If the test is successful and Netflix users embrace the feature, the company might roll it out to other devices, according to The Verge. For now, the sleep timer is only available on adult profiles.
Plenty of other apps have sleep timers, including audio-focused ones such as Spotify, Pocket Casts and Pandora. If you often nod off while watching Netflix, this could help you avoid waking up without a diminished battery charge on your device. It should be easier to keep your place in a series as well, since episodes won’t keep playing while you sleep.
