Install iOS 11.2.2 for Faster Wireless Charging
If you own an iPhone 8, iPhone 8 Plus, or iPhone X, you skipped iOS 11.2 and iOS 11.2.1, and you wirelessly charge your device, download the iOS 11.2.2 update.
Apple's iOS 11.2 update delivered support for faster 7.5W charging from Qi-Based wireless charging accessories. Wireless charging is only available on 2017's iPhone models.
Now don't go installing iOS 11.2.2 thinking it's going to charge your phone 50% faster. It won't. That said, the change should be noticeable.
If you haven't looked into buying a wireless charger, now's a good time to do so. Just make sure you look for a deal first.
