Amazfit T-Rex Dual Solar: AMOLED Screen Meets Dual Solar Panels, With Marginal Real-World Gains
Amazfit’s T-Rex Dual Solar pairs an AMOLED display with front and rear solar panels and introduces a Solar Boost mode, offering a novel power trick but only modest real-world gains. The watch is largely a T-Rex Ultra 2 with a smaller battery and display, a 50m depth rating, and a higher price, and overheating can limit solar benefits. In practical use, solar helps only a few percent of battery life (roughly 2–3% in smartwatch time; up to around 14% in certain sunny scenarios), making it more of a tech showcase than a compelling power solution for most users.
