If you own a smartphone you probably already know you can stream music through YouTube, Spotify, Apple Music, and more. You can also download music straight to your smartphone to keep the data usage down too. When it comes to watching movies on your smartphone, you need to be aware of how much data is used when streaming or downloading movies. Most cell packages will have a data usage limit that gets refreshed each and every month you pay for it. If you decide to download or stream a movie, you’re going to use a lot of your monthly data in doing so.
Most movies will eat a good chunk of your gigabytes every time you watch them online or download them to your smartphone. In this guide, we’ll discuss how much data is used when watching a movie on your smartphone from some of the most popular services so you can make smarter choices.
How many GB is a movie download?
Downloading movies will use a different amount of data depending on the quality you select. For example, if you download a movie in 4K, you’ll use more data than if you downloaded the same movie in SD (standard definition.) We’ll take a look at the different service providers and how much GB it will cost to download movies from them.
We usually recommend downloading your movies instead of streaming them because if you download them once, you can watch them over and over again without using any further precious data.
Netflix

Netflix is one of, if not the most popular streaming services out there. Netflix boasts thousands of movies and TV shows on demand for a reasonable monthly price. You can watch Netflix on your TV, computer, and your smartphone through Netflix’s official app. This is handy if you’re on the go and want to finish an episode of your favorite show on your lunch break, for example.

Disney Plus uses slightly less data than Netflix but it will still eat your data if you download a lot of episodes or multiple movies.

The Bottom Line
Downloading a movie and onto your phone is going to take up a lot of data, especially if you have a monthly data limit. Where you can you should download movies by using your WI-FI connection first but if you can’t, make sure you keep an eye on your current data limit so you don’t end up downloading too much and running out quickly. Before you download a movie, make sure you come back and check this page to see if you have enough GB left.
