I use my inreach mini on bicycle rides. I have it start tracking and carry it in a back pocket of my jersey. When I check at the end of my ride I find that it has shut off. I turn it back on with the power button and it usually shows that it had tracked for about 30 minutes. My wife checking my progress on earth mate sees my track ending about about 30 minutes into the ride. Garmin support has no solution. I’m currently on the second replacement of my original mini. Problem still exists.
