FAQ
Which has better battery life, Coros Pace 3 or Coros Pace Pro?
The Pace 3 has the edge in smartwatch battery life, rated at 24 days versus 20 days on the Pace Pro. For GPS use, both are rated at 38 hours, so the main battery difference is in everyday smartwatch mode rather than workout tracking.
Is the Coros Pace Pro worth paying more for than the Pace 3?
It depends on whether you want the extra features. The Pace Pro costs $299 versus $229 for the Pace 3, and its main upgrade is an AMOLED touchscreen with offline maps.
