Does disabling Screen cast affect battery life?

Yes, slightly. When enabled, the phone periodically scans for nearby cast receivers, which uses a small amount of background power. Disabling it under Cast stops that scanning.

Can I cast to a device on mobile data instead of Wi-Fi?

No. Screen cast requires both devices to share the same local Wi-Fi network; a mobile data connection alone will not allow mirroring.

Why did Screen cast turn off after a system update?

Some updates reset connectivity toggles to their default state. Reopen Bluetooth & device connection ➔ Cast and enable Screen cast/Wireless display again.

Is Screen cast the same as Bluetooth pairing?

No. Screen cast mirrors the display over Wi-Fi, while Bluetooth is used for audio or file transfer. They are separate connections even though both toggles sit in the same settings menu.

OnePlus: Turn Screen Cast On or Off

If your OnePlus phone won't show up when you try to mirror the display to a smart TV, monitor or Fire TV Stick, the Screen cast function is often switched off or blocked by a network mismatch. Wireless mirroring only works when both devices sit on the same Wi-Fi network, so a hidden toggle or a wrong network can quietly break the connection. Some OnePlus units also link this feature to a separate casting toggle, which adds another spot where it can get disabled.

Enable or Disable Screen Cast auf OnePlus

Screen cast on OnePlus phones mirrors your display to a TV, monitor or streaming stick over the local Wi-Fi network. It relies on the Wireless display protocol built into Android, so both the phone and the receiving device must be connected to the same network before a connection can be established.

If casting fails, the toggle for this feature is frequently the culprit. It can be switched off by default, disabled after a system update, or turned off accidentally from the quick settings panel.

To check or change the setting, go to Open the Settings ➔ Tap on Bluetooth & device connection ➔ Tap on Cast ➔ Enable or disable Screen cast/Wireless display.

Once enabled, your phone will search for nearby compatible receivers. If none appear, confirm that the target device also supports wireless display and sits on the identical network.

Turning the option off is useful when you want to stop background scanning for cast targets, which can have a small effect on battery life. If you only need occasional mirroring, leaving the toggle off until needed avoids unnecessary network scans.

Frequently asked questions

Both devices need to be on the same Wi-Fi network. Check the network name on your phone and on the TV or receiver, then confirm Screen cast is enabled under Bluetooth & device connection ➔ Cast.
