How to Check Pre-owned iPhone
10 things to check before buying iPhone in 2024
Buying a pre-owned iPhone can be a smart and cost-effective choice, but it comes with its own set of challenges. Whether you’re purchasing from an online marketplace, a third-party retailer, or a friend, it’s crucial to know what to look for to ensure you’re getting a good deal. In this guide, we’ll walk you through the essential steps on how to check a used iPhone before buying to avoid potential pitfalls.
1. How to Check if the iPhone is Original or a Copy
One of the most important things to verify is whether the iPhone you’re considering is an authentic Apple product. Unfortunately, counterfeit iPhones have become increasingly sophisticated, making it harder to distinguish between a genuine iPhone and a fake one. Here’s how to make sure you’re dealing with the real thing:
- Check the IMEI/Serial Number: Go to Apple’s official website and enter the device’s IMEI or serial number. This will tell you if the phone is registered with Apple and provide details about its warranty status.
- Inspect the Packaging: Original iPhones come with high-quality packaging, including a clear font and proper spacing. The box should also include a unique IMEI or serial number that matches the one on the phone.
- Apple Logo and Build Quality: A genuine iPhone will have a smooth, sleek finish with an Apple logo that is part of the phone’s design, not a sticker. Feel the phone; it should be sturdy, not flimsy or plasticky.
- iOS Features: Fake iPhones may run Android or a different operating system disguised to look like iOS. Go to the Settings > General > About section and check the version of iOS. Only original iPhones run Apple’s proprietary iOS software.
2. How to Check if the iPhone Has Its Original Display
The display is a crucial component of an iPhone, and a replaced or damaged screen can be a red flag. Here’s how to ensure the iPhone has its original display:
- Brightness and Color Accuracy: Original iPhone displays have vivid colors, deep blacks, and bright whites. Compare the screen’s brightness and color with another iPhone if possible. If the colors seem washed out or the brightness is inconsistent, it could be a sign of a non-original screen.
- 3D Touch (for older models): If you’re purchasing an iPhone that features 3D Touch (iPhone 6S through iPhone XS), make sure this feature works as expected. A non-original display may not support this function.
- True Tone Display (for newer models): Check if the True Tone feature is enabled in Settings. If the option is missing, it could indicate a screen replacement that does not support this feature.
- Dead Pixels and Touch Responsiveness: Carefully examine the screen for dead pixels (small, unlit areas) and test the touch responsiveness across the entire screen. A poorly replaced screen may have areas where the touch doesn’t register correctly.
3. SIM Card and Network Functionality Check
Ensuring that the iPhone can connect to your network provider is essential. A faulty SIM card slot or locked phone could render the device useless. Here’s what to check:
- SIM Card Slot: Insert your SIM card into the phone to check if it reads correctly. If the phone doesn’t recognize the SIM, there might be an issue with the slot or the phone might be locked to a specific carrier.
- Carrier Lock Status: Go to Settings > General > About and look for the “Carrier Lock” status. It should say “No SIM restrictions” if the phone is unlocked. If it’s locked, ensure it’s compatible with your carrier.
- Signal Strength: Test the phone’s ability to pick up a network signal. Weak signal strength could indicate an internal hardware issue.
4. Camera Check
The camera is one of the iPhone’s most celebrated features, so it’s important to ensure it functions correctly. Here’s how to check the camera:
- Photo and Video Quality: Take several photos and videos in different lighting conditions. Inspect the quality for any signs of blurriness, discoloration, or malfunction.
- Autofocus and Zoom: Test the autofocus by moving the camera close to an object and then farther away. Make sure the camera focuses quickly and accurately. Test the zoom function to ensure it operates smoothly without distortion.
- Front and Rear Cameras: Don’t forget to check both the front and rear cameras. Take a selfie and a regular photo to compare the quality.
- Camera App Features: Make sure all camera features, like Portrait mode, Night mode, and slo-mo, work as expected. If any features are missing, the camera may have been replaced or tampered with.
5. Battery Health and Performance Check
Battery health is crucial when buying a pre-owned iPhone, as older batteries tend to degrade over time. Here’s how to assess the battery:
- Battery Health Percentage: Go to Settings > Battery > Battery Health. The Maximum Capacity should ideally be above 80%. Anything below this may require a battery replacement soon.
- Peak Performance Capability: Ensure the phone hasn’t been throttled due to battery issues. If the phone indicates that performance management has been applied, the battery may be significantly degraded.
- Battery Drain: Use the phone for a while to see how quickly the battery drains. Rapid battery drain can indicate a worn-out battery.
6. Storage Capacity and Functionality
Ensure the storage capacity meets your needs and that the storage hardware functions correctly:
- Check Available Storage: Go to Settings > General > iPhone Storage to see how much space is available and how it’s being used. Compare it with the advertised capacity to ensure it matches.
- Test File Transfer: Connect the iPhone to a computer and transfer some files to and from the device. Slow transfer speeds or errors can indicate issues with the storage hardware.
- App Installation: Try installing a few apps to see if the phone processes them without issues. Problems during installation can be a sign of underlying hardware issues.
7. External and Internal Damage Inspection
Physical damage can be a sign of internal issues. Carefully inspect the phone for any signs of wear and tear:
- Check for Scratches, Dents, and Cracks: Examine the phone’s exterior, especially the screen and back panel, for any noticeable damage. Minor scratches are common, but deep dents or cracks can be problematic.
- Buttons and Ports: Test all buttons (Home, Volume, Power, and Mute) to ensure they work properly. Also, check the charging port and headphone jack for any signs of wear or debris.
- Internal Damage Indicators: If possible, ask for a look inside the phone (or have a professional do it) to check for water damage or replaced components. Some sellers provide a condition report or photos of the internal parts.
8. Software Check
It’s crucial to ensure that the iPhone’s software is functioning correctly and is not compromised:
- iOS Version: Check that the iPhone is running the latest version of iOS. Go to Settings > General > Software Update. If the phone cannot update to the latest version, it might be too old or have issues.
- Check for Jailbreak: A jailbroken iPhone may have security vulnerabilities. To check if the iPhone is jailbroken, look for apps like Cydia or unusual behavior in the software.
- Factory Reset: Perform a factory reset to ensure that the phone has no hidden issues. This will also remove any previous owner’s data, giving you a fresh start.
9. Check the Accessories
Don’t forget to verify the condition and authenticity of the included accessories:
- Charger and Cable: Ensure that the charger and cable are original Apple products. Fake accessories can damage the phone over time.
- EarPods: If the phone comes with EarPods, check their condition and functionality.
- Other Accessories: Some sellers include cases or other accessories. Verify their condition and value as part of the overall deal.
10. Price Comparison and Seller Reputation
Finally, compare prices and check the seller’s reputation to ensure you’re getting a fair deal:
- Price Comparison: Use online tools and marketplaces to compare the price of the iPhone model you’re considering with similar listings.
- Seller Reviews: If you’re buying online, check the seller’s reviews and ratings. Look for any red flags, such as complaints about undisclosed damage or poor communication.
- Return Policy: Ensure that the seller offers a return policy or some form of buyer protection in case the phone doesn’t meet your expectations.
Wrap Up
Buying a pre-owned iPhone can be a great way to save money, but it requires careful inspection and consideration. By following these steps, you can confidently check a used iPhone before buying, ensuring that you’re getting a device that meets your needs and expectations. Remember, a little diligence now can save you a lot of trouble later. Happy shopping!
