Hi!
Battery life with new models:
Garmin has the 1-sec GPS battery life of the 5x+ listed as 32 hours - improvement over the current 5 and 5X watches.
New F5+ (not 5X+) it has a 1-sec GPS life of 18 hrs, reduced from the F5 of 24hrs.
The new F5S+ 1sec GPS time is now down to a paltry 11 hours.
I assume that’s because of the “maps” function.
Does the battery last longer if you don’t use the maps? The 5S+ is only 4.5hrs with music! OK for a marathon, but not for an ultra
