The Basic Steps to Cast from iPhone to Chromecast

To cast from your iPhone to a Chromecast device, open the app you want to cast from—YouTube, Netflix, Spotify, or another supported app—and look for the Cast icon, which looks like a rectangle with curved lines in the corner. Tap it, select your Chromecast device from the list, and the content will begin playing on your TV. Your iPhone controls the playback while the video or audio streams directly from the internet to your Chromecast, not through your phone.

The Cast icon appears in different locations depending on the app. In YouTube, it's in the top right corner. In Netflix, swipe up from the bottom or look in the top right. In Spotify, tap the "Now Playing" bar at the bottom, then look for the Cast icon. Not every app supports casting—check the app's menu if you don't see the icon when ready.

Your iPhone and Chromecast must be on the same Wi-Fi network for casting to work. If they're on different networks, the Cast icon won't show your device, or it will appear grayed out. Check your phone's Wi-Fi settings and make sure your Chromecast is connected to the same network as your phone.

Key Takeaways

  • The Cast icon appears in most streaming apps in the top right corner or in the playback controls—tap it to see available Chromecast devices.
  • Your iPhone and Chromecast must be connected to the same Wi-Fi network before casting will work.
  • Once you cast, your iPhone becomes a remote control and the content streams directly to your TV, so you can lock your phone or switch apps without interrupting playback.
  • Not all apps support casting; YouTube, Netflix, Spotify, Disney+, and Hulu are among the most common, but smaller apps may not have the feature.
  • If the Cast icon doesn't appear, restart both your iPhone and Chromecast, then check that they're on the same network.

Making Sure Your Devices Are on the Same Network

Before you can cast, both devices must see each other on the same Wi-Fi network. Open Settings on your iPhone, tap Wi-Fi, and note which network you're connected to. Then check your Chromecast: open the Google Home app on your iPhone, tap the device, go to Settings, and look at the Wi-Fi network listed there. If they don't match, reconnect your Chromecast to your iPhone's network using the Google Home app.

If your home has a 5 GHz and 2.4 GHz network with the same name, your iPhone might be on one and your Chromecast on the other. Some older Chromecast models only support 2.4 GHz. Check the Google Home app to see which band your Chromecast is using, then manually switch your iPhone to match if needed. This is a common reason casting fails silently.

Casting When the Cast Icon Doesn't Appear

If you don't see the Cast icon in an app, the app may not support casting, or your devices may not be on the same network. First, verify both devices are on the same Wi-Fi network by checking Settings on your iPhone and the Google Home app on your Chromecast. If they match, try closing and reopening the app, or restart your iPhone entirely.

Some apps hide the Cast icon until you start playing content. In YouTube, start a video first, then look for the Cast icon. In Netflix, begin playing a show or movie, then swipe up or tap the menu to find it. If the icon still doesn't appear after these steps, the app version you have may not support casting—check the app store to see if an update is available.

If casting worked before but stopped working, restart your Chromecast by unplugging it for 10 seconds, then plugging it back in. While it restarts, also restart your iPhone. Once both devices are back online and on the same network, try casting again.

Controlling Playback and Stopping a Cast Session

Once casting starts, your iPhone becomes a remote. You can pause, play, skip forward or backward, adjust volume, and change videos or songs directly from your phone. The content plays on your TV while your phone controls it. You can lock your iPhone, switch to another app, or even leave the room—playback continues on the TV uninterrupted.

To stop casting, open the app you're casting from and tap the Cast icon again. Select "Stop Casting" or straightforward tap your Chromecast device name to disconnect. The video or audio will stop playing on your TV, and your iPhone will no longer control the Chromecast. You can also stop casting by unplugging the Chromecast or turning it off, though this is less graceful.

Casting Audio vs. Video Content

Casting works the same way for audio and video, but the experience is slightly different. When you cast video from YouTube or Netflix, the picture appears on your TV and your iPhone controls playback. When you cast audio from Spotify or Apple Music, the song plays through your TV speakers (or connected speakers), and your phone shows the album art and playback controls.

Some apps let you cast to multiple devices at once. Spotify, for example, allows you to cast to a Chromecast speaker and control it from your phone while music plays in another room. Check the Cast menu in the app to see if multiple devices are available—if they are, you can select more than one before hitting play.

Troubleshooting Common Casting Problems

If casting starts but then stops or stutters, the problem is usually your Wi-Fi connection. Move your iPhone and Chromecast closer to your router, or check if other devices are using a lot of bandwidth. Streaming video uses more data than audio, so a weak connection affects video casting more noticeably. If your Wi-Fi is slow, restart your router by unplugging it for 30 seconds.

If the Cast icon appears but your Chromecast device doesn't show up in the list, your devices are not on the same network. Double-check the Wi-Fi network name on both your iPhone and in the Google Home app. If they match but the device still doesn't appear, restart both devices and try again. If the problem persists, remove your Chromecast from the Google Home app and set it up again using the app's setup process.

If casting works for some apps but not others, those apps may not support casting or may need an update. Check the app store for updates, and if an update is available, install it and try again. Some older or less common apps straightforward don't have casting built in—in those cases, you may need to use screen mirroring instead, which mirrors your entire iPhone screen to the TV rather than casting the app's content.

When to Use Screen Mirroring Instead of Casting

Casting and screen mirroring are different. Casting sends the app's content directly to your Chromecast from the internet, while screen mirroring copies everything on your iPhone screen to your TV. Casting is more efficient and lets you use your phone for other things, but not all apps support it. Screen mirroring works with any app but uses more battery and can be slower.

If an app doesn't have a Cast icon, you can still get its content on your TV using screen mirroring. Swipe down from the top right of your iPhone to open Control Center, tap Screen Mirroring, and select your Chromecast device. Your entire iPhone screen will appear on the TV. This works for any app, but remember that your phone's screen is being mirrored, so notifications and other activity will show on the TV too.

Frequently Asked Questions

Do I need to keep my iPhone unlocked while casting?

No. Once casting starts, you can lock your iPhone, switch to other apps, or put it in your pocket. The content continues playing on your TV. Your phone is just sending commands to the Chromecast, not streaming the video through itself.

Can I cast from multiple iPhones to the same Chromecast at the same time?

No. Only one device can cast to a Chromecast at a time. If another iPhone tries to cast while one is already casting, it will stop the first cast and start its own. You can take turns, but not simultaneously.

Why does casting work sometimes but not other times?

The most common reason is that your iPhone and Chromecast lost connection to the same Wi-Fi network. Check your Wi-Fi settings and the Google Home app to confirm both are on the same network. Weak Wi-Fi or network interference can also cause casting to fail—try moving closer to your router or restarting it.

Can I cast if my iPhone is on cellular data instead of Wi-Fi?

No. Your iPhone must be on the same Wi-Fi network as your Chromecast. Cellular data doesn't work for casting because the Chromecast can't see your phone on a cellular connection. Switch your iPhone to Wi-Fi first.

What's the difference between casting and AirPlay?

Casting is for Chromecast devices and uses Google's technology. AirPlay is Apple's system for sending content to Apple TV and other AirPlay-compatible devices. They work similarly but are not compatible with each other—use casting for Chromecast and AirPlay for Apple devices.
