I get between 8 hours (lots of touch usage, photo editing, text editing, Office 365, keyboard lights on, higher screen brightness, performance set higher, etc.) to 16 hours (watching video, listening to audio, UWP apps (most), battery saver mode with keyboard lights off, screen lower brightness, performance set low, etc.). Some apps are real power suckers (like Facebook app). Others barely a trickle. Also, setting which apps can use the NVidia GPU is also important......
