Battery indicator Problem

[ZackSOC]

When I charge my S6 to 100% the battery discharge so weird, it discharges from 100% to 85% the 1% takes 8 min and when it reaches 85% to 75% the 1% takes only 2 min and w from 75% to 0% the 1% takes 3 min, so I think the battery indicator is the problem because the battery is good and still new I'm pretty sure about that, so can you help me with this problem and how to fix it.
Thanks.

More likely the calibration I expect. There are steps to take to calibrated the battery. Normally involves discharging completely then plugging in and charging up to 100% someone here should be able to confirm as this is my first week back on Android after a 3 year gap!
