How to charge Amazfit Stratos?
Amazfit Stratos contains a Lithium Polymer battery. All Stratos watches ship with the battery charged. However, we suggest fully charging your watch before use. It takes 2-3 hour to fully charge Stratos. To charge, attach the watch to the charging base, attach the USB end of the charger to your PC or a normal charging adapter. Make sure to align the 4 charging pins on the backside of the watch with the ones on the charging base. Once clipped-in, the watch face will light up and show that the watch as ‘charging’.
