[Q] Annoying battery bug! - Galaxy S II Q&A, Help & Troubleshooting

I'm having very strange problem. I installed CheckROM v6 + speedmod k2-21 kernel on my phone and now my battery went crazy. Having some kind of drain when i restart the phone... Today I restarted my phone on 42% battery and when it booted up battery was on 21% and then started to rise to 22,23,24..
Anyone knows what may cause this problem? I also used BatteryCalibration app to calibrate the battery after rom flash.
Pls help!

Charge the phone 100% use the phone three days to give it time to recalibrate .
Flash a different kernel or rom .
That fails go to Better Battery Stats app and thread .

give your phone sometimes. anyway, having able to last for 20 hours is more than perfect. try ask iphone users.
i did ask few of my frens (iphone 4 users), he can't even last for half day, and need to have car charger, usb cable or pc just to prepare to charge the rubbish. lol
edit: forget to mention, they can't play game continuously on their rubbish. their battery will die in around 2 hours (i can have 5 hours continuous online game playing with s2)
btw, your so-called "bug" might be the system is trying to recalibrate itself to the nearest value with the battery level. should be a good news, better than the phone "lying" about your battery.

[Q] Instant Battery Drain

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.

[Q] Battery issues - Last hope

I hope hope you guys can help me with my battery life. And yes it's another battery life topic!
The thing is, I've got a lot of problems with my battery:
My battery only lasts 10-12 hours when I barely use it. This is a lot shorter when I actually want to use my phone
In the top left corner it always says my battery is full even though it's not
When charging battery, the percentage goes from 70-75% to 100% instantly
The battery stats are incomplete. Since unplugging this morning the stats say it's on battery for only 9 min.
When looking at the app betterbatterystats the data is incomplete aswell.
When unplugging the phone the battery percentage stays on 100% for 1,5-2 hours until it counts down, fast. In Battery Monitor I can see it goes from 4982 mV to 4181 instantly
The things I've tried to fix it.
Setting brightness to lowest level
Reset to factory settings
Hardreset
Disabling Sync
Clearing cache
Clearing Dalvik cache
Clearing battery stats
Calibrate battery
Stock kernel with Lite'ning ROM 6.1
Speedmod T41 Kernel with Lite'ning ROM 6.1
Disabling HSPA
The strange thing is, these problems started occuring around 4-5 weeks ago. I first thought I installed some app which was killing my battery but reseting to factory default and uninstalling all app's didn't help one bit. Are there any more solutions I can try solving it myself or is it time to send the phone to Samsung (and thus having to do without the SG for 2-3 weeks)? Hope someone can help me with this.
Current specs:
Android version 2.3.4
Baseband version I9100XXKH3
Kernel version 2.6.35.7 [email protected]
Build number Lite'ning Rom v6.1 XXKH3

Possible faulty battery .

Reset Battery Stats .
When charging battery, the percentage goes from 70-75% to 100% instantly
Faulty Battery/charger
The battery stats are incomplete. Since unplugging this morning the stats say it's on battery for only 9 min.
This is more like hardware/charger/battery problem .

Currently your warranty is void with rooted phone and or custom rom Samsung may not accept a warranty return or may charge .
Suggest flash stock rom or your original rom clear custom rom counter with USB jig .

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 .

[Q] Help with battery or voltage problem, I am concerned.

Good fellow, again around here bothering me. I tell the 19 May last buy a Galaxy S2, came factory sealed, in fact I remove the seal, the question is that since last Sunday something very strange happens to me: charge the battery at 100% and start using the phone normally when it reaches between 30% and 40%, begins to fade as the lighting of the tactile buttons and screen, that when I have activated mobile data and the need as more cel battery consumption between the headed or cel energy loss and lose the signal goes out, if I disable mobile data if it holds until the battery to discharge, but connect with the phone off and make me inmediantamente load of 30% when it is assumed that the cel was shut down because was downloaded.
To tell a friend tell me that you step on something like a SE x10 and it was the battery with a voltage problem. Then you believe it is, that the battery is damaged and not the power to mobile or mobile to be problem?
I wonder I did, I did the following:
Calibrate the battery with CWM (I deleted the batery Stats)
I did 3 complete cycles of battery
With a multimeter measures the voltage of the battery and gave me when it comes to 3.80% by giving the prooblema and 4.10 with the battery fully charged.
To rule out problems with the loader, load it with the PC, the battery lasted a little more me, but I spend as already mentioned.
I flashed 5 times and install the ROM Andyx
If I connect to the socket and use it although it is very hard not pass this probleme when I use it only with the battery, when it comes to the percentage of battery I have before mentioned active data and give it a very intensive use (internet, games, benchmarking, etc.).
Since I bought I notice that my view is loaded very fast and just as quick to download, but until Sunday presents ehstos symptoms.
They think it's worth it to buy another battery or mobile internal problem?
Probe version of ICS LPJ European modem with LPS, the LPW and now I have the ROM ROM Andyx Extremev0 Apollo kernel and all feel the same, with percentage and holds more than others, but all happens to me .
Please help and many thanks in advance.

S2 Battery Problem Please Help!!!!

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
