CPU-A — Device and processor inspector

CPU-A is a free Android utility by Gokhan Gencer that reveals in-depth specifications for your phone or tablet. It reports processor, device, system, battery, and sensor details and includes several on-device monitoring tools. The app also uses a couple of network permissions for online checks and usage statistics.

Processor details and monitors

• Per-core clock speeds and real-time CPU usage monitoring
• Detailed CPU model and processor identifiers (part numbers, revisions)
• Architecture verification and Cortex/core family detection
• Hardware IDs and serial numbers, plus vendor-specific checks (e.g., Kirin detection)
• Built-in core analyzer and other CPU diagnostic tools

Device specifications and physical profile

• Screen resolution and display characteristics
• Brand and model identification, with bootloader information
• Installed RAM and available storage totals
• Quick phone-specs summary tool for an at-a-glance overview

System, firmware and runtime information

• Kernel version and build number details
• Android release and API level, along with runtime environment info
• Root status detection and Android platform specifications
• Cellular capability notes and other radio-related attributes

Battery status and thermal data

• Current battery level and reported capacity
• Charge state and overall battery health indicators
• Battery chemistry/technology, voltage, and temperature readings
• Separate CPU temperature reporting for thermal monitoring

Sensors, connectivity and diagnostic utilities

• Wi‑Fi, Bluetooth and GPS status indicators
• Motion and environmental sensors: accelerometer, gyroscope/rotation vector, magnetic field, compass, barometer/pressure, light, proximity
• NFC support and other radio features
• Embedded diagnostic utilities such as CPU and GPU monitors (CPU‑Z style reports, cooler/monitor tools and stress/test functions)

Permissions required

• INTERNET — used for online validation and any remote lookups
• ACCESS_NETWORK_STATE — used to collect basic usage/statistics about network availability

Final thoughts and an alternative

If you want a straightforward, reliable app for identifying your device’s processor and system details, CPU-A is a solid choice.
Suggested alternative: HappyMod (free), which some users prefer for accessing modified app packages and additional app discovery features.
