Verdict: Garmin Venu 4 45mm ahead on 1 row, Garmin Venu 4 41mm on none

On the makers’ published figures, the Garmin Venu 4 45mm wins on battery life (maker's claim) (288 h against 240 h). One gap is borderline, a difference most people would not notice: weight (case only) (33 g against 38 g) for the Garmin Venu 4 41mm. The other 9 rows have no threshold or no direction to judge by, so nobody wins them.

Specifications

A win is marked only where the figures can be ranked and the gap is one you could notice on the wrist. A row the site has no threshold for says whether the two differ, and that it is not ranking them. = marks the same figure on both, ≠ not ranked a difference with no ranking. Every figure carries its source.
