Thanks to its long history developing cutting-edge laptops, Asus brings a great deal of expertise in the gaming space. As a result, the ROG Phone 3 is jam-packed with extra features that really tap into the gaming focus of the handset. Firstly, it features a special 3D vapour chamber and a graphite film layer, delivering a PC-esque cooling system that stops the components in your device from growing too hot over long periods of use.

There’s so much to say about the ROG Phone 3 that it’s hard to fit into one article. Firstly, you get access to a unique ‘X Mode’ that adjusts your device’s performance to fit your gaming exploits. You also get a bespoke ‘Game Mode’ that’s ideal for picking out the sound of enemy players when playing online and a quad-microphone that filters out background nice for crisp party chat.

The ROG Phone 3 is a smartphone after all, so it comes with a triple helping of cameras. There’s Sony’s flagship IMX686 64MP main wide-angle camera, an ultra-wide 13MP secondary camera and an extra macro camera. The handset features advanced software including Pro Video Mode and Free Zoom, and while it’s not quite up to the quality of the latest models from Samsung and Apple, it’s still a very decent trio of cameras that will more than do the job when you’re not gaming.

In terms of alternatives, there’s a decent selection out there. The Razer Phone 2 is easily the strongest competitor out there, with Razor bringing its considerable experience in the PC gaming space to bear in much smaller form. It boasts two large speakers for a more intensive audio experience, a 5.7-inch 1440 x 2560 QHD display and a powerful Snapdragon 845 processor for equally high-performance mobile gaming.

There’s also the very impressive Xiaomi Black Shark 3, which boasts 6.65-inch 1080 x 2340 AMOLED screen, a Snapdragon 865 CPU, a Shark Space mode for gaming sessions that are optimised and notification-free and a 4,720mAh battery that doesn’t quite hold up to the massive battery in the ROG Phone 3, but it will still give you a decent number of sessions throughout the day.
