The Moto 360 Generation 3 smartwatch has an incredibly fast charging duration. It takes the watch 60 mins to charge from 0% to 100%. This result, however, may vary slightly if the device is being used while it charges. Also, using a charger not approved by the manufacturer might cause slower charge, shorter battery life, and heating problems.
To see the battery level, slide a finger down the screen, from the top of the watch.
