CPU Info: Device & Battery

See what your phone actually is — and get a battery reading you can trust.

Most device-info apps will show you a battery health percentage no matter what. This one won't. It tries four methods in order, tells you which one produced the number, and says "not determinable" when your device genuinely doesn't expose enough to measure it. A number you can check beats a number that looks confident.

HONEST BATTERY HEALTH

• Uses your device's own state-of-health reading first, where the hardware provides one

• Falls back to measured full-charge capacity against design capacity

• Learns from real charge sessions — and ignores small top-ups, because extrapolating capacity from a 3% charge is guesswork

• Names the method behind every figure, so you can judge it

• Flags multi-cell packs instead of silently halving or doubling your capacity

• Live current in mA and power in watts while charging

• Charge history, with screen-on and screen-off drain since you unplugged

EVERYTHING ABOUT YOUR HARDWARE

• Processor: model, cores, live per-core frequency, clusters, architecture

• GPU: renderer, vendor, OpenGL ES and Vulkan support

• Memory and storage, including external volumes

• Display: resolution, density, refresh rates, HDR support

• Cameras: resolution, aperture, focal length, sensor size

• Sensors: every sensor your device reports, with live readings

• Network: connection type, link speed, IP addresses, DNS

• System: Android version, security patch, kernel, uptime

• Thermal: live temperatures from every zone your device exposes

HARDWARE TESTS THAT EXPLAIN THEMSELVES

Check your touchscreen, display, multi-touch, speakers, microphone, vibration, flashlight and more. When something fails you get a plain-language explanation of what it means and what to try — not a red X with no context.

WIDGETS AND A FLOATING MONITOR

Home-screen widgets for battery and system state, plus an optional floating overlay that keeps CPU and memory visible while you use other apps. No paywall on any of it.

EXPORT AND SHARE

Generate a full readable report of your device and test results. Useful when you're selling a phone, buying a used one, or sending details to support.

BUILT TO RESPECT YOU

• No account, no sign-in, no server of ours — nothing is uploaded

• The microphone test analyses sound levels on your device and records nothing

• No location permission, so no SSID or scan access is requested

• Privacy options are one tap away in Settings, not buried

Supported by ads. An optional one-time purchase removes them — it unlocks nothing else, because nothing else is locked.

Some values depend on what your manufacturer chooses to expose. Where a figure isn't available, this app says so rather than inventing one.
