If my phone is always 100 procent is that bad
With my Apple battery case my phone is always 100 procent. Is that not bad for the battery ?
iPhone XR
Your iPhone XR and iOS will manage the total amount of charge drawn from your Battery Case and from the iPhone's internal battery. So, the answer to your question is a NO. It is not bad for the battery because your iPhone will manage the proper charging process.
