How to check if a used iPhone has replaced parts: Parts and Service History

Newer iPhones keep a record of repaired parts that any buyer can see in Settings. Here is how to find it, what Genuine, Used, Unknown and Unverified mean, and which models show which parts.

On the seller's iPhone, open Settings > General > About. If the phone has been repaired and runs iOS 15.2 or later, you will see a Parts and Service History section listing the replaced parts with a label next to each. Genuine or Used means Apple parts and processes were used, while Unknown or Unverified deserves questions and usually a lower price.

• 1. Open the About screen: Ask the seller to open Settings, tap General and then tap About. Scroll down slowly. If the phone has had a repair that iOS tracks, a Parts and Service History section appears here.
• 2. Check which parts your model can report: iPhone XR, XS, XS Max and iPhone SE (2nd and 3rd generation) report only the battery. iPhone 11 models report the battery and display. iPhone 12 models and later report the battery, display, logic board, front camera and rear cameras. Anything outside that list will not show up, so a missing section is not proof the phone is untouched.
• 3. Read the label next to each part: Genuine means the repair used real Apple parts and Apple's process. Used means a genuine part that came out of another iPhone. Unknown is a warning sign: iOS could not confirm the part, which happens with copies, faulty or modified parts, and repairs that were never paired to the phone afterwards. Unverified appears for a logic board that has been replaced or taken from another iPhone, and can affect features like Apple Pay.
• 4. Tap a part for the service date: If the phone is online, tap a listed part to see more details, including when the service was done. Compare that date with what the seller told you. Only the most recent service for each part is shown.
• 5. Watch for Finish Repair: If you see Finish Repair next to a part, the repair was never completed in Apple's Repair Assistant. Until it is, Face ID or Touch ID may not unlock the phone, and the part may not perform at its best. Ask the seller to finish it before you pay.
• 6. Cross-check the battery screen: Go to Settings > Battery > Battery Health (Battery Health & Charging on iPhone 11 to 14). If it says it cannot verify a genuine Apple battery, the capacity and cycle figures may not be accurate. On iPhone 15 and later, the date of first use here also helps you judge the phone's age.
• 7. Test the parts that were replaced: If the display was changed, check touch across the whole screen, brightness and True Tone. If a camera was changed, open the Camera app and try every lens and the front camera. Set up Face ID or Touch ID with your own face or finger to see that it works.
• 8. Adjust your offer: A phone with Genuine or Used parts from an authorised repair is usually fine to buy. Unknown or Unverified parts can affect how the phone works and what it is worth later, so either negotiate firmly or walk away. Ask for the repair bill if the seller has one.
