YouTube is reportedly testing two new features for Premium users called Auto Speed and On-the-go. Auto Speed can adjust playback speed automatically to save time, though it is not available on all videos and stays hidden on unsupported content. On-the-go mode is designed for audio-heavy videos and simplifies controls for easier use while moving. It can be enabled manually or triggered after motion is detected. The features are rolling out to more users and are available for testing until April 27.
