If you have one of the wireless chargers officially endorsed by Apple, either the Belkin or the Mophie, and have upgraded to iOS 11.2, have you seen a marked improvement in how fast your iPhone 8/8+/X charges? I had a RavPower wireless charger (the up-right, standing version for $19.99) connected to a 12W wall charger and saw no difference after upgrading to 11.2. I've now gotten the $59.95 Belkin charger sold at the Apple Store, and have seen a pretty dramatic improvement. Unfortunately, I haven't made any controlled measurements of charging times to compare the two, so I was curious what others have experienced.
