Samsung S25 Ultra vs. OnePlus 13: Please help me choose my next primary device

My requirements :

1) A perfect display for media consumption 2) Runs editing apps like Capcut and Alight motion smoothly 3) uninterrupted software experience 4) useful hidden features like (idk even exactly know what I'm looking for here, but-) it's easier to make notes etc 5) Runs like butter for 4-5 years (since I'm not planning to replace it till 4 years atleast) 6) 1 day+ battery back-up and battery doesn't age badly

That's pretty much it (yes I don't care about the camera at all)

The main reason I have doubts about the Samsung, even though I've heard a lot of good things about its S line, is that it's practically the same phone as the OnePlus on paper but with that price difference, I could get an iPad M2 as well, which means I’d end up with both an iPad M2 and a OnePlus (haha).

However, if the OnePlus doesn’t last as long (4-5 years) as the Samsung which I suppose is known for it's longevity, then it's worth nothing.

One plus side of the OnePlus is its fast charging, but I’m not sure if that could negatively affect its battery health in the long run.

Imp note: I’m not really into modern tech these days, so forgive me if what I'm asking out of these phones is too much to ask for.

Now that everything is clear about what I’m looking for, what do you suggest? comment below 👇🏻🙏🏻
