vivoactive 6 Garmin finally learns to wake you gently

What is new about the vivoactive 6?

From the outside, very little. Garmin revealed the vivoactive 6 on 1 April 2025, and TechRadar noted at launch that it shares the dimensions and 1.2 inch screen of the vivoactive 5. The changes are inside the software. The headline addition is a smart wake alarm, which picks a moment in a light sleep phase within a window you set. It was new to Garmin's range at launch, and it is the kind of feature owners had been asking for for years.

The vivoactive 6 also gains Running Dynamics metrics, previously kept for Garmin's running watches, plus daily suggested walking workouts, on-screen workout animations with a muscle map, and Garmin Coach plans for running and strength. Garmin lists more than 80 activity profiles, from pickleball and padel to rucking and wheelchair pushes, and 8 GB of storage for music.

This version, part number 010-02985-01, pairs a Lunar Gold anodised aluminium bezel with a Bone case and matching silicone band. The other colours are Slate with Black, Jasper Green and Pink Dawn.

How big is it, and how will it wear?

Garmin quotes 42.2 x 42.2 x 10.9 mm and a weight of 23 g for the watch alone, or 36 g with the band. That is very light for a GPS watch with an AMOLED screen. Garmin says the band fits wrists of 125 to 190 mm in circumference, so it should work on most wrists, including small ones.

The bands use standard 20 mm quick release pins, so you can swap in any 20 mm strap. T3's reviewer found the silicone band comfortable but said a textile strap suits sleep and sweaty sessions better. That is worth noting if you plan to wear it overnight for the sleep features.

What does it track, and how long does the battery last?

The sensor list is broad for the price: GPS with GLONASS, Galileo, QZSS and BeiDou, Garmin's Elevate wrist heart rate sensor, Pulse Ox, a compass, a gyroscope and an ambient light sensor. There is no multi-band GPS, which OutdoorGearLab says matters more on trails under trees or in canyons than on open roads. You also get Body Battery, HRV Status, sleep coaching, incident detection, Garmin Pay and smart notifications.

Garmin claims up to 11 days in smartwatch mode, 5 days with the display always on, 21 days in battery saver mode and up to 21 hours of GPS. With music playing over GPS, that falls to 8 hours. Independent figures are less generous. T3's reviewer saw around five days on a charge with heavy use, and OutdoorGearLab measured 20 hours with GPS. Charging is quick, but it uses Garmin's own plug rather than a standard USB-C port on the watch.

How well is it built?

The case is fibre-reinforced polymer, topped by an anodised aluminium bezel and Corning Gorilla Glass 3. It is rated to 5 ATM, which Garmin describes as suitable for swimming, and there are pool and open water swim profiles. TechRadar notes it has just two buttons, so most control is by touchscreen. That keeps it neat, but buttons are easier to use mid-run with sweaty fingers.

The plastic case keeps the weight down. It will not feel as premium as a steel smartwatch, but it is also less likely to make you think twice before wearing it to the gym.

Is it good value against its rivals?

Garmin UK lists the vivoactive 6 at £269.99. TechRadar reported a launch price of £279.99, so it has eased slightly since. Its closest rival is in Garmin's own range: the Forerunner 170, which Garmin lists from £219.99. The Forerunner is the more running-focused of the two, while the vivoactive 6 leans towards everyday wear, gym work and a wider spread of sports.

Against Apple and Samsung smartwatches, the vivoactive 6 offers longer battery life between charges and Garmin's detailed training data. It has a smaller app library and fewer smart features. T3 notes that iPhone users miss out on a few perks: Garmin lists text replies and viewing images from notifications as Android only.

What is the catch?

Two things. First, battery life is fine for a smartwatch but short for a Garmin, especially with the always-on display, music or heavy use. Second, the screen. Several owners on Garmin's own forum complain that automatic dimming in dark rooms cannot be switched off and makes the screen hard to read, and others report the display waking on movement even with gestures disabled. Firmware updates may change this, but check the forum threads before you buy if you often glance at your watch in the dark.

If those do not worry you, the vivoactive 6 packs most of what a casual athlete needs into a light, discreet case.

“A light, discreet watch that wakes you gently, as long as you can live with charging it every week or so.”
