I have had issues with two Apple battery cases for my Max. I have had the cases replaced each time. And each time I go in...the genius says that Apple doesn’t intend for the phone to be in the case all the time. For example...if I am at Disneyland with my kids...I should use the phone battery and then put the phone in the case to recharge the phone. This makes no sense to me. I am not going to use my phone out of the case....or have to bring two cases with me... Also...they said to take it out to charge the case and phone separately at night. No...not going to do that either. If apple didn’t want the battery also charging the phone then they could have added a switch. My opinion is the battery case should simplify my charging not add additional work.
