Activation lock is therefore first unlocked through the vendor. To remove the iPhone activation lock go to the ‘Settings’ page and remove the activation lock from [Owner’s Name] > Find My iPhone.

Check and then erase iPhone

The seller can give you the phone by first erasing his iPhone and giving him a factory reset. This is a good thing, but this way there is no opportunity to test the iPhone first. Because in this condition you will come to the setup screen only when you turn on the iPhone. As a result, everything inside the iPhone cannot be checked unless the entire setup is done.

So the best way is to first ask the seller to test the iPhone without erasing it. You enter the phone with the seller’s information and check that everything is working properly. Then ask the seller to erase the iPhone when satisfied.

To erase, go to Settings > General > Transfer or Reset iPhone to Erase All Content and Settings option. However, during this time, the activation lock must be closed by logging in from the seller’s Apple ID. Then log out from the seller’s Apple ID. Then it will be better to erase.

Testing the entire phone from the outside

Battery health

iPhone battery health is one of the most important considerations when buying a used iPhone. The lithium ion batteries used in iPhones degrade over time and may lose their ability to hold a charge.

You can see the battery health of any iPhone by going to Settings > Battery > Battery Health. Generally, if the battery health is more than 80 percent, it can be assumed that the iPhone can provide good backup. If you buy an iPhone with a battery health below this, you won’t get a very good charge backup and performance may also suffer. Also, check if the iPhone shows “Peak Performance Capability” in the battery health section. Because if it shows anything else, it can be understood that there will be a performance problem due to the battery in that iPhone. If this is the case, it is necessary to change the battery of the iPhone.

Whether it’s a parts replacement or a refurbished iPhone

A refurbished iPhone refers to an iPhone that is being repaired and resold due to a problem. Sometimes Apple itself provides such iPhones. You can check this by going to Settings > General > About section and finding “Model Number”. Here, if the model number starts with F, it is a refurbished iPhone by Apple. This is not a bad thing, but good to know. However, there is no easy way to tell if a third party is selling an old iPhone for repair.

If it has been replaced and replaced by Apple itself, it will show as a genuine part, and if it is a third party part, you will see Unknown. However, this method may not work for all parts.

If you don’t see this list, either the iPhone parts have not been replaced or the iPhone is running on a version below iOS 15.2. So check this important thing before buying a used iPhone. A fixed iPhone will definitely cost less.


It is very important to check the display of the used iPhone. If it’s an iPhone with an LCD screen (iPhone XR, SE, 11 ,12,13,14), check for small blackspots on the LCD panel. And in the case of iPhones with OLED panels, check whether there is any burn-in on the display. Normally there is no way to understand the burn in on the display. For this you need to bring something of one color and then test it in the dark. Burn in refers to leaving a shadow of the previous content on the display. So buy the device only after checking these things well.
