From the README
ios-charging-monitor ChargeSpeed: live charging power on an iPhone, read from the phone's PMU and charger sensors via private APIs. Build it yourself, install on your own phone. Cannot ship on the App Store because of the private APIs it uses (see below). Why To compare chargers and cables. iOS shows a lightning bolt and nothing else. Seeing the wattage exposed a few bad charging setups I'd been using. On a wireless charger it shows the profile iOS reports and the watts that actually reach the battery, which don't always match. And it finds the sweet spot on a wireless charger with no magnets, like a car tray: slide the phone around with the live watts on screen until the number peaks.
