Buying secondhand electronics, especially used iPhones, requires careful consideration and a good overhauling to ensure one gets a reliable device.
Here is a short, detailed checklist to help one in navigating that process:.
Things to Check Before Buying a Used iPhone
Check the condition.
Before committing to the purchase, request pictures of the iPhone from every angle and close-up shots, if possible. Check for any existing scratches, dents, discoloration, or marks to the camera lens or parts that may be involved with wireless charging.
Proof of Purchase
Request a duplicate copy of the original receipt, which is essential to verify previous ownership and warranty status. Check that the name of the seller matches the one on the receipt and verify the date of purchase. In case there is no receipt, consider the risk of not being able to trace the ownership history of the device.
IMEI Number
Ask the seller for assistance with the IMEI number—tap Settings > General > About or simply *#06#. Match this to your Proof of Purchase and confirm device specification and history using online tools such as IMEI.info.
Serial Number
Like the IMEI, the serial number can be found on the Settings > General > About screen and it can also be used in verifying the coverage status and device specifications, which you can then match on Apple’s coverage page.
Partial Authenticity
Ask if it has ever been repaired and by whom. Recommendation In case the owner had a device repaired elsewhere, it may have non-Apple parts, which may impair performance and longevity. Touch-test
Ask for a live demo of the physical buttons and touch screen performance. Ensure that all of the buttons respond appropriately and that basic gestures like swiping, zooming, and tapping work without a hitch.
Camera Test
Ask the seller to take pictures with both the front and back cameras and make sure that the images are clear and there is no damage to the camera hardware.
Speaker Test
Test the speakers: Ask the seller to turn up the volume all the way, then either play music or call a number. Listen for any static or distortion. Test the vibrate function by putting it on a hard surface and testing the vibrations.
Microphone Check
Request the seller to record a phrase and have it played to check for the microphone, or make a call and check the quality of the sound.
Port Checks
Test to see that all the ports are working. Conform with the seller to test out the charging port and, if any, the headphone jack by plugging in respective accessories.
