It happend when my phone frozen... I tried to unlock it but it was not response... So I did a soft reset and when my phone opened, battery saver was like that photo... I dont let it run in background.... Can u please tell me the differences from let it run in the background and not let it....
Thank u for the response
actually I don't know too
because Microsoft doesn't tell what this battery saver do in the background
but for sure battery sever will do its job even you disable it from the background
the "usage" graph still show which apps use the most battery even you disable it from the background
my setting is turn off battery saver and not let it run in the background and it seems fine for my phone, actually better battery life
