visible to what is causing problems you can post up a log file for them to look at.

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

Hi guys just wanted to say my galaxy s2 is officially busted. Its still in working order do not get me wrong but something wrong with the hardware i think because i have flashed so many roms and stock roms to try and resolve the problem and i cant. My display is always sky high in battery usage and i cant get it down to save the life of it. Got everything on the lowest that is brightness settings and still nothing. Spoken to samsung and they say its not suppose to be like that and that display always high and as high as 60% is not right.
What can i do please cause i love the phone and it really pisses me off that it gets drained so bloody quickly? Shall i just sell it and get an HTC sensation instead or shall i send it to Samsung and be patient for ten days without my phone

Id say just wait for the new phone, the galaxy s II obliterates the Sensation. This coming from a person who's owned both devices.
About your display problem, sounds pretty weird never heard of an issue like that before.

What is your average display "Time on" on "Battery usage" when you're almost running out of battery?
How quickly does it drain? Don't you have warranty to get it replaced if it's actually faulty? I can't really decide if that's the case from your non-sense post.

My display is high as well with android Os in second most of the time and its normal, cause I use the phone a lot so obviously the screen will be high.
I get around 13-17 hours heavy usage so am happy I dont think its anything to do with rom flashing unless you get lower then 10 hours battery life
sorry i should of made it more clearer. Once i charge my handset as soon as i start using it you can see the percentage drop rapidily. i go into the battery usage and the display is at its highest and draining the battery. And that is with brightness to low settings. If i do not use the phone it can last me for a whole day and a half. But im to scared to use it for browsing and thats over wifi cause i know it will not last me to long...i know the handset is a battery drainer but come on the display should not be as high as it is..and with the warranty i have put the stock rom back so can they find out still that i had my handset rooted if i was to send it in

If you get two hours with screen on, than that's normal and not a hardware failure. Use white backgrounds as little as possible.
Apparently they could, I believe they some kind of count record of the amount of roms you have flashed and the only way to reset is by using a 'JIG' if you search the forums should be able to find more info on the 'JIG'
http://forum.xda-developers.com/showthread.php?t=1068522&highlight=jig+to+reset+counter
you might try some of the other forums about reseting it
Looks like SAMOLED+ consume most power on SGS2. I thought it's normal. Just know mine also having the same problem.
Sucks to be the guy who receives all these problems. I suggest, you just get a refund, as you should be ashamed of yourself if you sell a defective SGS2.
If you like the sensation, get it. It's also good, as I usually borrow it from my sister when we feel like exchanging phones for a few days. Sensation's default battery life is a little worse than the SGS2, as I only get 18hrs-1d 4hrs in the Sensation(still not rooted/default ROM) against the 1d - 1d 10hrs of the SGS2(Leomar ROM + Ninphe 2.2/undervolted).
My sister just got those chichitec 1900mAh batteries, and she said battery life on the Sensation improved(Only her word, as we have yet to exchange phones again this weekend). Now, all it needs is an undervolt + good ROM and the Sensation's battery should last a longer if not the same than the SGS2. Though you'll surely miss the SAmoled+ quality if you compare it with the SLCD of the Sensation, hope HTC improve on this department, they should have used IPS instead of SLCD.
A little tip if your getting the Sensation, is to thoroughly check its touchscreen sensitivity. My Sensation, is a little buggy sometimes, sense lagging/resetting + weird touch sensitivity. Though, I think it should be fix by flashing a good ROM + Kernel. Good Luck.

well im going to fully charge it again today and see how it goes. i have reverted back to stock rom and just rooted with chainfire kernel and installed titanium backup and unistalled all the samsung hubs and froze the wifi sharing bit. but my display is still high but i see how long i can get out of it i will post a screen after i let it drain down ..
and sorry to hear that you are having the same problem.

what is your display percentage and how can you manage to get so many hours out of it? any tips? i will be posting screen shots tomorrow for you guys to see what im talking about
If you have been using the phone the screen will always be #1 on the list, as its the part that needs the most power.
The phone will get about 6-8h of screen on time total before the battery is flat, but it will depends on mobile coverage (weak coverage will drain faster), if you are using heavy data, wifi usage (will be better than using mobile data on a weak signal or if you are pushing a lot of data round).
Generally radios will eat up the juice.
Also games will hurt.
You can use CPUspy to see what states the CPU is in, and if its going to deep sleep.
Also in settings > about phone > battery use, you want the awake and screen on lines to match up as much as you can.
(Music will keep the phone awake while the screen is off, and so will downloading stuff etc)

The truth is, that what you report as a problem, is not a problem, it is simply a fact. SAMOLED displays drain batteries like hell. Mine does exactly the same. Like you, I was starting to think that my unit was somewhat faulty, but soon fund out that it was not. In fact, the truth is that the galaxy s2, if left on with the acreen at normal brghtness, fully drains its battery in a matter of 5 hours or so. It is due mainly to the display draining something like 0.8 Watts, alone.
People saying they get almost 2 days use simply tell bullocks, because there's no way of actually using this phone and getting more than about 15 hours autonomy from its battery.

Moving to Q&A
Samsung support/RMA process has worked very well for me. Third phone already. Maybe ask them to replace yours?
I'm still confused over there. You're just talking without making any sense at all. The only thing I've got from all this is that you're complaining about display being the highest on the battery drain list. That means nothing. Or not much at least. Those values need to give a total of 100%, so if you're using your phone, and display is the highest, your phone is working really good, and you don't have the AOS bug. Which means your device is not faulty, you just don't understand the battery statistics screen. Pardon me if I understood your problem wrong, but if I didn't, just carry on with your life, your phone has no problems at all. I get around 1.5 days with medium usage, and I think that's normal for a phone like this.

You are not being rude at all. I have flashed yesterday batistas new rom and using jeffrey speedfrey kernel and i have fully charged the phone and calibrated it as well. I am going to let it die down and recharge it again to the max and see how it goes after that as well. My point of this though is as below on the screenshot. The display is always in that percentage and that is what has me worried. I have checked on other posts and the most that they get is 35 to 50%. I have the lowest brightness settings and it still that high..That is why i am asking if there is something wrong with my phone. I am getting good battery life so far just with medium usage and having wifi on since i have charged it but the display is what worries me. If someone could help me with these pointers as well i would appreciate it:
Does underclocking with Setcpu help battery life even more?
And what do you guys think of the screenshot?
i know this sounds silly but how does someone close a thread once they opened it i have a few i want to close..
Thanks again to everyone for you help..
It has dropped to 76% after 10 hours and a couple hours of screen usage. I don't think that there is a problem.

why is my display % so high though that is what im questioning. its not just for a few minutes its as soon as i get the phone out of sleep the display percentage sky rockets. and its that much cause the phone was asleep overnight
Hi all. I really don't know what causes my problem, so I'll just describe it:
Epilogue:
My Legend came with some Vodafone ROM so as soon as I got it I flashed 2-3 ROMs found on XDA (all in the same day, all were 2.2) before I settled for BlaY0's. Everything was working properly. After 3-4 months I decided to try a new ROM so I flashed a 2.3.3 with HTC Sense (http://forum.xda-developers.com/showthread.php?t=987251) - didn't like it much; then I tried a Cyanogen, also 2.3 - didn't like it either. So I flashed back the BlaY0 2.2. (also, in one day)
This is when my problem started.
Usually my battery would last for a day and a half. But every evening I connect it to the charger (at about 50%). In the morning the little light turned from orange to green and the battery indicator showed 100%. This was before! Now, I connect the charger in the evening but in the morning the light is still orange and the battery indicator shows something between 70% and 85% (I don't know if this is important, but most of the times is 85%). Usually it took 2-3 to fully charge the battery.
After a while, I noticed that if I reboot the phone in the morning, after the reboot the indicator shows 95-98%.
First thing I did was to wipe the battery stats (http://forum.xda-developers.com/showthread.php?t=765656) but either I did it wrong or that was not the problem because it did'n solve anything.
Then I noticed something else. When I go to SETTINGS>ABOUT PHONE>BATTERY I can see the UP TIME and the AWAKE TIME. I'm guessing that the up time is the total time since last reboot but the awake time I'm not sure; is it the time the display was on or it is more about CPU activity? Anyways, it seems that after I connect the charger, it thinks that it is awake because in the morning I can read about 8-9 h of awake time (during the day it reaches at about 1-2 h). So it appears that something consumes the power at a higher rate messing with the charging process. If so, why does the battery indicator heals after reboot?
Thinking that an app was causing the problem I eliminated some of them: Advanced Task Killer, Llama, Watchdog. The problem persisted...
Now I'm out of ideas...so if someone has some I'd be grateful. It's not that I need to reboot in the morning, it's the not knowing that's killing me!
Absolutly same issue here.
I remember seeing a solution somewhere in the forum. Try using search. I think there're many threads revolving around this issue.

There was a huge thread on this in General.
http://forum.xda-developers.com/showthread.php?t=1151450&highlight=charge
Unfortunate, until an alternate solution is found, it seems that replacing a piece of the hardware is the only way. Which sucks. I'm sorry.
When flashing a new ROM or switching between primary and secondary batteries in my wallet, I always make sure I calibrate it so the system doesn't misinterpret predefined untrue values regarding the highs and lows of the battery.
Actually, with my second battery, it takes an hour to charge from 2-60, then another one for 61-76, then the whole night til 100. It's quite horrible. The stock HTC battery excels at charging, but I digress.
It seems like a counter-solution to me, but maybe a temporary fix for you: Have you tried investing in a really cheap, secondary battery, perhaps on eBay? I bought two for around 2 dollars each, on separate occasions. My first I'm still using now, in my wallet, switches each month. My other one I bought recently, and the first time it dipped to 30%, it completely shut off. Needless to say, I threw it away, it was horrible.
@Asovse1
I read the thread...to be honest I never thought it would be a hardware issue. Anyways, replacing the motherboard isn't really a fix.
I guess your solution (having spare batteries) is the only one feasible. This kinda sucks!
Solution (see last sentence)
I have two HTC Legend phones here that both have this same problem.
I have read elsewhere that some people got the HTC Legend fully charged by charging it normally, like overnight, then powering it down and charging once more until the light turns green. Some repeated this procedure twice, i.e. pulled the charging cable, then plugged it in again.
I just tried charging with the phone powered down and got it to 100%.
But I'm still not sure whether this is just snake oil, because the indicated figure may not actually show the true charge.
Addendum: As I now know, it is snake oil. As far as I can tell, the phone charges normally. Only the indicator underreads. It does not reach 100%, it goes down rapidly, the phone keeps operating for hours with the indicator showing 3% or less.
And here is the solution.
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.

You can try JuiceDefender and see if it can help you extend a little your battery.

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.

try to reduce screen brightness it might help, and when on wifi turn off data plan might help too

Since you didn't seem to realize, I thought I'd tell you. This thread was 5 months old before you posted in it...

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.
Sent from the little guy
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
Sent from the little guy
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?
