Remember, I use Ultra Power Save Mode when not using Apps. I'm able to get by with only one charge per WEEK.
Using the Ultra saving mode really gets a huge amount of time before a new charge is required. My screen time shows only 3 hours and 10 minutes if I tap that area in the display. The rest of the time the screen was blank. The 21% for screen time means my unit was only active for about 15 hours out of the 4 days.
However, my unit shows it was idle 13% while the unit above shows it was only idle 4%. I don't use my unit as much as the other unit.
I believe the Samsung Galaxy S5 is the ONLY phone or tablet having this feature at the present time. Someone correct me if I'm wrong.
