Do you have to charge two batteries?

How are the batteries interconnected? Do you simply charge the phone as usual or do you charge the battery back separately?

  • You Charge the phone "as usual". It replaces the stock lighting connector for another one. Both batteries are charged simultaneously but when you use it, the battery in the case is used first (iPhone battery's remains at 100%).
