Summary
Garmin’s Fenix 9 Pro Solar emerges as the stronger pick for buyers prioritizing solar endurance, with claimed battery life of up to 57 days in smartwatch mode and 1,000 GPS hours with sun.
That advantage comes from Garmin’s low-power MIP display and front solar ring that works while worn, while Amazfit’s brighter AMOLED drains too much power for solar to offset meaningfully.
Amazfit’s T-Rex Dual Solar counters with a sharper 3,000-nit AMOLED screen, lighter 69g weight and a much lower $649.99 price, versus $1,199.99 for the 51mm Garmin.
Its headline 51-day and 180-day figures rely on a rear solar panel that only helps off-wrist, limiting real-world gains during normal wear and GPS use.
The comparison frames the choice as endurance and deeper power-management tools on Garmin versus better everyday display quality and lower cost on Amazfit.
