• KOReader version: 2021-05.90
• Device: Kindle PW3

Issue

In KOReader we can set AutoSuspend timeout. If it is larger than 10 minutes, Kindle goes to sleep at 10 minutes because this is its default.
Otherwise, it works fine (less than 10 minutes or Exit - Sleep).

Steps to reproduce

Set AutoSuspend to 15 minutes.
Wait.
Kindle goes to sleep in 10 minutes.

I suppose KOReader has no way to edit/override native sleep timer?
