Does the Apple smart battery case (for iPhone 7) charge the phone constantly?

Does this Apple smart battery case charge my the iPhone 7 even when it is at 100% battery or does it stop at a certain percentage?

    It charges all the time as long as you have charge in the case. I'm now wondering if this is good for the iPhone battery. I would have to think it would cause your iPhone battery to not have as long of a life span for the life of you phone.

  • These batteries won't get a memory. They are lithium ion. Battery management is part of the charger built in to the phone and is independent of what external source is used.
