Sell an iPhone with battery health under 80 percent

Yes, ReMint buys iPhones with battery health under 80 percent in the UK, and a low battery is one of the most common things we see. It might show as a Service or Important Battery Message note in Settings, or it might just be a phone that dies by mid afternoon and shuts down in the cold. As long as the phone powers on and everything else works, it is still a working phone in our eyes, and the battery is simply one of the questions the calculator asks. You will see the price before you decide whether to order.

First, find the real figure, because the number on the lock screen is the charge level, not the battery's condition. Go to Settings, then Battery, then Battery Health, and look for the line labelled Maximum Capacity. That percentage is the one that matters and the one our calculator asks about. Ignore the charge percentage at the top of the screen entirely.

On the calculator, choose your model and storage, then answer the battery health question with the Maximum Capacity figure you have just read. If the rest of the phone has no cracks, chips or faults, choose Working even with a Service message showing, since that message is a note about the battery, not a fault with the phone. If there is other damage, such as a cracked back or a faulty camera, choose the relevant damaged grade and answer the battery question as well. The price updates as you go.

An honest answer costs you nothing. When your phone arrives we read the real battery figure with our diagnostic software as part of the automated test, and we price the phone we receive. If your answers match what we find, the price you were quoted is the price you get, fixed for 10 days from the order. If they do not match, we send you a revised offer to accept or decline, and if you decline we return the phone free, so there is no advantage in guessing high and no penalty for telling us exactly what you see.

Everything else works as it does for any iPhone we buy. Turn off Find My iPhone and sign out of iCloud before posting (Settings, tap your name at the top, then Sign Out), because a locked phone is put on hold until it is released. Post it free with the prepaid Royal Mail label, or show the QR code at the Post Office if you have no printer. We check it within one working day of arrival and pay by bank transfer within 48 hours of it arriving, Monday to Friday.
