COROS Pace 4 Review: AMOLED Display and 31-Hour GPS at $249

The COROS Pace 4 lands at $249 with an AMOLED display and up to 31 hours of dual-frequency GPS battery life. That spec sheet puts it in direct conversation with the Garmin Forerunner 165, which costs roughly the same but delivers a shorter GPS runtime and a less bright display in direct sunlight.

The AMOLED screen is the headline. COROS took their time getting here compared to Garmin and Apple, but the execution is clean. Visibility in outdoor conditions matters for trail runners and triathletes reading pace data mid-effort, and this panel holds up.

Battery is where the Pace 4 genuinely separates itself from the Forerunner 165. Thirty-one hours in dual-frequency GPS mode covers your longest ironman bike leg and then some. The FR165 caps out closer to 19 hours in GPS mode. For athletes training double sessions or racing long-course triathlon, that gap is real and practical.

The new Voice Pins and onboard microphone are a curiosity. Record audio notes mid-run without stopping to type. Whether that sticks as a useful feature or stays a novelty depends on your workflow, but it's a differentiator nothing else at this price point offers right now.

At $249, the Pace 4 is the clearest budget pick for runners and triathletes who want AMOLED brightness, serious GPS stamina, and COROS's clean training ecosystem. Not flawless. But for the price, nothing else is this complete.
