Everything to Know Before Buying a Smart Watch

Smartwatches range from $50 fitness bands to $800 luxury devices. Here's how to avoid wasting money on the wrong one.

Phone Compatibility Is Non-Negotiable

Apple Watch only works with iPhone. Samsung Galaxy Watch works best with Samsung phones (full features) but supports all Android phones. Garmin and Fitbit work with both iOS and Android equally well. Check compatibility before falling in love with a model.

Health Features Vary Widely

All smartwatches track steps, heart rate, and sleep. Premium models add blood oxygen (SpO2), ECG, skin temperature, and body composition. Decide which health features you'll actually use — most people only look at step count and heart rate.

Battery Life: Days vs Hours

Apple Watch: ~18 hours (charge daily). Samsung Galaxy Watch: ~40 hours. Garmin: 5-29 days depending on model. If nightly charging annoys you, Apple Watch is the wrong choice.

GPS: Built-in vs Phone-Connected

Built-in GPS means the watch tracks your runs and rides without your phone. Connected GPS uses your phone's GPS signal, which means you must carry your phone. If you exercise without your phone, insist on built-in GPS.

Price Tiers

$50-150: Basic fitness tracking, notifications, 5-7 day battery. (Fitbit Charge 6, Amazfit) $200-350: Full smartwatch features, apps, payments. (Samsung Galaxy Watch 6, Apple Watch SE) $400-800: Premium build, advanced health sensors, extended battery. (Apple Watch Ultra 2, Garmin Fenix 8)
