Tool Open source
MiniWatts is an iPhone battery, charging, and thermal monitor built with Apple's private iOS APIs. It reads the phone's power-management sensors to show charger input, power reaching the battery cell, heat-related power, temperature sensors, and USB Power Delivery information, with Power, Thermal, Adapter, and History views. It also provides Home Screen and Lock Screen widgets, a charging Live Activity, and a floating Picture-in-Picture meter that can keep recording while another app is open or the screen is locked.
MiniWatts is distributed as a sideloaded IPA because its private API usage prevents App Store distribution. It requires an iPhone running iOS 17 or later, includes no network code, and can be installed using tools such as Sideloadly, AltStore, SideStore, or Xcode. Sensor availability and meanings vary by iPhone model; wireless charging input current, battery health, and cycle count are unavailable, while discharge power and charging holds may be estimated or inferred. The project is licensed under Apache 2.0.
