There are a few potential causes for your PS4 controller disconnecting from your phone. One possibility is that the controller is not properly connecting to your phone. If you have trouble connecting the controller to your phone, try resetting it and/or purchasing a new one. Another possibility is that the battery on your controller has low power. If this is the case, you may need to charge the battery before playing games or using other features of your PS4. Finally, you could be experiencing issues with Bluetooth connection. If this is the case, make sure that you are using the correct Bluetooth connection type and settings for your device.
