How the fit model works · Size chart for every wrist

The Active 2 in short

  • 29.5g on the wrist. Lighter than 100% of the 22 smartwatches 44mm across that we have weights for.
  • Between 21 hours and 19 days per charge depending on the power mode — battery saver at best, gps at worst.
  • Water rated to 5 ATM.
  • 1.32 inches AMOLED display, always-on capable.
  • Takes 20mm bands, so third-party straps fit without an adapter.

Active 2 — Frequently Asked Questions

Is the Amazfit Active 2 thick for a 44mm watch?

At 9.9mm, thinner than 86% of the 22 smartwatches 44mm across that we track, so it slides under a cuff more easily than most of its size.
