MyKronoz battery life FAQ
Which MyKronoz watch has the longest battery life?
Two models share the longest everyday figure in our data, 5 days: ZeCircle2 Premium, ZeRound3. The typical MyKronoz sits at 3 days.
Which MyKronoz watch lasts longest with GPS on?
The ZeSport, rated for 7 hours of continuous tracking. GPS runtime is quoted separately from everyday runtime and the two rank differently, so a model that leads on days per charge is not automatically the one to take to a long event.
