New App

MiniWatts reads the iPhone's own power management sensors and shows what is actually flowing: charger input in watts, what reaches the battery, rail voltages and currents, every temperature sensor placed on a map of the phone, the USB-PD profiles the charger offers, and a history of each charge. It reads private system frameworks, so it is sideload-only and can never be on the App Store. It was built and verified on an iPhone Air; sensor names and scaling differ between models, so some readings may be wrong on yours. Includes a Home Screen and Lock Screen widget, a charging Live Activity and a floating Picture in Picture meter. The widget and the Live Activity live in an app extension: signing it takes one more App ID, and LiveContainer cannot run extensions, so installed there MiniWatts has neither.
