Amazfit Cheetah 2 Ultra gets HYROX tools and Zepp OS 6

Amazfit Cheetah 2 Ultra is receiving firmware version 6.1.114.1, a 20.10MB update with new HYROX tools, a HybridCharge upgrade, route preview and mapping tweaks. This appears to be the first official Zepp OS 6 release for the watch, although availability still varies by region.  

Hyrox is the main story

The biggest addition is HYROX support. The update adds an official HYROX workout library in the Zepp Health app, with templates that can sync to the watch for dedicated training sessions.

That gives Cheetah 2 Ultra owners a more structured way to prepare for the race format. Instead of treating HYROX as a generic workout, the watch can now work around the specific demands of the event.

HYROX Virtual Pace is probably the most interesting part. The feature generates a race strategy based on the conditions of the competition venue, then lets users adjust target times for each segment and see whether they are ahead or behind during the session.

Zepp Health has also added HYROX simulation training. This supports full race, half race, first half, second half and custom modes, which should help users practise parts of the format without always committing to a complete race simulation.

On this topic, earlier today Zepp Health held an event ahead of the HYROX World Championships in Stockholm. It showcased the new hybrid training system, along with the newly launched Amazfit Balance 3 and Ultra.

HybridCharge gets smarter

The update also brings a fully upgraded version of HybridCharge. This builds on the original BioCharge concept with more advanced calculation logic and intelligent scheduling. The point is to make the score adapt better to different sports and daily scenarios.

There is also a wording change around recovery. The watch now refers to “recommended rest time before your next high, medium or low intensity workout”, which is clearer than a simple full recovery time label.

Navigation gets a small visual upgrade

Route preview has been added to navigation. When selecting a route, the watch now shows a preview image on the workout preparation page before the activity starts.

That should help avoid loading the wrong route, although early user feedback in the Reddit thread sounds lukewarm. One user said the feature does not get in the way, but also described it as not especially useful.  

The map scale display has also been improved during activities and inside the Map app. New scale levels include 75 metres, 200 metres, 750 metres, 2 kilometres and 8 kilometres, with imperial equivalents also added.

Topographic map display gets some attention too. The update improves how the background looks when map resources have not been downloaded and adjusts the display hierarchy of some map points.

Zepp OS 6 appears to be part of the package

The update also improves status indicator behaviour. After briefly appearing on the watch face, indicators now sit more consistently in the status area at the bottom centre of the Control Centre.

Zepp Health says it has also improved the fluidity and performance of certain applications. That is vague, but these small speed and interface fixes often make a watch feel better after a few days of use.

Finally, Zepp OS 6 is also part of the package. Which means Cheetah 2 Ultra has joined Balance 3 and Balance Ultra as the only Amazfit device to feature the latest version of the operating system. Other devices are due to join this list soon. According to the schedule, Bip Max should be next.
