I'd like to use the apple watch but the garmin I have with a week-long battery (a bit less with longer tracking runs) remains the only viable option... Though given how Apple has paid little attention to battery across its whole range, I doubt future series will see a 7-day battery life.
I have a Garmin Edge for cycling and have had quite a few Forerunners for running.
Quite honestly..I have had many instances of Garmin devices running out of juice mid run or ride. Mainly since you always think I haven’t charged it in 4 or 5 days but it will be fine .. then it dies in the middle of a 50 mile ride.
Never had that happen with the AW because I know I have to charge it everyday.
Frankly .. dropping it on the charger for an hour a day isn’t that big a deal.
I am sure hardly no one wears their Garmin for 120 consecutive hours than takes it off and charges it.
For most who own an AW, the battery life isn’t a big deal. It mainly seems to bother journalists and those that don’t own an AW.
