The three ways to connect your iPhone to your TV

You can connect your iPhone to a TV using an HDMI adapter, AirPlay wireless casting, or an HDMI cable with a Lightning connector. Which one works depends on what TV you have, what iPhone model you own, and whether you want a wired or wireless connection. Most people find AirPlay the easiest if their TV supports it, but the adapter method works with almost any TV made in the last ten years.

The connection itself takes less than a minute once you have the right cable or know your TV's name. After that, your iPhone screen mirrors to the TV, or you can send just video and audio from specific apps like Netflix or YouTube while keeping your phone free to use for other things.

Key Takeaways

  • AirPlay works wirelessly if your TV has AirPlay built in or if you own an Apple TV box, and it is the fastest method to set up.
  • An HDMI adapter plugged into your iPhone's charging port works with any TV that has an HDMI input, including older models.
  • Wired connections are more reliable for video that needs to stay smooth, like gaming or watching movies, because they do not depend on your WiFi.
  • Your iPhone and TV must be on the same WiFi network for AirPlay to work, but wired connections need no network at all.

Using AirPlay to cast wirelessly

AirPlay is Apple's wireless casting system. If your TV was made after 2018 and cost more than $300, it probably has AirPlay built in. Newer Samsung, LG, Sony, and Vizio TVs all support it. If you are not sure, check your TV's manual or search the model number plus "AirPlay" online.

To use AirPlay, make sure your iPhone and TV are connected to the same WiFi network. Swipe down from the top-right corner of your iPhone screen to open Control Center. Tap "Screen Mirroring" and wait for your TV to appear in the list. Tap your TV's name, and your iPhone screen will appear on the TV within a few seconds. To stop, open Control Center again, tap "Screen Mirroring", and tap "Stop Mirroring".

If your TV does not have AirPlay built in, you can add it by connecting an Apple TV box to your TV's HDMI port. An Apple TV 4K costs around $130, but older used models work too. Once connected, the Apple TV joins your WiFi network, and AirPlay will then work the same way.

Using an HDMI adapter with a Lightning cable

An HDMI adapter is a small device that plugs into your iPhone's charging port on one end and has an HDMI cable attached or a port for one on the other. These adapters cost $15 to $30 and work with any TV that has an HDMI input. They work with every iPhone model from the iPhone 6 onward.

Plug the adapter into your iPhone's charging port. Plug one end of an HDMI cable into the adapter and the other end into any HDMI port on your TV. Switch your TV to that HDMI input using the remote or the input button on the TV itself. Your iPhone screen will appear on the TV immediately. The adapter does not need WiFi, and the connection is instant and stable.

One limitation: while your phone is connected this way, you cannot charge it at the same time unless you buy a more expensive adapter that has a charging port built in. For watching a movie or showing photos, this is usually fine. For longer use, plug your phone into power first, then connect the adapter.

Using a USB-C to HDMI adapter on newer iPhones

If you own an iPhone 15 or later, your phone uses a USB-C port instead of Lightning. You will need a USB-C to HDMI adapter instead of a Lightning one. These adapters work exactly the same way: plug it into your phone, connect an HDMI cable, and switch your TV to that input. They cost about the same as Lightning adapters, around $15 to $30.

The advantage of USB-C is that many of these adapters also include a USB-C port for charging, so you can charge your phone while it is connected to the TV. Check the product description before buying to confirm it has a charging port if that matters to you.

Sending video from apps instead of mirroring your whole screen

Mirroring shows everything on your iPhone screen on the TV, including notifications and any app you open. If you want to send video from just one app — like Netflix, YouTube, or Apple TV — without mirroring your whole screen, look for a casting icon inside that app.

The casting icon usually looks like a rectangle with curved lines in the corner, or it may say "AirPlay" or "Cast". Tap it, select your TV or Apple TV from the list, and the video will play on your TV while your phone screen goes dark or shows controls. This method uses less battery and lets you use your phone for other things while the video plays.

Not every app has this feature. Streaming apps like Netflix, Disney+, YouTube, and Apple TV+ all have it. Apps that do not stream video usually do not offer it. If you do not see the icon, mirroring your whole screen is your only option.

Troubleshooting when your iPhone will not connect

If AirPlay is not finding your TV, restart both devices. Turn off your iPhone completely, wait ten seconds, and turn it back on. Do the same with your TV. Then check that both are on the same WiFi network — look at your iPhone's WiFi settings and your TV's network settings to confirm they show the same network name.

If you are using an HDMI adapter and nothing appears on the TV, try a different HDMI cable first — cables fail more often than adapters do. If that does not work, try a different HDMI port on your TV. Some ports are faster or more reliable than others. If you still see nothing, the adapter itself may be faulty; try borrowing one from a friend to test.

If your TV is very old and does not have HDMI at all, you cannot use these methods. Older TVs with only composite (red, white, yellow) ports or VGA ports require different adapters that are harder to find and less reliable. In that case, buying an inexpensive streaming device like a Roku or Fire Stick is usually easier than hunting for an old adapter.

Wired versus wireless: which should you use

Wireless (AirPlay) is faster to set up and more convenient for casual use. You do not need cables, and you can move your phone around the room. The trade-off is that it depends on your WiFi. If your WiFi is slow or unstable, the video may stutter or drop.

Wired (HDMI adapter) is more reliable for anything that needs smooth, uninterrupted video — gaming, watching movies, or presentations. It does not depend on WiFi, so there is no lag or buffering. The trade-off is that you need a cable and your phone stays in one place. For most people, wireless is fine for watching shows and browsing. For gaming or professional use, wired is better.

Frequently Asked Questions

Do I need to buy anything if my TV has AirPlay?

No. If your TV has AirPlay built in, you need nothing but your iPhone and WiFi. If your TV does not have AirPlay, you will need an Apple TV box, which costs around $130. If you want to use an HDMI adapter instead, that costs $15 to $30.

Can I charge my iPhone while it is connected to the TV?

With a basic HDMI adapter, no — the adapter uses your charging port. You can buy adapters with a charging port built in for around $40 to $60, or you can charge your phone first and then connect. With USB-C adapters on iPhone 15 and later, many models include a charging port, so check the product details.

What if my TV does not have HDMI?

Very old TVs with only composite or VGA ports cannot use these methods. Your best option is to buy a streaming device like a Roku, Fire Stick, or Apple TV, which connects to your TV and lets you stream content. These cost $30 to $130 depending on the model.

Will connecting my iPhone to the TV drain the battery?

Yes, both wired and wireless connections use more battery than normal. Wired connections use slightly less because your phone does not have to maintain a WiFi connection. For long sessions, plug your phone into power or use an adapter with a charging port built in.

Can I use AirPlay if my TV is on a different WiFi network than my iPhone?

No. Your iPhone and TV must be on the same WiFi network for AirPlay to work. Check your TV's network settings and your iPhone's WiFi settings to confirm they show the same network name. If they do not, connect your TV to the correct network first.
