What the reviews support
Fitness tools and charging intervals are stronger reasons to choose it than third-party apps.

Garmin Venu 4 (45mm)
45mm 2025 model; not the 41mm battery specification
Roundup updated 2026-10-03 · 2 assessment sources
What reviewers found
Fitness and endurance ahead of a full app ecosystem
The 45mm Venu 4 suits someone who wants fitness tracking, longer battery life and a useful built-in flashlight. It is less compelling if a wide selection of apps or cellular independence is essential. There is no LTE or full-color mapping, so do not buy it as a substitute for every outdoor-focused Garmin.

What changes the experience
The LED flashlight adds a practical convenience, but does not justify the purchase by itself.
TechRadarTom’s GuideBefore you buy
If you need full maps or standalone cellular use, compare a different device rather than assuming all premium watches include them.

Garmin Venu 4 (45mm) review ↗
The review tests a 41mm lunar-gold watch and favors its fitness features. The table also lists 45mm specifications; 41mm endurance is not a 45mm result.
