Chromecast vs AirPlay: Which Casting Technology Is Better?

Casting is the easiest way to send video from your phone to the TV. The two dominant technologies are Google Cast (often called “Chromecast”, after Google’s original device) and Apple’s AirPlay. They achieve similar things in slightly different ways.

Comparing Chromecast vs AirPlay side by side makes it clear what works with what. For step-by-step instructions, see our guide on how to cast your phone to a TV.

The short answer

• iPhone, iPad and Mac households: AirPlay is the most seamless, especially with an Apple TV.
• Android households: Google Cast is built in and works with a huge range of apps and TVs.
• Mixed households: Google Cast works from apps on both Android and iPhone; many TVs support both technologies.

How they work

Both have two modes:

Mode	What happens
Casting from an app	The TV fetches the video directly from the internet; your phone acts as a remote
Screen mirroring	Your device’s screen is copied to the TV

Google Cast

When you tap the Cast icon in an app, your phone tells the TV which video to play. The TV streams it directly, so quality is high and your phone is free for other things.

AirPlay

AirPlay can work the same way for many apps — the TV streams directly — or send video from your device. It’s built into iOS, iPadOS and macOS, so the AirPlay option appears system-wide.

Side-by-side comparison

	Google Cast	AirPlay
Sending devices	Android, iPhone/iPad (in apps), Chrome browser, some laptops	iPhone, iPad, Mac
Receiving devices	Google TV devices, Chromecast, many smart TVs and speakers	Apple TV, many smart TVs, AirPlay speakers
System-wide button	Android (Quick Settings)	Yes, across Apple devices
Screen mirroring	Android and Chrome tabs/desktop	iPhone, iPad, Mac
App support	Very wide	Very wide on Apple devices
Multi-room audio	Speaker groups	AirPlay 2 multi-room
Works across ecosystems	Yes (in apps on iPhone)	Mostly Apple-only senders

Quality

When casting from an app, the TV streams the video itself, so quality depends on the TV/device, your Wi-Fi and the service — up to 4K HDR if everything supports it. Mirroring quality is usually lower and can lag, because it’s encoding your screen in real time.

Latency

• Casting from an app: latency doesn’t matter much — the TV plays the stream independently.
• Mirroring: there’s a small delay, fine for photos and presentations, less suitable for fast games. For the lowest delay, use a cable — see how to connect a laptop to a TV with HDMI.

TV and device support

Google Cast receivers

• Google TV devices, including the Google TV Streamer.
• Older Chromecast devices.
• Many smart TVs with Cast built in (often Google TV/Android TV models and others).
• Cast-enabled speakers and displays.

AirPlay receivers

• Apple TV.
• Many smart TVs from major brands (check the model).
• AirPlay 2 speakers and some streaming sticks.

Audio and multi-room

• AirPlay 2 lets Apple devices play to several speakers in sync, controlled from Control Centre or the Home app.
• Google Cast supports speaker groups, so music plays across several Cast speakers at once.

Both work well for music around the home; your speaker brand and phone will decide which is easier.

Privacy and control

• Google Cast: anyone on your network can typically see and cast to your TV; many devices offer settings to limit casting by others.
• AirPlay: you can require a code, restrict access to people in the same home, or allow everyone on the network.

On shared or hotel networks, check these settings — and disconnect when you’ve finished.

Troubleshooting both

If the cast or AirPlay option doesn’t appear:

1. Put both devices on the same Wi-Fi network.
2. Restart the app, phone and TV.
3. Turn off VPNs on the phone.
4. Check the router isn’t isolating devices (AP/client isolation).
5. Update the TV or streaming device software.

If casting starts but stutters, improve Wi-Fi at the TV — see how to improve Wi-Fi for streaming.

Casting at a hotel or friend’s house

Casting in someone else’s space comes with quirks:

• Hotel Wi-Fi often isolates devices, so your phone can’t see the TV. Some hotels offer their own casting system — check the room information.
• Captive portals (the sign-in page on hotel Wi-Fi) can stop streaming devices connecting. Bringing a travel router or using a cable may be easier.
• At a friend’s house, join their Wi-Fi and look for the TV in the cast menu. Disconnect when you’re done.
• Sign out of any accounts you used on someone else’s TV.

Common myths

“Casting uses my phone’s battery and data.” Not when casting from a supported app: the TV streams directly over Wi-Fi, and your phone just sends commands.

“Casting reduces quality.” Not for app casting — the TV fetches the stream itself, often at higher quality than the phone would. Screen mirroring is different and usually lower quality.

“You need the same brand of phone and TV.” No. Google Cast works from iPhone apps, and many TVs support both technologies.

“Mirroring works for everything.” Many streaming apps block mirroring of protected content, showing a black screen. Use the app’s cast or AirPlay button instead.

Quick setup checklist

• Phone and TV on the same Wi-Fi network (not guest)
• TV or streaming device supports Cast, AirPlay or both
• App updated on the phone
• VPN off on the phone
• Router not isolating devices
• Use app casting for films; mirroring for photos and presentations

Which should you use?

You have…	Use
iPhone + Apple TV	AirPlay
Android phone + Google TV	Google Cast
iPhone + Google TV	Google Cast from apps
Android + AirPlay-only TV	Use the TV’s own apps or a Cast-enabled stick
A smart TV supporting both	Whichever your phone supports best

The bottom line

AirPlay is the natural choice for Apple households; Google Cast is the natural choice for Android — and works from iPhone apps too. Many TVs support both, so in practice you’ll use whichever button appears on your phone.
