Mi Watch — Frequently Asked Questions
Will the Xiaomi Mi Watch fit my wrist?
The Xiaomi Mi Watch looks balanced on flat wrist widths of roughly 56–76mm (about 15.0–20.3cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Xiaomi Mi Watch take?
22mm. Any 22mm strap fits, so you are not limited to Xiaomi's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Xiaomi Mi Watch battery last?
Between 50 hours and 528 hours per charge, depending on the power mode. Xiaomi rates Battery Saver at 528 hours and GPS at 50 hours; the chart above lists all 4 modes.
How does the Xiaomi Mi Watch battery compare with other Xiaomi watches?
At 16 days in everyday use it ranks #5 of the 32 Xiaomi watches in our database — the top 16% of the range. The full ranking, including GPS and power-saving figures, is on our Xiaomi battery life comparison.
Is the Xiaomi Mi Watch thick for a 46mm watch?
At 11.8mm, thinner than 82% of 46mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Xiaomi Mi Watch?
Honor Watch 5 Pro - Bluetooth, Huawei Watch GT 6 - 46mm, Samsung Galaxy Watch8 LTE Classic, Garmin Descent™ G2 all sit within half a millimetre of the Xiaomi Mi Watch's 45.9mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Xiaomi Mi Watch?
53.3mm, against a 45.9mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
