Bip U Pro — Frequently Asked Questions
Will the Amazfit Bip U Pro fit my wrist?
The Amazfit Bip U Pro looks balanced on flat wrist widths of roughly 43–58mm (about 11.5–15.5cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Amazfit Bip U Pro take?
20mm. Any 20mm strap fits, so you are not limited to Amazfit's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Amazfit Bip U Pro battery last?
Amazfit rates it at 9 days per charge in everyday use.
Is the Amazfit Bip U Pro thick for a 36mm watch?
At 11.4mm, thicker than 76% of 36mm watches — it will sit noticeably high on the wrist. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Amazfit Bip U Pro?
Zenith Defy Skyline 36 Stainless Steel - Diamond / Silver, Apple Watch Series 11 - GPS + Cellular · Aluminium · 42mm, TAG Heuer Aquaracer Professional 300 36 Stainless Steel / Blue Gradient - Diamond / Rubber, Tissot Seastar 1000 36 Quartz Stainless Steel - Rose Gold / Black / Bracelet all sit within half a millimetre of the Amazfit Bip U Pro's 35.5mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Amazfit Bip U Pro?
40.9mm, against a 35.5mm 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.
