Smartwatch sensors measure heart rate via optical PPG sensors on the wrist — accurate to within ±2–5 bpm at rest, less reliable during high-intensity exercise due to wrist movement. SpO2 (blood oxygen) is an estimate rather than clinical-grade measurement. Sleep stage tracking (light, deep, REM) is useful for identifying trends but less accurate than clinical sleep studies. GPS accuracy (where included) is strong for route and pace tracking outdoors.

Most smartwatches require a paired smartphone for full functionality — apps, notifications, setup, and syncing. Cellular (LTE/eSIM) models can make calls, stream music, and receive notifications independently without the phone nearby, but still need a phone for initial setup and app management. Non-cellular models must remain within Bluetooth range (typically 10–30m) of the phone to receive notifications and data.

Battery life varies dramatically by watch type. Smartwatches with AMOLED displays and full sensors (Apple Watch, Samsung Galaxy Watch) typically last 1–2 days. Fitness-focused watches with simpler displays (Amazfit, Garmin) deliver 7–21 days. Always-on display mode reduces battery by 20–40%. GPS-active workouts are the heaviest drain. Disabling always-on display is the most effective way to extend battery life on AMOLED watches.
