A light (23 g), fitness-first Garmin that lasted about a week per charge in Tom's Guide's month of testing, with reliable heart-rate, step and distance tracking, music storage and tap-to-pay. It has no altimeter, few third-party apps and no LTE, and about 1 in 9 Amazon ratings are 1 or 2 stars, with some owners reporting units that stop working or lose connection.
Common Garmin Vivoactive 6 problems
- Some units fail or lose connection
Amazon's review summary says customers disagree on reliability, with some reporting it stops working after a couple of months, and that connectivity and durability are mixed, including screen cracks after six months. One Amazon reviewer says Bluetooth disconnects often.
- Limited smart features and apps
Tom's Guide lists limited third-party apps and smart features as a con; there's no LTE option, and no onboard ECG or skin-temperature sensor.
- No altimeter; smart alarm needs work
Without an altimeter it undercounted climbs in Tom's Guide's tests (by about 14 ft against an Apple Watch SE and 34 ft against a Galaxy Watch 7). Tom's Guide found the Smart Alarm's 30-minute window too short and its vibrations jarring, and an Amazon reviewer also calls the smart alarm not great.
What owners like
- About a week per charge
Rated up to 11 days; Tom's Guide averaged about 7 days with sleep tracking and roughly 14 hours of GPS. Amazon's summary calls battery life excellent.
- Reliable fitness tracking
Tom's Guide found distance, steps, heart rate and pace reliable; it beat a Galaxy Watch 7 in a 6,500-step test and narrowly lost to an Apple Watch Series 10. Amazon owners praise its heart-rate and GPS tracking.
- Light, with music and payments
Tom's Guide says the 23 g, 42 mm watch felt comfier than most smartwatches it has tested, and it has 8 GB for music, Garmin Pay, Incident Detection and LiveTrack.

- You hike and want accurate elevation (no altimeter)

What experts say
- Tom's Guide (Vivoactive 6 review): 'Nearly everything I want in a smartwatch': comfortable, a week-plus of battery and useful safety tools, but limited apps, no altimeter and a Smart Alarm that needs fine-tuning.
- Tom's Guide: Also tested in its fitness-tracker guide (updated 2026-09-02): a fitness tracker in a smartwatch body focused on running; you're probably overpaying unless you run a lot.
