While the iPhone 8, 8 Plus and X are currently limited to 5-watt wireless charging speeds, MacRumors reports the release of iOS 11.2 will boost that speed to 7.5 watts. The speed increase will require a charging pad capable of achieving those speeds, and not all are up to the challenge. A test showed that the Belkin wireless charger currently sold by Apple—which supports 7.5 watt charging—did charge an iPhone X running the iOS 11.2 beta faster than a 5-watt charger, even proving faster than a wired 5 watt connection. Apple is expected to release its own AirPower wireless charging mat later this year, which will be large enough to allow users to charge iPhones, Apple Watches and AirPods on a single pad, but Apple hasn’t released specs on how fast it will be able to charge the devices. The Qi standard used in Apple’s wireless charging technology is capable of handling up to 15 watt speeds.
