Buying an old iPhone is a popular choice for many users who want to save costs but still experience the smooth iOS operating system.
However, if you do not check carefully before paying, users can easily encounter hidden iCloud sticks, bottles, hardware errors or build-up items, making "saving" become "losing money and getting sick".
Here are some steps to check before buying an old iPhone, especially a warranty calo or hand-carried item:
Check the external form
Carefully observe the device's edges, glass surfaces, screws and SIM khecas. If the machine shows signs of severe scratches, warping or color changes, it may be an intercepted machine, a replacement of the shell or repair.
Check the Face ID sensor (if any), external speaker, mic, charging port... every small detail can reveal the history of the device.
Check IMEI number and warranty status
Access Settings > General settings > Introductions to get IMEI.
Go to Apple's official website at https://checkcoverage.apple.com to check the warranty status, activation date, and device version.
Verify iCloud and activate
Go to Settings > [ account name] to make sure your device is fully logged in.
For more security, restore the original settings: Settings > Reset > Delete all content and settings.
If the device requires logging into an old account, which means being stuck with hidden iCloud, you should absolutely not buy.
Check the battery and hardware
Go to Settings > Pin > battery status to see maximum capacity. It is best to choose a device with a battery of 85% or more.
Use code *#06# to compare IMEI and matching boxes. You can use an app like 3uTools (via computer) to check repair history, number of charging times, battery status and hardware.
Note
Users are often attracted to cheap prices, but the lower the price, the higher the risk. It is difficult to detect whether a iCloud player or player has components replaced without careful inspection. Never buy an old iPhone without checking in advance.
Always check directly and try all features (camera, calling, speakers, Face ID...) before deciding. Prioritize buying the device from a reputable store with a clear warranty policy, instead of ordering online or individuals who cannot verify.
A good used iPhone comes not only from a reasonable price, but also from a thorough inspection process and the alertness of the buyer.
