Garmin Venu 4 (45 mm) review

I haven't worn the Venu 4. This review comes from Garmin's product page plus what Which? and Android Central have published. Right now that adds up to very little. Garmin's page, read on November 7, 2026, confirms the 45 mm case and not much else.

The 45 mm model costs $549.99Not verifiedNot verified right now, checked November 1, 2026. The Venu 4 also comes in a 41 mm size.

What the tests say so far

Which? lists the 45 mm watch at 56.4 g, 46.6 mm wide and 13.8 mm thick. Its battery result and its verdict sit behind a paywall, so I can't pass either on.

Which? also prints a display size that doesn't match any other figure I found for this watch. I've left the screen size out until I can check it.

Android Central's review says the Venu 4 is heavier than the Venu 3. It gives no gram count. So I can't tell you whether you'd notice on your wrist.

The battery number I don't have

No outlet I found has published a battery measurement for the Venu 4, and I don't have Garmin's own claim either. I haven't read DC Rainmaker, Wirecutter or Tom's Guide on it. A test could be out there.

This bothers me. Battery life is the first thing I'd ask about any smartwatch, and here the one outlet with a result charges you to read it.

What I'd do with my own money

I'd wait. At this price ($549.99Not verifiedNot verified), I want to know how many days it goes between charges, and nobody I can quote has said.

If you sleep in your watch, read the size figures first. 13.8 mm is how far the 45 mm case sticks up off your wrist, per Which?. The 41 mm model is the obvious alternative, but I haven't found a weight or thickness for it anywhere, so I can't tell you what the smaller case saves.

Why there's no score

I don't score a watch without a battery result. This one gets a number once an outlet I can read and cite publishes one.
