What's Covered in This Amazfit GTR 4 Review
Amazfit GTR 4 Review: Quick Verdict
One-sentence verdict: The Amazfit GTR 4 pairs dual-band GPS and two-week battery life with a genuinely low price, making it one of the best Amazfit smartwatch options for cross-platform buyers.
Starting around $199, it undercuts both Apple and Samsung’s entries easily. Even so, it can’t quite match their app ecosystems. Consequently, that trade-off shows up mostly in third-party app selection. However, for core fitness and health tracking, it competes well above its price. So, if raw sensor accuracy matters most, skip ahead to our comparison section.

Amazfit GTR 4 Review Scorecard
Design & Comfort
The Amazfit GTR 4 ditched its predecessor’s curved display for flatter, sharper lines. Honestly, that change makes it look noticeably more premium. At 10.6mm thick, it sits comfortably flat against the wrist. Additionally, it weighs just 34 grams without the strap. Most wearers forget it’s there by lunchtime.
Colors and Build Quality
Amazfit offers this watch in Black, Racetrack Gray, and Vintage Brown Leather. Notably, that leather option looks genuinely upscale for the price. A slim aluminum frame keeps the overall design refined and light. The rotating crown and side button feel satisfying to use. Meanwhile, tempered glass on top resists everyday scuffs and scratches well. So, this watch holds up nicely to daily wear.
Display Quality
A 1.43-inch AMOLED panel dominates the GTR 4’s round face. Resolution lands at a sharp 466×466 pixels. Consequently, text, maps, and activity rings all look crisp. An always-on display option keeps the time visible without a wrist raise. Additionally, brightness holds up well under direct outdoor sunlight.
Everyday Readability
However, always-on mode does meaningfully shorten total battery life. That’s the one real trade-off worth knowing upfront. Still, the interface feels responsive and colorful throughout daily use. Widgets and watch faces swipe smoothly between screens. Overall, this display looks genuinely premium at this price point.
Amazfit GTR 4 Health Tracking
Here’s where this watch quietly punches above its price. Continuous heart rate monitoring runs around the clock automatically. Additionally, blood oxygen (SpO2) and stress-level tracking both come standard. Sleep quality tracking, meanwhile, breaks down stages with genuine detail. Over 150 sport modes cover everything from running to yoga.
What's Limited
However, heart rate accuracy dips somewhat during intense interval training. That’s a known limitation reviewers have flagged consistently. Additionally, there’s no ECG sensor for heart rhythm checks. Menstrual cycle tracking exists but relies on manual logging mostly. So, treat health data here as a helpful trend, not clinical-grade.
Amazfit GTR 4 Battery Life
Amazfit’s 475mAh battery is genuinely this watch’s standout feature. The company claims up to 14 days on typical use. In real-world testing, moderate users report closer to 12 days consistently. Heavy users running always-on display and frequent GPS still get roughly 7 days. That’s remarkable compared to most rivals in this price range.
Fast, Simple Charging
A full charge from empty takes about two hours total. Therefore, a quick overnight charge easily covers over a week of use. The magnetic charging cradle snaps on securely without any fuss. Consequently, you’ll rarely think about battery anxiety with this watch. So, if battery life is your top priority, this watch delivers.
Amazfit GTR 4 GPS Accuracy
Amazfit built dual-band GPS into the GTR 4, a genuine first for its category. Consequently, route tracking stays accurate even near tall buildings or dense trees. That upgrade noticeably beats older single-band GPS chips. However, outright pinpoint accuracy still trails dedicated Garmin devices slightly. Overall, most runners and hikers will find this more than sufficient.
The Zepp App Experience
Setup and syncing happen through Amazfit’s Zepp app. It works with both iOS and Android phones equally well. Unfortunately, the app store here offers far fewer third-party apps than Wear OS. Built-in Alexa support helps fill that gap somewhat, though. So, expect solid core features but limited extra customization.

Amazfit GTR 4 Care and Water Resistance
This watch carries a 5ATM and IP68 rating combined. Therefore, it comfortably handles rain, sweat, and pool swims. However, that rating still isn’t permanent over years of use. Notably, seals and gaskets wear down gradually with regular wear. So, rinse the watch after ocean swims or heavy sweating. Also, avoid soap and very hot water, since both weaken seals faster.
Charging stays simple with the included magnetic dock. Just place the watch down, and it aligns itself. Meanwhile, keep the charging pins clean and free of debris. Occasionally, update the Zepp app for the newest health features. Overall, this watch asks very little in daily upkeep.
