Bip S Lite — Frequently Asked Questions
Will the Amazfit Bip S Lite fit my wrist?

What size band does the Amazfit Bip S Lite take?

Between 30 days and 2160 hours per charge, depending on the power mode. Amazfit rates Battery Saver at 2160 hours and Smartwatch at 30 days; the chart above lists all 2 modes.
Is the Amazfit Bip S Lite 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 Lite?
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 Lite's 35.3mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Amazfit Bip S Lite?
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.
