How to tell if an iPhone has been opened or repaired

The clearest way to tell whether an iPhone has been opened is Parts and Service History in Settings. Battery and screen messages, the True Tone option, the screws and the screen edge also give clues. Check them together when buying second-hand.

Key points
  • Parts and Service History in Settings › General › About lists replaced parts.
  • Check Battery Health for an “unknown part” or service message.
  • If the True Tone option is missing, the screen may have been replaced.
  • Scratched screws next to the charging port can mean the phone was opened.
  • Decide on all the checks together, not a single sign.

01Checking in settings

  1. Parts and Service History. If this section appears in Settings › General › About, replaced parts such as the screen, battery or camera are listed.
  2. Battery health. In Settings › Battery › Battery Health & Charging, a message about whether the battery is genuine may appear.
  3. True Tone. If True Tone is missing in Settings › Display & Brightness, the screen may have been replaced.
  4. Face ID / Touch ID. If it does not work, the related parts may have been replaced or damaged.

02Checking the outside

03Second-hand checklist

  1. Check Parts and Service History.
  2. Check battery health.
  3. Test the screen with solid colours and the touch test.
  4. Test Face ID, the cameras, the speaker and the microphone.

FAQ

Frequently asked questions

01

If Parts and Service History is missing, was the iPhone never opened?

If there is no replacement record to list, the section does not appear. Still, check the outside and the other signs too.

02

Is it a problem to buy a repaired iPhone?

Not in itself. The type of part, the quality of the work and the device’s overall condition matter.

03

Why does an “unknown part” message appear after a repair?

It can appear if Apple does not recognise the replaced part. The message usually does not stop you using the device.

04

What paperwork should I ask for when buying a used iPhone?

Ask for an invoice or a sales contract with ID; service records, if any, also show the device’s history.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
