Android/iOS: Netflix started testing a data saver feature last month to help you control the quality of a video stream when you're on a mobile network so you don't eat through your data plan. Now, it's available for everyone. The new setting allows you to pick from a number of options for the video quality of your stream, from low to unlimited. Each transmits a different amount of data per hour. Low eats up around 1GB per four hours of video and high eats up around 1GB for one hour. The "automatic" option is enabled by default, which means Netflix will automatically cut the the quality when you're not on Wi-Fi. So, if you prefer a higher quality stream, you might want to hop into the app's settings and change that toggle now.
