Tech Regrade

Heavy wear and tear include heavy scratches, damage to the device’s case and any chips or dents. There are all kinds of reasons it can occur, including drops, bumps or even keeping your phone in the same pocket as your keys!

Screen burn commonly appears as yellow or orange lines on each side of the screen or permanently visible keyboard or app icons (also known as ghost images). It usually occurs on screens switched to full brightness and left on for prolonged periods.

Liquid damage is occasionally visible as bright white spots, dots or lines on the screen. However, sometimes the only way to tell is by inspecting the internal liquid damage indicators. It typically occurs when your phone is exposed to moisture. This can be anything from full submersion in water to steam from the shower!

The capacity of a battery reduces naturally over time, although we consider anything under 80% of its original capacity to be in low health. To test the capacity of a battery, we connect it to a computer and use the coconutBattery app. Low battery health is typically caused by charging your phone too much or incorrectly.

This fault refers to the screen lifting away from the device, leading to a visible gap. There are a couple of potential causes, including the battery expanding, the case bending or damage to the glue that holds the screen to the case.

Occasionally, a device’s battery can expand beyond its casing. This can cause major damage to the device’s casing and screen. This occurs when the battery has overheated, overcharged or is just generally faulty. It can also occur if the battery is old.

This refers to any internal damage to a device’s screen, including dead pixels, lines across the display, a blurry screen or a cracked LCD under the device’s glass. Some of these faults can occur naturally over a device’s life, although they can be caused by impact (i.e. dropping your phone) too.

When you sell your phone, you’re asked to specify which network the phone is on (if any). If our quality assessment team finds that your phone is on a different network (or locked to one if you chose ‘unlocked’), we will let you know and may revise your offer price.
