Understand your device with evidence you can review. Battery Analyzer Pro combines information available through public iOS APIs, Analytics and Sysdiagnose files you choose to import, and guided checks you confirm yourself. Review key battery and device data,equipment configuration comparison, follow changes over time, test available hardware, and create a clear device health report—all processed on your device. KEY FEATURES Battery health and technical data Review battery health, reported and design capacity, maximum FCC, Qmax, cycle count, temperature, voltage, current, and operating-time evidence. The app clearly shows each data source and its completeness. Device details, performance, and temperature Review model, device identifier, iOS version, system build, storage, chip, memory, display, cameras, and other identifiable components. Device configuration switching and comparison Multiple configuration files can be easily and freely switched and compared, allowing for easy viewing of configuration differences between different devices at a glance, and easy sharing and exporting of configuration comparison reports. Drain analysis and trends Compare recent Analytics records and review supporting signals such as screen activity, network use, background activity, and thermal state. When evidence is missing, the app says so instead of filling gaps with invented values. Charging speed and power reference Record charge ranges, duration, battery change, foreground coverage, and interruptions. When enough evidence is available, the app estimates net battery-side charging power. It does not claim to measure charger or wall-outlet power. Guided device checks Follow clear steps for display touch, screen uniformity, front and rear cameras, flash, microphone, speaker, receiver, haptics, Face ID or Touch ID, Wi-Fi, Bluetooth, accelerometer, gyroscope, compass, barometer, proximity sensor, and other checks available on your device. Results distinguish automatic evidence from user-confirmed observations. Device health score Get a reference score based on available battery health, temperature, unusual drain, charging performance, guided checks, and Sysdiagnose findings. Data completeness and scoring evidence are shown alongside the result, and missing items are never treated as passed checks. Local PDF reports Create reports from currently available evidence, then preview, store, share, or delete them. Reports distinguish imported evidence, user-confirmed checks, and estimated values. Import tutorials Follow detailed steps to generate, find, share, and import Analytics and Sysdiagnose files. PRIVACY Imported files, analysis results, and reports are processed and stored locally by default and are not uploaded to a developer server. Camera, microphone, photo, or related permissions are requested only when you start a feature that needs them.
