"Completely" as in "down to 5%, then the internal battery takes over". I
don't do a deep-discharge, of course.

Mainly I want to avoid only ever charging from 80 to 95% and since I
have bought extra warranty for the internal battery, I want to make use
of that, too.

As I said, I am aware that this is not the best way to treat a battery.
But I am still surprised by it becoming almost useless in less than two
weeks.
