While this is a respectable figure, it does vary depending on your usage patterns. If you’re actively using GPS tracking, heart rate monitoring, and other features, you’ll likely get closer to 2-3 days of battery life.

Charging the Polar Unite is a breeze thanks to its proprietary charging cradle. Simply place the watch on the cradle, and it will begin charging. The full charge time takes about 1-2 hours, so you can quickly get your watch back up and running.
