Hello Guy,
I have been dealing with my battery issue on my Fenix 5 plus since a couple of weeks.
Indeed, my watch tune off after 6h of hiking with the GPS enabled . I did not change any setting since few montes, my watch is up to date.
I wanted to know if you have ever been this issue receltly with your watch?
Of course I called Garmin support just asking me to update the watch and reset the settings, It's what I did Disappointed
Thanks for your support and have a great day.
Gilles
