Is anyone else having issues with this phone loosing around 20% to 30 % after a restart. It doesn't happen everytime but sometimes when the phone is turned off and on the battery drops from, for example , 50% to 30%. I had this issue with official roms and unofficial roms.
Hi mali019, this happen to me as well, i'm not sure this is cause by the battery itself or the phone itself. My phone will auto restart when the battery usage is @ 4x percent. After itself restarting. The battery will drop to 33 percent every time. I'm swapping a battery with a fren of mine and started testing today. I'm using KG6 roms.
never had that problem...
Do you guys quit apps or just press the home button? Use the in-built task manager, it's good.
I don't use taskmanagers. Only use the one that comes with the phone. This problem happend on every rom i tried. From 2.3.3 to 2.3.4 . I'm gonna buy the new 2000mah and see if it happens again.
Just now i pulled out the battery without turning the phone off and battery percentage dropped from 41% to 22% . Currently I'm using KG6

Isn't that what I've said?
Anyway, you can try installing Watchdog from Market to see if you have apps misbehaving and what is using you cpu.

The problem is not an app using the battery. The problem is the phone loosing 20-30 % percent battery after a restart. The phone is not displaying the correct battery percentage.
I even had the battery percentage increasing after a restart without being pluged in to a power point. For example I'll restart the phone for any reason with a battery percentage off 50%. After the restart the battery percentage will show 23%. Sometimes the percentage will increase like its on charge. It will go up to 30%.
Never had this problem better get checked the battery in Samsung service center
Said that because it happened to me that if the phone gets hot, percentage drops. Later, it returns to a higher percentage.
I was experiencing the auto restart and instant battery drain issue while using ninphetamine 2.1.x
After changing to other kernel. No more auto restart nor instant battery drain issue.
You might need to a battery calibration.
I got a new battery ( Perks of working at a phone shop ) hopefully it will fix the issue
I also notice that it takes quit some% after each restart but not 20%. Actually the battery was good when I first got this phone. But after 175 apps installed, battery isn't good anymore.

Moving to Q&A
Today I left my phone in my room and after an hour I wanted to check my emails before going to bed the screen did not turn on so even after a long press on the power button, so I removed the battery (it was ice cold) after replugging it booted and voila there was a huge drop 50 percent perhaps? So I said to myself, I think I left a resource intensive app running and forgot about it and went to bed without plugging the charger, 3 hours later I wake up thinking it would give me a critical or charge your phone dialog, but instead I have a battery that charges itself ...
Now in reality that would be cool but i think there is a problem. Using the ninphetamine 2.0.4 kernel for a few days for bln but it was disabled, stock rom.
I have attached two screenshots one taken right after and the other one 3 hours or so after.
I don't think that I would need a recalibration after a few charges the phone is not a week old.
Hi, I have this exact problem with cognition+ Siyah kernel, how can I fix it??
So I changed the kernel and everything seems ok now, my problem was with Siyah Kernel.

I experienced same problem - I was browsing, then phone restarts itself and the battery is instantly on 18% (from 50%).
And then started to recharge itself.
Stock 2.3.4 ROM (version XWKH4), running the same configuration for nearly two months now, with only few restarts (once in 20 days), no new app installed recently.
Maybe some glitch in internal electronic?
Same problem, just a bit more drastic. My phone seems to freeze, in which I have to manually restart it. And then I see the battery falls sharply. This is on stock Firmware (unrooted) too.

Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
Hi All,
i am using a non rooted SGS2 in india. its running on the latest android firmware 2.3.6 (waiting for ICS.. )
the problem i am facing is that from past few days i see my battery drains very very quickly.. even if there is nothing running in background. i am using juice defender ultimate.. i guess its not helping either..
also it takes like forever to charge up.. i mean i plug my phone for charging at 17% after 2 hours it just reached to 21%..
at times while charging it through the USB.. it seems to be discharging.. it was at 37% after some time its reduced to 29%..
Also my phone heats up a lot for unnecessary reasons..
has any one faced this issue? please help...

first of all what programs run in background of your device?
second, what battery you use ? (1650 mAh 2000 mAh)
have you looked at your battery if the battery is working 100% or if the battery is damaged?
what rom is running on your device, which kernel do you use?
Could happen from rom. Here in germany the official 2.3.6 update was cancelled because of problems containing battery drain und reboots. Perhaps same stock rom problems in development.

i think your battery is gone. Maybe try charging it with the phone off or something. and if it it goes to 100% u can try download the battery calibration app on market to calibrate it properly. I would try everything i can before sending it back to samsung.
sounds like hardware problem mate, the phone should warm up when plugged but it shouldn't be above 35°C or so, and the slow charge problem could be related
if you can get another battery to test it out, or just buy a new one
good luck
You could try to reset your battery stats before going out buying a new battery.
thanks guys for your suggestions..
i uninstalled some of the crappy apps that i never used.. & voila my phone is back to normal .. less heat up.. battery lasts for 1 day.. hope it stays that way..
waiting for ICS..
@jeroensk - how can reset my battery stats..?
Clear battery stats boot to cwm recovery >> advanced wipe battery stats
But you will need a cwm and rooted phone ..
As battery stats do not need wiping dont worry about it battery automatically calibrates itself .
Some muppets think wiping battery stats actual does something . |It does not play any part in charging the battery or battery life on SGS2 .

I charged my phone during the night to 100% and used it for a bit this morning. I went to the beach for the day, and left my phone at home. Upon returning (roughly 5 hours later) my screen was stuck on the ATT splash.
I looked at my battery usage to see if anything strange had happened, and I was greeted with the attached image.
I am currently running stock ICS 4.0.3 from ATT. Rooted with Kernal version 3.0.35-Siyah-v3.4.2. I do have a lot of widgets on my home screen, but I have had this same setup for more than 2 weeks and nothing like this has ever happened before.
Pleas let me know if you need any more details. Any and all help is appreciated.

Download batery calibration app from market, charge until you get 4200mv, disconnect charge, calibrate then after succesful calibrate restart phone then dont shutdown until you get force shutdown.
If you cant get 4200mv, wait to the highest value then calibrate
Anyway your signals are very low, it will be drain battery rly fast, try make them highet and keep wifi shutdown

Why does low signal strength quickly discharge the battery? Also does this explain for the gaps in the battery info or is it something else?
Our phones do not require battery calibration. Have you installed betterbatterystats, and watchdog? If not, install them and see if it happens again. I can tell you that it's not the official update that's the problem, as I had it installed for a few days. Almost gotta be a rogue app. You could also try switching kernels just to see if it helps.

Thanks but again, whats going on? If I have been using the same setup for more than 2 weeks, shouldn't an occurrence like this have already happened?
I had a similar incident today running stock 4.0.3. no root. Phone went black. Once I noticed it, I restarted it which it didn't want to do at first. Went to the battery stats and it looks similar to yours. Battery level showed about a 50% drop. Never had that happen before.
Well I am going to try the first suggestion and see if that helps. I'll report back later.
It seemed that the first option worked pretty well. I let my phone sit for 8hrs today, and the battery only discharged to 87%.

Probably kuz it didn't reboot. It looks like your phone rebooted quite a few times for whatever reason, back to back, possibly got stuck in some boot loops too. Id call it a fluke unless it happens again.
And there is no "calibrating" our battery. If you reboot at lower capacities it'll come back substantially lower and then correct itself slowly over time. Its just how our meter works (voltage reading vs mah counter)
Okay, I have a weird battery problem and I don't know how to fix it. I'll give a description and then details of what I'm running.
So, last night I drained my phone and took out the battery to put things on the sd card and then I plugged it in and went to bed. I was late in waking up because, for some reason, my phone was dead. Very odd. I tried turning it on, and it turned on, showed that it was charging, and then proceeded to die. I tried again and again and I noticed weird things. I have the battery bar on top and the charging animation (shows bar sliding from right to left when charging) and the animation goes off about 5 times and then stops. The battery percentage is green, and setcpu changes to charging state, but the phone doesn't charge. I went into Settings > Battery and it said it wasn't charging. I don't understand what's going on and how to fix this. By some miracle, I factory reset and wiped and reinstalled the kernel and the rom and it charged as I left it at home for like 5 hours, but now i don't know how to fix it because while the charging state changes, the battery doesn't charge. Also, something else that is really weird is that with the stock battery, I installed battery calibration to see if I had just discharged the battery fully and it just needed more mAh to start charging, but my 2500 mAh stock batter is showing up as 3710 mAh (now. Was higher earlier).
P.S I restored the rom after it was charged and it doesn't charge anymore (still changes state, but no actual charging. I have two batteries, so I tried with the other and neither of them charge. I feel like it's a kernel issue and I could easily just flash another rom, but I would like to get to the bottom of this issue first)
ROM: King Kang July 16
Kernel: h0tkernel-r5
2500 mAh stock battery
Only using SetCPU to overclock and underclock
Flashed the rom a few days ago and it worked just fine.
The battery had been out of the phone for a good few hours in a cool room before I put it back on charging
(If you need more info, let me know)
Are you plugged into the wall or a computer USB port?
And just to clarify, you are using the stock battery, right? It's a little confusing because it sounds like maybe you weren't, but then in the list of items at the bottom you say you are using the stock battery.
I am plugged into the wall and using the stock battery. I just used the other battery to make sure it wasn't the battery's fault. Also, tell me if this screenshot makes any sense. This is from last night and I switched over to the jelly bean ROM too.

That looks like your screen is constantly on. That would drain the battery quickly. You may also have one or more rogue apps that are draining your battery.
You should definitely install Better Battery Stats to get a better picture of what's going on. The developer has a thread on xda where you can get help if you post the log from BBS.

It's just the clock app in night mode. I've done that with every other rom I've ever had and now I'm unable to for some reason. I've always had night mode clock on my dock every night. I don't understand why this issue started now. I'll download BBS and see what it reports in a day or two. For now, this problem is still here even though I switched to the Jelly Bean rom.
My sgs2 GT-I9100 got a new battery because the original one got swollowen , but now it also has problems occurred Recently,
Phone flickers and goes completely off at 40%-50% ,
Wont turn on again unless i plug it in but then it shows 0%,
Happens all the time,
So I restarted the phone at 50% to see SUPRISE then it shows less than 5% battery !
But after 50% its sure phone will go off any sec.
Is there a fix other than going to another new battery again? Tried the Battery Calibration app By a XDA member too...
UPDATE: Got anew battery ( 2nd battery purchase within a month) but it seems to be the problem continues..
Used the battery with the charge it came with... 60% browsed the web...... reached 35%...... Turned off again
Thinking that it happens because of a miscalibration so used the above mentioned app and calibrated at 100% drained till 40% ( light gaming) Went off again....:crying:
Please Help this is urgent!!!!!:fingers-crossed:
UPDATE 1
Did a Reset of the device and charged it fully with the brand new battery (left for couple of hrs after 100%) and I eventually drained it to 50% and did a restart I was left with 10% after.... didn't fixed
I'll try my best to help. Had this problem with an old laptop battery. I just looked a bit around and found that there are several apps that show you the real mAh. SInce I haven't tested of them I won't recommend any.
Are your contacs all clean? Can you measure the output of the battery with a voltage meter?
EDIT: Found this a few posts lower " just reset the fuel gauge chip (rooted) and you are good to go!"
Update flashed a stock jellybean rom lets see what happens
