All three recently-revealed models, the iPhone 8; iPhone 8 Plus; and iPhone X, all support wireless charging using the Qi standard. It means that iPhones are now compatible with a number of chargers available in the market. But iPhone Qi charging is currently limited to 5W, or the slowest wireless charging speed. The company is presently working on the iOS 11.2 — this update is going to support 7.5W charging, as MacRumors spotted.

When new iPhone models were introduced to the public, Apple said that they would only support 5W charging for now.

Apple is currently testing iOS 11.2 with beta testers, and this update unlocks wireless charging speed. 5W wireless charging is more or less as fast as using the charger accessory that comes with the iPhone.

MacRumors tested iOS 11.2 with a 7.5W charger and a 5W charger. After the update, wireless charging with a 7.5W charger was 43 percent faster.
