Amazfit Band 7 / Active 2 vs Apple Watch SE (2nd Gen)

The Amazfit's 18-day battery versus the Apple Watch SE's daily charging requirement is the single biggest practical difference between these two devices. With the SE, charging becomes a nightly ritual — forget once and you're tracking nothing tomorrow. With the Amazfit, you charge it roughly when you do laundry. For sleep tracking, multi-day trips, or anyone who just hates cable management, this gap is decisive.

This sounds obvious but buyers miss it constantly. The Apple Watch SE handles notifications, Apple Pay, Siri, third-party apps, and phone calls from your wrist. The Amazfit does none of that meaningfully. If you want your watch to replace phone interactions throughout the day, the Amazfit will frustrate you. If you just want to know your heart rate and step count, you're paying $190 extra for features you'll ignore.

CNET's lab testing put Apple Watch heart rate accuracy at the top of the category — and that's not a vanity metric. If you're training in heart rate zones, a 5-10 BPM error changes your entire workout prescription. The Amazfit's heart rate and SpO2 tracking is solid for casual use, but it lags behind Apple and Garmin in rigorous testing. For serious runners or anyone following a structured training plan, this gap is real.

Zepp, Amazfit's companion app, gets the job done but it's noticeably less polished than Apple Health — and the third-party app story is almost nonexistent by comparison. Apple Watch SE plugs into Strava, Watchletic, MyFitnessPal, and hundreds of fitness apps natively. That ecosystem compounds over time: the more apps you use, the more the SE pulls ahead. If you're just checking steps and sleep, this doesn't matter. If you're building a fitness stack, it matters a lot.
