The fastest way: use AirPlay if your TV supports it
If your TV is made in the last five years and has AirPlay built in, connecting your iPhone takes about 30 seconds. Open Control Center on your iPhone (swipe down from the top right), tap Screen Mirroring, select your TV from the list, and you're done. Your iPhone screen appears on the TV instantly.
Not all TVs have AirPlay. Samsung, LG, Sony, and most other brands now include it, but older models and budget TVs often don't. If you don't see your TV's name in the Screen Mirroring list, skip to the next section — you'll need a different method.
AirPlay works wirelessly and doesn't drain your iPhone battery faster than normal use. The connection stays live as long as both devices are on the same Wi-Fi network, so you can walk around your house and the signal follows you.
Key Takeaways
- AirPlay is the simplest method if your TV supports it — just open Control Center, tap Screen Mirroring, and select your TV.
- If your TV doesn't have AirPlay, an Apple TV 4K or a third-party adapter like a Roku or Fire Stick will add the feature for under $50.
- HDMI adapters let you plug your iPhone directly into your TV, but they only work with video apps and don't mirror your whole screen.
- Make sure your iPhone and TV are on the same Wi-Fi network before you try to connect — this is the most common reason the connection fails.
- Casting video from apps like YouTube or Netflix works differently than screen mirroring and doesn't require AirPlay.
Using an Apple TV or streaming device if your TV doesn't have AirPlay
An Apple TV 4K plugs into your TV's HDMI port and adds AirPlay to any television. Once it's set up, your iPhone connects the same way as if AirPlay were built in. Apple TV 4K costs around $129, but it also gives you access to Apple's streaming apps and lets you use Siri voice commands on your TV.
If you already own a Roku, Amazon Fire Stick, or Google Chromecast, those devices also support AirPlay on newer models. Check your device's settings to turn on AirPlay if it's not already on. This is the cheapest option if you're buying something new — a basic Fire Stick costs around $40 and does the same job as Apple TV for screen mirroring.
All of these devices need to be plugged into power and connected to your Wi-Fi network. Once they're set up, they stay ready to receive your iPhone's signal without any extra steps each time you want to connect.
Plugging in directly with a USB-C or Lightning to HDMI adapter
A USB-C to HDMI adapter (or Lightning to HDMI on older iPhones) lets you plug your iPhone straight into your TV's HDMI port with a cable. This method works instantly with no setup, and the connection is rock-solid because it's physical. You can buy these adapters for $15 to $30 online or at electronics stores.
The catch is that direct HDMI only works with certain apps. Video apps like Netflix, YouTube, and Apple TV+ will display on your TV, but you can't mirror your whole iPhone screen the way you can with AirPlay. If you want to show someone photos, browse the web, or use your phone's home screen on the big display, this method won't work.
Your iPhone will charge while plugged in, which is useful for longer viewing sessions. The adapter itself is small and portable, so you can carry it to someone else's house if you need to connect there.
Casting from video apps without mirroring your whole screen
Netflix, YouTube, Disney+, and most other streaming apps have their own cast button built in. Look for a rectangle with a Wi-Fi symbol in the corner — it's usually in the top right or bottom right of the app. Tap it, select your TV, and the video plays on the big screen while your iPhone goes back to normal use.
This method doesn't require AirPlay or any extra hardware. It works on any TV as long as you have a streaming device plugged in or AirPlay built in. The app handles the connection directly, so your iPhone doesn't have to stay in the same room or stay awake.
Casting is different from screen mirroring — you're sending just the video to your TV, not your entire phone display. This means you can use your iPhone for other things while the show plays, and the video quality is often better because the app sends a direct stream instead of mirroring your screen.
Troubleshooting when your iPhone won't connect
The most common reason connection fails is that your iPhone and TV are on different Wi-Fi networks. Check that both devices are connected to the same network — look at your Wi-Fi settings on your iPhone and compare it to the network name shown on your TV or streaming device. If they don't match, connect your iPhone to the same network and try again.
If your TV or streaming device isn't showing up in the Screen Mirroring list at all, restart both devices. Turn off your TV and streaming device completely, wait 10 seconds, and turn them back on. Then try Screen Mirroring again. This fixes most connection problems that aren't related to the Wi-Fi network.
Make sure AirPlay is actually turned on in your TV's settings. Some TVs have it disabled by default, and you have to enable it manually. Check your TV's menu — look for AirPlay, Screen Mirroring, or Apple settings depending on the brand. If you're using a streaming device like Roku or Fire Stick, go into its settings app and confirm AirPlay is on.
If you're using a USB-C or Lightning adapter and nothing appears on your TV, try a different HDMI cable. The cable might be damaged even if it looks fine. Also make sure you're plugging the adapter into an HDMI port that's actually connected to your TV's input — some TVs have multiple HDMI ports and you have to select the right one with your remote.

Frequently Asked Questions
Do I need to buy anything if my TV is brand new?
Probably not. Most TVs made since 2019 have AirPlay built in. Check your TV's manual or settings menu for AirPlay or Screen Mirroring. If it's there, you don't need to buy anything — just use Control Center on your iPhone.
Can I connect my iPhone to an old TV from 2010?
Yes, but you'll need either a USB-C to HDMI adapter (for video apps only) or a streaming device like a Fire Stick or Roku plugged into the HDMI port. An Apple TV 4K also works but costs more. The adapter is the cheapest option if you only want to watch Netflix or YouTube.
Will connecting my iPhone to my TV drain the battery?
Wireless AirPlay uses a little extra battery, but not dramatically — expect maybe 10 to 15 percent more drain than normal use. A USB-C to HDMI adapter actually charges your iPhone while you use it, so battery drain isn't a concern. Casting from apps uses very little battery because your phone isn't mirroring the screen.
What if my TV is connected to a different Wi-Fi network than my iPhone?
AirPlay won't work until both devices are on the same network. Check your iPhone's Wi-Fi settings and connect to the same network your TV is using. If you don't know which network your TV is on, check your TV's settings menu or the manual that came with it.
Can I use AirPlay and watch Netflix at the same time on my iPhone?
Not with screen mirroring — if you're mirroring your whole screen, your iPhone shows whatever is on the TV. But if you use Netflix's built-in cast button instead of AirPlay, you can watch on your TV while your iPhone goes back to normal use and you can do other things with it.
