What to look for when buying a used iPhone

You've made the decision to buy a second-hand iPhone, and quite logically a bunch of questions arise that you don't have an answer to. You start looking for adequate and reliable information. In this article, we will guide you to a few important points that should not be missed.
What is your budget? – determine the amount you would spend on a second-hand phone. This will help you orient and focus in your choice.
What is the model and what will you use it for? – Answer the question of what you will primarily use the device for. You will take pictures or conduct communication. Let's take the iPhone 11 and 11 Pro as an example - the camera on the 11 Pro has greater capabilities and provides higher quality photos, while the iPhone 11 is more convenient for correspondence. And for those who like to watch a movie on their phone, there is the Pro Max series with a 6.5-inch display. Choose the one that suits your needs and preferences.
1. What is the reported state of the device?
If you have the opportunity, check for signs of use. Also test basic features like connection, camera, sound. In the absence of this prior information and if it turns out that the phone does not meet your criteria, it can always be returned if it was purchased from a reliable dealer.
2. Battery
It's important to note that by Apple's standards, a battery with 80% capacity is working and functioning properly. During its lifetime, the battery uses 80% of its capacity, so don't be alarmed when you see less than 90% capacity
3.Is there a warranty?
Check if the seller offers some form of warranty for the phone. Any reliable dealer of second-hand phones should provide a warranty on the functionality and quality of the handset and battery.
What components can be replaced and what notifications and standards are there for used smartphones?
For Apple models from iPhone XR and newer /11,12,13,14/, depending on the specific situation, you may see one of the following messages on the screen when we have a component replaced at a non-Apple authorized service center:
● Unable to Verify This iPhone Has a Genuine Apple Display" (Unable to verify that this iPhone has a genuine Apple display) - This message may appear if the original display of the iPhone 11 has been replaced with another one, as well as on the models produced after it.
● "Unable to Activate Face ID on This iPhone" (Unable to activate Face ID on this iPhone) - You will see this message when replacing the front camera module that is responsible for the functionality of Face ID
● "Warning: Unable to Verify This iPhone Has a Genuine Battery" (Warning: Unable to verify that this iPhone has an original battery) – If you replace the battery of iPhone XR, iPhone 11 or 12, 13, 14 with a new battery, whether original or not, it can
see this warning. More on iPhone display, battery, or camera replacement notifications can be found here.
The worry of buying a second-hand phone and having replaced components is unnecessary. Battery replacement for example, means the device has passed tests and its battery was not in good health, so it was replaced with a new one. The same goes for the display, which means you're buying technically sound devices, and significantly cheaper than new.
