iPhone XS Max Inaccurate reporting on battery screen?..

[RWil85]

Battery life on my XS Max has seemed suspect for quite some time and I finally started to look into it..

Since my phone last came off of the charger - the phone is reporting “screen on” time of almost the entire 7+ hours. That is impossible as I know for a fact that my phone was sleeping in my pocket for the vast majority of that time. Leading me to my next point - the “screen off” time is wildly inaccurate as well.

What gives?

Pretty sure that there aren’t any apps I’ve added lately that are running wild, nothing with an extraordinary amount of background time, etc.


What could it be? Any ideas?


Thanks!

Apples screen reporting time is a bit confusing. Much prefer how Android does it, but once you get used to the Apple way it is fine.

Android resets the counter every time you charge to either full or more than 50% of what the life initially was. Pretty easy way to see how much exact time was used.

Apple looks at the last 12 hours, so if you charged in that time frame it’ll skew the results. The downside is that you have to guesstimate your screen on time based on the graphic. The upside to this is that the battery remaining time/% is more accurate.

If I had to guess, based on the activity graph, you’ve got about 3.5 hours of screen on time since your last full charge. That’s not bad.
