Smart Downloads only work for episodic TV shows and will not automatically replace a movie with another similar program. If a movie you download is 1GB in size, it will take 80 seconds to download at this speed. Therefore, if your connection speed is 100Mbps, you can download 12.5MB of data per second.
Mbps: Speed is measured in Megabits per second. If users want to keep an episode downloaded to their device without having to worry about Smart Downloads deleting it, the feature can be turned off as well. So if you download a 500MB file, you are using 0.5GB of your monthly data allowance. Once you connect to your office WiFi, Netflix will delete the episodes you've already watched and seamlessly download the next one in the background. How is this useful? Imagine you download an episode or two of Stranger Things at home and watch it on the subway ride to work. "And you have to manually go back and delete episodes." "Downloading is a very manual process today," Netflix director of product innovation Cameron Johnson told BuzzFeed News. Netflix explains that Smart Downloads are only activated when users are connected to Wi-Fi and are done with an episode. The company says this will help to save space on smartphones and tablets while ensuring that users can keep binges going without having to search through the app's menus for the next episode they want to watch offline. Netflix has announced a new feature launching for Android smartphones and tablets today, and coming to iOS devices later this year, called "Smart Downloads." With this turned on, the Netflix app will automatically delete the downloaded episode of a show that you've finished watching offline, and replace it by automatically downloading the next episode in line (via BuzzFeed News).
