Casting from Chrome on Android uses the built-in Cast button in your browser

To cast a webpage or tab from Chrome on your Android phone or tablet, open Chrome, tap the three-dot menu in the top right corner, and select Cast. Your phone will search for nearby Chromecast devices on the same Wi-Fi network. Tap the device you want to cast to, and your screen will appear on the TV within a few seconds. The Cast button stays visible in your menu while casting is active, so you can disconnect just as quickly.

The process works the same whether you're casting a single tab, your entire screen, or just audio from a music or video app. Your Android device and Chromecast must be connected to the same Wi-Fi network for this to work—they don't need to be on the same network as your home router, but they do need to see each other wirelessly.

Key Takeaways

  • Open Chrome, tap the three-dot menu, and select Cast to see available devices on your Wi-Fi network.
  • Your Android phone and Chromecast device must be on the same Wi-Fi network to connect.
  • You can cast a single tab, your entire screen, or audio from apps like Spotify or YouTube Music.
  • Casting continues even if you lock your phone or switch to another app, so your TV stays uninterrupted.
  • Tap the Cast button again and select Disconnect to stop casting without unplugging anything.

What to do if the Cast button doesn't appear

If you don't see the Cast option in your Chrome menu, first check that both your phone and Chromecast are on the same Wi-Fi network. Open your phone's Wi-Fi settings and confirm the network name. Then go back to Chrome, close it completely, and reopen it. Sometimes the Cast button takes a moment to load.

If it still doesn't show up, restart your Chromecast device by unplugging it for 10 seconds and plugging it back in. Once it boots up and connects to Wi-Fi, open Chrome again and check the menu. If you're using an older version of Chrome, update it from the Google Play Store—the Cast feature works best on current versions.

Casting a single tab versus your entire screen

When you tap Cast and select your device, Chrome asks whether you want to cast a tab or your screen. Cast tab sends only the webpage or app you're currently viewing, and your phone stays responsive—you can lock it, switch apps, or even turn off the screen without interrupting what's on the TV. This is the most common choice for watching videos or browsing websites.

Cast screen mirrors everything on your phone's display, including notifications, your home screen, and any app you open. This uses more battery and bandwidth, but it's useful if you want to show someone a photo gallery, navigate a map, or demonstrate how to use an app. You can switch between tab and screen casting by tapping the Cast button again and selecting a different option.

Casting audio from music and podcast apps

Many music and podcast apps—including Spotify, YouTube Music, Google Podcasts, and Pandora—have their own Cast button built into the player, separate from Chrome's Cast menu. When you're playing a song or episode, look for the Cast icon (usually a rectangle with a Wi-Fi symbol) on the player controls. Tap it, select your Chromecast device, and the audio streams to your speakers.

This method is better than casting your entire screen because it uses less battery and lets your phone go to sleep without stopping the music. If you don't see a Cast button in your app, the app may not support Chromecast—in that case, you can cast the tab or screen from Chrome instead, though it will keep your phone awake.

Troubleshooting when your device won't connect

If your Chromecast device appears in the Cast menu but won't connect, first check that your phone and TV are on the same Wi-Fi network. Some home networks split devices between a 2.4 GHz and 5 GHz band—make sure both your phone and Chromecast are on the same band. You can check this in your Wi-Fi settings or your router's app.

If they're on the same network and still won't connect, restart both devices. Unplug your Chromecast for 10 seconds, plug it back in, and wait for it to fully boot. Then restart your phone's Wi-Fi by turning it off and back on in Settings. Try casting again. If the problem persists, restart your router by unplugging it for 30 seconds—this often clears connection issues that affect multiple devices.

What happens to your phone while casting

Once you've cast to your Chromecast, your phone becomes a remote control. You can lock the screen, switch to other apps, or even turn the phone off without stopping what's on the TV. The content streams directly from the internet to your Chromecast device, not through your phone, so your phone's battery drains much more slowly than it would if you were mirroring your entire screen.

If you're casting a tab and you close Chrome or force-close the app, the cast will stop. If you're casting audio from a music app, closing the app will also stop playback. But if you straightforward lock your phone or switch to another app, everything continues normally on the TV. This is why tab casting is so useful for long videos or music sessions.

Disconnecting from your Chromecast device

To stop casting, tap the Cast button in Chrome's menu again. You'll see your currently connected device listed at the top. Tap it and select Disconnect. The cast will end when ready, and your TV will return to whatever it was showing before you started casting. You don't need to unplug your Chromecast or do anything on the TV itself.

If you want to cast to a different device, you can also tap the Cast button, select a new device, and it will switch over. Your old cast will end automatically. There's no harm in leaving a Chromecast plugged in when you're not using it—it uses very little power and will be ready the next time you want to cast.

Frequently Asked Questions

Do I need a Google account to cast from Chrome?

No. Casting from Chrome to Chromecast works without signing into a Google account on your phone. However, if you want to cast content from apps like YouTube or Google Play Music, you may need to sign in to those services within the app itself.

Can I cast if my phone is on a different Wi-Fi network than my Chromecast?

No. Your phone and Chromecast must be on the same Wi-Fi network to connect. If you're away from home, you won't be able to cast unless you connect both devices to the same network—for example, a guest Wi-Fi or mobile hotspot.

Will casting drain my phone's battery quickly?

Casting a tab or audio uses very little battery because the content streams directly to your Chromecast. Casting your entire screen uses more battery because your phone's display stays active. If you're casting for a long time, plug your phone in or use tab casting instead of screen mirroring.

What if my Chromecast keeps disconnecting?

Restart your Chromecast by unplugging it for 10 seconds and plugging it back in. If it keeps disconnecting, move your Chromecast closer to your router or away from other electronics that might interfere with Wi-Fi. You can also restart your router by unplugging it for 30 seconds.

Can I cast to multiple Chromecast devices at the same time?

No. One phone can only cast to one Chromecast device at a time. If you want to cast to a different device, disconnect from the first one and select the new device from the Cast menu.
