Has problem with functionality of battery in my airpods pro. I found it strange that battery drains completely only when I'm taking out airpods from case. So I put it with some battery left to case and there is nothing next day. Is it normal ? I found it strange, even if I would put to empty case there should be some left and drain out during usage. I use airpods everyday for about hour maybe less and always battery is empty when taking out from case not during listening to music
