|Sources: Amazon, ManufacturerAmazfit T-Rex 3 vs Amazfit Balance
Get the Amazfit T-Rex 3 unless you need a similar-weight design. It boasts a stunning 27-day battery life that easily outlasts the Amazfit Balance's 14 days, making it perfect for outdoor adventures without worrying about charging. In real-world use, the T-Rex 3's rugged build and bright 1.5" AMOLED display (2000 nits) shine during outdoor activities. Meanwhile, the Amazfit Balance offers health-focused features like body composition analysis, but its battery life drops significantly if you enable Always-On Display, going down to just 5 days.
