Why buy each?

Amazfit Band 7

18-day battery at under $50

18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.

Alexa built-in

Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.

PAI health scoring

Amazfit's Personal Activity Intelligence score aggregates your daily activity into a single 0–100 health index, guiding you toward optimal activity levels.

Xiaomi Watch

6-day battery on Wear OS

Dual-chip design keeps the main Snapdragon W5 dormant during light tasks, dramatically extending battery life beyond any rival Wear OS watch.

Wear OS 6 with ECG and eSIM

First Wear OS 6 device on the market — with ECG monitoring, EMG gesture control, and eSIM for standalone calling.

1.54" AMOLED at a competitive price

Larger and brighter display than Galaxy Watch 8 or Pixel Watch 4, with Hasselblad-tuned health sensors, starting at around $285.
