Issue about battery calibration

[umby75fg]

Hi, I have got SM-N910F with an IBestwin large battery (10000mhA) installed.
I flashed a Emotion kernel for Zerolemon (10000mhA) on my latest stock firmware (MM) and I made battery calibration many times but I notice a fast discharge from 100% to 82% and then the discharging turns to quite slow as should be I guess..
I used Battery Calibration app and Advanced Battery Calibration but I'm still noticing the same problem.
Do you know how can I fix it?

Did you wipe cache partition?

Wiping the cach partition would do the job, as cellphone batteries don't require calibration, nowadays.

Thanks both.
I'll try it and a new battery calibration included.
I know that for kernel replacing it's advisable to do a battery calibration..

Edit: I still have the same issue.
I did the wipe dalvik cache and system.
I hope that I wiped right because in twrp recovery I found many boxes and to avoid some problem I checked only Dalvik and System.
Did I wipe it right?
