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.

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.
So I charge my Galaxy S2 to full (or at least, it says it's full), unplug it, and it says it's only charged to 60%, or 43%, or something random. I plug it back in, and off it goes, starts charging again, this time usually up to the "proper" 100%.
On top of this, the battery drain is very fast (10-15% overnight)
So, believing it's the battery, I get a replacement. Same thing.
I then learn that the reason might be because I flashed Lite'ning ROM while not on full battery, and that it just needs a battery calibration.
Ok, so I do a battery calibration - I charge it to full, drain it to 0%, then charge again. Take it off the charger, plug it back in to make sure it's full and...what do you know, the battery meter shows it at about 20% It continues to charge for about 4-6 hours after this.
Help? Is my phone faulty, or am I just not doing the calibration correct? I don't think it was like this before I installed Lite'ning ROM. So I'm praying it's not the phone itself?
The only other thing I can think that it might be, is the fact that it's a UK Galaxy S2, but I'm using it in Japan with a Japanese charger. Though I don't think that's an issue.
Any help would be very much appreciated.... not only does my battery not charge to full in one go, but it has **** life afterwards
did you try removig battery stats from recovery mode?

Yeah, that's what I meant by "tried the battery calibration".
Charged to full, wiped battery stats from recovery, then rebooted.
Try using app battery monitor widget, and check battery is actually charging it to around 4200mV, and discharges to around 3500mV at approx 1%.
100% is not full, it will continue charging for quite a bit after to around 4200.
At least you will know that the high and low scale is correct, and can monitor in between.

So I charged it overnight via AC adapter (with the phone turned on), woke up, and the phone was at 4%!
Seriously, what the hell?
Phone was indeed reading close to 3500mV via Battery Monitor when it was almost empty
Any help?
Try charging via usb, much slower than ac though, then check again.
Don't drain battery to 0%, certain reports indicate not good for the battery, others say no worries. Try 1% so the phone doesn't turn off.
Although the huge jumps in battery level indicate a battery issue; If still no good, try a different ROM, and recalibrate. Also try in flight mode overnight and check results.

Thanks for the suggestions man, I appreciate it. My main concern is whether or not it is a problem with the phone itself - the place I bought it from has a ****ty returns policy and won't exchange it or anything. So I'm hoping like hell it is something I can fix myself (new battery, new charger, different rom, etc etc etc).
As I mentioned, I'm currently on the latest Lite'ning ROM with Ninphetamine kernal I believe. Just did a factory reset/data wipe via recovery mode, thinking it would get rid of lite'ning rom and the ninphetamine kernal, but upon rebooting the Lite'ning rom theme (blue lightning on the icons, etc) is still there.
Anyway, I have it charging on USB now, and I have ANOTHER battery coming tomorrow, along with a stand-alone wall charging unit (that charges just a battery on it's own, not connected to the phone). Maybe I should charge the new battery via that for 16 hours, then stick it in the phone, wipe the battery stats via recovery, and flash a new ROM (say, the new villainrom)?
Yeah, forgot about that also, I have two SGS2 (one in for repair), and each time new have let is charge overnight without turning on before first boot. Then discharge to approx 1% (do not let it die), then charge fully to 100% and approx 4200mV. Quickly clear battery stats with Battery Monitor Widget (menu / stats / SU permission, no need for recovery as you'll waste battery rebooting and get inaccurate reading) and immediately disconnect charging. A new batt stats file will be generated.
At least with this method you'll know your at a "true" 100%.
Also, it may take a number of charge cycles for full battery potential, but don't let it die.
I use Cognition straight "out of the box" with no issues.

I have searched the forums but not found a thread which is similar to my problem.. I know there are battery drain issues with wifi etc but this is wierd and only started happening a few days back.
Basically i plug phone in to charge and it charges completely normally and quickly as it used to but only charges up to about 68/70% then it basically stops charging any higher, LED still red, charging display over battery still there. Turning phone off, rebooting, unplugging and plugging charger back in all makes no difference!
Any ideas what could be the cause of this? how to resolve?
I'm on stock JB, using the official wall charger and USB cable and i made sure the battery was full when i updated to JB as well.
Try a different battery, these are getting to the point where some will start to fail, six month warranties on batteries for a reason.
Well i have a £1.99 spare battery in atm as i run the original battery completely flat today. Seriously though be surprised if battery fail after 3/4 mths - never had battery dying issues on previous phones i've had until they were a good 2/3 years old.. Always a first though LOL
Its like the battery is saying its fully charged at 70%, now its completely flat i will charge it overnight with the phone off to full (if it gets there) and see if is resets the battery callibration or something.
Try to wipe battery stats via cwm recovery/advanced.

if you are rooted than download batterycalibration and untick 100% charge and click recalibrite and leave the phone on charge and it should charge up nto 100%

This app just wipes battery stays, so you can do same by going to cwm/advanced/wipe battery stats.

It has nothing to do with wiping battery stats. I think Kangburra is right...
UPDATE.
Shamed to say that i am not rooted yet... I have been there and done all that on my old phone ZTE Blade, but i really like the added functions that TW brings and don't suffer much in the way of anoying redraws or lag etc (although i do feel that TW could be optomised alot better along with better RAM Management)
I was going to at least root to sim unlock but got a sim free unlocked phone so had no need, then other stuff i wanted to do like freeze samsung apps etc is all possible without root and i've not come across that "I" need root at the moment.. was going to for APPS2ROM but i got no need to free up space yet.
Cheers for the suggustions though - I have that battery callibration app already (from old phone days) obviously don't work though.
Anyway - I am monitoring battery atm but it seems that running the battery completely flat until it turned itself off and charging overnight with battery off has resolved this issue - maybe this reset the battery stats and recalibrated it.
Its back to normal now, charges upto 100% as normal!! Fingers crossed this was just a blip
Although there are similar reports of battery issues, I haven't found anyone with the same issue. I have an SGS2 running 4.0.4 - all stock and although I'm on Orange, it's not an Orange handset. It's just over a year old.
Since being on 4.0.4, I've noticed the battery level drops when I switch it back on/reboot. It has been dropping by 20-30% but recently it's been dropping all the way to 1%. It has also taken to switching itself off with no warning (or shutdown) - I can only assume because it suddenly thinks the battery is at 0% despite what it was seconds beforehand.
As a typical example, it was charged to 100% (4200mV as shown via *#0228#). After a few hours standard use, it was around 60%. Then, seemingly when I'm doing something intensive like recording video or downloading something over a data connection, the screen goes off and I realise it's dead. I restart and the "battery critical" warning comes up - 1%. It dies again and I remove the battery for a minute, put it back, then power up. This time it says 9%. Then after a short while it dies again. So I connect the charger. After a couple of seconds, the battery charging indicator shows about a 1/3rd full. I switch on and the battery is now at 46%. Whatever the issue, reattaching the charger seems to rescue it - even if it's not back to the original level. The charge levels (in mV) seem to match the percentage.
This happened so much that a few weeks ago, it wouldn't even start and I had to wipe and reinstall everything. It does work now, but still crashes at least once a day. I'm not sure what else to do other than wait for Jelly Bean and hope that will miraculously fix the problem.
I have attempted "battery calibration" though it's a bit difficult - and I've read that it doesn't actually work anyway.
I am a noob - so please treat me like an idiot in case I've missed something obvious.
Thanks.
Dude, I believe it's time to buy a new battery.
1.Battery Calibration apps don't work(They don't do anythight good) Battery calibrates selfs...
2.I think that your battery is dead like my (Buy one it cheap)
3.And I think too that Insane gauge chip is very crazy...(You can reset it maybe helps... need flash Syiah and Get Stweaks)
I have the exact same problem, see this thread: http://forum.xda-developers.com/showthread.php?t=2062056
Tomorrow I will buy a new battery, I can tell you if this will help me out
Yup, battery calibration is a myth. Google already states that you do not need to reset your fuel gauge for ICS/JB devices. All battery parameters are automatically reset when it's 100% charge.

This is not happening for the first time...
Ever since I rooted my device and flashed Android Revolutionary Rom on it, I noticed some weird behavior with my device/battery.
Last night I drained my battery to 6% and I turned it off. This morning I charged my phone with the phone stayed off and when the battery indicator screen lighted up it was showing that 50% juice remains. Since this is not happening for the first time, this time I would like to test on it to see whether there's really this much juice remains. So I turned my phone on and as expected, the battery indicator shows 50++% left. So I play around with it and I noticed the screen flashing terribly after some time. Not long after that the phone hang there and I had to do a hard reset by pulling out the battery. Before that, I can see that the battery is drained to around 20%. I was unable to power it on after pulling out the battery and when I connected my device to the charger, nothing happens (no display, no LED). So I left it there charging and after some time, finally the LED is lighting up (So, I assume that I drained the battery COMPLETELY just now). I can switch on the device afterwards and it shows 6% battery remains. I wonder why is this happening as this only happens when I charge my device with it turning off. Something wrong with the battery? Device? Or I have to do battery calibration?

Let it charge to 100% first before using. Then check how is the battery usage.
There might be an issue with the battery also. If it is swollen then it's time to get a new one.
Try using another battery and see. If it works fine on other battery then your battery needs to change,
The problem could also be in the ROM. Something could have gone wrong during installation even though it may look fine. If this is the case then reflash the ROM with a full wipe. If the problem still remains, return to stock rom and see.
I had the exact same problems, the screen flashes and stutters, network signal is lost and the phone turns off, it is due to uncalibrated battery.
There's a simple fix, download battery calibration from play stor (green android icon with percentage), charge your phone to 100% without using it, then click battery calibr. inside that app, then doscharge it till 0% (do your normal usage as ussual) and then charge it back to 100%
For healthy battery life don't let it drain lower than 10% it's the li-ion physics and always charge it fully, don't charge from 0 to 30-50-60% because the ions in the battery will not have a good flow.
Everything has it's lifespan but if it's configured and used properly it can have a long lifespan
Also to mention, if my recommendation doesn't work, your battery could be swolen due to inproper charging / heavy oc-ing or your charger is messed up.
Also to say, that flickering occured to me when i flashed a new rom and when i do lot of reboots, then the batterystats freak out, the voltages also and also your phone.
Charhe and use it properly, try to stay with a rom at least a couple of days to see how it'll go.

The battery usage is normal, and its not swollen. I guess I will try to calibrate the battery or reflash the ROM again.
