iPhone and Chromecast don't connect the way Android phones do
Your iPhone cannot connect directly to Chromecast the way an Android phone can. Apple and Google do not use the same casting technology. Instead, you cast through an app — the app sends the video or audio to your Chromecast device, not your phone's operating system.
This means you need the right app installed on your iPhone, and that app must support Chromecast. Most major streaming services do: YouTube, Netflix, Spotify, Disney+, Hulu, and others all have Chromecast built in. But not every app supports it, so the first step is checking whether the app you want to use has a cast button.
Your Chromecast device must also be on the same Wi-Fi network as your iPhone. If your phone is on a different network — or on a guest network — it will not see your Chromecast.
Key Takeaways
- iPhone casting works through individual apps, not through a system-wide setting, so you need an app that supports Chromecast.
- Your iPhone and Chromecast must be connected to the same Wi-Fi network for casting to work.
- Look for a cast icon (usually a rectangle with curved lines in the corner) in the app's playback controls.
- Once you tap the cast icon and select your Chromecast, the app controls the playback from your phone, but the video plays on your TV.
Check that your app supports Chromecast
Open the app you want to use — YouTube, Netflix, Spotify, or another service. Start playing a video or song. Look at the playback controls for a cast icon: it looks like a small rectangle with curved lines in one corner, usually in the top right or bottom right of the screen.
If you see the cast icon, your app supports Chromecast and you can proceed. If you do not see it, that app does not support casting to Chromecast. You will need to use a different app or a different casting method (like AirPlay to an Apple TV, if you have one).
Some apps hide the cast button until you start playing content, so make sure you have a video or song actually playing before you look for it.
Make sure both devices are on the same Wi-Fi network
Check your iPhone's Wi-Fi settings. Go to Settings > Wi-Fi and note which network you are connected to. Then check your Chromecast: open the Google Home app on any device, tap your Chromecast, go to Settings, and look at the Wi-Fi network listed there.
Both must show the same network name. If your Chromecast is on a different network — or on a guest network while your iPhone is on the main network — they cannot communicate. Switch your iPhone to the same network as your Chromecast, or move your Chromecast to the network your iPhone is using.
If you recently changed your Wi-Fi password, your Chromecast may still be trying to connect with the old one. Unplug the Chromecast for 10 seconds, plug it back in, and wait for it to reconnect.
Tap the cast icon and select your Chromecast device
While playing video or audio in your app, tap the cast icon. A menu will appear showing all Chromecast devices on your network. Select the one you want to cast to — it will usually show the device name you gave it (like "Living Room" or "Bedroom TV").
Once you tap it, the app will connect to your Chromecast. The video or audio will start playing on your TV or speaker, and your iPhone becomes a remote control. You can pause, rewind, adjust volume, or skip tracks from your phone while the content plays on the larger screen.
If your Chromecast does not appear in the list, go back and check that both devices are on the same Wi-Fi network. If they are and it still does not show up, restart your Chromecast by unplugging it for 10 seconds.
Control playback from your iPhone
After you cast, the cast icon will change appearance — it usually fills in or changes color to show that casting is active. Your iPhone screen now acts as a control panel. You can pause and play, skip forward or backward, adjust the volume, and in some apps change subtitles or video quality.
You can also lock your iPhone or switch to a different app while casting continues. The content keeps playing on your TV, and you can return to the casting app at any time to adjust playback.
To stop casting, tap the cast icon again and select Stop Casting. The video or audio will stop playing on your TV, and playback will not resume on your iPhone automatically — you will need to start it again if you want to continue watching.
Troubleshooting: Chromecast does not appear or casting stops
If your Chromecast does not show up in the cast menu, the most common cause is that your iPhone and Chromecast are on different Wi-Fi networks. Check both devices' network settings again. Some routers create separate 2.4 GHz and 5 GHz networks with different names; make sure both your iPhone and Chromecast are on the same one.
If casting starts but stops after a few seconds, your Wi-Fi connection may be dropping. Move your iPhone closer to your router, or move your Chromecast closer to the router. Interference from other devices can also cause this — try turning off nearby Bluetooth devices or moving away from a microwave or cordless phone.
If the app itself crashes or freezes, force-close it completely. On iPhone, swipe up from the bottom of the screen (or swipe down from the top right on newer models) to open the app switcher, find the app, and swipe it up to close it. Then reopen the app and try casting again.
Frequently Asked Questions
Can I cast from Safari or other browsers on my iPhone?
Not directly to Chromecast. Safari does not have built-in Chromecast support. However, many websites have their own apps (YouTube, Netflix, Disney+) that do support casting. If you are trying to cast from a website, open that site's app instead.
What if I want to mirror my entire iPhone screen to Chromecast?
iPhone does not support screen mirroring to Chromecast. You can only cast from apps that have Chromecast built in. If you need to mirror your entire screen, you would need an Apple TV instead, which supports AirPlay mirroring from iPhone.
Do I need to keep my iPhone unlocked while casting?
No. Once casting starts, you can lock your iPhone or switch to other apps. The content continues playing on your TV. You only need to unlock your phone if you want to adjust playback controls in the casting app.
Why does my Chromecast keep disconnecting from my iPhone?
This usually means your Wi-Fi signal is weak or unstable. Move your Chromecast and router closer together, or check whether other devices are using a lot of bandwidth. You can also try restarting your router by unplugging it for 30 seconds.
Can multiple people cast to the same Chromecast at the same time?
No. Only one device can cast to a Chromecast at a time. If someone else tries to cast while you are already casting, their content will take over and yours will stop. You have to stop casting first before someone else can use it.
