I understand that Apple Watch does many things in the background. But when you’re comparing something like an Apple Watch vs Garmin Epix.
If they’re both turned on for hiking they are in theory using the same processing power, measurements. Apple Watch isn’t doing anything different. So why is it so poor? What else is it doing…
It’s not about about the watch running weeks. It’s about being able to use it to workout without burning through loads of the battery in single day.
You have the Ultra where as many on this forum have the standard version. Apple Watch Ultra battery life is what the standard Apple Watch should be.
