Hi all
since a week or so i have a strange problem with my sgs and i hope you can help me to fix it
Everything works just fine (battery is accurate) until i switch off / reboot the phone
but at next boot the battery reports a very low value
(e.g. the phone has 55% battery left and after the reboot it reports only 8%)
with Froyo 2.2.1 (Speedmod Kernel) it would stay at that level until the battery has really drained to that point
With GB (JVQ - Galaxian Kernel) the battery percentage increases slowly
What i tried so far:
first of all, i deleted the battery stats for a few times and because that didn't work i upgraded to JVQ (with repartitioning and all), but that didn't solve the problem either
i don't really know what to do anymore and i hope someone can help me
thanks
Just do a few drain/ charge cycles and that should sort it

First off, wiping batterystats.bin alone won't help.
Try this:
1. Charge to 100% until it says unplug charger.
2. Wipe batterystats.bin from recovery, unplug and then reboot
3. Drain your phone's battery until it shuts itself down
4. Charge to 100% without interrupting the charge
5. Enjoy :3
thanks for the quick replay!
unfortunately thats basically what i have already done
since the problem happened the first time, i have charged the phone at least 5 times and wiped the battery stats for 2 or 3 times right after charging the phone to 100%
its true that normally i don't drain the battery completely, but yesterday i have done just that and than let the phone charge overnight - but that didn't solve the problem
i will try to fully discharge the phone a few more times and load the battery while the phone is switched off
still i hope someone has an other suggestion how to solve this annoying problem
thanks
lol - stop deleting the batterystats.bin for starters.
The batterystats needs to indentify the top and bottom markers such as 0% - 100%, delete it ONCE.
Firstly, turn the phone off, charge the phone to 100%, bump charge it, till 100% truely.
This means, unplug...then plug it in again until you keep getting 100% show up.
Boot up into recovery then delete the batterystats.bin.
Use it heavy, activate everything and drain it. Make sure it is compeltely drained, try turning the phone back on, take the battery out for about 2 mins, try turning it on again, if it doesnt turn on, you've drained it.
Plug your charger in, do not turn the phone on, let it charge to 100%, again, bump charge it until 100% truely full, turn the phone on and let it run its natural course this time.
Do not delete the batterystats.bin again, you will have to repeat the process, it will take a good 2/3 times of charge/discharge for the stats to settle.
Hopefully helps dude! Good luck
thanks pidz!
just to clarify: i have had my sgs for a half year now and i never wiped the battery stats until last week
But i haven't tried bump charging jet - i really don't like that process as it is bad for the battery but might be worth a try, thanks
it usually happens with non original batteries. did you changed a battery? or maybe you got a fake one with you phone?
I have Aurora ICS in my U8800. Yesterday I removed SIM to another phone and turned U8800 back on. Battery level was 80%. Listened music, used wifi a little bit... and today, 12 hours later battery level was still 80%. Reboot, and now the battery level is 40%. Plugged in charger and two hours later level was still 40%. Reboot, and now the level is 100%.
What part in Android system handles battery level changes (and updates changes battery indicator). And why does SIM play any role in this situation? And most important question now is how can I refresh charge level without rebooting (and without SIM of course)? Tried some battery widgets from play store but without luck...
try this

just charge your phone for 3 hours, i think that should be enough for full charge.Do not unplug it, Go to recovery wipe battery stats, and leave it plugged in for another half an hour. that should solve it.

not everyone have clockwork recovery my friend
anotherway to resert battery stats its free apk calld battery calibration
here is link
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
it needs root.
best way to calibrate battery is fully charge then unplug restart device plug in charge till 100% and do it again over and over for 3 times then... calibrate battery
fully discharge and charge again till 100 w/o breaks
Ok, tried that what rjspark89 suggested. No help.
But when I inserted an old, deactivated SIM-card into phone, everything worked fine.
So, something is not working the way I think... Now using U8800 as PDA for a while. No phone but BT and WIFI are working, and battery charge level changes as expected. Case closed
(and yes, I have Clockwork Recovery in my phone, and battery calibration app(s) are familiar too)
Does anyone else have a massive battery drain in Kit Kat? I can charge my Nexus to 100% and in an hour or two it's completely dead with blinking red light. I tried restarting to bootloader when it was at 5% but it was still on for like a half hour. Once I restarted my phone, my battery read 0%. I'm thinking it may be time to change the battery if no one else is having this problem.
I suggest you to reset the battery stat from the recovery. The probability that this works are low but is better then nothing.
How do I do that from recovery?
Edit: phone was charged to 98%, rebooted into recovery to see if I could wipe stats in TWRP, rebooted again, phone reads 28%, 3 minutes later it read 66%.

To wipe battery stats in TWRP:
boot into TWRP recovery
/advanced/File Manager/
folder /data/system/
click batterystats.bin
click Delete
reboot system
If you can't see the folder, you need to mount the data folder.
Well I switched to Philz Touch, do I have to do the same thing then?

You should have the wipe battery stat under advanced in your recovery.
The right step to follow are:
1. charging the battery FULLY
2. wipe Battery Stats
3. don't charge the device until the battery still turns off your device because it empty
4. now again FULLY charge without interruption
Wiping battery stats does nothing, see here: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ . Sounds like your battery is borked. May need to send away for repair. Are you still under warranty?

Yeah I figured. Thought it was a KitKat bug at first but then it started getting ridiculous. Phone was at 70%, started taking a photosphere, phone shut off, and when I turned it back on it was at 3%.
No its not. Bought it off Craigslist. Just gonna order a battery off eBay for $18 and replace it myself, see if that fixes anything.
I just got out of a similar problem.
My battery percentage was jumping all over the place.
It would charge fully in about 5 mins, and die in about 20.
Everytime I restarted the phone, it would read a different percent.
I ended up running the phone on full brightness, with like everything turned on to drain the battery all the way down.
& Everytime it would shut off cause it had no battery left, just restart it and keep draining it until when you reboot the phone it no longer turns on(because the battery if fully drained of course).
That's when it is really dead.
Then just charge it to 100%, and keep it charging for about 20 extra minutes once it hits 100%, and now it's back to normal!

That really worked? Any problems with it since and is this a common issue with the N4? For some reason it won't die when it's in the bootloader even though the percentage read 5.
So yesterday it was so dead that it gave me the red blinking light, should I charge it when that happens again and should I leave it off while charging it or turn it on and not touch it?
How many times did you have to do this until it straightened itself out?

I am currently having WakeLock problems, but I do not beleive this was the cause.
I was able to restart it after it died about 4-6 times, till it was fully dead.
Then I charged the phone, and kept it off the whole time.
I installed wakelock detector to make sure that wasn't the problem. I had this problem on the stock rom even before I rooted. So the problem hasn't persisted since?
Hey everyone. So I bought a second hand note 4 recently and have been having battery problems.
I did a full wipe install of CM13 and the battery dropped to 0% at random times and I had to plug it in the charger for the phone to even boot as it would just restart as soon as it turned on. Anyway, i thought this is probably due to faulty battery. I purchased another one and now this one doesn't reboot at random times but seems like the phone keeps reading the battery percentage wrong, sometimes it doesn't charge over certain percent, just gets stuck at 77% or 63% or any percentage really. If I remove the battery and plug it back in, it shows a completely different percentage everytime. I have tried wiping battery stats, do a full discharge/charge, nothing seems to help. Battery drains fairly fast too, once I manage to get it to 100% it shows that expected time is like 2-3hrs if screen on. Thanks!

battery displaying different percentage after u remove it and put it back in is normal i have 3 note4s all do the same (up to 10 percentage change, it either increases or decreases) but the other issues like getting stuck on a certain percentage are not normal make sure u have the genuine battery and try stock rom.
yeah, i tried stock and the same thing really. such a random issue. I just noticed that battery charges once I turn the screen on and use it , so it only gets stuck on random percent only with screen off.

yeah, i said I wiped battery stats, which is basically recalibration
once the battery is charged to 100% it also drops first 10-20% really fast and then it gets better but still I only get around 2hrs screen time

Oops my bad..Didn't read your whole post...
the only way to fix this replace your battery by new one
i tried all options (Format ROM - Wipe battery status - Getting back to stock ROM - Unroot - re Celebrate apps - Changing recovery-Removing battery from device for while sleeping - charge without fast charge - charge via USB)
i asked myself after that all of this headache doesn't worth 20$, i replaced the battery with new one and its working fine now

yeah, i replaced battery as well but it's still the same issue. old one at least charged fully but would randomly reboot on me, the new one doesn't reboot but drains extra fast and doesn't always charge fully. can't believe both batteries are faulty
I am sorry for summoning this old post but did you find any solution to your problem? I have exactly the same experience with my note 4.
Thanks!
Is there a solution for this problem?
Power down and then out-and-in same battery and my stuck-at78%... was 100% when started.
if you having problems with auto restarting.... download the app " WAKE LOCK" and put it on Partial Wake Lock setting... your restarts will be a thing of the past.
So for the past few weeks my battery has been draining faster than the speed of light. It will get to anywhere between 30 - 70% (usually about 56%) and it will just turn off. Like straight to dead, no powering down.
When I try to turn it on again I get a white screen with a picture of an empty battery.
If I plug it is, I get the charging screen showing a battery percentage the same as it was when it crashed.
I've done a factory reset, wiped the cache, tried it with no third-party apps, all sorts. But it's still the same. I'm having to charge it 4 or 5 times a day and it's only getting about 30 mins of usage before it dies.
It tends to happen the most with the camera or Snapchat but I don't think it's related to those as it will also do it in other apps and even the lockscreen.
Is it time to call it quits and send it to the phone shop in the sky?!
I had this weird problem with my battery too! MXPE on stock nougat , as soon as I charged my phone to 100% and plug out it used to drop below 80 in 2 minutes ! and then when the percentage hit ~20% It used to turn off showing that white screen you mentioned, however when I plugged the phone in it would start charging at ~15% ! so I tried recalibrating my battery and it is surprisingly effective !
here is the method:
1) drain your phone battery until it shuts down.
2)power it on again and you will see that white battery low picture. plug the charger for 3 or more seconds and out, it will boot up again but as soon as the Rom boots up the phone will die again . do it multiple times.
3)charge the phone while it is off until 100%. turn it on and drain the battery as fast as possible (max brightness, volume, streaming videos on cellular data and running benchmarks will do ) till the phone dies again.
4) repeat (2)
5) charge the phone up to 100% while it is off ! and there you go your battery is recalibrated and good to go!
Obviously, this will shorten the batteries lifespan but since I believe you have it for a long time It won't be an important matter!
Thank you. I think I'm going to bite the bullet and treat myself to the new OnePlus 5T when it goes on sale tomorrow but I will try your advice as this will be a good backup phone to keep for emergencies as it's not worth much to sell on or trade in.
Try removing the back with a heatgun and unplugg and plug de battery.
I'm having the exact same issue and tried the same solutions, no help. It's dying now after a couple minutes. I'm carrying around a battery pack.
Seems to me my troubles started after updating to Nougat. You?
