Though the video streaming company released a new version of the app yesterday (12.44) that included “support for iPhone X,” battery drainage is still being reported by users on Twitter at time of writing.

So for now, it might be a good idea to delete your YouTube app—or at least make sure it’s closed at all times, so you’re not caught with a surprise dead battery.
