Expert opinion
The COROS Pace 4 offers market-leading training features on the wrist. However its ecosystem off the wrist is not as good as Garmin’s, and its wrist-based abilities are best for in-sport usage rather than being a great all-day smartwatch like the Apple Watch. The Pace 4 is the watch you wear for your racing and training, then leave it in the drawer until next time. Apple is the priority for lifestyle, and Garmin is the priority for advanced, deep and integrated sports features.
The AMOLED panel runs at 390 x 390, roughly four times the resolution of the Pace 3’s memory-in-pixel screen, and the watch still returns 31 hours of dual-frequency recording and 41 hours on all systems. It launched with breadcrumb navigation only. A September 2026 firmware update, first released as a public beta, added offline maps with street names and points of interest, and the 4GB of storage limits how many regions fit. Contactless payment, streaming music and a third-party app store are absent. Sensor support is Bluetooth only, which matters to cyclists running ANT+ power meters. Optical heart rate holds well on the treadmill and in steady outdoor running, and under-reads on hill repetitions and on rides beyond two hours. The multisport profile and cycling power meter support are both present at a price where the Garmin Forerunner 165 has neither.

Battery life
COROS omits the Pace 4 from its published battery specifications table, which covers the Pace Pro, Pace 3, NOMAD, Apex 2, Apex 2 Pro and Vertix 2S. The figures below come from the official Pace 4 specification. The Pace 4 has no standard full GPS mode and no endurance mode.
| Mode | Battery life |
|---|---|
| Daily use and sleep tracking | 19 days, or 6 days with always-on display |
| High, all systems | 41 hours, or 30 hours with always-on display |
| High, all systems, with offline music | 14 hours |
| Max, dual frequency | 31 hours, or 24 hours with always-on display |
| Max, dual frequency, with offline music | 12 hours |
| Charging time | Under two hours |

In testing for the5krunner review, drain in Max mode with the always-on display enabled settles at roughly 4 per cent per hour, consistent with the published 24-hour figure.
