Some users have noticed their phones won't charge if the screen is off when they plug in a lightning cable.
If you've got an iPhone XS and XS Max that doesn't appear to charge correctly, Apple's got a fix coming for you.
Some users have reported their new phones won't charge when plugged into lightning cables when their screens are off. The iPhones did, however, charge when using wireless charging or when the screens were on. For those charging with the screens off, the phones will eventually charge even though they don't begin immediately when plugged in.
Apple's next software update, iOS 12.1, will solve the problem. It's currently available in beta and will arrive on all iPhones and iPads later this fall.
Apple's beta program has been open to the public since early 2015, but it's only recommended to people who don't rely on a single iPhone or who are willing to put up with some possible glitches.
If you're not quite ready to make the jump into beta testing, you can unplug your lightning cable and plug it back in to kickstart the charging. Even if it doesn't show the phone is initially charging, it eventually should start. Otherwise, you'll have to wait until iOS 12.1 hits the market, and Apple hasn't yet said when that will be.
Whenever Apple releases new software and new devices, there are often bugs that don't show up until millions of people are using them. In the case of last year's iOS 11.1, there was a glitch that prevented some users from typing the letter "i." Instead, it would autocorrect to the letter "A" and a unicode symbol. Apple released iOS 11.1.1 to fix the issue.
