How does GTR 4 compare with its closest competitors?

The Amazfit GTR 4 enters a competitive smartwatch market with strong contenders like the Huawei Watch GT 4 and the Samsung Galaxy Watch 4. Let’s see how they stack up:

Battery life

The Amazfit GTR 4 shines with its industry-leading 14-day battery life, significantly outperforming both the Huawei Watch GT 4 (up to a maximum of 14 days) and the Samsung Galaxy Watch 4 (up to 40 hours). This makes it ideal for users who prioritize extended use without frequent charging.

Health tracking

All three watches offer comprehensive health monitoring features. However, the Amazfit GTR 4 stands out with its BioTracker™ 4.0 sensor, which promises more precise data capture for heart rate, blood oxygen, and stress levels. 

While the Huawei Watch GT 4 boasts similar functionalities, user reviews suggest the Amazfit sensor might offer a slight edge in accuracy. 

The Galaxy Watch 4, on the other hand, takes the lead in advanced health features like ECG (electrocardiogram), appealing to users seeking a more comprehensive health picture.

Technology and user interface

The Huawei Watch GT 4 and Samsung Galaxy Watch 4 run on their respective proprietary operating systems, offering a wider range of apps and potentially smoother integration with their ecosystems (Huawei Health and Samsung Health, respectively). 

The Amazfit GTR 4 utilizes the Zepp OS, which is known for its user-friendliness but might have a narrower app selection compared to its competitors.

Design and compatibility

All three watches boast stylish designs, with the Amazfit GTR 4 offering a classic look, the Huawei Watch GT 4 catering to a more sporty aesthetic, and the Galaxy Watch 4 available in a wider variety of watch faces and straps. 

Compatibility-wise, the Amazfit GTR 4 and Huawei Watch GT 4 work seamlessly with both iOS and Android devices, while the Galaxy Watch 4 isn’t compatible with iOS functionalities.


The Amazfit GTR 4 generally falls within a slightly more affordable range compared to the Huawei Watch GT 4 and the Samsung Galaxy Watch 4. This makes it an attractive option for budget-conscious users seeking a feature-rich smartwatch.

Our verdict

The Amazfit GTR 4 emerges as a compelling option for health and fitness enthusiasts prioritizing long battery life and accurate activity tracking. 

Its BioTracker™ 4.0 sensor delivers reliable data on heart rate, blood oxygen, and sleep, while the multi-band GPS ensures precise workout tracking. 

The sleek design and comfortable build make it a wearable you’ll want to keep on throughout the day.

However, the Amazfit GTR 4 isn’t without limitations. The Zepp OS app selection might feel restrictive compared to competitors, and some smartwatch functionalities could be more polished.
