Before buying a used iPhone, perform critical checks to avoid potential issues. Scams are frequent in the online market, so stick to reliable sources like Amazon or Best Buy. Be sure to check the customer reviews and return policies. Consider the battery condition, as older batteries degrade performance. Check the device’s grading (A, B, or C), where A indicates a nearly new condition and C signifies more wear. Avoid buying models that are too old (more than three generations old) to ensure continued iOS updates and app compatibility. Lastly, inspect the Liquid Contact Indicator (LCI) to determine if the device has suffered water damage. If the LCI is red, the phone has likely been exposed to water.
