we have only been able to test the predecessor model so far. In the latest model from TicWatch, the battery is supposed to be even longer in Essential mode. Thus, the smartwatch lasts up to 45 days. Admittedly, only the most basic functions are available here.
Without power saving, the battery life drops to a still very good 72 hours, at least according to the manufacturer. The TicWatch Pro 3 Ultra is a rather chunky smartwatch that is designed for outdoor use. A good water resistance, as well as a certification according to the military standard MIL-STD-810G, are on board.
