Yeah, with them touting watching movies and only having "up to 2 hours" of battery, that's going to severely limit the movies you can watch. "Everything, Everywhere, All At Once", which they showed someone watching, is 2.2hrs.
remember he said all day use. not sure what it mean.
All day use if it's plugged in, as in using an AC adapter.
iirc, he said something like "when plugged in you can use it all day, and on battery you get two hours"
