Just looking at the specs: Fenix 7 Pro has 18 day battery in smartphone mode. Epix has 14 days only (and down to 6 days with Always-On-Display). Obviously, if you turn up brightness, use exercise, and GPS, the actual battery life will be shorter. 15 days for Fenix 7 Pro seems very reasonable. Get Epix Pro if you want AMOLED.

Has anyone else noticed extremely poor battery life after the most recent software update? I have been able to get a solid week out of my Fenix 3 HR since purchase but after the most recent software update, I can barely get 3 days. And I'm actually using it much less - moreso as a normal watch and for phone notifications due to an injured ankle.

Took it straight from the charger to a quick 20 minutes run and the battery was about 89%. If my math is correct that's a 30% drop in 1 Hour of use. (with advertised features). 3.33 Hours with GPS / Music. Here are my issues. It's definitely below the official battery specs. It's a new watch with a new battery.
