Smart Battery Case Charging Time

26 Jan 2019

Today I let the phone and case drain down completely - to the point where the iPhone shut down. Using a 30w USB-C Lightning connection, these are the times it took to charge. What’s really interesting is that with USB-C, the case and phone charge in parallel.

Update:

When I left the iPhone unattended all night, by 10:30 am, the battery had dropped by 10%. I think this because I had Dark Sky constantly using Location Services. I’m also going to make it a practice now to have the XS Max on Low Power Mode unless I’m away from the house and keep Bluetooth disabled. This is because I have my computer and iPad, should I need them.
