Display battery level in consistent terms

• The top of the page shows current battery level in miles.
• Charge data shows it in Start % and End % per charge.
• Drive data shows you kWh and % used per drive, but not start and end.

Why the inconsistency?  Pick one measurement and stick with it or let the user choose how to display battery usage.  It's frustrating to have to also do manual calculations just to make everything line up in my head when Im trying to compare my battery level at points in history.
