I sold my iphone 11 pro max 152gb to Grade for a secured price of £750.11, posted it and then got an email to to say " the battery is below the recommended percentage and will need to be replaced and the screen has scratches present." and therefore they reduced price to £609 - nowhere on the grading scale does it mention the battery health and also i know the phone didn't have any scratches because it was in a case with a screen guard for it's life. it seems following the iphone 12 release they decided not to uphold the secured price and reduce in line with other buyers. also reading reviews it's the same tactic they've done with other customers scam artists. phone line is not in use and they diced to ignore my complaint
