The main ways to connect your phone to your TV
You can connect your phone to your TV using a cable, a wireless connection, or a streaming device. The fastest method is usually a cable — either HDMI (if your phone supports it) or USB-C to HDMI. Wireless options like AirPlay, Chromecast, or Miracast work without cables but depend on both devices being on the same Wi-Fi network. Streaming devices like Roku, Apple TV, or Amazon Fire TV add wireless casting to any TV, even older models without built-in support.
Which method works best depends on what phone you have, what TV you own, and whether you want a permanent setup or occasional mirroring. A cable gives you the most reliable connection and charges your phone at the same time. Wireless casting is more convenient for moving between rooms but can lag if your Wi-Fi is slow.
Key Takeaways
- HDMI or USB-C cables are the fastest and most reliable way to connect, and they charge your phone while in use.
- iPhones use AirPlay, Android phones use Chromecast or Miracast, and both require Wi-Fi but work without cables.
- Streaming devices like Roku, Fire TV, or Apple TV add wireless casting to any TV and cost between $30 and $100.
- Cable connections work immediately with no setup; wireless connections need both devices on the same network and take a few seconds to start.
Using a cable to connect directly
A wired connection is the simplest option if your phone and TV both have the right ports. Most newer Android phones have USB-C ports that support video output through a USB-C to HDMI adapter or cable. iPhones with USB-C (iPhone 15 and later) also support this, though older iPhones with Lightning ports do not have video output capability. Check your phone's manual or the manufacturer's website to confirm your model supports video over USB-C.
Plug one end of the HDMI cable into your TV's HDMI port and the other end into the USB-C to HDMI adapter connected to your phone. Your TV should automatically detect the signal and switch to that input. If it does not, use your TV remote to manually select the HDMI input your cable is plugged into. The phone's screen will appear on your TV within seconds, and you can control everything from your phone as normal.
The main advantage of a cable is that it works immediately without any setup, pairing, or network connection. It also charges your phone while you use it. The downside is that you are tethered to the TV and cannot move around the room.
Wireless casting with AirPlay on iPhone
AirPlay is Apple's wireless casting system built into every iPhone, iPad, and Mac. To use it, both your iPhone and TV must be on the same Wi-Fi network. Your TV needs either built-in AirPlay support (common on newer Samsung, LG, and Sony models) or a device that supports it, like an Apple TV, Roku, or Fire TV.
Open Control Center on your iPhone by swiping down from the top-right corner. Tap "Screen Mirroring" and select your TV or AirPlay device from the list. Your iPhone screen will appear on the TV in a few seconds. To stop, open Control Center again and tap "Screen Mirroring," then select "Stop Mirroring."
AirPlay works smoothly for watching videos, browsing, or presentations, though there can be a slight delay of a second or two. If your TV does not show up in the list, make sure both devices are on the same Wi-Fi network and that your TV's AirPlay feature is turned on in its settings.
Wireless casting with Chromecast on Android
Chromecast is Google's wireless casting system available on most Android phones. Like AirPlay, both your phone and TV need to be on the same Wi-Fi network. Your TV needs either built-in Chromecast support (available on many newer models) or a Chromecast device plugged into an HDMI port.
Open the app you want to cast — YouTube, Netflix, Google Photos, or any app with a cast icon. Look for a cast icon (usually a rectangle with a Wi-Fi symbol in the corner) and tap it. Select your TV from the list. The app will start playing on your TV, and you can control it from your phone. To stop, tap the cast icon again and select "Disconnect."
Chromecast works with many streaming apps out of the box, but not all apps support it. If you want to mirror your entire Android screen (not just one app), you can use Google Home: open the app, tap your TV device, then select "Cast my screen." This works on most Android phones but may not be available on all models.
Using a streaming device as a middle ground
If your TV does not have built-in wireless casting, a streaming device adds that capability for $30 to $100. The most common options are Roku, Amazon Fire TV, Google Chromecast with Google TV, and Apple TV. Plug the device into an HDMI port on your TV, connect it to Wi-Fi, and you can cast from your phone immediately.
Roku and Fire TV work with both iPhones and Android phones. Roku uses its own casting system; Fire TV uses Alexa and Chromecast. Google Chromecast with Google TV works best with Android phones but also supports AirPlay from iPhones. Apple TV works best with iPhones but also supports AirPlay from other Apple devices and some Android phones.
Streaming devices are useful if you plan to cast often, want a permanent setup, or have an older TV without wireless features. They also give you access to streaming apps like Netflix, Disney+, and Hulu built into the device itself, so you do not have to cast from your phone every time.
Troubleshooting common connection problems
If your phone does not appear in the casting list, the most common cause is that your phone and TV are on different Wi-Fi networks. Check that both are connected to the same network name. If you have a 2.4 GHz and 5 GHz network with the same name, try connecting both devices to the same band.
If the connection keeps dropping, move your phone closer to the router or TV. Walls, microwaves, and other wireless devices can interfere with the signal. Restart both your phone and TV if the connection is unstable. If you are using a cable and the TV does not recognize it, try a different USB-C to HDMI adapter — some phones work better with certain brands.
For AirPlay, make sure AirPlay is turned on in your TV's settings and that your iPhone is running the latest version of iOS. For Chromecast, check that the Chromecast device has a strong Wi-Fi signal and is up to date. You can check for updates in the Google Home app.

Frequently Asked Questions
Can I connect my phone to a TV that is 10 years old?
Yes, but you will need either a cable (if your phone supports video output) or a streaming device. Older TVs rarely have built-in AirPlay or Chromecast, so a Roku, Fire TV, or Chromecast device plugged into an HDMI port is usually the easiest option.
Does wireless casting work if my Wi-Fi is slow?
Wireless casting can work on slow Wi-Fi, but you may see buffering or lag, especially when streaming video. A wired cable connection is more reliable if your internet is slow. If you use wireless, move closer to your router or reduce the number of devices on your network.
Can I charge my phone while casting wirelessly?
Yes, you can charge your phone with a power cable while casting wirelessly. With a wired HDMI connection, the cable itself may charge your phone depending on the adapter, but check your adapter's specifications first.
What if my phone does not have USB-C?
Older iPhones with Lightning ports do not support video output, so you will need to use AirPlay or a streaming device instead. Older Android phones with micro-USB ports also do not support video output, so wireless casting is your best option.
Do I need to pair my phone and TV every time I cast?
No. Once you cast to a device for the first time, it usually remembers it. The next time you cast, the device should appear in your list immediately. You do not need to pair again unless you reset the TV or streaming device.
