Is the Amazfit Cheetah 2 Ultra worth £150 more than the Cheetah 2 Pro?

For trail runners, yes — Trail Running mode, full-colour contour maps, and the Elevation Overview are exclusive to the Ultra, as is the 780 mAh battery that projects to 55 hours of GPS. For road runners, no. The feature set is identical, and the Pro’s 31-hour GPS claim is sufficient for almost any road event. The Ultra also has a larger, better-proportioned display, which matters if you wear the watch all day.

How does the Amazfit Cheetah 2 Ultra compare to the Garmin Forerunner 970?

At the same price, the FR970 leads in GPS accuracy (92% vs 85%) and trail software depth — PacePro, ClimbPro, and UltraRun aid-station support are more mature than Amazfit’s equivalents. The Ultra leads in battery life (55hr GPS projection vs the FR970’s 26-hour GPS-only rating) and, arguably, in aesthetics. If raw performance data is the deciding factor, the FR970 wins. If battery and daily wearability matter, the Ultra makes a case.

Will the Cheetah 2 Pro get Trail Running mode via a firmware update?

Amazfit has not said. Trail Running mode, the full-colour contour maps, and faster map rendering may be gated to the HS3S chip in the Ultra rather than available to the HS3 chip in the Pro. It is also possible that the separation is a commercial rather than a hardware decision. Amazfit has not clarified either way.

What GPS chipset does the Amazfit Cheetah 2 Ultra use?

The chipset is suspected to be an Airoha dual-frequency unit, based on the watch’s behaviour in standardised GPS testing. Amazfit has not officially confirmed the chipset. Coros uses the same Airoha family and achieves 88% in this test, suggesting there is firmware scope for the Ultra to improve beyond its current 85%.

How accurate is the Amazfit Cheetah 2 Ultra heart rate?

Across six test sessions — road cycling, trail running, two HYROX simulations, a road bike sprint test, and a hard interval run — the Cheetah 2 Ultra returned five Excellent results and one Good. The Good result came during a stormy interval run, the hardest session in the series. In steady-state and moderate-intensity training, optical HR accuracy is reliable. For interval work at or above threshold, a chest strap remains the more dependable option.

Is the Amazfit Cheetah 2 Ultra waterproof?

The Cheetah 2 Ultra has a 5 ATM water resistance rating and supports swim tracking. Pool swimming was not tested as part of this review. For swim metric detail from the same Zepp platform, see the Cheetah 2 Pro review.
