Frequently Asked Questions
Does the Garmin Venu 4 have a flashlight?
Yes. The Venu 4 45 mm has a built-in LED flashlight you can turn on from the wrist, handy for night runs and checking gear in low light.
Can I swim with the Venu 4, and can I take it diving?
The Venu 4 carries a 5 ATM water rating, so it handles swimming and showering. Garmin does not publish a dive depth rating or any dive modes for the Venu 4, so it is a fitness and health smartwatch rather than a dive computer. Use a dedicated dive computer for in-water depth and decompression tracking.
What health metrics does the Venu 4 track?
It tracks 24/7 wrist heart rate with HRV status, Pulse Ox blood oxygen spot checks, skin temperature, Body Battery energy and stress, plus advanced sleep tracking with sleep score, sleep stages, sleep alignment and consistency. An ECG app is available for users 22 and older, and Pulse Ox and ECG availability varies by region. Women's health tracking is also included.
What size bands fit the 45 mm Venu 4?
The 45 mm Venu 4 uses a 22 mm quick-release band, shipped as silicone, so any 22 mm quick-release silicone or leather strap will fit. The 45 mm case measures 45 x 45 x 12.5 mm and weighs 38 g bare, or 56 g with the band.
Review summary
Reviewers consistently rate this watch highly and say the health and fitness tracking works as expected, with accurate 24/7 heart rate, sleep, stress, Body Battery, Pulse Ox and HRV readings. Several point to long battery life, around 12 days in one case, and to taking calls from the wrist. The guided workout suggestions came up as a favorite feature, and owners describe the strap material as smooth and comfortable. Good to know that one buyer swapped the strap to preserve the original. A solid pick for anyone tracking daily health, sleep and training on one watch.
