Wearable connectivity & compatibility#

1. My wearable disconnects during the night#

If your sleep graph shows red gaps or if the connection to your watch is lost overnight, it is usually because Android is killing one of the necessary background components.

To maintain a stable connection, all three of the following must be excluded from battery optimization:

  1. Sleep as Android
  2. Your watch’s companion app (e.g., Galaxy Wearable, Zepp, Garmin Connect, Pixel Watch app).
  3. Bluetooth System App (On some devices, you may need to show “System apps” in the battery settings to find this).
