I'm experiencing battery issues where a full charge only last 1-2 days, used to be 7-10 days, I'm using watch same way I have for last 2 years.
I'm assuming the firmware upgrade is the issue. Please could I roll forward or back from 1.7.62 to whichever version works properly from battery perspective?
