When considering a used iPhone, prioritize purchases from trusted platforms like Amazon or certified refurbished vendors. Scams are common, and a thorough evaluation is necessary. Battery performance is a key concern. Certified refurbished iPhones often include a new battery and may have a warranty. Assess the phone’s condition using the grading system (A, B, C). A-graded phones are nearly new, whereas C-graded phones show more wear. Verify that the phone is not too old. iPhones that are more than three generations old may no longer receive iOS updates, leading to reduced functionality and security risks. Check for water damage using the Liquid Contact Indicator (LCI), usually located inside the SIM tray. If it’s red, the phone has been exposed to water.
