What the published tests say
- Forerunner 970, DC Rainmaker (16/06/2025): with the always-on display the battery lasted about 2.5 days. The tester writes that Garmin watches with 1,000-nit displays and 45-47 mm cases usually last him 4-6 days in the same use.
- COROS Pace 4, DC Rainmaker (10/11/2025): he calls it a very good value watch. In open-water swimming the GPS track is "not too bad" but cuts a corner early on; for COROS, he says, that is a good result. On the bike ride the wrist heart rate is more variable.
- Forerunner 570: no full test read yet, only Garmin's release and spec page. We do not judge it.
How to read the data
- Battery hours from different brands are not comparable: GNSS mode, screen and sensors differ.
- The Pace 4 has a much lower launch price. DC Rainmaker calls it a fantastic bargain, but notes that the Forerunner 255 and Vivoactive 6 on sale can reach its price with more features. That is the tester's view, not our verdict.
- COROS is an emerging brand: the trademark owner is listed in Dongguan, China (Canadian trademark register).
