It is more leeching than sharing, but if it is actually torrenting then it should also be uploading while the “stream” is playing. So kind of like PeerTube. Just really depends on both how it is setup, and how popular the video is at any time. Though it sucks that there isn’t a good way to make sure connections happen.
There are lots of times that I get torrents the regular way that I would like to have uploading to other peers at the same time. But will notice that I get few to zero peers for uploading with popular files. There are times that I will leave it seeding for weeks without any uploading. So I end up deleting the torrent so I can move files or free up space because I already made a second copy to sort. Not always the case, but frustrating to not even see a few MB go to anyone. With PeerTube I see my upload working more consistently, but main issue there is just not often that I am watching something that a lot of others (or any others) are also watching.
I personally like large screens due to being able to see more (do have to mess with scaling and font sizes to force browsers). Though I do find that I can only do “serious” work with actual PCs (even tablets don’t “feel” right). Some things make more sense as having a mouse and keyboard are easier to just do things. But other times I can only describe trying to use small screens (including my large phones and tablets) as kind of a digital “claustrophobia” of sorts. Though some of that is because of touch interfaces/UX can’t show as many options/menus and the keyboards take up more of the space.
Though I do hate that we don’t see more compact flagship level options for folks that like them or need them. Apple is like the best option as far as losing fewer functions, and Samsung does still make a point of having a non-plus version of their main yearly releases.
As far as the screen size impacting battery. I think that the opposite is seen from the times I have heard it brought up. The larger body allows for more battery space. I believe that when I was looking at smaller phones for a friend that was thinking that a small screen would help reduce his desire to distract himself from being always on his phone. That one thing I saw people/articles mention was how one down-side for smaller phones was literally how they needed to charge more often to make it through the day. I think the resolution and refresh rates make the most impact on battery. As I remember my S8+ could do like 2k resolution, but in the settings it would mention that battery life might be less than if I picked 1080p. Which would still be an issue if I had the non-plus version.
