Battery problem

Hi,
I have problem with in Jiayu S3 2GB. Under 50% battery drop to 0% in few minutes. Also battery doesnt last long , max 3 hours screen time and it is problem to use it whole day withnout charging, but normally screentime should be around 6 hours what i read.
I recived phone with Android 5.1 2015-06-23 tryed flashing newer version 2015-07-14, also tryed battery calibration, fully charging, discharging few times and still same.
When is fully charged voltage is 4,2V (measuded with app battery calibration) at 50% is only around 3,6V (this is almost 0 capacity for lion battery) and is turning off at 3,4V.
Have anybody simmilar problem? It looks battery is bad not just software problem, but dont understand that it is showing 50% for that low voltage.
Thank you

IF you are on lollipop then its software problem as 5.1 seem to have the battery bug, and never calibrate battery on MTK devices, Calibration apps mess up MTK phone,they are not made for mtk devices.

I recieved phone with defective battery, after changing it dont have any battery problem even with Lollipop.

I noticed that battery discharging very fast below 8% (Stock 4.4.4 13.08 and other KK versions)

Well, i had different problem
My phone didnt charge, no matter how much i change cables or chargers.
But when the device was shut down, charged well.
I bought mine from pandawill, so i sent them a mail,and they sent me another battery...
In the meantime, the problem had solved, maybe the battery calibration i did helped.
Anyway,i got now 2 batterys...

I also have the problem and have the following conclusions:
1. Battery level will be displayed correctly after a reboot. Otherwise, the battery level indicator doesn't change as quickly as it should: it doesn't go up as fast while charging and doesn't go down enough when in use.
2. The point where the battery indicator starts going down by about 5%/minute varies and is in connection with the time it has been used. After two days without charging and without using the phone for more than one or two phone calls, it happened at around 5%, while lots of screentime made it happen when the indicator was above 50%. Some experimenting made it clear that it's not the battery's fault (in my case, at least) but rather a software problem.
Using stock KK 4.4.4.

Try to go battery settings and find out what application is eating your power.

Hi! I have this phone and few weeks ago I had a similar problem, when my phone had about 20%, it spend a lot of battery and in some minutes, it was without battery. I installed the Xtreme Rom and this was fixed. I hope you can fix your problem too with this.
Sorry for my bad english

Battery not charging when on - Solutions ?
Hi all,
My Jiayu will not charge when the fone is on, will only charge when switched off.
Any suggestions ?
Thanx Geoff

Known problem.
Saw it at my phone and in another phone.
How to solve: charge with original charger and cable and then switch to the other charger.
It worked for me twice.
Play it a little if its not working, switch cables,chargers, turn on and off...
Good luck.

Note 4 battery problem after flashing some custom roms

Hi everyone, i have problem with my note 4, battery drops from 11 % to 3% very fast and charges after 85% very slow.. this problems started 2 days ago when i flashed dn5 custom rom i thought it was rom problem and flashed sixperience rom but still i have same issue also i tried battery calibration but again.... what can i do???? and my screen on time is only 3 hour. please help me, thanks.

Have you checked what's eating away at your battery? Settings => Battery (Here you should be able to see if anything is causing a drain).
If the settings screen doesn't seem to show anything, you could try BetterBatteryStats (This app will be able to tell you everything that's going on regarding running processes, wakelocks,... You should give it a day or so from a fully charged battery.)
And if even BBS doesn't show anything, I'd flash the stock firmware again (And check if it isn't the battery).

Well, in all fairness, mine is running CM 12.1, and SOT is a bit under 4hrs. Which isn't fantastic either. Quickcharge does slow down a bit after a certain percentage. You could try a new battery, but might be a waste of money.
I'm afraid I can't help you any further, maybe someone else can.

did u change ur battey? im going to buy anker battery as i know they have good ones

I am facing exactly the same problem .. I don't think buying a new battery will solve this problem.
My mobile is charging by AC very very slow and sometimes it stuck at certain percentage for hours and I tried many things but I am still facing this problem... While recharging if I removed the battery and put it again, the phone shows me that it is 100% while it was not 100% at all.
I wish someone can help us about this problem or if any of u guys tried a new battery and the problem has been solved, so please feed us back in here

Any updates!?

well after 3 4 days (i mean after flashing sixperience rom) everything is ok. discharge to 0% then wait and full charge + calibrate battery may fix issue. but still dont like screen on time. only up to 3.5 4 hours

That sounds weard...
I mean the good thing is we could change the battery.

I have a feeling this is not battery issue. it's exynos + apps running on the background. Try to root + disable unnecessary apps (maybe Android 4.4 Would give you higher SOT). I had Note 3 previously and SOT was at the level of around 6 hrs (snap processor) - now on exynos it's around 4 hrs on stock firmware (5.1.1).

mobile not charging over some %tage

hello guys, i m using latest rom of lollipop and before it i was using RR , in both ROM donno y after some days battery not fully charge some times goes to 70 sometimes 77 , plz help i don't want to go back to stock rom
thnxxx

I've had the same problem. It first started with CM12.1. Reverted back to stock and it was working fine. After a while I noticed that my battery was bulged, so knowing how dangerous Li-ion batteries are, I bought a new battery. But after I got the battery I noticed that the problem still persists. After a while, the battery charges slower and slower, and I went back to a CM12 version, And even stock... same behavior on both. I do not know what the problem is, so I downloaded an app that tracks battery usage, battery charging Amps and a bunch of other things. What I found is that when my battery is empty, and I plug in my charger, the mA flow coming from charging and into the battery is over 800mA... but as the battery charges this value drops. Today, it reached 90% and wouldn't go higher. The Amp flow was somewhere around 70mA to 12mA.
I removed the battery for a few minutes and then put it back in. After putting it back in, the battery status indicated that it was fully charged 100%. I don't know what it's going on. Please help.

That happened to me
And my battery got fatter
I had to replace it
So i really recommend you to stick with Stock
Ot if you really want cm12.1
Charge your phone to 100%
Keep it plugged while installing cm12.1

Don't know about that. But you keep running your batteries flat and you'll see lol. These devices are plagued with a bug known as deep discharge. Sometimes they won't turn back on. For minutes hours or days. Do to low battery. Sometimes only way is USB and wireless charger. Others never. I'd watch out draining it below 15%

Anybody know why bank apps detect root after phone is turned off or battery goes flat?? Does not happen on my s10

Xiaomi A1 Charging and battery drain on AEX v7.3

After rooting and flashing AEX v7.3(android10) on MiA1, the battery got drained too fast even though i restrict battery usage and data on every apps and system apps. I use fast charger yet its showing "Charge Slowly" and will takes 2days to completely fully charge the battery. Is it the rom? I charged it the whole day yesterday and still its only 37%. Can anyone guide me or help on how to fix this issue?
And what is the best rom to install for miA1 that can resolve this battery charging and drain issue? Thanks in advance if anyone can give me some guide
