New Life for T-Rex 3, Helio & Balance 2

T-Rex 3 was released over a year ago and has just bagged a significant update. Not to be outdone, Amazfit’s Helio Strap (The Whoop wannabe) and Balance 2 have also received similar updates.

I don’t particularly want to give a running commentary on yet another company’s software release. Still, Amazfit’s cadence seems to have been upped in recent months…meaning it’s taking its watch and sport sensor range more seriously – even the slightly older models. The company sells good, reasonably cheap products that have now got just that little bit better. It makes me wonder what’s in store for next year (I know some of the plans…watch this space!).

For perspective, it’s worth noting that Garmin added its Jet Lag feature three years ago, and the brand is taking it seriously, as it did earlier this year, about inaccurate workout detection.

Here’s a summary of the recent changes.

T-Rex 3 (December 2025)

• Zepp OS 5 system upgrade
• BioCharge app for energy tracking
• New Rucking and Mountain Hiking modes
• Uphill alerts in navigation
• Integration with STRYD, TrainingPeaks, Intervals.icu
• Jet lag assistant and screenshot capability

Helio Strap (December 2025)

• 29 new workout modes, including pool swimming, rowing, and combat sports
• Customizable favourite workout lists
• Improved activity detection
• Enhanced Balance 2 connectivity

Balance 2 (November 2025)

• Adjustable font sizes
• Separate audio zone controls
• TrainingPeaks and Intervals.icu integration
• New ski machine workout mode
• Enhanced digital crown gestures
• Additional always-on display watch faces

The Case for Continuous Improvement

Amazfit’s near-monthly updates make for easy tech news stories, but only the most tech-dedicated customers will notice or use all the new features.

But this approach signals real long-term commitment—and that’s valuable to owners. In a year, many will look back and think: yeah, my watch is noticeably more capable now. That might deter a few from upgrading to the latest Amazfit model, but not many. More importantly, it builds strong brand loyalty. The best recommendations always come from friends who are happy customers, not reviews or sites like this.
