I haven't tried this yet, only watched a few YouTube clips.
But I have an iPad Pro 10.5" and a MacBook. Perhaps film viewing is part of your commute.
On my iPhone XS Max i only watch not more than 5 minutes. Because 16:9 is much smaller as the Max will have black bars on side in witch irr1tates me. Also most of the movies i have watch has subtitles! But i cant seem to read subtitles on XS max with fullscreen because it is zoomed! So it is back to being small again just as small as 8 plus at 5.5"
Most of the time i watch extended movies for 7 hour on iPad Mini 4 or iPad Pro 10.5" or macbook and i liked it 10 times than xs max.
I really, really, really, really, really, really like it because iPads and Macbook dont strain my eyes when watching or reading unlike on tiny iPhone XS Max witch is only good for texting and social media
