Phone Shutdown when Battery is below 15%

Since yesterday, when the phone battery reaches 15%, the phone shutsdown. When I plug the phone in the charger, the "Battery Low" Message is displayed in Chinese but the phone does not start immediately. After remaining on charger for 5 mins or so, I can start the phone. When the phone is started, I see around 16-18% battery.
I have noticed today that its taking too long to charge and the battery dropped from 15% to 5% in 2-3 minutes.

Miscalibrated battery perhaps?

How to calibrate OPO battery to fix this issue ?

Root your phone and use the app BatteryCalibration.

Shuts down at ny percentage (( highest 51%))

As i said. It powers down nd shows 0% battery if i try to turn it on at that time.
and just when i plug in the charger it starts charging from where it turned off or below.
Been using 3rd party charger. Wasnt able to get yuphoria charger at the servic centres in my city.
if its a charger problem..
suggest a supportable charger ??
There i wrote it all.. Help me..

Try another charger of 1500mAmp or 1.5Amp
And next time when your phone shutdown randomly just unplug battery for 10 seconds and start then phone, you phone will start at where it turned off then again at shutdown do this process until you reach to 5% or below.
Now wait for automatic shutdown and this time don't turn on your phone until you charge it to 100% in power off mode.
Hope this help you.
And if your phone is rooted then plz tell me I have better methods

So your phone is rooted then download "Root essentials" app and calibrate your battery.
You can also try other battery calibrators

sorry for the late reply.. was a bit busy..
so i callibrated the battery and bought a new charger of op - 2.1 A. Charger tester app shows sufficient electric current for this charger so i think there is no problem with the charger. Now Before battery callibration. Shut down occured at 15% then it moved upto 40%. After Callibration and charging with new charger it shut down at 28% twice.. (( i hope its improving ))

[Q] Battery not charging

Hi guys
Since two days I'm having a weird battery issue.
My note is not charging beyond 60% although the battery is charging properly till that with a standard charger. But as soon as I switch to fast charging and restart my device, it shows 0% charging while switched off. Then when I restart my device it shows 0% but starts to charge really really quick till 50% in just 5 minutes or so. But still never charges beyond 60%.
Can anyone please tell me what could be the issue. I've tried wiping everything and switched rom but nothing's helping.
Is it battery problem or charging port problem?
Please help.

I'm having the same problem with my phone, just started the other day.

Can anybody help me with this?

Greetings and welcome to assist. I would try a battery calibration app and see if that helps, I have found a couple of threads on your device. You could see if the users there have experienced similar issues

Battery issue, software or hardware?

Hello,
I bought a second hand S6, and after some while I noticed a battery issue.
While discharging, everyting is normal until about 11-12%, when it drops to 5% and then continues like normal, 4-3-2-1-shutdown.
If I put the charger even for a second in any percentage below 5% it jumps to 8-9% , and then contunues the discharge from there without missing capacity.
If again I continue to charge without disconnecting, if goes lets say from 1% to 8% instantly and then continues charging like normal.
Is this normal for an old phone? Or can I fix it somehow?
I had never noticed anything like that in any of my android phones before, ever 3 years old.
I have already deleted battery stats, and performed 2-3 times full charge/discharge cycles, without results
The ROM is original 6.0.1 rooted.

Hello,
Tried at 100% and stayed at 100%
Should I try at 10% or 1% ?

It happens for me too. It's just Samsung's failure. Sometimes my battery jumps %1 to %17 when i plug the charger.
To be honest, you can't do anything about it.

I did the proceadure at 14% it dropped to 0% after some seconds and then shut down.
I charged it OFF but when it reached 95% went to 100% in seconds.
When I unplug at 100% and wait 5 minutes (always OFF) at next connection to charger showed 95%.
So it took me 1 hour of intermitted charges to reach 100% and stay there.
We'll see what happens next. I'll keep you updated.
