The fastest way to stream from iPhone to Samsung TV
The easiest method is AirPlay, which works if your Samsung TV was made in 2018 or later and has AirPlay 2 built in. Open Control Center on your iPhone (swipe down from the top right), tap Screen Mirroring, select your Samsung TV from the list, and your iPhone screen appears on the TV within seconds. No apps to read, no pairing codes to enter.
If your Samsung TV is older or doesn't have AirPlay, you have two other reliable options: SmartThings (Samsung's own app) or Miracast (a wireless standard that works across brands). Both require a few more steps than AirPlay, but they work consistently once set up.
The method you choose depends on your TV's age and which features matter to you — some let you mirror your whole screen, others stream video only. The differences are small, but knowing them upfront saves frustration.
Key Takeaways
- AirPlay 2 is the simplest option if your Samsung TV was made in 2018 or later; it requires no setup beyond opening Control Center on your iPhone.
- SmartThings, Samsung's official app, works on most Samsung TVs from 2016 onward and lets you control what appears on screen without mirroring your entire iPhone.
- Miracast is a wireless standard that works on many Samsung TVs and does not require a Samsung account, though it is less common on newer models.
- Screen mirroring drains your iPhone battery faster than normal use; keep your phone plugged in during long viewing sessions.
Using AirPlay 2 on Samsung TVs made in 2018 or later
AirPlay 2 is built into Samsung TVs from 2018 onward. To check your TV's year, look at the model number on the back or in Settings > Support > About This TV. If your TV is 2018 or newer, AirPlay is already enabled and ready to use.
On your iPhone, swipe down from the top right corner to open Control Center. Tap Screen Mirroring (it looks like a rectangle with a triangle at the bottom). Wait a moment for your iPhone to scan for nearby devices, then tap your Samsung TV's name. Your iPhone screen will appear on the TV in a few seconds. To stop mirroring, open Control Center again, tap Screen Mirroring, and select Stop Mirroring.
AirPlay works best when your iPhone and TV are on the same Wi-Fi network. If they are on different networks (for example, a guest network), AirPlay may not find your TV. Switch your iPhone to the same network as your TV and try again.
Using SmartThings to stream without mirroring your whole screen
SmartThings is Samsung's official app and works on most Samsung TVs made since 2016. Unlike screen mirroring, SmartThings lets you send video or photos to your TV without showing everything on your iPhone screen — your phone can stay locked while the TV plays content. This is useful if you want to watch a video while checking messages or using another app.
read the SmartThings app from the App Store and sign in with a Samsung account (create one free if you don't have one). Open the app, tap Add Device, and select your TV from the list. Your TV will display a PIN; enter it in the app to pair them. Once paired, open a video app like YouTube or Apple TV, tap the AirPlay icon (or the app's cast button), and select your Samsung TV.
SmartThings also works for photos and documents. Open the Photos app, select an image, tap Share, choose SmartThings, and pick your TV. The image appears on screen without mirroring your iPhone.
Miracast: a wireless standard that works across brands
Miracast is a wireless standard supported by many Samsung TVs, though it is less common on newer models (Samsung has shifted toward AirPlay and SmartThings). If your TV supports Miracast, you can mirror your iPhone without a Samsung account or special setup.
To use Miracast, open Control Center on your iPhone, tap Screen Mirroring, and look for your TV's name. If it appears, tap it and enter any PIN your TV displays. Your screen will mirror to the TV. Miracast works the same way as AirPlay once connected — your entire iPhone screen appears on the TV, and battery drains faster than normal.
Miracast support varies by TV model and year. If you don't see your TV in the Screen Mirroring list, it likely does not support Miracast. Check your TV's manual or Samsung's support site for your specific model number.
Troubleshooting when your iPhone won't connect
If your iPhone doesn't find your TV, the most common cause is that they are on different Wi-Fi networks. Check that both devices are connected to the same network — look at Settings > Wi-Fi on your iPhone and compare it to the network name shown on your TV's network settings. If they don't match, connect your iPhone to the TV's network and try again.
Restart both devices if the connection fails after you've confirmed they're on the same network. Unplug your TV for 30 seconds, then plug it back in. On your iPhone, go to Settings > General > Shut Down, wait a few seconds, then turn it back on. Try connecting again.
If your TV is very old (before 2016), it may not support any wireless streaming from iPhone. In that case, you can use an HDMI adapter to connect your iPhone directly to the TV with a cable, though this limits you to video and photos, not full screen mirroring.
Why your battery drains faster during streaming
Screen mirroring uses your iPhone's Wi-Fi radio and processor continuously, which drains the battery much faster than normal use — expect to lose 10 to 15 percent per hour depending on your iPhone model and screen brightness. If you plan to stream for more than an hour, plug your iPhone into power.
Lowering your iPhone's screen brightness also helps, since the display itself uses significant power. You can also close other apps running in the background to reduce processor load, though the effect is smaller than plugging in.
When to use a cable instead of wireless streaming
If your TV is older than 2016 or doesn't support AirPlay, SmartThings, or Miracast, a wired connection is your only option. Buy a Lightning to HDMI adapter (Apple's official version costs around $50, and third-party versions are cheaper). Plug the adapter into your iPhone's charging port, connect an HDMI cable from the adapter to your TV, and your iPhone screen appears on the TV.
Wired connections are also more stable if you have Wi-Fi interference in your home — they don't depend on wireless signal strength. The trade-off is that your iPhone stays tethered to the TV with a cable, and you can't use the charging port while streaming.
Frequently Asked Questions
Do I need a Samsung account to stream from my iPhone?
No, not for AirPlay or Miracast. Both work without an account. SmartThings requires a free Samsung account, but you only create it once during setup. After that, streaming works automatically when your TV and iPhone are on the same network.
Can I stream to my Samsung TV if it's on a different Wi-Fi network than my iPhone?
No. AirPlay, SmartThings, and Miracast all require both devices to be on the same Wi-Fi network. If your TV is on a guest network and your iPhone is on the main network, switch your iPhone to the guest network and try again. Some routers let you connect both networks to the same device; check your router's settings if you want to avoid switching.
What if my Samsung TV is older than 2018?
Older Samsung TVs may not have AirPlay 2. Try SmartThings first — it works on most TVs from 2016 onward. If that doesn't work, check your TV's manual for Miracast support. If your TV supports neither, a Lightning to HDMI adapter is your only wireless-free option.
Does streaming from iPhone to Samsung TV work over cellular data?
No. Streaming requires both devices to be on the same Wi-Fi network. Cellular data on your iPhone won't work. Make sure your iPhone is connected to Wi-Fi before you try to stream.
Can I use my iPhone while streaming to the TV?
With AirPlay and Miracast, your entire screen is mirrored, so anything you do on your iPhone appears on the TV. With SmartThings, you can send video or photos without mirroring your whole screen, so your iPhone stays private. Choose SmartThings if you want to use your phone while the TV plays content.
