Change Your Settings to Save Data
Unless you’re fortunate enough to have an unlimited plan, you probably don’t want to burn through all your data at the beginning of each month. Thankfully, there are a couple of ways to preserve your data and still watch movies and shows on your iPhone.
All you need to do to save data is lower your resolution settings. That, of course, means that you’ll need to watch your favorite content at slightly lower quality, but it’s a great way to never miss an episode of your favorite show and you probably won’t notice much difference on the smaller screen anyway.
How you change this setting will depend on which streaming services you use. For instance, with Netflix and Disney+ you’ll need to open the specific app and go into its settings, where you should find an option for Cellular Data Usage.
For Apple’s TV app, you can change the settings by going to Settings > Apple TV and enabling Use Cellular Data. Afterward, tap Cellular and select Automatic.
