"The OnePlus 11 isn’t a perfect device, but it’s another big step in the right direction for the company. A great display, incredible performance, and some of the best battery life I've ever seen on a phone helps make this one of the best OnePlus devices in recent years."

"All told, Samsung nailed it with the Galaxy S21 Plus. It has most of the strengths of the smaller S21 in a bigger package. It’s got a lot going for it. If you’re coming from an older device, like the Galaxy S10 series, this is a solid upgrade."
