My Mini Motion stopped logging after about the 15min point in my last session.
When I turned it on before I started, it displayed 2 red 1 green. Bugger - it didn't charge properly.
At the end of the session it turned OFF like usual with the red fade out, so it was ON for the entire session.
After downloading the file I found that it only recorded for about 15 - 20minutes of the 2h50min session.
