2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerAmazfit Balance vs OnePlus Watch 2
The Amazfit Balance is the smarter buy for those who prioritize lightweight design and wellness tracking. At just 1.23 oz, it’s incredibly easy to wear all day without feeling weighed down. However, if you're after premium features, the OnePlus Watch 2's 100-hour battery life and robust build might tempt you to spend more. Here's the key difference: Amazfit Balance offers a 475 mAh battery that lasts up to 14 days, while the OnePlus Watch 2 packs a 500 mAh battery with a staggering 100-hour lifespan. For daily use, that means fewer charging sessions with the OnePlus Watch 2, making it a better option for those who hate being tethered to a charger.
