"It's the best small phone for fans of compact handsets, but the Asus Zenfone 10 could pull users away from Samsung and Google flagships with top-quality performance and battery life. If you can forgive its more limited photography options and the shorter-than-average software support window, the Zenfone 10 is a top choice."

"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."
