While almost all high-end smartphones are capable gaming machines, few make it a priority. Lenovo's Legion Phone Duel 2 is an exception. Built specifically for gamers, it splits its battery in two, placing its Snapdragon 888 5G processor — with up to 18GB of RAM and 512GB of storage — in a central housing that includes a twin turbo-fan cooling system and a liquid cooling area. Also in the middle is a 64-megapixel main camera and 16-megapixel telephoto camera, while the battery covers integrate console-like touch controllers, offering up to eight virtual trigger areas, as well as dual x-axis haptic feedback motors. Out front, there's a 6.92" HDR AMOLED display with a 144 Hz refresh rate to keep up with the action, a pop-up camera for live streaming, and Dolby Atmos front-facing speakers for sound to match the visuals.
