I have a problem with my Steel HR Sport watch (40 mm). The watch is discharged and turned off. After placing it on the charging station, after 20 seconds the screen turns on and shows 0% battery. When I hold the button for about 15 seconds, the watch starts and shows 100% battery. When the watch is removed from the charging station, it switches off immediately. After putting it back on the charger, the situation is the same as at the beginning of the message.
How to fix this malfunction? Can the battery in this watch be replaced?
