YouTube has had resolution settings and ways to keep the app from downloading / streaming HD videos for a while, but this automates the data-saving process and reframes it in a way that’s easier to understand. And any resolution adjustments can be set for the specific video you’re watching or system-wide for everything you watch, with specific behaviors for Wi-Fi and mobile networks. While these umbrella modes are good for quick scenario-specific adjustments to resolution, you can still dig in and get granular with specific resolutions. YouTube’s new video settings include options for “higher picture quality” and “data saver.” YouTube’s new additions are the “higher picture quality” mode, which uses more data when not on Wi-Fi and defaults to 720p, and a “data saver” mode that maxes out at 480p.
You might already be familiar with “auto” mode as the default setting for most videos, which automatically adjusts video resolution depending on your current internet speed to give the best experience. Along with specific resolutions in the video player, you can now toggle between three separate modes that either favor video quality, data use, or whatever works best for your current internet connection. The YouTube mobile app for iOS and Android now has new video settings that might make it a bit easier to save on data while watching video on the go ( via MacRumors).
