My Clip charges itself, without being plugged in :)

I got home after using my clip most of the day and noticed the battery level had dropped down to 67%. I turned it off and about an hour later, turned it back on and happened to notice the battery level was only 70%. Not that I’m complaining - but how did it charge itself 3% in an hour while it was in my pocket :slight_smile:

Body heat.

Besides the fact the the battery level indicator is not totally linear and is at best an approximation. Once the load is removed (unit turned off), the millions of agitating electrons can settle down, giving a more accurate charge estimation.
