Apple Intelligence is now available on iPhone, iPad, and Mac!
After I plug my Iphone 12 to charge with the fast charge 20W charger during the night, the battery maintains around 40% but does not goes to 80 with the optimized charge and slowly decrease to 38%. After 6 hours (when I woke up) I realize that the iphone does not charge.
See picture of the battery charging cycle.
This happens at least once a week.
iPhone 12 Pro Max, iOS 16

hello dawngreg08,
its weird because you can see in the graph that the phone was receiving energy but the charge does not goes up to 80% as should be on optimized charge.
My Iphone 12 Pro Max does not charge while plug during the night, just maintain the charge
