The three ways to connect your phone to your TV
You can connect your phone to your TV using a cable, a wireless connection, or by casting video from apps. The method that works depends on what TV you have, what phone you have, and what you want to do — watch a photo album, mirror your entire screen, or stream from a single app like Netflix.
Most modern smart TVs support at least two of these methods. If your TV is older or basic, a cable connection is usually your only option. The wireless methods are faster to set up once, but cables are more reliable if you connect the same way every time.
Key Takeaways
- HDMI cables work with any phone that has an HDMI port or an adapter, and they are the most reliable connection for older TVs.
- Wireless casting from apps like Netflix, YouTube, or Apple TV works on most smart TVs without any setup beyond connecting to the same WiFi network.
- Screen mirroring (AirPlay on iPhones, Miracast on Android phones) copies everything on your phone to your TV and works on most TVs made in the last five years.
- If your TV does not have the feature you need, a streaming device like a Roku or Apple TV can add it for under $50.
Using a cable: HDMI adapters for any phone
An HDMI cable plugged directly into your TV is the most straightforward connection. Most phones do not have an HDMI port, so you need an adapter that converts your phone's charging port to HDMI. For iPhones, buy a Lightning to HDMI adapter. For Android phones, buy a USB-C to HDMI adapter (or Micro-USB if your phone is older). These adapters cost $15 to $30 and work with any TV that has an HDMI port.
Plug the adapter into your phone, connect an HDMI cable to the adapter, and plug the other end into any HDMI port on your TV. Switch your TV to that HDMI input using the remote. Your phone's screen will appear on the TV. This method works on every TV made in the last 15 years and does not require WiFi or any setup.
The downside is that you are tethered to a cable, and some adapters do not charge your phone while connected. If you plan to watch for more than an hour, buy an adapter that supports charging, or plug your phone into power separately.
Casting from apps: Netflix, YouTube, and others
Most streaming apps have a built-in cast button that sends video directly from the app to your TV. Open Netflix, YouTube, Disney+, or Spotify on your phone, tap the cast icon (usually a rectangle with a WiFi symbol), and select your TV from the list. The app plays on your TV while your phone becomes a remote control.
This method works on almost every smart TV made in the last five years, and it requires nothing but WiFi. Your phone and TV must be on the same network. You do not need to buy anything or change any settings on your TV — the feature is built in.
Casting only works within the app itself. If you want to show a photo from your phone's camera roll or a web page from your browser, you need screen mirroring instead. But for watching shows and music, casting is the simplest option because the app controls the quality and connection automatically.
Screen mirroring: Copying your entire phone screen
Screen mirroring copies everything on your phone — apps, web pages, photos, text messages — to your TV in real time. On iPhones, it is called AirPlay. On Android phones, it is called Miracast or Smart View depending on the brand. Both work the same way: swipe down from the top of your phone to open the quick settings, tap the screen mirroring or AirPlay button, and select your TV.
Your TV must support the same standard as your phone. Most smart TVs made since 2018 support both AirPlay and Miracast, but older TVs may support only one or neither. Check your TV's manual or settings to see which it supports. If your TV does not support either, a streaming device like an Apple TV, Roku, or Fire Stick can add the feature for $30 to $50.
Screen mirroring is slower to start than casting — it can take 5 to 10 seconds to connect — and it drains your phone's battery faster because it is constantly sending video. But it is the only way to show anything on your phone on your TV, including apps that do not have a cast button.
Connecting to WiFi and troubleshooting common problems
All wireless methods require your phone and TV to be on the same WiFi network. Check that both devices are connected to the same network name in their WiFi settings. If you have a 2.4 GHz and 5 GHz network with the same name, some older phones and TVs work better on 2.4 GHz — try switching if the connection is unstable.
If casting or mirroring does not appear as an option, restart both your phone and TV. Unplug the TV for 10 seconds, then plug it back in. Restart your phone by turning it off and on. Then try again. If it still does not work, check that your TV's software is up to date by going to Settings on the TV remote and looking for a Software Update or System Update option.
If the connection keeps dropping, move your phone and TV closer to your WiFi router, or switch to a wired connection using an HDMI cable. Walls, microwaves, and other wireless devices can interfere with the signal. A cable is always more stable than WiFi if you are having trouble.
When to use each method
| Method | Best for | Requires | Setup time |
|---|---|---|---|
| HDMI cable | Older TVs, reliable connection, any content | Adapter ($15–$30), HDMI cable | 30 seconds |
| App casting | Streaming apps like Netflix, YouTube, Spotify | WiFi, smart TV | 5 seconds |
| Screen mirroring | Photos, web pages, any app, full control | WiFi, TV made after 2018 | 5–10 seconds |
Use a cable if your TV is older than 2018 or if you want the most reliable connection. Use app casting if you only watch streaming services — it is the fastest and easiest. Use screen mirroring if you need to show anything else, like photos or a web page, or if you want full control of what appears on the TV.
Adding features to an older TV
If your TV does not support casting or mirroring, a streaming device can add both features. An Apple TV, Roku, Fire Stick, or Google Chromecast plugs into an HDMI port on your TV and connects to your WiFi. Once set up, you can cast from your phone or mirror your screen to the device instead of the TV itself.
These devices cost $30 to $100 depending on the brand and features. They also add access to streaming apps that your TV might not have built in. If you have an older TV and want wireless options, a streaming device is cheaper than replacing the TV.
Frequently Asked Questions
Do I need to pair my phone with my TV before I can connect?
No. Casting and mirroring work as long as both devices are on the same WiFi network. You do not need to pair them in Bluetooth or any other way. Just open the cast menu on your phone and select your TV from the list.
Can I use my phone as a remote after I connect?
Yes, but only with casting. When you cast an app like Netflix, your phone becomes the remote and the TV shows the app. With screen mirroring, your phone controls what appears on the TV, but the TV remote still works too. With a cable, your phone is just a display — use the TV remote to control volume and input.
Will connecting my phone drain its battery?
Screen mirroring drains the battery faster than normal because it constantly sends video to the TV. Casting uses less power because the TV does most of the work. A cable connection does not drain the battery any faster than normal, and some adapters support charging while connected.
What if my phone and TV are on different WiFi networks?
Casting and mirroring will not work. You must connect both to the same network. If you have a guest network, make sure both devices are on the main network, not the guest one. A cable connection works regardless of WiFi.
Can I connect an Android phone to an Apple TV?
You can cast from Android apps to an Apple TV, but you cannot use Miracast screen mirroring. Use app casting instead, or connect with an HDMI cable and adapter. Newer Apple TVs support some Android casting, but it is not may provide — check the Apple TV manual for your model.
