GTS 4 Mini — Frequently Asked Questions
Will the Amazfit GTS 4 Mini fit my wrist?
The Amazfit GTS 4 Mini 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 GTS 4 Mini 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 GTS 4 Mini battery last?
Between 21 hours and 15 days per charge, depending on the power mode. Amazfit rates Smartwatch at 15 days and GPS at 21 hours; the chart above lists all 2 modes.
Is the Amazfit GTS 4 Mini thick for a 37mm watch?
At 9.1mm, thinner than 100% of 37mm 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 Amazfit GTS 4 Mini?
Zenith Defy A3643 Revival, Omega Museum Collection Seamaster Milano Cortina 2026 Winter Olympics, Kieslect Ks2, Noise ColorFit Icon 3 all sit within half a millimetre of the Amazfit GTS 4 Mini's 36.66mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Amazfit GTS 4 Mini?
41.8mm, against a 36.66mm 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.
