I went and played a round of golf and body batter was at 60. Then after the round my body battery was at 45 which is okay. then about a minute after I finished the round Body battery shows un-measureable then just vertical drops 40 points to 5.
On version 13.37
I had to reboot it to get the touch screen to work before the golf round since garmin is very much pushing a touch only golf app now and because of the Sleep focus bug my touch screen trips out now.
But that was the only reboot I did.
