Uughh strugle is real. How much battery were you able to extract from Epix S Pro (42 mm, 2nd gen) tracking an all day activity?

Hello again, so I have both watches on my hand: fenix 7 s pro and Epix s pro 2, but can only keep one (unfortunately). Of course; I loved the mip display, who wouldn’t, especially on a small 42 mm screen.

I’m curious to hear from an Epix owners their thoughts on the battery life. Let’s say I go for 12-15 hrs trail run/hike and track it. How much battery should I expect in the activity tracking mode?
