The OnePlus 15 is a perfect phone, according to my review score, and I couldn’t ask for more. It beats my best expectations across key criteria like display quality, battery life, and overall performance. Of course, some phones are better in one or two specific metrics, but none in every way.
The Galaxy S26 won’t be Samsung’s best phone ever – nobody would buy the Galaxy S26 Ultra if it were. Still, could the Galaxy S26 Ultra be a perfect phone, with a perfect 5/5 score on TechRadar.com? Well, to reach perfection, Samsung shouldn’t just focus on copying what OnePlus does best, because it's already doing those things pretty well.
