"If you’re hunting for the best Android camera phone at this price, and one that doesn’t skimp on specs the OnePlus 9 is worth considering. Courtesy of a partnership with Hasselblad, the cameras offer better color correction, and both regular and ultra-wide photos look great. The OnePlus 9’s battery fully charges in under 30 minutes over a cable, and in 45 minutes using wireless charging. If you hate waiting for hours to charge your phone, you'll love the OnePlus 9."

Allison Johnson | February 2023
"The 6.1-inch S23 is the best reasonably sized Android phone on the market in the US, partly because almost every other Android phone sold here is gigantic. But it’s also a really good device, with a battery that gets through a full day more comfortably than its predecessor. The Snapdragon 8 Gen 2 chipset responsible for some of that battery performance improvement is slightly different — and slightly faster — than the 8 Gen 2 in other Android flagships."
