If the "message" that you are referring to indicates that you have an Unknown Part.....the shop installed the wrong battery.
That message might go away in a month or two, or it might not. Battery Health settings now may or may not work
Unfortunately, if your phone requires service in the future, Apple will not touch the phone.
