Amazfit Cheetah 2 Ultra Review: 60 Hours of GPS, £600 Asking Price

Amazfit already makes a titanium running watch, the Cheetah 2 Pro, and it already makes a sapphire-screened all-rounder with more battery than the Pro for £80 less, the Balance 3. So the Cheetah 2 Ultra has a narrow job to do at £599.90: be the watch you'd wear for a 100km trail race and trust to still be recording at the finish.

On paper it does that. Amazfit's UK spec page lists 60 hours in accurate dual-band GPS mode, up to 80 hours in its ultra long-distance trail scenario, and 30 days of typical use from a 780mAh battery. The case is grade 5 titanium, 52g without the strap, with a 1.5in AMOLED under sapphire. Amazon UK sells it for £599.90, the same price Amazfit charges direct, and it went on sale in May 2026.

Who it's for

Trail and ultra runners. Amazfit says so itself, and the feature list backs it up: contour maps, a trail running mode that adjusts your load for gradient and terrain, a colour-coded elevation profile of the route ahead, and a flashlight with red and SOS modes for the hours after dark. If your longest run is a road half marathon, you're paying £230 over the Balance 3 for battery you'll never touch.

It isn't a swimmer's watch either. The 5 ATM rating is fine for a lake or a pool, but the cheaper Balance 3 and T-Rex 3 Pro are both 10 ATM, which feels backwards on the most expensive watch in the range.

Battery, and which number to believe

Amazfit publishes six different battery figures for this watch, and the Amazon listing quotes the two biggest. Here's how they line up: 60 hours in accurate GPS mode (dual-band, all six systems), 33 hours in "heavy trail running mode", 48 hours in a standard trail scenario, 80 in an ultra long-distance scenario, and 228 hours at maximum GPS battery life with accuracy turned down.

The 33 hour figure is the honest one for race planning. It assumes you're using the maps, the screen and the trail-specific features, which is what you'd actually do in a mountain ultra. That still covers the cutoff at most 100km events. Compare like with like and the gap to the Cheetah 2 Pro is big: 60 hours of accurate GPS against the Pro's 31. The 60 hour figure is for steady recording with the screen mostly off.

Day to day, 30 days typical use means charging once a month if you run four times a week. Heavy use halves that.

Maps and navigation

This is the clearest upgrade over the Cheetah 2 Pro. The Ultra carries full-colour contour maps rather than plain street and trail lines, so you can see a steep climb coming before your legs do. Turn-by-turn directions, automatic rerouting if you go off course, a points-of-interest search and a round-trip route generator are all on the watch, and none of it needs a subscription.

Offline maps on Amazfit watches used to be slow to redraw. The newer renderer on the Balance 3 and Ultra is quicker, and on a 1.5in screen at 3,000 nits the contour shading is actually readable in sunlight. Garmin's mapping is still better at the edges (course import, ClimbPro-style climb breakdowns), but the gap is smaller than the £600 price tag suggests.

Training data

The running metrics are the full Amazfit set: lactate threshold, running power, ground contact time, VO2 max trends, finish time prediction and gradient-adjusted pace. The trail running mode is the new part, applying a load factor for gradient, terrain resistance and vertical gain so that a slow, steep hour registers as the hard session it was.

HybridCharge ties training load, overnight recovery and daily stress into one readiness score, which is the same idea as Garmin's Training Readiness under a different name. It's useful for spotting when you've stacked too much volume, and it's no more magic than any other readiness score.

The heart rate still comes from a wrist sensor. A 2025 study against a Polar H10 chest strap found consumer wearables tracked well at rest and on steady treadmill work but lost accuracy badly during burpees (study on wearable heart rate accuracy). Steep hiking with poles is a similar problem for the wrist. If you pace ultras by heart rate, pair a strap; the watch accepts one over Bluetooth, and our heart rate monitor guide covers the options. Our heart rate zone training guide explains how to set the zones up.

Against the alternatives

Inside Amazfit's own range, the Balance 3 is the value pick: 41 hours of accurate GPS, 10 ATM, the same screen and maps, £369.90. The Cheetah 2 Pro is lighter and smaller but has half the GPS battery, which makes it the weaker buy now the Ultra exists. And the T-Rex 3 Pro remains the rugged option for people who want 10 ATM and buttons that work in gloves.

Outside it, the Garmin Forerunner 970 sits at a similar price and brings Garmin's training platform, which is still the better software by some distance. The COROS APEX 4 costs about £170 less and gives you most of the endurance for trail running, with COROS's cleaner app. We'd pick the Cheetah 2 Ultra over the COROS only if the sapphire AMOLED and colour contour maps matter to you.
