I'm looking for an app that shows/calculates:

  • time since last charging*
  • average time between charging
  • average charging time


  • graph history of battery level
  • charging current

Note: all above is a about stored electricity and not battery wear, capacity changes etc.

The app store is full of battery apps, but none I found had the above features (and they have a lot of what I don't need).

* The iOS Settings/Battery shows "Time since last full charge" in two parts: Usage and Standby. To get total time, do I add them? Or is the second the total time and the first a part of it?


About "Time since last full charge" : apparently (I observed the values for a few hours on an iPhone) the Standby value is "total time". At least in iOS 11.0.
