The quickest way to turn off Chromecast
The simplest method is to unplug the device from power. Chromecast has no power button—it is designed to stay plugged in and ready to receive a cast from your phone or computer. If you want to stop it from working, unplugging it is the fastest and most complete way to do that.
If you want to keep it plugged in but prevent it from being cast to, you can turn off the Wi-Fi on the Chromecast itself through the Google Home app. This disconnects it from your network without physically removing power.
Key Takeaways
- Chromecast has no power button; unplugging it from the outlet is the standard way to turn it off completely.
- You can disable Wi-Fi through the Google Home app to prevent casting without unplugging the device.
- Turning off Wi-Fi on your phone or computer stops casting to that specific device but does not turn off the Chromecast itself.
- Restarting your Chromecast through the Google Home app can fix connection problems without unplugging.
Disconnecting Chromecast from Wi-Fi using the Google Home app
Open the Google Home app on your phone or tablet. Find the Chromecast device in your list of connected devices and tap it. Tap the settings icon (the gear symbol in the upper right corner).
Scroll down and look for the Wi-Fi section. Tap "Forget network" or "Disconnect." The Chromecast will no longer be connected to your Wi-Fi, and no one will be able to cast to it until you reconnect it manually. The device itself remains powered on, but it is offline.
Restarting your Chromecast without unplugging
If your Chromecast is acting up or you want a fresh start without physically unplugging it, you can restart it through the Google Home app. Open the app, select your Chromecast device, and tap the settings icon.
Scroll to the bottom and tap "Restart." The device will reboot, which usually takes 30 seconds to a minute. This clears temporary glitches and reconnects it to your network automatically. It is useful if casting is slow or if the device stops responding to commands.
Stopping a cast in progress
If someone is actively casting to your Chromecast and you want to stop it when ready, you do not need to turn off the device. On the device that is casting (a phone, tablet, or computer), open the app that is sending the content and look for the cast icon—it usually looks like a rectangle with curved lines in the corner.
Tap the cast icon and select "Stop casting" or "Disconnect." The content will stop playing on your TV or speaker, but the Chromecast remains on and ready to receive a new cast. This is faster than unplugging if you just want to interrupt what is playing.
Turning off Wi-Fi on your phone or computer instead
If you want to prevent casting from your own device without affecting the Chromecast, straightforward turn off Wi-Fi on your phone, tablet, or computer. This disconnects you from the network, so you cannot cast to any device—including your Chromecast—until you turn Wi-Fi back on.
This does not turn off the Chromecast itself. Other people on your network can still cast to it. Use this method if you want temporary privacy or if you are leaving the house and do not want the device to be accessible.
What happens when you unplug Chromecast
When you unplug a Chromecast from power, it shuts down completely. It will not respond to any cast commands, and it will not appear in the Google Home app as an available device. The next time you plug it back in, it will take 30 to 60 seconds to boot up and reconnect to your Wi-Fi automatically (assuming your Wi-Fi is still on and the password has not changed).
Unplugging is safe and does not damage the device. There is no shutdown sequence to wait for—you can unplug it at any time. This is the method most people use if they want the Chromecast completely off, such as when leaving for vacation or if they are not using it for an extended period.
Frequently Asked Questions
Does Chromecast use power when it is plugged in but not casting?
Yes. Chromecast draws a small amount of power constantly so it can listen for cast commands from your network. If you want to eliminate power use entirely, unplugging it is the only option. The power draw is minimal—usually less than 2 watts—but it is not zero.
Can I turn off Chromecast from my TV remote?
No. Chromecast does not have a remote control or a power button. You control it only through the Google Home app or by unplugging it. If your Chromecast is connected to a TV, turning off the TV does not turn off the Chromecast—it remains powered and ready to cast.
What if I forget my Wi-Fi password after disconnecting Chromecast?
You will need to reconnect it manually. Unplug the Chromecast and plug it back in. It will enter setup mode and broadcast its own Wi-Fi network. Use the Google Home app to reconnect it to your home network, and you will be prompted to enter your Wi-Fi password at that time.
Does restarting Chromecast erase my settings?
No. Restarting through the Google Home app is a soft restart—it reboots the device but keeps your settings and network connection intact. Only a factory reset (which requires holding a button on the device itself for 10 seconds) erases settings.
