Change Playback Quality on TV App for iPhone

This guide shows you how to adjust the video playback quality in the Apple TV app on your iPhone. Changing this setting lets you control how much cellular data or Wi-Fi bandwidth the app uses when streaming movies and shows, which can help you avoid data overages or improve playback on slower connections. No special tools are needed—just your iPhone with the TV app installed and an active internet connection.

What You’ll Need

• An iPhone running a recent version of iOS (iOS 12 or later is fine for most steps).
• The TV app (it comes pre-installed on iPhones).
• An active internet connection (Wi-Fi or cellular) to stream content.
• Your Apple ID signed in if you want to stream purchased or rented content.

Step-by-Step

1. Open the Settings app on your iPhone. It’s the gray gear icon on your home screen.
2. Scroll down and tap “TV� in the list of apps. This opens the TV app’s settings menu.
3. Look for the “Playback� section near the top of the screen. You’ll see two options: “Cellular Data� and “Wi-Fi.�
4. Tap “Cellular Data� to change quality when you’re not on Wi-Fi. You’ll see three choices:
   • Good – Uses the least data, roughly 1 GB per hour. Best for limited data plans.
   • Better – Balances quality and data use, about 2 GB per hour.
   • Best – Highest quality, uses about 4 GB per hour. Only pick this if you have unlimited data.
5. Tap your preferred option to select it. A checkmark appears next to your choice.
6. Tap “Wi-Fi� to adjust quality when connected to a Wi-Fi network. The same three options appear: Good, Better, and Best.
7. Select your Wi-Fi quality preference the same way. If you have a fast home connection, “Best� gives you the sharpest picture. On slower public Wi-Fi, “Good� or “Better� may prevent buffering.
8. Exit Settings by swiping down from the top-left corner or pressing the Home button. Your changes save automatically.

That’s it. The next time you stream a movie or show in the TV app, it will use the quality you selected for that connection type.

Common Mistakes

• Changing the wrong setting: Many people adjust the quality inside the TV app itself during playback, but that only affects the current video. The persistent setting lives in the iPhone’s Settings app, not the TV app.
• Forgetting which connection type you’re on: If you set “Cellular Dataâ€� to Good but you’re actually on Wi-Fi, you’ll still get high-quality streams. Always check whether you’re on Wi-Fi or cellular before troubleshooting.
• Assuming “Bestâ€� is always better: On a slow connection, “Bestâ€� can cause constant buffering and a worse experience than “Good.â€� The quality setting is about matching your connection speed, not just maximizing resolution.
• Not restarting the app: If you change settings while a video is already playing, the change may not apply until you start a new stream or restart the app.

Tips

• Use “Goodâ€� on cellular if you have a data cap. At about 1 GB per hour, you can watch roughly 10 hours of video on a 10 GB plan without worrying about overages.
• Choose “Betterâ€� as a middle ground. It’s a good default for most people—decent picture quality without eating through data too fast.
• Switch to “Bestâ€� on unlimited Wi-Fi. If you’re at home with a solid fiber or cable connection, you’ll get the full HD or 4K quality that the content supports.
• Check your iPhone’s overall data usage in Settings > Cellular to see how much the TV app has used after a few days. This helps you decide if you need to lower the quality.
• Remember that this setting also affects downloads. The same quality options apply when you download movies or shows for offline viewing, so pick a lower quality to save storage space.

Troubleshooting

If you’ve changed the settings but don’t see a difference, try these steps in order:

1. Force-quit the TV app. Swipe up from the bottom of the screen (or double-click the Home button on older iPhones) to open the app switcher, then swipe the TV app card away. Reopen the app and start a new video.
2. Check your actual connection speed. Run a speed test (like the one at speedtest.net in Safari). If your download speed is below 5 Mbps, even “Good� may buffer. In that case, the issue isn’t the setting—it’s your network.
3. Restart your iPhone. Sometimes a simple reboot clears stuck network settings. Press and hold the side button and either volume button, then slide to power off. Wait 30 seconds and turn it back on.
4. Toggle the setting off and on. Go back to Settings > TV, switch “Cellular Data� to a different option, then back to your preferred one. This forces the app to re-read the setting.
5. Update iOS. Go to Settings > General > Software Update. If an update is available, install it. Older iOS versions may have bugs that affect video quality settings.
6. Reset network settings (last resort). Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This clears saved Wi-Fi passwords and Bluetooth pairings, so only do this if nothing else works.

Frequently Asked Questions

Does this setting affect Apple TV+ original shows?

Yes. The TV app settings apply to all content streamed through the app, including Apple TV+ originals, purchased movies, and rentals.

Will changing quality affect how much storage downloads use?

Yes. A movie downloaded at “Good� quality takes up roughly half the space of the same movie at “Best.� If you’re low on storage, choose a lower quality for downloads.

Can I set different quality for downloads vs. streaming?

No. The same “Cellular Data� and “Wi-Fi� settings control both streaming and downloads. There’s no separate option for each.

Why don’t I see the TV app in Settings?

The TV app is pre-installed on iPhones, but if you’ve deleted it, it won’t appear in Settings. Re-download it from the App Store, then the Settings section will reappear.

Does this setting affect AirPlay or screen mirroring?

No. AirPlay and screen mirroring use your device’s video output settings, not the TV app’s playback quality. The quality you set here only affects video played inside the TV app itself.

What if I want the highest quality possible regardless of data use?

Select “Best� for both Wi-Fi and Cellular Data. Keep in mind that “Best� on cellular can use 4 GB per hour, which may exceed your plan’s limit quickly.
