In rare cases, the screen plug-in attempt to charge the phone will cause a complete loss of response, that is, the crash.
At present, the Apple Support Forum, the famous Apple site Macrumor forum, Reddit, push the principal place can see the iphone XS Series users feedback this issue, but it is not clear how much scope of impact.
