Amazfit Balance 3 (A2566): problems, parts and running costs
Checked: 2026-10-17
Summary
The recurring complaints are the large 48 mm case, a button-and-crown control layout that takes time to learn, a Zepp Health app that still needs polish, and optical heart rate that is less reliable during sharp effort. Running costs are essentially the watch itself, and it is a fitness watch first rather than a full smartwatch.
Common problems and fixes
- The case is large — the 48 mm size may not suit small wrists, and one outlet publishes 51.4 mm including the sensor; no fix was reported, so check wrist size before buying. [2]
- New controls take time to learn — the three-button-plus-crown layout needs a learning period; no fix was reported beyond practice. [2]
- Altitude drift versus Garmin — a discrepancy against Garmin was observed; Amazfit later pushed a firmware update claiming to optimize workout altitude accuracy. [2]
- App-platform depth is limited — it is not an Apple Watch or Wear OS-class platform, so expect fewer third-party apps. [2]
- USB-C cable is not in the box — Amazfit’s FAQ explains the package has a magnetic charging base and no USB Type-C cable. [1][5]

Yearly running cost
No subscription is noted in the sources reviewed, so the running cost is essentially the watch itself. [1][5]
When it is a good buy
Amazfit lists the Stainless Steel A2566 at $369.99, available from June 2, 2026, with the Titanium version at $449.99 in a lighter 55 g case. The value rests on battery, screen brightness, 64GB offline maps and HYROX tools, not on app depth. [5][3]
