Amazfit GTR 4 Review: 14 Day Battery and Dual Band GPS for Under $200
Key Features
1.43″ AMOLED Display
Big, bright round display at 466×466 resolution. Reads easily in direct sunlight and the always on display doesnt murder the battery like some competitors.
Dual Band GPS
Circularly polarized antenna for better accuracy in cities and under tree cover. Tracks runs and rides without the usual GPS drift you get from cheaper watches.
14 Day Battery
Two full weeks on a charge with normal use. Even with heavy GPS tracking, you’ll get about a week. Most smartwatches cant touch this.
BioTracker 4.0 Sensor
Upgraded PPG sensor collects 33% more data than the previous version. Tracks heart rate, SpO2, stress, and sleep stages continuously.
Our Experience
The GTR 4 sits in a weird sweet spot where it looks like a $400 watch but costs half that. The aluminum alloy build feels solid on the wrist, and the round AMOLED display is genuinely one of the better screens weve seen at this price. Colors pop, text is sharp, and the anti glare coating actually works outside.
GPS accuracy was solid for running and cycling. We compared it against a Garmin Forerunner on the same routes and the tracks were nearly identical, which is impressive for a watch at this price. The dual band antenna makes a real difference in urban environments where buildings mess with satellite signals. One thing we noticed: heart rate can lag a bit at the start of runs before it locks on, but once its going, its consistent.
Battery life lived up to the claim. We got 12 days with moderate use (notifications on, sleep tracking, a few GPS workouts). Thats genuinely enough to forget about charging, which changes how you use a smartwatch. The Zepp app isnt the prettiest thing in the world but it gets the job done for viewing your data.
Pros & Cons
What We Liked
- 14 day battery life that actually delivers close to that number
- Dual band GPS tracks accurately even between tall buildings
- Build quality feels premium for under $200
- 150+ sport modes covers basically any activity you can think of
Worth Knowing
- Heart rate can be slow to lock on during the first minute of exercise
- Zepp app is functional but not as polished as Garmin Connect or Apple Health
- No LTE option, so you need your phone for calls and messages
