How to reset or calibrate battery level on android?
Or delete battery stat.
Because my samsung tab a 2017 after pie last year,
Even after few software update,
When charging battery level most of time is show incorrectly
Yes maybe someone remember i ask before

Sometime will 86, 87, 88, 89, 90, 89, 88, 87, 88, 89, 90, ... 100%
Or 87, 88, 89, 90, 91, 92, 91, 90, 89, 90, 89, 88, 89, 90, ... 100%
Or will stuck on some %, like 95%, 97% even after half hour percentage no change

Already try
Clear cache partition
Charging with device off, even off battery level also show like that
Completely drain battery until device auto off, then charging until full without ON it
Use different charger, come with device, 15w fast charger and 25w super fast charger, all charger are come with samsung phone

I think battery stat on system corrupt.
If need factory reset then i will not going to fix
Device 2 years no more warranty

Still can last whole day
