Let your phone fully discharge once, then charge it while it's off for a few minutes and then start it. That's how I solved it when I had this problem ages ago.

[SOLVED] Battery Drops when Phone reboots

I've been facing this problem from the past week , i'm running the Sweet Rom on Galaxy Note n7000.
When ever i Reboot the phone , i get a huge battery drop , for example if the battery before rebooting is 47% , it goes to 15% when rebooted!
EDIT :
SOLVED !!!
SOLUTION :
Hey Guys ,
This issue has fixed , to fix this just charge phone to 100% then drain it to 0%
then charge the phone in one single charge and voila !
It will be FIXED!

The same here. I am on Ultimate XXLSA and i have the same problem, and is not only on reboot, just the battery run down very fast

Definitely the wrong forum. You may want to post this in the Q&A section

Moved To Q&A​
The dev section is no place for this.​

When does it happen?
Happen all the time u reboot?
Or only when ur phone freeze or get very hot?
If it happen when the phone freeze or when the phone get very hot, yes it happen like that since my galaxy s1 time. I normally change to other rom / kernel which won't make my device so hot.

[Q] Stock ROM battery drain after playing with Maclaw ROMS

After playing around with some Maclaw ROMS (cm10.2 and cm11) I went back to stock ROM. However I had big battery drains after that.
I did a complete wipe of user and cache and dalvik. I installed stock firmware with Odin. Did it over again with KIES. But still a big battery drain. Like 15% an hour. No apps installed other than the bloatware the in the firmware.
I've read somewhere about someone else who had the same issue, but I cannot find it anymore.
Anyone an idea?

Maybe you should try to format all partitions in recovery (except your internal and external SD card of course) and reflash the stock firmware.
By the way, 15% an hour is quite normaal for me.

Custom Roms battery drain, can be the 1ghz bug .
when you did alot off playing ( such as flashing from rom to rom an formatting again in a few hours. it cost you battery .
And now back on stock rom. Try to load your battery again to 100 % and see what will happen after it .
Stock rom = 100 % - 0% battery --> +- 20 hours
Custom roms= can do it longer.
but if you are a heavy caller, gamer. the battery will be down faster .

I've had the same problem. I updated the working 10.1 october version to the december version. After switching back to october version the failure was still there. Only way to solve it was a new battery - but it costs only about 10 € ...

i think that it is true that rom by itself is still buggy with cpu governer bug that causes to be stuck on 1ghz without dropping to 200mhz on the other side...when i try another version i shall make my jugdement more clearly

i got this problem on 02.13 release when i update to 02.16 problem was solved. didnt update 02.18 yet

Perhaps you should also consider the lifetime and usage of your battery. After months of charging and discharging once or twice a day, it´s not so unnormal that a battery goes weak...which has imho directly nothing to do with the used software...

Thanks for the reply.
I charged again to 100 % en let it go to 0%. It took about 9 hours, AIRPLANE MODE!!!
Checked CPU with CPU spy: it goes to deep sleep.
No apps installed except the bloatware the Samsung firmware comes with (and CPU spy).
Maybe it's just my battery gone bad/dead at the same time I tested the Maclaw roms. I already ordered a new one (2450 mAh!), but it takes about a month to get here (if it arrives all together; I live on a tiny little island).
However... I also noticed I do not have network coverage some times. Just no network. Could it be that if you flash it with Odin/Kies not everything is wiped and reinstalled? Like modem drivers (although it's strange the drain also occurs in airplane mode). To make it more complicated: I just moved to another place, so maybe the coverage is worse around here.
I just hate it if I can't pinpoint the problem

Hi,
I think you are on 1ghz bug if you have custom rom.
When you are on stock. This is not normale, your battery is going bad
Where did you bought a new one, im looking for a new one also.

Tried the 02.16 cm11 release => no change. Think my battery is just gone. I'll wait for the new one to arrive and will see then.

Hi!, I'm having the same issue here:
-Super-battery drain, specially when restarting the phone, huge 20% drops.
-Phone looses signal inexplicably,5 bars and suddenly dead, restarting solves the problem, but when signal drops, the battery starts getting HOT, even on IDLE.
-Im using Carbon 4.4.2 KitKat ROM on S3Mini I8190L.
Battery was working quite well with Cyano 11 about 3 months ago, switched to MIUI ROM because a friend recommended it, ROM started to be unstable, laggy and battery life wasn't great, had the same "signal lost" issues. Then downloaded the Carbon ROM and everything went worse.
-I always do full wipe, (davlik, data, interal storage, everything).
Any ideas?

[Q] Xperia TX Battery Problem

Dear all, I would like to ask, why my phone battery always drop to 0% suddenly when it was about 40% or 30% few seconds before?
I'm currently using CM11 ROM and I have tried to calibrate the battery but it is not working.
Is that possible that the problem is comes from my physical battery but not my ROM?
Please help!! Thanks!! :crying:

If it stays at 0% for a long time, then it could just be a calibration problem (although I haven't had any problems with any CM11 ROMs), but if not, it's most likely worn out; buy a new battery!

May I ask what do you mean "stays at 0% for a long time"?
By the way I guess a battery that used for 2 years should be quite old already right? Hmm have to consider letting it retired hahaha.

Some phones display the battery having "0%" left, but still have energy left and the phone stays on; that usually just shows a calibration error.

Nope. The sudden drop to 0%, means 0%, the phone cannot be turned on anymore. :crying:
So I think it is really my physical battery problem then.. Thanks a lot for your answer! :laugh:

I've encountered the same issue with my Xperia V. Phone always turned off at around 20%..
Replacing the two-years old battery with a new one fixed this issue and got me an additional hour of screen-on-time in addition.

pathetic battery

I am on Repulsa rom with mad max kernel. And the battery life is pathetic. From 100 to 20% there is no problem but as soon the battery goes below 20% it will literally go to zero in 10 sec and will shut down. It happens 9/10 times.. As soon as it goes below 20% it will shut down in few seconds.. This is not rom or kernel issue because this has happened with different rom and Kernel too.. If anyone can help it would be of great help..

I dont have that much knowledge but i am unrooted and happened to me serveral times as my battery shut downs in 13 percents. I looked for a solution and my issue resolved. Hope if it can help you
Maybe its calibration issue
Maybe your phone thinks 20% is 0
Try using fully discharge your battery until it shutsdown then go to recovery mode and waste the juice until it turn off and dont even boot into recovery. Then charge full with power off and again discharge to 0. Again to 100 and see if problem solves.
If not then maybe issue is with battery

I'm getting 5-7 hours here depending on the usage but to be sure go back to stock room for 5 days and check the SOT BY THE WAY I'm on Lightrom with the mad Max kernel

My phone used to be like this... so annoyed.
I tried everything but no result: using battery calibrate apps or methods, flashing stock rom, reinstalling TWRP,...
I am quite sure when your phone is at 20%-, you can't see battery % in TWRP mode :V.
I think the cause is TWRP ( data can't mount )
Here is what HAPPENED to my phone )
I flashed ECHO rom and my phone got bootloop..."Only official binaries ...."
Fine....too easy to fix... I flashed my stock rom and ta da... My phone's battery was Fixed :V
So ...you can consider bootloop your phone to fix the problem ))) Then wait 7 days without restarting your phone... reinstall TWRP ( "NOUGAT" or "OREO" ). And when you download dm-ver... zip to install TWRP, look carefully for LATEST version "LATEST". And dont update your TWRP or use themes for TWRP (Old is gold, simple is perfection :v , fuctional is too enough)
GOOD LUCK

Why wait 7 days with no reboot? Not needed if it's to make the OEM toggle visible...just wait 7 days or use the date-change workaround. Reboots affect the uptime timer but not the server-side OEM unlock timer.

Happened to me lately on stock, never rooted. Try turning off quick charge and use normal method instead for a few cycles. Maybe test on stock firmware just to be safe. If no improvement it might be a degrading battery.

I am thinking to factory reset the phone to see if the problem is solved.. N try the solutions offered ie calibration, quick charge off

Sounds good, just be careful with calibration...fully charging or discharging the battery reduces it's overall lifespan. Don't do it too often.

I did factory reset including internal storage wipe and calibration Bt still the problem exists.. Now the battery will go down to 15 then directly 14,12,10,5 in seconds even if I connect charger at 15 it will go down till 3%..

Yeah, it can be possible to degrade the battery that quickly.
It usually happens when you let your phone go under 20% frequently or let it die completely before charging it again.
I usually do the lowest 25-30% and the 80+% charge daily, then finally use it all the way to 20% before going to sleep, put it on a slow charger, and by next morning its at 100% without keeping it charged 100% all night (which can also degrade the battery, just a lot slower than discharging it completely.)

I have had my phone a week before it came out and my battery is awesome. It lasts me all day everyday. Best phone I have ever had.
