Similarities:

Garmin Quatix 8 and Fenix 8 (AMOLED versions) offer identical battery performance across both available sizes. The 47mm models deliver up to 16 days of battery life in standard smartwatch mode, around 7 days with the always-on display (AOD) enabled, and up to 47 hours in high-accuracy GPS mode.
