my goes to around 8 days, for example, 12% for the last 24h ( including 70min run with GPS and 30min strength workout ) Yes, exactly. I really don’t get the complaints about battery drain.

Always do that after an update as can stop little glitches. • 1 yr. ago. Thanks.. I attempted the connect to computer then disconnect the cable to restart. Doesn't work.. Might have to let the battery run out. Battery on my Fenix 6x Sapphire draining extremely fast. I charge it to 100%, it shows 21Days left. After 3-4hrs, it shows 14 Days left. Please look into the matter. EDIT 2: After 95% it returned into the quicker drain. I will give it one more charging cycle. if that doesn’t help I will return it. EDIT 3: After chatting with the Garmin support I uninstalled the Battery Widget (of course they want to rule that out) and did a hard reset. The first and second days seemed great (5.6% a day without GPS). A full charge was lasting around 1 week (depending on # of activities using GPS). Now that's down to about 1 day. I'm only getting some notifications and the the watch is restarting A LOT. pxLC.
