Working just fine for me,
both on iphone X and iphone 11 pro max
What’s the percentage? You haven’t perchance hit the ’smart’ 80% charge limit have you? Not really new to 13.4, I think, but bit us here recently.
it was at 80%, yes! what the hell does that smart limit mean exactly???

yes, this i'm aware of, but why does it stop charging at 80% during a time that does not fall under my "usual" times. besides - only on a wireless charger - when i plug it in - it charges fine.
There's no consistent answer that I’ve found, but similar questions have been raised since the feature came out. You must have a consistent regular schedule. Change it for even a day and it can affect the feature. Some wireless charges apparently work and some don’t. Even some power blocks for wired work and some don’t. Bottom line for me is I’ve got it turned on but don’t pay attention to it.
