iPhone Battery Charger / Tester

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.

Use Cases

Sometimes a battery will show no voltage when tested with a multimeter. It is possible that the LiPo cell is in fact completely dead although this typically means the battery has gone into protection mode. This can be caused by various reasons including liquid damage short, over voltage/current lockout and under voltage lockout. My battery system can revive or re-activate a battery that has entered protection mode by simply connecting it to the main charging board.

From time to time I will get a phone in for repair with a (very) low battery and will not boot up because of that fact. The repair may be as simple as a screen replacement. With this battery system you can leave the battery in the case and connect it to the charger while you move the home button, front sensor flex to the new screen. You could even create a short extension cable from the battery board to the mainboard.
