The Xiaomi Smart Band 8 is an incremental upgrade over the Mi Band 7: both have a 1.62-inch AMOLED display and a 5ATM water-resistance rating, while Band 8 adds automatic brightness, more listed workout modes and options such as Pebble running mode and pendant wear. Band 7 remains a sensible choice if it costs less, you rely on Zepp Life, or you want to keep using its straps. Compare local prices and check the exact model edition before buying.
Key differences at a glance

Specifications and mode counts above come from Xiaomi Global Support and Xiaomi’s product pages; display measurements are reported by GSMArena. Workout-mode count alone does not establish better tracking accuracy. Xiaomi’s battery figures are manufacturer claims, not guaranteed results.
Display: same size, with Band 8 refinements
Both trackers have a 1.62-inch AMOLED display, so Band 8 does not offer a larger screen. Xiaomi lists automatic brightness for Band 8 but not Band 7. GSMArena reports a 60Hz refresh rate and 600-nit peak brightness for Band 8, compared with 30Hz on older Mi Bands; it describes scrolling as smoother. Those reported specifications do not mean every interaction or viewing condition will feel different to every wearer.
Battery life: compare the stated modes
Xiaomi quotes up to 16 days of typical use and 6 days with AOD for Band 8, versus up to 15 days typical and 3 days with AOD for Band 7. Actual battery life depends on settings and use, so treat these as manufacturer estimates rather than promises. GSMArena reports one Band 8 review unit lasted 7 days and 6 hours with health tracking enabled and AOD off; that single result is not a controlled comparison with Band 7.

Workouts and wearing options
Xiaomi lists 159 workout modes for Band 8 and 120 for Band 7. Band 8 also supports options Xiaomi lists as unavailable on Band 7, including Pebble mode and necklace mode. In Pebble mode, the Band 8 can be attached to a shoe with a compatible running clip. Consider these additions if you will use them; a larger mode count by itself does not show that measurements are more accurate.
Apps, straps and connectivity
Band 8 uses Mi Fitness, while Band 7 supports Mi Fitness or Zepp Life. If your existing setup depends on Zepp Life, that difference may matter more than Band 8’s newer features. Band 8’s attachment design is different, and GSMArena reports that Band 7 straps do not fit it. Check compatibility for any replacement strap or running clip before purchase.
Rank #2
Xiaomi lists Bluetooth 5.1 BLE for Band 8 and 5.2 BLE for Band 7. The version number alone does not establish which tracker will have better range or reliability in your circumstances.
GPS, NFC and water resistance
GSMArena’s international Band 8 review unit had no built-in GNSS or NFC and relied on a paired phone’s GPS for route data. Do not assume another regional edition has the same features—or that it has features the review unit lacked. Verify the precise model and supported services before buying, especially if standalone GPS or NFC payments are essential.

Both models are rated 5ATM. That shared rating does not establish suitability for every water activity; check Xiaomi’s guidance for the activity you have in mind.
Which one should you buy?
- Choose Band 8 if you want automatic brightness, the listed additional workout modes, or the option to use Pebble mode or pendant wear.
- Choose Band 7 if it is meaningfully cheaper, you want the option of Zepp Life, or you want to keep using Band 7 straps.
- Keep your Band 7 if it meets your needs; the shared display size and core features make the upgrade incremental rather than essential.
Before deciding, compare local prices, battery expectations for your chosen AOD and monitoring settings, app requirements, accessory compatibility, and the exact regional edition. Neither model is the universal best choice.
