How do I check my phone's specs?

On Android, open Settings then About phone for the model, Android version and build number; RAM and storage appear under Settings then Storage. On iPhone, open Settings then General then About. For the full picture — CPU model, sensor list, screen density, battery health — a device info app reads far more than the settings screens expose.

How do I find out how much RAM my phone has?

Android hides this by default: enable Developer options, then look under Settings then Memory, or use a device info app. iPhone never shows RAM anywhere in Settings, so you need either a spec lookup for your exact model or an app that reports it.

What is the difference between total and available storage?

Total storage is the chip capacity, such as 128 GB. Available storage is what is left after the operating system, preinstalled apps and the file system take their share — typically 8 to 15 GB less than advertised. Manufacturers also count 1 GB as 1,000,000,000 bytes while the phone counts 1,073,741,824, which widens the gap further.

Can I check specs without installing an app?

Partly. The Settings app covers model, OS version and storage. For screen resolution, pixel ratio, CPU core count and browser capabilities you can use a browser-based checker such as our device specs tool, which reads what the browser exposes without installing anything.

How do I check what sensors my phone has?

Neither Android nor iOS lists sensors in Settings. A device info app enumerates them directly from the system — accelerometer, gyroscope, magnetometer, proximity, ambient light, barometer and so on — and usually lets you see live readings to confirm each one works.

How to Check Your Phone Specs & Device Info

5 min readUpdated 2026-10-06

Short answer: on Android, Settings → About phone covers model, Android version and build; storage lives under Settings → Storage. On iPhone, Settings → General → About. Neither shows RAM, CPU model or the sensor list — for those you need a device info app or a browser-based checker.

Try our free device specs tool right in the browser, or install the Device Settings Information app for complete specs and quick settings access on the device itself.

This guide covers the how-to for both platforms; if you're switching between an iPhone and an Android phone and want the two compared side by side, see iPhone vs Android: how to find device info on both.

Where to Find Each Spec: Android vs iPhone

Spec	Android	iPhone
Model & OS version	Settings → About phone	Settings → General → About
RAM	Developer options → Memory, or a device info app	Not shown in Settings; needs a device info app or model lookup
Storage	Settings → Storage	Settings → General → iPhone Storage
Battery health	Varies by manufacturer, or a device info app	Settings → Battery → Battery Health & Charging
Sensor list	Not listed in Settings; needs a device info app	Not listed in Settings; needs a device info app
