Third-party reviews

Based on 112,533 buyer reviews from online shops.
Reviews last updated: June 2026 · How we calculate this

What we like about Xiaomi Mi Band 3

  • Exceptional value for money compared to higher-end competitors
  • Excellent battery life, typically lasting between 7 to 20 days depending on usage
  • Waterproof design up to 50 metres, suitable for swimming and showering
  • Large, responsive OLED touchscreen for viewing notifications and weather
  • Comfortable, lightweight design that is suitable for all-day wear and sleep tracking

What we don't like about Xiaomi Mi Band 3

  • Poor screen visibility in direct sunlight
  • Occasional inaccuracies in heart rate and step tracking during high-intensity exercise
  • Fiddly charging process requiring the tracker to be removed from the silicone band
  • Lack of built-in GPS, requiring a connected smartphone for accurate distance tracking
  • Mi Fit companion app can be cumbersome for data exploration and lacks advanced insights

Verdict

The Xiaomi Mi Band 3 is a budget-friendly fitness tracker featuring a 0.78-inch OLED touchscreen with a 128 x 80 resolution and 5ATM water resistance, making it suitable for swimming up to 50 meters. Its core capabilities include a continuous heart rate monitor, sleep tracking, and basic smartphone notifications, all powered by a 110mAh battery that offers up to 20 days of standby time. Its primary advantages are its lightweight 20g design, highly affordable price point, and impressive battery longevity compared to more expensive competitors. However, notable drawbacks include poor display visibility under direct sunlight, a lack of built-in GPS, and a somewhat tedious charging process that requires removing the tracking capsule from the silicone strap.
