Razer is jumping into the crowded world of iPhone cases, but with (what else?) a decidedly gaming-oriented twist. The company's newly introduced Arctech and Arctech Slim rely on a custom-developed Thermaprene material and perforations to transfer heat away from 2018 and newer iPhones (including the iPhone 11 line) as well as the Razer Phone 2, theoretically preserving your handset's performance and battery life while you're in a frenzied game session. The jury's still out on that, but Razer's tests showed the phone staying within recommended temperature limits for two hours where an unspecified rival case saw the phone run hot within 20 minutes. If nothing else, the Arctech won't make things worse like some cases can.
