How to Fix Common Smartwatch Problems (2026 Troubleshooting Guide)
Most smartwatch problems — won't connect or sync, notifications not coming through, battery draining fast, or the watch acting up — are fixed by a few simple steps: make sure Bluetooth is on and the watch is near your phone, check the companion app's permissions, restart both devices, and update the watch software. For stubborn problems, the reliable fix is to reset the watch and pair it fresh. Below are the common problems and how to fix each, starting with the easiest. Most issues come down to the connection, the companion app, or permissions.
Before you troubleshoot
- Charge the watch — some "faults" are just low battery.
- Make sure the companion app is installed and updated on your phone — it is central to the watch working.
- Keep the watch near the phone during troubleshooting.
Problem: watch won't connect or keeps disconnecting
- Make sure Bluetooth is on and the watch is within range of the phone.
- Open the companion app — many watches connect through it, so it may need to be open or running in the background.
- Restart both the phone and the watch — a simple restart clears many connection glitches.
- Keep the phone close — distance and obstacles cause drops.
- If it persists, reset the watch and pair fresh (see below).
Problem: notifications not coming through
This is one of the most common complaints, and it is almost always a permissions issue.
- Grant notification permission to the companion app, both in the app and in your phone's settings.
- Check which apps are allowed to send notifications to the watch in the companion app, and enable the ones you want.
- Make sure "Do Not Disturb" (on the phone or watch) is not silencing them.
- Confirm the watch is connected — notifications only come through when it is paired and in range.
Problem: watch won't sync data
- Open the companion app and make sure it is connected to the watch.
- Check Bluetooth is on and the watch is near the phone.
- Force a manual sync in the app if it offers one.
- Grant the app permissions for health/activity data so it can sync.
- Restart the app (close and reopen) or restart both devices.
Problem: battery draining fast
- Turn off the always-on display (a major drain) and use raise-to-wake.
- Lower brightness, limit GPS, and reduce notifications.
- Use battery-saver mode.
- If the watch is old and drains fast no matter what, the battery may be worn (see our battery guide).
Problem: watch is slow, frozen, or acting up
- Restart the watch — clears temporary glitches.
- Update the watch software via the app — updates fix bugs and improve performance.
- If it stays buggy, reset the watch and set it up fresh.
The reliable fix: reset and pair fresh
For stubborn problems that simple steps do not solve:
- Unpair/forget the watch in the companion app and your phone's Bluetooth.
- Factory reset the watch (in the watch's settings — check its guide for the exact steps).
- Set it up fresh from the start (see our setup guide).
A reset clears the slate and resolves most persistent connection, sync, and behaviour problems. You will need to redo setup, but it is the most dependable fix.

When it's genuinely faulty
If you have restarted, updated, and reset the watch and a problem persists — especially hardware issues like a sensor not working, the screen failing, or it not charging — it may be genuinely faulty. Check your warranty and contact the seller or service point with your proof of purchase. This is why buying with a clear warranty matters.
