Disconnect Unused Bluetooth Devices
Bluetooth devices can connect when they are in the range of your phone and drain your battery without you knowing. Cameras, watches, speakers, earbuds, and more are the most common culprits.
- Open the Settings app.
- Go to Bluetooth.
- Find the Bluetooth device you want to remove and tap on the (i) button next to the name.
- Tap on Forget This Device to remove the device.
