Amazfit T-Rex 2 vs Garmin Forerunner 265
The Verdict
Amazfit T-Rex 2 and Garmin Forerunner 265 target different priorities within the smartwatch space. The T-Rex 2 excels in battery endurance, delivering up to 24 days of typical use and 45 hours of GPS tracking compared to Forerunner 265's 13 days and 20 hours respectively. Its larger 47mm AMOLED display with 454x454 resolution appears sharper than the Forerunner's 46mm 416x416 panel. Build quality favors Amazfit slightly, with its heavier 66.5g construction (versus 47g) suggesting more rugged durability, plus superior 10ATM water resistance versus 5ATM. Health tracking is equivalent on both, featuring SpO2 and heart rate monitoring with sleep analysis, though neither includes ECG. Garmin Forerunner 265 justifies its $449 price through advanced connectivity: NFC, WiFi, and Garmin's Connect IQ ecosystem offer extensive app support and smartwatch features. Amazfit's Zepp OS is simpler but functional. For runners prioritizing battery life, durability, and value at $229, the T-Rex 2 wins decisively. Runners valuing connectivity, lighter weight, and Garmin's training ecosystem should accept the Forerunner's trade-offs. The T-Rex 2 delivers superior cost-to-spec ratio.
