Steps
Also include

  1. Open Settings and tap General

    Open the grey Settings icon and tap General.

  2. iPhone screen: Tap About

    Tap About

    About is the first row under the General heading.

  3. iPhone screen: Read the iOS version and model

    Read the iOS version and model

    iOS Version shows the software on the phone. Model Name is the name used in shops, such as iPhone 17e. Tap iOS Version to see when the update was installed and what it brought.

  4. iPhone screen: Read Capacity and Available

    Read Capacity and Available

    Capacity is the size of the phone, for example 128 GB or 1 TB. Ours showed 256 GB with 222,33 GB available. Available is the free space right now. If Available is under about 5 GB, updates and the camera start to struggle.

What changed: new screenshots from our own iPhone 17e on iOS 27.0.1, dark mode, and the wording checked against those screens.

About this guide

The About page answers the questions support staff and second-hand buyers ask most: which iPhone is this, which iOS is on it and how much space is left.

The pictures are our own, from an iPhone 17e on iOS 27.0.1, in dark mode. The name and serial number are blurred.

Good to know

The Serial Number on this page is what Apple asks for when you check warranty or book a repair. Hold your finger on it to copy it. Do not post it publicly.

To see what is using the space, go back to General and tap iPhone Storage. The list is sorted with the largest apps first.

To check for a newer iOS version, go back to General and tap Software Update.

In short: Settings, General, About. iOS Version for the software, Available for free space.
