The software can be checked in hours: holding the UP / Settings / About button.
I upgraded to 5.10
The watch is charging for exactly one hour, detected three times. On the screen, the digit “runs” the battery, when it is charged, the battery divisions are all displayed, the screen without it did not check. I won’t say anything about express, I just ran it once.
