I've been using my Note 4 for more than 2 years now and I'm absolutely happy with it, except for that one issue: the battery indicator on top does not match the real remaining capacity of the battery. The battery is still ok in terms of its "fitness", it usually allows for a whole day of (power) use. But it is annoying to see that the phone turns off at a shown power level of 13%, sometimes 16%. When I then plug in the charging cable, the charging screen shows the last level like 13%, but I think it really is 0%, because if I turn on the phone shortly after plugging the charger in, it turns off again before it completely boots up.
Is there a way to calibrate the battery level in such a way that the indicator gives correct resp. useful values again?
