iOS 13 and performance

The iPhone 11 Pro battery consistently lasted us more than a day during our testing, often stretching close to a day and a half, even with heavy use. When enabled, the iOS 13 low-power mode really extends the life of this battery.
Apple claimed that the iPhone 11 Pro can last four hours longer than the iPhone XS, and true enough, we did see a noticeable increase over last year's 5.8-inch phone. But the bigger the phone, the larger the battery Apple is able to fit in; the 6.1-inch iPhone 11 and 6.5-inch iPhone 11 Pro Max lasted longer.
The fact that the 18W charger and lightning-to-USB-C cable are included in the box is a big deal. Our iPhone 11 Pro went from 0% to over 50% in 30 minutes, whereas the old 5W charger, which hung around for far too long, took forever to reach this point.
We're still dealing with slow 7.5W wireless charging speeds, and the rumored reverse wireless charging feature never panned out as a way to charge your Apple Watch or AirPods from the back of the iPhone 11 Pro. There's always hope for the iPhone 12.
