Apple will be enabling faster 7.5W wireless charging on the iPhone 8, iPhone 8 Plus, and the iPhone X with the upcoming iOS 11.2 update. Right now, wireless charging on all the three handsets is capped at 5W.
Apple had previously mentioned that it would enable faster Qi wireless charging on its 2017 iPhone lineup with a future update.
At 5-watt, the wireless charging speed on the iPhone 8 and iPhone X matched the wired charging speeds for the devices when charged using the bundled charger. With the bump in power post the iOS 11.2 update though, Qi wireless charging on the iPhone X/iPhone 8 will be faster than wired charging.
The speed improvement is not going to make a world of a difference though. As per a tip sent to MacRumors, the iPhone X charged from 46 to 66 percent in 30 minutes when charged with a compatible 7.5W Qi charger. In comparison, when charged with a 5W wireless charger, the iPhone X charged from 46 percent to 60 percent.
Flagship Samsung devices feature Qi 1.2 standard which supports fast wireless charging and charge at a rate of up to 15W.
Do keep in mind that your Qi wireless charger also needs to support wireless charging of up to 7.5W. Wireless chargers that Apple sells on its stores from Mophie and Belkin do support the faster charging speeds. However, many other Qi chargers don’t especially the ones that you can grab for pretty cheap from Amazon.
Apple will likely release the final build of iOS 11.2 before the holiday season so as to ensure that iPhone 8 and iPhone X owners are able to enjoy faster charging speeds on their devices.
