Bip S — Frequently Asked Questions
Will the Amazfit Bip S fit my wrist?
The Amazfit Bip S looks balanced on flat wrist widths of roughly 44–60mm (about 11.7–16.0cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Amazfit Bip S 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 S battery last?
Between 22 hours and 40 days per charge, depending on the power mode. Amazfit rates Smartwatch at 40 days and GPS at 22 hours; the chart above lists all 2 modes.
Is the Amazfit Bip S thick for a 35mm watch?
At 11.4mm, thicker than 80% of 35mm 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 S?
Apple Watch Series 11 - GPS + Cellular · Titanium · 42mm, Certina DS Action Quartz 34.5 Stainless Steel - Yellow Gold / MOP / Bracelet, Tissot PRX Quartz 35 Stainless Steel / Red, Garmin Lily® 2 all sit within half a millimetre of the Amazfit Bip S's 35.3mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Amazfit Bip S?
42mm, against a 35.3mm 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.
