Source code for small iOS app to show real-time charge rate, thermals, etc.

Shows 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).

I created this 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.
