PhoneVitals is diagnostic software for iPhones that performs hardware tests via USB connection. The software communicates with internal chips like the battery gas gauge to extract detailed hardware data and generates a cryptographically signed report. Each report includes a QR code that allows customers to verify findings on the PhoneVitals website. The software is compatible with Windows 10 and 11 and supports iPhone models from 6s through current releases. PhoneVitals decodes kernel panic logs, identifies battery degradation, and detects fraudulent devices by cross-referencing serial numbers. The platform measures abnormal power drain to identify shorted capacitors and other hardware faults. PhoneVitals operates without jailbreaking, installation, or disassembly of the device. The software uses real-world telemetry for calibration. Reports include raw evidence alongside diagnostic findings so technicians and customers can review the data behind each conclusion.
