Hey everyone! I just bought my iPhone 7 an Apple branded charging case. I realized that once my phone is in the case it automatically charges my phone without any kind of switch to turn it off. It's kinda neat to have my phone charging all day but I can't help but wonder, is my iPhones battery going to deteriorate since it's technically plugged in all day? I looked through the internet but found nothing on the matter. Let me know what you think. Maybe I should only use the case when my iPhone battery is low? Thanks everyone!
