How long does the battery last on the V5?

Your battery should last 7/8+ hours in GPS mode and 6/7+ hours in GPS+Track mode. If you are playing two rounds in a day on a single charge we do recommend using GPS only mode for at least one of the rounds. The battery level can be viewed by swiping left or right on the main clock face. Or in the game menu when playing a round. If the battery is low during a round the low battery icon will be displayed.
