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…
Wait, you’re comparing a 8 year old Apple Watch 0, released in 2015 , to a Garmin? Is the Garmin an 8 year old model as well? If not, it’s like asking why grandma is gasping for air after running a 10K from trying your keep up with a 30 year old experienced runner.
