About this app

CPU-Y is a device info and hardware diagnostics app: live CPU, SoC, RAM, storage, battery,
sensors and network information, 19 hardware tests, and a full system benchmark.

All system info is read directly from your phone and shown as-is. Nothing is invented: when a
value cannot be read on your hardware, CPU-Y hides it instead of guessing.

■ LIVE DEVICE INFO
• CPU info — per-core frequency, governor, cluster layout, architecture, instruction sets
• SoC / chipset — processor model, cores, manufacturing process, peak clock
• Memory info — RAM and storage capacity with live usage
• Battery info — level, current (mA), voltage, temperature, battery health, charging power
• Thermal — every temperature sensor your device exposes, updating live
• Network info — Wi-Fi details, signal, IP address, live download and upload speed
• GPU, display, cameras, sensors, input devices and full device identity

■ 19 HARDWARE TESTS
The things a spec sheet never tells you — ideal as a used phone checker before you buy:
• Screen test — dead pixel test, colour banding, backlight, touch dead zones, multi-touch
• Audio test — loudspeaker, earpiece, microphone, vibration
• Sensor test — proximity, light sensor, accelerometer, fingerprint, buttons, flashlight
• Power & ports — charging, headset / USB-C
• Connectivity — GPS lock, NFC
Mark each hardware test pass or fail as you go; results are saved.

■ BENCHMARK
One total score plus separate results for single-core CPU, multi-core CPU, GPU fill rate,
memory bandwidth and a UI workload — so you can see which part of the phone is actually fast.

■ SYSTEM TOOLS
Stability and throttle test, GPU stress test, storage speed test, FPS meter, sensor monitor,
data logger, per-app data usage, app analyzer, Wi-Fi scanner, Bluetooth scanner, network mapper,
GPS / GNSS status, USB check, compass, streaming readiness (DRM / HDR) and a device
authenticity check.

■ MONITOR YOUR PHONE ANYWHERE
• Home-screen widgets — RAM, storage, and battery & RAM
• Floating monitor — a draggable live CPU, RAM and temperature window over other apps
• Status-bar monitors — live network speed, battery temperature and current
• Quick Settings tile for an instant CPU and temperature snapshot
• Export a full device report to share

■ BUILT TO BE READ
Dark, light and OLED themes, accent colours, °C or °F, adjustable refresh rate.
Available in English and Japanese.

■ HONEST ABOUT DATA
Your hardware readings stay on your device — they are never uploaded. CPU-Y is free and
supported by ads, and it sends anonymous crash reports so bugs can be found and fixed. Ads
never appear on the benchmark or stress-test screens, so they cannot affect the numbers you
are shown.
