Amazfit Cheetah 2 Ultra pushes further vs the Cheetah 2 Pro

Zepp Health has now made the Cheetah 2 Ultra official, and it lands as the more endurance-focused sibling to the Cheetah 2 Pro. The new model pushes the line further toward trail and ultra-distance running, while the Pro remains the lighter option for marathon and performance training.

Both watches are up on the Zepp Health website now. The Ultra comes in at $599 while the 2 Pro can be picked up for around $150 less.

The Ultra is built around longer distances

The clearest split is positioning. Zepp Health describes the Cheetah 2 Ultra as a watch built for trail runners dealing with prolonged exposure, unpredictable terrain and sustained load. That explains much of the hardware direction.

This is the model for people who want more screen space, more battery capacity, more storage and proper offline mapping support. The official listing also mentions full-colour contour maps, ultra-fast navigation and Trail Running mode with load settings, which gives the Ultra a much clearer outdoor identity than the standard Cheetah pitch.

The Cheetah 2 Pro sits in a slightly different lane. It is aimed more at marathon and performance running, with a lighter build and a display that is smaller but sharper on paper. So this is not simply a better versus worse comparison.

It looks more like Zepp Health has separated the Cheetah line into two flavours of serious running watch. One is built for longer trail efforts, while the other keeps the road-running focus.

The Ultra is heavier but not much larger

The Cheetah 2 Ultra measures 47.4 x 47.4mm across the case. Zepp Health lists the thickness as 15.6mm including the heart rate sensor and 13.3mm excluding it.

The Cheetah 2 Pro is very close in size. It measures 48 x 48mm across the case, with thickness listed at 15.6mm including the heart rate sensor and 13.2mm excluding it. So the two watches are almost identical on thickness, while the Pro is fractionally wider.

The bigger difference is weight. The Cheetah 2 Ultra weighs 52 grams without the strap, while the Cheetah 2 Pro comes in at 45.6 grams without the strap.

Zepp Health has also given the Ultra a 22mm strap setup. The official specs list black silicone and striped green nylon options, while the Pro uses a 20mm silicone strap with a classic pin buckle.

That wider strap fits the Ultra’s outdoor direction. A nylon option also makes sense for longer efforts, especially if you want something more breathable than silicone.

The display is bigger on the Ultra

The display is one of the easiest differences to understand. The Cheetah 2 Ultra has a 1.5 inch AMOLED screen with sapphire glass, a 480 x 480 resolution, 323 PPI and peak brightness of up to 3,000 nits.

The Cheetah 2 Pro has a 1.32 inch AMOLED screen with sapphire glass, a 466 x 466 resolution, 353 PPI and peak brightness of up to 3,000 nits. So the brightness figure is aligned, but the Ultra gives you the larger canvas.

That should help with maps, workout pages and glanceability during longer outdoor sessions. For a trail watch, that makes sense. More visible data on the wrist is useful when the terrain is uneven and stopping to fiddle with screens gets annoying fast.

Battery and storage are the big hardware wins

Battery is where the Ultra pulls ahead most clearly. It has a 780 mAh battery and is listed for up to 30 days of typical use, up to 60 hours in Accurate GPS mode, up to 33 hours in Trail Running mode and up to 228 hours in maximum GPS battery mode.

The Cheetah 2 Pro has a smaller 540 mAh battery. It is good for up to 20 days of typical use, up to 10 days of heavy use, up to 8 days with AOD enabled, up to 31 hours in Accurate GPS mode, up to 69 hours in GPS power saving mode and up to 99 hours in extended GPS mode.

So the Ultra still has the stronger endurance story, especially for long trail efforts. But the Pro is not weak on battery. It just sits in a more road-running and structured-training lane.

Storage also doubles. The Cheetah 2 Ultra has 64GB, while the Cheetah 2 Pro has 32GB. That gives the Ultra more room for maps, music and offline use.

The core platform looks very similar

A lot of the underlying hardware appears to be shared. Both watches use a BioTracker 6.0 PPG biometric sensor with 5PD and 2LED. Both also include acceleration, gyroscope, ambient light, geomagnetic, temperature and barometric altimeter sensors.

Satellite positioning also looks aligned. Both support dual-band positioning and six satellite positioning systems, so the Ultra does not appear to get a different GPS class on paper. The real difference is how long each watch can keep going while using those tools.

Connectivity is slightly different in the official spec sheets. The Cheetah 2 Ultra is listed with Bluetooth, BLE 5.2 and Wi-Fi 2.4GHz, while the Cheetah 2 Pro lists Bluetooth, BLE 5.3 and Wi-Fi 2.4GHz.

The same applies to the general hardware extras. Both watches include a red and white flashlight, microphone, speaker and linear motor, so the day-to-day control and utility setup looks broadly aligned.

The Ultra gets the fuller outdoor package

The official Cheetah 2 Ultra listing also gives it 180+ sports modes, while the Cheetah 2 Pro lists 170+. That difference is not huge on its own, but it does reinforce the same split seen elsewhere. The Ultra gets the broader outdoor package, while the Pro keeps the lighter road-running focus.

The running feature set is also broad. Zepp Health lists built-in running workouts, Zepp Coach running plans, lactate threshold, running power, ground contact time, running gear management, Track Run mode, smart trajectory correction and virtual pacer.

It also supports connection to peripheral workout devices, including heart rate belts, running power meters, cycling power meters, cycling speedometers and cycling cadence meters. Third-party syncing includes Runna, Strava, TrainingPeaks, Apple Health, Google Fit and Intervals.icu.

Which one looks more useful

Cheetah 2 Ultra is the one built for longer, rougher runs, where battery life, screen size, mapping and storage matter more than shaving off every gram. The 1.5 inch display, 780 mAh battery, 64GB of storage, 22mm strap, 180+ sports modes and 33 hours in Trail Running mode all point in the same direction.

Cheetah 2 Pro is the leaner road-running option. It is lighter, has the sharper display on paper and still keeps the same broad running toolkit and support for external sensors.

So the split is pretty clean. Cheetah 2 Ultra makes more sense if you want the Cheetah line pushed toward trails, ultras and longer outdoor sessions. Cheetah 2 Pro makes more sense if you want the lighter marathon-focused watch.

Both watches are up on the Zepp Health website now.
