Hi,
2yr old Fenix 5, been fine until recently, had a couple of occasion where battery is drain to 0% within an hour or two. First noticed a coulpe of weeks ago, did reset, also updated s/w to v25, seemed ok for a week or so, but then last night it went from 100% to dead overnight. No new settings/apps/widgets in recent months. Happens when not doing any particular activity.
Backlight at 10% already. Watch does track step count and movement through the day but always has and alst 1-2 weeks normally.
Any ideas appreciated!
