The strength-enhanced design of the body details and internal structure takes into account a sense of both strength and practicality, making it tough from the inside out, and making it a partner you can rely on. A new circuit design especially developed for Amazfit T-Rex, an advanced low power-consumption chip, and a deep power optimization give the Amazfit T-Rex a longer battery life.
