A smartwatch is a wrist-worn computing device with a touchscreen, sensors, a battery and a wireless connection. It displays the time, shows phone notifications, runs apps, tracks activity and sleep, and can make contactless payments through NFC. Some models have cellular connectivity through an eSIM.
Why it matters
A smartwatch is a wearable that doubles as a remote for your phone, which can reduce how often you pick the phone up. It also carries trade-offs: battery life is typically measured in days rather than weeks, features depend on the paired phone's operating system, and the sensors collect personal data. Compatibility matters because some watches work fully only with iOS or Android, not both.
Example
Typical connectivity modes:
- Paired by Bluetooth: notifications and calls relay through the phone
- Wi-Fi: updates and app data when the phone is not nearby
- Cellular (optional): calls, messages and maps with no phone, at the cost of battery and a data plan
Common mistakes
- Buying a watch without checking phone compatibility.
- Letting every app send notifications to the wrist.
- Skipping software updates, which include security fixes.
