I switched from the Fenix 7x to the Epix 2 Pro. I found that the Fenix is much better performing than the Epix Pro.
Incoming notifications are displayed on the Epix at only about 10-15 fps. Everything jerks and is anything but fluid. Frame drops also occur when quickly scrolling through or reading notifications. Activating the torch by double-clicking on the Epix also takes much longer than on the Fenix. On the Fenix, the flashlight comes on immediately after the second click, whereas on the Epix, the flashlight only lights up when the hand is long gone.
I am aware that a higher clock speed of the CPU causes higher battery consumption. But I'm really unhappy with the Epix Pro right now because of the jerky behaviour. I wish Garmin could add an option under power settings to increase CPU at the expense of battery. I would be too happy to trade 1 week of runtime for good performance! Currently I absolutely regret of buying the epix instead of the fenix as I cant send it back (bought at reseller)
P.S: A standard dial has always been used.
