Side-by-Side Comparison
| Spec | Amazfit T-Rex 3 Pro (48mm) | Garmin Forerunner 970 (47mm, titanium bezel) |
|---|---|---|
| Price | $399.99 | $749.99 |
| Release Year | 2025 | 2025 |
| Display | 1.5-in AMOLED, up to 3,000 nits, sapphire crystal lens, optional always-on | 1.4-in 454x454 AMOLED touchscreen with sapphire lens, optional always-on |
| Smartwatch Battery ( days) | 25✓ | 15 |
| Always-On Display Cost | Amazfit's 25-day figure is typical use; heavy use is rated 10 days and one reviewer measured about 18 days alongside 14 h of accurate GPS. Amazfit does not publish a separate always-on display figure. | 7 days with always-on display, and GPS drops from 26 h to 20 h / multiband from 21 h to 15 h. DC Rainmaker found default brightness burns battery 'at an astonishing speed' and recommends about one-third brightness. |
| Battery, Single-Band GPS ( h) | 85✓ | 26 |
| Battery, Multiband GPS ( h) | 38 | 21 (the5krunner spec sheet) / 19 (garminrumors spec wiki) — sources conflict |
| GNSS Bands | Dual-band (L1+L5) circularly-polarised GNSS. The 85 h headline is the power-saving GPS mode; the accurate dual-band mode is 37-38 h on the 48 mm and about 29 h on the 44 mm. | Multi-band L1+L5 (GPS, GLONASS, Galileo, BeiDou, QZSS) with SatIQ auto-selection |
| Onboard Maps | Free offline contour maps with turn-by-turn, POI search, round-trip routing and auto-rerouting — but you must select and download each map region inside the Zepp phone app and transfer it across. Android Police called the process 'messy and time-consuming' with vague instructions. | Full TopoActive topographic maps preloaded, free, with on-device routing and turn-by-turn, plus 2,000+ ski resorts and 43,000 golf courses in 32 GB |
| Music Storage | Onboard storage for sideloaded MP3 files played to Bluetooth headphones. No Spotify and no streaming services. | 32 GB, roughly 2,000 songs, offline Spotify / Amazon Music / Deezer plus sideloaded MP3 |
| Training Platform & Subscription | The Zepp app and core training/recovery metrics are free. Zepp Aura, the AI sleep and coaching layer, is a paid subscription; the training data itself is not gated behind it. | Garmin Connect is free and every core training metric — Training Readiness, Training Load, Training Status, HRV Status, Body Battery, recovery time — is Firstbeat-derived and free on the watch (Garmin bought Firstbeat in 2020). Connect+ is $6.99/mo or $69.99/yr and adds only AI wellness prompts, 3D maps, Trails+ routing, extra badges and nutrition logging — nothing a training plan depends on. But Running Economy and Step Speed Loss — two of the 970's headline new metrics — do not work from the wrist at all: they require the separate HRM-600 chest strap, which DC Rainmaker calls an upsell. |
| External Sensor Support | Bluetooth only — no ANT+. BLE chest straps and Stryd pods pair through Zepp OS. | ANT+ and Bluetooth; HRM-200/HRM-600 straps, Stryd, power meters, Varia radar |
| Data Export | Free sync to Strava, adidas Running, Apple Health and Google Health Connect, plus a TrainingPeaks Zepp OS app; .FIT export via the Zepp app | Full .FIT file access over USB/MTP plus free automatic sync to Strava, TrainingPeaks, Runalyze, intervals.icu and others through Garmin Connect. |
| Warranty | 12 months | 12 months |

Pros & Cons
Amazfit T-Rex 3 Pro (48mm)
Pros
- +38 h of dual-band GPS and 25 days of typical use for $399.99 — Garmin charges $1,199.99 for 30 h of multiband
- +A 3,000-nit AMOLED behind sapphire with a titanium-alloy bezel at half the price of rivals with those materials
- +Free offline contour maps with genuine auto-rerouting, which even the $749.99 Forerunner 970 does not beat on price
- +10 ATM plus EN13319 freediving certification to 45 m, unusual at any price
Cons
- −Maps must be picked and downloaded region-by-region in the Zepp phone app then transferred — reviewers describe the process as messy and poorly documented
- −The 85 h battery headline is the power-saving GPS mode; the dual-band mode you would actually race on is 38 h
- −No ANT+ and no Spotify or any streaming service — sideloaded MP3 only
- −Zepp's software ecosystem and analytics are a clear step behind Garmin and COROS, and the app is cluttered
- −48 mm and chunky; reviewers found it too bulky for 24-hour wear
Garmin Forerunner 970 (47mm, titanium bezel)
Pros
- +Real preloaded TopoActive maps with routing, not a breadcrumb — the reason to step up from the 570
- +Multi-band GNSS plus SatIQ gives one of the most reliable traces in the category
- +ECG, skin temperature, flashlight and a sapphire/titanium build in a 56 g case
- +Deepest free training stack of any watch here — Training Readiness, Load, HRV Status and Garmin Coach cost nothing
Cons
- −Multiband battery is 21 h at most, and 15 h with always-on: the display, not the GNSS chip, is what kills it
- −Running Economy and Step Speed Loss require the extra HRM-600 chest strap — the watch alone cannot produce them
- −Sources disagree on the multiband figure (21 h vs 19 h), which is exactly the spec most buyers compare on
- −$749.99 buys less GPS runtime than a $429 Coros Apex 4 gives in its most accurate mode
- −DC Rainmaker recorded open-water swim HR errors not typical of previous Garmins
