Amazfit Balance vs Apple Watch Ultra 3
You'd expect the Amazfit Balance to dominate with its long battery life, but the Apple Watch Ultra 3's rugged build and superior display brightness change everything. The Amazfit Balance is the mid-range option here, offering a lightweight 1.23 oz design for those who prefer something less bulky. However, with a 3,000-nit display, the Ultra 3 crushes visibility in bright conditions, making it a game-changer for outdoor enthusiasts who need reliable performance in any light. In my testing, the Amazfit Balance shines with up to 14 days of battery life, ideal for extended use without frequent charging. In contrast, the Apple Watch Ultra 3 offers up to 36 hours under normal use, which is impressive but doesn't match the Amazfit's stamina. If you're into fitness tracking with advanced wellness features, the Balance's body composition analysis is a compelling benefit, but if you want a versatile smartwatch that pairs seamlessly with your iPhone, the Ultra 3's premium features are worth considering for everyday use.
