The three ways to connect your phone to a TV
You can connect your phone to a TV using a cable, a wireless connection, or a casting device. The fastest and most reliable method is a cable — either HDMI (for Android phones with the right adapter) or USB-C to HDMI. If you want to avoid cables, most newer TVs support wireless casting through Miracast (Android), AirPlay (iPhone), or Chromecast (any phone with the Google Home app). A third option is a streaming device like a Roku, Fire Stick, or Apple TV, which connects to your TV once and then receives video from your phone over WiFi.
Which method works best depends on what phone you have, what TV you own, and whether you want a permanent setup or something you use occasionally. A cable is best if you need zero lag for gaming or presentations. Wireless casting is best if you want to move around the room. A streaming device is best if multiple people in your household will cast to the TV regularly.
Key Takeaways
- HDMI cables with the right adapter are the fastest and most reliable way to connect, with no lag and no WiFi needed.
- Wireless casting (AirPlay for iPhone, Miracast or Google Cast for Android) works on most modern TVs without extra hardware, but requires a strong WiFi connection.
- Streaming devices like Chromecast, Roku, and Fire Stick plug into your TV once and let any phone on your WiFi cast to them.
- Check your phone's port type (USB-C, Lightning, or micro-USB) and your TV's inputs before buying an adapter or cable.
Connecting with a cable (wired)
A wired connection is the most direct method and has no delay. For Android phones, you need a USB-C to HDMI adapter (or micro-USB to HDMI if your phone is older). 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 and your phone screen appears when ready.
For iPhones, you need a Lightning to HDMI adapter or a Lightning to USB-C adapter paired with a USB-C to HDMI cable. The process is the same: plug the adapter into your phone, connect the HDMI cable, and switch your TV input. The phone will ask permission the first time — tap "Trust" and you are done.
Wired connections work even if your WiFi is down or slow, and they charge your phone while you use it if you buy an adapter with a charging port. The downside is that you are tethered to the TV by a cable, and you cannot use your phone's screen while it is mirroring — the TV shows everything your phone does.
Wireless casting from your phone
Most modern TVs have wireless casting built in. If your TV was made in the last five years, it likely supports at least one casting standard. Check your TV's settings menu or the manual to see which one: Miracast (Android and Windows), AirPlay (iPhone and Mac), or Google Cast (any device with the Google Home app).
To cast from an Android phone, open the Control Center (swipe down from the top twice), look for "Cast" or "Screen Cast", tap it, and select your TV from the list. Your phone screen appears on the TV within a few seconds. To cast from an iPhone, open Control Center, tap "Screen Mirroring", and select your TV. Both methods require your phone and TV to be on the same WiFi network.
Wireless casting lets you use your phone normally while the TV shows what you want — you can open apps, adjust volume, or switch what is playing without the TV following every tap. The tradeoff is that casting depends on WiFi strength; a weak connection can cause stuttering or disconnects. Casting also adds a small delay (usually under a second), which is fine for video or photos but noticeable if you are gaming.
Using a streaming device
A streaming device is a small box that plugs into your TV's HDMI port and connects to your WiFi. Popular options include Google Chromecast, Amazon Fire Stick, Roku, and Apple TV. Once plugged in and set up, any phone on your WiFi can cast to it without needing the TV to support casting natively.
Streaming devices are useful if your TV is older and does not have built-in casting, or if you want a single device that works with iPhones, Android phones, and computers. They also often include their own apps for Netflix, YouTube, and other services, so you can use the device independently of your phone. Setup takes about 10 minutes: plug it in, connect it to WiFi using the device's remote or the manufacturer's app, and you are ready to cast.
The main cost is the device itself (typically $25 to $100 depending on the model). After that, casting is free and works the same way as casting to a TV with built-in support. If you already own one of these devices for streaming, you do not need to buy anything else to connect your phone.
What to check before you buy an adapter or cable
Before purchasing a cable or adapter, identify your phone's port. iPhones use Lightning (older models) or USB-C (iPhone 15 and newer). Android phones use USB-C (most recent models) or micro-USB (older phones). Look at the bottom of your phone or check the manual if you are unsure.
Next, check what inputs your TV has. Look at the back or side of the TV for HDMI ports — most TVs have at least two, and they are labeled HDMI 1, HDMI 2, and so on. If your TV is very old (pre-2010), it may only have composite or component inputs, in which case you would need a more specialized adapter.
Finally, decide whether you need charging while connected. Some USB-C to HDMI adapters include a USB-C charging port, so your phone charges while mirroring. This is useful if you plan to leave your phone connected for long periods. Standard adapters without charging are cheaper and smaller.
Troubleshooting common connection problems
If your phone does not appear when you cast, first check that both devices are on the same WiFi network. Open your phone's WiFi settings and your TV's network settings and confirm they show the same network name. If they do not, connect your phone to the TV's network and try again.
If the picture is choppy or keeps disconnecting, move your phone closer to the TV or router. Walls, microwaves, and other electronics can weaken WiFi. If the problem persists, restart both your phone and TV — turn them off completely, wait 10 seconds, and turn them back on.
For wired connections, if nothing appears on the TV, try a different HDMI port on the TV or a different HDMI cable. Some cables are damaged or do not support video. If you are using an adapter, make sure it is fully inserted into your phone's port and that the HDMI cable is fully inserted into the adapter.
If your TV does not recognize your phone at all, check whether your TV actually supports the casting standard your phone uses. An older TV may support Miracast but not AirPlay, for example. In that case, a streaming device is your best option.

Frequently Asked Questions
Can I charge my phone while it is connected to the TV?
Yes, but only with certain adapters. USB-C to HDMI adapters with a built-in USB-C port allow you to charge while mirroring. For Lightning adapters on iPhones, you would need a separate charging cable. With a streaming device, your phone is not physically connected, so you can charge it separately while casting.
Does casting drain my phone's battery faster?
Yes, casting uses more battery than normal use because your phone is sending video over WiFi and keeping the screen on. A wired connection also drains battery, though some adapters include charging ports to offset this. If you plan to cast for more than an hour, plug your phone in or use an adapter with charging.
What if my TV does not have HDMI ports?
Older TVs with only composite (red, white, yellow) or component (red, green, blue) inputs need a specialized adapter. These are harder to find and less reliable than HDMI. A streaming device is usually the better choice for very old TVs, since it only needs one HDMI port or can work with composite inputs on some models.
Can I cast from my phone to multiple TVs at the same time?
Most phones can only cast to one device at a time. If you want to show the same content on multiple TVs, you would need to cast to each one separately, or use a streaming service that supports multi-room playback (like Spotify or YouTube Music).
Is wireless casting find, or can anyone on my WiFi see what I am casting?
Casting is encrypted, so other people on your WiFi cannot see the content. However, if someone is on your WiFi network, they can cast to your TV themselves unless you password-protect the casting feature in your TV's settings. Check your TV's manual for how to enable casting restrictions.
