My smartwatch keeps disconnecting from Bluetooth: what should I do?Updated 6 days ago
📶 Why does my watch disconnect?
Most disconnections come from the phone, not the watch: the system puts the ICE app to sleep to save battery, or the Bluetooth signal is disrupted.
💡 The ICE Kids 4G does not use Bluetooth: it has its own 4G connection. This article does not apply to it.
✅ Quick checks
- Don't close the ICE app (ICE Smart, ICE fit, ICE JUNIOR or ICE BAND) by swiping it away in recent apps: it must keep running in the background.
- Keep the watch and phone within 10 metres of each other, ideally with no wall in between.
- Make sure Bluetooth is on and the phone is not in aeroplane mode.
- Temporarily turn off your phone's battery saver mode.
- Make sure your ICE app is up to date.
On Android
- In Settings → Apps → your ICE app → Battery, choose "Unrestricted" (or disable battery optimisation).
- In Settings → Apps → your ICE app → Permissions, allow in particular "Nearby devices" and location.
- On some phones (Xiaomi, Huawei, Oppo…), lock the app in recent apps (padlock icon) so the system doesn't close it.
On iPhone
- In Settings → General → Background App Refresh, turn it on for your ICE app.
- In Settings → Privacy & Security → Bluetooth, check that your ICE app is allowed.
🔄 Reset the Bluetooth connection
If your watch has already been connected to your phone and keeps disconnecting, follow these steps in order:
- In your ICE app, remove the watch from the device list.
- In your phone's Bluetooth settings, forget the watch ("Forget this device").
- Reset the watch: Settings → Factory Reset.
- Reconnect the watch through the ICE app, not from your phone's Bluetooth settings.
- When your phone shows the Bluetooth pairing request, accept it.
How do I check that the connection is complete?
Swipe down on the watch screen and check that the call icon and the connection icon are both green. If they are, the watch is properly connected.
👧 ICE smart junior: these watches have no call function. Just check that the connection icon is green.
💡 If one of the icons is not green, pairing is not complete: repeat the procedure and make sure you accept the Bluetooth pairing request.
❓ Still disconnecting?
If you have followed all these steps and the watch keeps disconnecting, contact our customer service with your watch model, its 6-digit reference number (on the back of the box or on your invoice, more rarely on the back of the watch), your phone model and its iOS or Android version.
