The Amazfit GTR 4 delivers 80% of premium smartwatch features at 40% of the price. After 5 weeks of testing, this $200 device competes with watches costing $400+. If you can live without Apple/Google ecosystems and accept a learning curve with Zepp OS, you get exceptional battery life, comprehensive health tracking, and a gorgeous AMOLED display for half what big brands charge.
Overall Score
The GTR 4 looks like a $400 watch. The aluminum alloy case, sapphire-like glass (actually mineral crystal), and leather/silicone band options create a device that doesn't scream “budget.” The 46mm case is substantial but not overwhelming—lighter than comparable Garmin models.
The rotating crown provides tactile navigation through menus. It's not as refined as Apple's Digital Crown but feels premium compared to touchscreen-only competitors. The 1.43-inch AMOLED display is the star—vibrant colors, deep blacks, and outdoor visibility rivaling watches costing double.
Amazfit claims 14 days. Our real-world results:
Compare that to Apple Watch's 18-hour battery or Samsung's 40-hour stamina. The GTR 4 eliminates charging anxiety—perfect for weekend trips or forgetful chargers.
The GTR 4 features dual-band GPS (L1 + L5) and supports GPS, GLONASS, Galileo, BeiDou, and QZSS. Translation: fast satellite locks (5-8 seconds) and accurate route tracking even in urban canyons.
We compared 50+ miles of runs/rides against Garmin Forerunner 965. Distance accuracy: 99.2%. Route accuracy in dense tree cover: noticeably better than single-band competitors. Offline maps (downloadable via Zepp app) provide turn-by-turn navigation without phone connectivity.
The GTR 4 monitors virtually everything:
Heart rate accuracy during high-intensity intervals lags premium devices by 5-10 seconds. For steady-state cardio, it performs admirably. Sleep tracking detects sleep/wake reliably but struggles with stage accuracy compared to Oura or Fitbit.
The GTR 4 supports 150+ sports modes including eSports, chess, and fishing. Most users need 10-15 modes—but having options for uncommon activities (rock climbing, skiing, golf) is appreciated.
Auto-detection works for running, cycling, and swimming. Manual mode selection is required for everything else. The Strength Training mode automatically counts reps with 75% accuracy—behind Garmin's 80% but functional.
Here's the GTR 4's biggest weakness: Zepp OS. The interface is gorgeous—smooth animations, customizable watch faces, logical menu structure. But the app ecosystem is barren:
If you need extensive app support, buy Apple Watch or Galaxy Watch. If you use a smartwatch for fitness tracking, notifications, and time, Zepp OS is sufficient.

The GTR 4 handles phone calls via built-in speaker and microphone. Audio quality exceeded expectations—clear enough for outdoor calls, though you'll want privacy for longer conversations. We took 15+ test calls; only 2 required switching to phone for clarity.
Notifications appear reliably but interaction is limited. You can read messages, dismiss notifications, and send canned responses (Android only). No voice-to-text, no rich interactions, no app-specific actions. It's notification viewing, not notification management.
Here's where the GTR 4 wins: price-to-performance ratio.
| Feature | Amazfit GTR 4 ($200) | Apple Watch SE ($249) | Samsung Galaxy Watch 6 ($299) |
|---|---|---|---|
| Battery Life | 12 days | 18 hours | 40 hours |
| Display Quality | Excellent | Good | Excellent |
| GPS Accuracy | Dual-band | Single-band | Single-band |
| App Ecosystem | Minimal | Extensive | Extensive |
| Health Tracking | Good | Excellent | Excellent |
If you prioritize battery life, GPS accuracy, and display quality over apps and ecosystem integration, the GTR 4 delivers premium features at budget pricing.
The Amazfit GTR 4 is the best smartwatch for budget-conscious buyers who want comprehensive fitness tracking, marathon battery life, and a gorgeous display without $400+ premium prices. Accept the limited app ecosystem and you get 80% of flagship features at 40% of the cost.
Buy if: You want 10+ day battery life, prioritize fitness tracking over apps, use a smartwatch primarily for health/notifications, or refuse to pay $400+ for Apple/Samsung branding.
Skip if: You need extensive third-party apps, depend on voice assistants, are deeply embedded in Apple/Google ecosystems, or prioritize perfect health sensor accuracy.
Best Alternative: Garmin Venu 3 (better ecosystem, worse value) or Fitbit Versa 4 (better sleep tracking, worse battery).
Yes, via the Zepp app. You get activity tracking, notifications, and basic features, but limited notification interactions (no voice-to-text replies). Works better with Android due to deeper integration options.
Very limited selection. Zepp OS has roughly 20 apps (weather, calculator, compass, some games). No Spotify, no Strava auto-sync, no smart home controls. Focus is on built-in fitness features, not third-party ecosystem.
Good for the price: 94.1% accurate vs chest strap during moderate exercise. Lags during rapid heart rate changes (intervals) by 5-10 seconds. Not medical-grade but adequate for fitness tracking and trend analysis.
With moderate use (AOD off, 30min GPS daily, continuous HR): 12 days. Heavy use (AOD on, frequent GPS, many notifications): 8-9 days. Battery saver mode: 18+ days. Significantly better than Apple Watch (18 hours) or Samsung (40 hours).
