The iPhone 11 pro comes bundled with a fast wired charger. It can really charge your iPhone faster, but if you’ve equipped your work desk and bedside tables with wireless chargers already, you would be disappointed to know that Apple hasn’t updated the wireless charging speed on iPhone 11 and 11 Pro. Both devices still charge the same as previous iPhone models at 7.5 watts wirelessly.

Mobile devices in the Android world support 10 watts wireless charging as standard and some even support 15 watts wireless charging. Compared to that, 7.5 watts is very sub standard for a flagship iPhone model.

Apple doesn’t mention the iPhone 11 and iPhone 11 Pro wireless charging speed on the specs pages but we found it on a support page that wireless charging on iPhone 8 and later devices is still capped at 7.5 watts only. Even with the latest iOS 13 update.

Your iPhone 8 or later features integrated wireless charging that allows for an easy and intuitive charging experience. Your iPhone has a glass back that works with Qi-certified chargers that are available as accessories and in cars, cafes, hotels, airports, and furniture. Qi is an open, universal charging standard created by the Wireless Power Consortium (WPC). 

There are many Qi-certified chargers available in the market that charge an iPhone with the latest version of iOS at rates up to 7.5 watts. These chargers are available at the Apple Online Store and Apple retail stores.

That said, the iPhone 11 and 11 Pro are still compatible with any wireless charger you may have. Whether it be a 5W charger, or a 15W one. All Qi-certified wireless chargers are supported by iPhone 11.
