Before buying a second-hand iPhone, be sure to check these 5 things, otherwise you will suffer a huge loss..

Thousands of offers for second-hand iPhones are available online, but many of these are scams. Always rely on trusted websites like Amazon, Best Buy, or Apple-certified refurbished products. Be sure to read customer reviews and return policies before purchasing, and be wary of overly cheap offers.

Most second-hand iPhones come with old batteries, which can lead to poor phone performance. Apple-certified refurbished iPhones come with a new battery and outer cover, and offer a 1-year or 6-month warranty. However, for other sellers, this varies depending on their policies. Therefore, be sure to check the battery health before purchasing.

Every e-commerce platform uses a grading system (A, B, C) to indicate the condition of second-hand phones. An A grade means the phone is almost like new, while a C grade phone may have more wear and tear. Therefore, read the grading carefully and make informed decisions accordingly to ensure you get the best deal.

When buying an iPhone, make sure it's not an overly old model. Generally, avoid buying an iPhone older than three generations. iPhones that are five or six years old stop receiving iOS updates, which can cause apps and security features to no longer work. Your experience on such devices can be degraded.

The iPhone has a Liquid Contact Indicator (LCI) to detect water damage, usually located inside the SIM tray. If it glows red, it means the phone has been submerged in water. However, if it's white or silver, the phone is safe. This is crucial to check before purchasing.
