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.
Hi I'm having a really weird issues with my e970. It runs fines and I've checked the battery status with the *#*# code which says health is good. I've tried two different roms and I end up with the issue. My phone charges fine then will I'm using it it completely turns off. No warnings or anything. I plug it in and it says zero percent. I checked it a minute later and it goes up to 20 percent. Even on twrp or from the charging screen I get random percentages. Is it the battery or something else?
Thanks

Phone will loose some battery on every restart as every thing then needs to be initialised once gain
Not sure for others, but I just had MIUI rom installed and I found that the battery level reporting is flawed.
I fully charged my phone then leave it on the table (I am not using it at all) for 10 hours, and it is still showing 100%.
try battery calibration app by nema from store install it charge to 100, then drain it then charge.
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
Hello everyone, I'm new here on XDA, so i hope this is in the right place. I have a problem with an old i9100 that i recently got as a gift.
The phone was given to me without battery, so i bought one and immediatly installed Lineage 14.1 nightly (latest build, 13th dec). Then i started to notice that the phone would go off and the battery would drain to 0% unexpectedly. The phone works fine until the battery reaches a level of about 50%. Then the phone suddenly shuts down (sometimes i was able to see the screen flicker right before it happened). So i got the battery replaced, however the simptoms remain.
After regularly checking /sys/class/power_supply/battery/current_voltage i found out that the battery is mostly stable on 3.7-3.9v for an hour and a half until the 60%-50% threshold is passed in the battery indicator on the status bar. Then it rapidly drops the voltage down to 3.4/3.3v in a couple of minutes, where the phone shuts off. I have already tried to clear the cache and reset the battery stats through rootEssentials.
I was unable to find something meaningful in catlog's output. The moment of shutdown is around 22:13 and next boot is 14:19 (i left the phone with the battery off during the night). The log suddenly stops and starts again as if nothing had happened.
is it possible that i got two faulty batteries, is it a software problem or should i be taking it to a repair shop?
Thank you in advance for your help!
