Troubleshooting iPhone problems can be a daunting task sometimes considering how complicated they are. It’s easy to overlook the simple things and on occasion you may replace parts that don’t need replacing. Batteries are no exception. I have seen technicians often replace batteries when they may not necessarily need to be or ignore the fact that they could be the cause of the issue at hand. To remedy this I designed a basic iPhone battery charging breakout board system. The system can charge a battery, has the option for expansion to support newer/other batteries and breaks out the battery status pins which can be read from a microcontroller or some other means. It consists of 6 battery connector boards (iPhone 4, 4S, 5, 5S/C, 6, 6+) and a main charging board.
