Why is the usage and standby time always the same on my iPhone? Why do the usage and standby times on my iPhone 7 Plus always show the same value?



I have tried restarting my phone and I have let it drain until it turns itself off to see if that would fix the problem (it has in previous versions of iOS) but does not seem to now. I assume this is due to some background process that refuses to quit. If so, how can I find out which one it is and how can I fix it? I would like to be able to track my battery usage properly if possible.
I have 2 possible solutions.


Downgrade your iOS version.
Use a separate battery tracking app. Just search "Battery tracker" on the app store. (As a plus, some come with widgets you can put on the Widget View)


If that doesn't work, then I suggest taking it to the Apple Store to get it checked out there.
