I bought an s10 some days ago and am currently analyzing, why the i have such a high battery drain (not lasting for a day, only 1-2 hours of screen time).
For this, I wanted to analyse all entries in the Battery Usage (screenshot 1). There I noticed that some entries are missing / not shown. E.g. the "Android System" is never showing up - although it has a huge portion of the battery drain (in my example 13%, out of the missing 34 % where the battery was used). See two attached screenshots, made directly after each other.
Currently I am extremly unhappy with the new phone, as I did not expect it to drain battery from the beginning and making it so difficult to analyse the problem
Overview of BatteryUsage
(Settings --> Device care --> Battery --> Battery Usage)
Selected App through Apps --> Show System Apps (the three dots to the right) --> Android System
Any help is much appreciated.
