My Epix Pro 51mm battery life is better than Fénix 7X Pro battery life. This is with AOD on and using it at the exact same time on left and right hand with same number of workouts/GPS, etc. What is going on here? I get around 11-12 days on Epix and around 10 days on 7X Pro.
Despite the fact that AOD on AMOLED display is not comparable with MIP one (1Hz update), it is remarkable how long it can run on a recharge. Anyway, your Fenix 7X Pro must have some issues (let's hope it is only software related). I'm getting over 3 weeks on my Tactix 7 (with regular GPS activities it is about 14 days), with everything on except the pulse Ox. Even with the custom watch face, with permanent second hand.
What is the benefit from wearing a sport watch on each of your wrist?
