Amazfit Sports Watches 2026: Reviews, Accuracy Tests and Buying Advice

Amazfit and Zepp Health

Amazfit is the consumer brand of Zepp Health (NYSE: ZEPP), formerly Huami Technology. The company began as a Xiaomi ecosystem partner, manufacturing the Mi Band series, launched the Amazfit Stratos as its first standalone multisport watch in 2018, and rebranded its companion app from Amazfit to Zepp in 2020. The corporate name followed in 2022. Zepp Health is headquartered in Hefei, China, with offices in Cupertino and Munich.

The brand spent its first five years competing on price alone. The Stratos was a credible triathlon watch with many features at a fraction of the Garmin Forerunner 935’s cost, but GPS accuracy and software maturity lagged. That changed in 2024 with the T-Rex 3, which delivered market-leading battery life and mapping at $279, and accelerated in 2026 with the Cheetah 2 Pro and Ultra, the first Amazfit watches to match Garmin and Polar references in controlled heart rate testing on this site.

The 2026 range spans six product families, from a $169 entry-level runner’s watch to a £599.90 titanium trail flagship. Average selling prices rose more than 20 per cent year-on-year in Q1 2026, and none of the seven 2026 launches has been discounted from MSRP. Amazfit is no longer a budget brand by default; whether the market accepts that repositioning remains an open question.

The 2026 product range

Balance series

The Balance 3 (from £369.90) and Balance Ultra (£599.90) sit at the top of Amazfit’s lifestyle-sport range. Both run Zepp OS 6 with HybridCharge (the readiness score that replaced BioCharge), HYROX workout tools, and Multi-Device Activity Sync. The Balance Ultra adds a titanium case and sapphire crystal. The Balance 2 (£299) remains in the range as the family’s entry point, with 14-day battery life and AI food logging via the Zepp app.

Cheetah series

The Cheetah 2 Pro (from £449.90) is Amazfit’s first serious dedicated running watch: it has a titanium bezel, a sapphire lens, dual-frequency GNSS, and Stryd compatibility via Bluetooth. It was tested for running, cycling, and swimming against Garmin, Polar, and Stryd references on this site. The Cheetah 2 Ultra (£599.90) adds trail-specific features, including an Elevation Overview tool that functions as Amazfit’s answer to Garmin ClimbPro, a brighter display, and improved GPS accuracy (85% on the standardised 10-mile test, up from 73% on the Pro). At £599.90, the Ultra is priced the same as the Garmin Forerunner 970.

T-Rex series

The T-Rex Ultra 2 is the outdoor and adventure flagship. It carries full topographic maps, dual-frequency GNSS, and a rugged MIL-STD-810H case. Testing on this site found it out-maps the Garmin Instinct 3 and undercuts the Garmin Fenix range on price. The T-Rex 3 and T-Rex 3 Pro remain available below it. The T-Rex 3 review on this site identified eight cons but concluded that the $279 value proposition was difficult to argue with.

Active series

The Active Max ($169) is the entry-level runner’s watch: 1.5-inch AMOLED display, 25-day battery life, HYROX support, NFC payments, and Stryd integration. It was awarded Editor’s Choice on this site as a budget alternative to Coros and Garmin.

Helio ecosystem

The Helio Strap is Amazfit’s screenless recovery band, positioned against Whoop at $99 with no subscription. The review on this site described it as a Whoop tickler rather than a Whoop killer: the hardware works, the software ecosystem does not yet match Whoop’s depth. A second-generation Helio Strap is confirmed for H2 2026, alongside a Helio Ring 2. The original Helio Ring faces an Oura patent infringement lawsuit targeting its curved battery and sensor placement design. Amazfit also sells a Helio Arm Sleeve accessory that repositions the strap sensor to the biceps for improved accuracy during exercise.

How Amazfit differentiates

Four factors separate Amazfit from the established running watch brands.

Price-to-feature ratio. Every Amazfit watch includes dual-frequency GNSS from the Cheetah 2 Pro upward, AMOLED displays across the range, and no subscription fees for any software feature. Garmin charges separately for Connect+ and secures features such as maps and ECG behind its highest-priced models. Amazfit includes offline maps with on-device re-routing on the T-Rex Ultra 2 at less than half the price of a Garmin Fenix 8.
HYROX licensing. Amazfit signed a three-year exclusive global partnership with HYROX in April 2026. The watches carry officially licensed HYROX workout modes, Training Focus metrics aligned to HYROX race demands, and branded competition tools. No other watch brand holds this licence. HYROX is the fastest-growing mass-participation fitness event format, and Amazfit is betting its premium repositioning on capturing that audience.
No subscription model. No Amazfit feature requires a recurring payment. HybridCharge, sleep staging, training load, AI food logging, and all health metrics are included. This is a direct contrast to Whoop (mandatory subscription), Garmin (Connect+ for advanced features), and Oura (membership for full ring analytics).
Software cadence. Zepp Health has accelerated its firmware release schedule since late 2025. The December 2025 update added rucking modes and Zepp OS 5 features to the T-Rex 3 and Helio Strap. The Q3 2026 roadmap confirms iOS Notification Forwarding under the EU Digital Markets Act, enhanced weather, optimised terrain map downloads, and improved navigation alerts across 19 products.

Zepp Health as a business

Zepp Health posted 33.8 per cent revenue growth in Q1 2026, with gross margins improving and losses narrowing. The share price fell 19 per cent in the five days following the earnings release. The balance sheet and the timeline to profitability explain the disconnect: Wall Street is not yet convinced the premium push will generate sustained earnings. Average selling prices have risen sharply, but the company remains loss-making, and the HYROX licence fee (undisclosed) adds a fixed cost commitment on top.

The 2026 product slate confirms at least 10 new launches. Seven had shipped by June. The Falcon 2, smart glasses, and a camera accessory have been hinted at but not confirmed with specifications. Amazfit’s three-year software support policy, quietly extended in early 2026, now covers the T-Rex 3, Balance 2 and several older models.

What the accuracy data shows

GPS and heart rate accuracy have been tested independently on this site across multiple Amazfit devices and sessions.

The Cheetah 2 Ultra scored 85 per cent on the standardised 10-mile GPS accuracy course, a meaningful improvement on the Cheetah 2 Pro’s 73 per cent. It remains behind the Forerunner 970 on the same course. A controlled track test of the Amazfit Balance 2 alongside the Forerunner 970, Apple Watch Ultra 3, and Huawei Runner 2 produced competitive distance accuracy from the Balance 2.

Heart rate results from the Cheetah 2 Ultra are the strongest Amazfit has produced. Five sessions from six scored Excellent against reference devices. A HYROX simulation at 33°C showed near-zero bias relative to the Whoop MG, Garmin HRM600, and Polar Verity SENSE. A road cycling sprint test returned ±3 bpm limits of agreement. A 150-minute endurance ride with the Helio Strap, alongside a Fourth Frontier ZONE ECG reference, showed competitive accuracy for the bicep-worn strap.

A separate meta-analysis of smartwatch AFib detection found Amazfit’s continuous PPG monitoring produced superior real-world diagnostic performance compared to Garmin’s manual ECG approach for detecting intermittent atrial fibrillation. The study measured population-level screening, not sport-specific accuracy.

Battery life on the Cheetah 2 Ultra is projected to be 55 hours of GPS runtime in a 100km Isle of Wight cycling test.

Software: Zepp OS and the Zepp app

Zepp OS 6 is the current operating system. The Zepp 10 app update (May 2026) replaced BioCharge and Readiness with HybridCharge, a readiness score that combines biometric sensor data with daily self-reported inputs (sleep quality, mood, perceived soreness). This is the first mainstream readiness score to use a hybrid biometric-plus-subjective approach, compared to the purely sensor-driven scores from Garmin Body Battery and Whoop Recovery.

Multi-Device Activity Sync, introduced with the Balance 3 and Balance Ultra, consolidates step and calorie counts across multiple Amazfit devices. It replicates what Garmin TrueUp has offered since 2016. Whether workout training load syncs across devices is not yet confirmed.

Voice memo recording, added to the T-Rex 3, T-Rex 3 Pro, and Active 2, tested at 98 per cent transcription accuracy on this site. Notes cannot be edited once recorded.

The HYROX partnership

The three-year exclusive global partnership, signed in April 2026, is Zepp Health’s most significant commercial bet. The licence grants Amazfit sole rights to HYROX-branded workout modes, race tools, and competition integration on a wrist-worn device. HYROX grew from a single event in Hamburg in 2017 to 130 events across 35 countries. No other watch brand can offer official HYROX tools.

The question is whether the investment pays off for a loss-making company. The analysis on this site examined whether it represents a smart investment or a Hail Mary. The answer depends on whether HYROX’s audience, which skews younger and more gym-oriented than the traditional endurance market, converts to Amazfit hardware purchases at the new, higher price points.

Ecosystem and integrations

Amazfit’s third-party integration is narrower than Garmin’s but has expanded. Stryd running power meters pair via Bluetooth to the Cheetah 2 Pro, Cheetah 2 Ultra, T-Rex 3, and Active Max. Manual calibration is required, but a test on this site confirmed indoor pacing accuracy suitable for HYROX racing. Activity sync to Strava runs automatically via the Zepp app. Apple Health and Google Health Connect sync is supported. There is no equivalent to Garmin’s Connect IQ app store or to the open third-party data field architecture. The Zepp app is the sole interface for all health, training, and device management functions.

Frequently asked questions

Does Xiaomi own Amazfit?

Not directly. Amazfit is the consumer brand of Zepp Health, a publicly traded company on the New York Stock Exchange (ticker: ZEPP). Zepp Health was formerly called Huami Technology and built the Xiaomi Mi Band under an OEM agreement. Xiaomi remains a minority shareholder but does not control the company. Zepp Health designs, manufactures and sells Amazfit products independently.

Is Amazfit accurate for running?

It depends on the model. The Cheetah 2 Ultra scored 85 per cent on this site’s standardised GPS accuracy test and returned five Excellent heart rate accuracy scores from six sessions against reference devices. Older and lower-priced models produce less consistent results. A chest strap or arm-worn optical sensor will outperform any wrist-based optical HR sensor during high-intensity intervals, regardless of brand.

Does Amazfit work with Strava?

Yes. Activities recorded on any current Amazfit watch sync automatically to Strava via the Zepp app. The sync is one-directional: activities flow from Zepp to Strava, not the reverse. Routes and structured workouts cannot be pushed from Strava to the watch.

Does Amazfit require a subscription?

No. Every Amazfit software feature, including HybridCharge readiness scores, sleep staging, training load, AI food logging, and HYROX workout tools, is included with the hardware purchase. There is no paid tier.

Which Amazfit watch has maps?

The T-Rex Ultra 2, T-Rex 3 Pro, and Cheetah 2 Ultra include downloadable offline topographic maps. The T-Rex 3 (non-Pro) and Balance series offer breadcrumb route navigation but not full map tiles. The Active series has no mapping.

Is the Amazfit Helio Strap a Whoop alternative?

In hardware terms, yes: the Helio Strap is a screenless optical HR band worn on the wrist or bicep, priced at $99 with no subscription. The review on this site found the sensor hardware competitive, but the Zepp app’s recovery analytics do not yet match Whoop’s depth in strain modelling, sleep coaching, or behavioural journaling. A second-generation Helio Strap is confirmed for H2 2026.
