Due to the fairly high iPhone cost, and most importantly, in view a huge amount fakes, be sure to carefully check the device data before purchasing. Especially before purchasing it, it would be useful to find out the date and place of release of this iPhone. This alone will help ensure its originality. Because There have been cases when an old refurbished phone was inserted into the case of a new model, and outwardly it looked quite decent. A factory serial number and other codes are registered in the device’s memory and cannot be changed.

In light of the fact that with the release of the new iPhone 6S, many owners will sell their used “sixes” in order to buy a more advanced new product, this instruction you will definitely find it useful.

Looking for the serial number

IN in this case An analysis of the device’s serial number will be very informative, which will help you immediately discard dubious gadgets at the initial stage. It can be found on the original packaging of any iPhone, with reverse side– on a sticker with main characteristics and barcodes. Therefore, having a branded box is especially important when buying used iPhones. We are interested in the second row of numbers marked - Serial No. It contains encrypted data about the place of production (which specific plant), the production date (six months and weeks), information about the series and technical parameters, the personal code of this device.

However, there are cases where cunning dealers pack a fake or problematic iPhone (locked, broken, restored, stolen, locked, etc.) into the original box. So be sure to check the data on the package and those preinstalled in the phone itself. True, they can only be recognized by turning on the smartphone; if it is new and not configured, ask the seller to help activate it.

After that, go to settings. Select the section - General, and in it - the item “About the device”. If the data matches completely, great!

It is also important to find out the release and activation date of the iPhone to correctly calculate the validity period official guarantee. Especially if the previous owner activated it immediately, and the required year has already passed. You can check the remaining support period of the manufacturer in a special section on the Apple website.

Modern iPhone models have a twelve-digit code consisting of a combination of letters and numbers. When checking, please note that Apple never uses the letter O in serial numbers; it will most likely be the number zero. Otherwise, the search will give an error, although in fact everything is fine with the smartphone.

For example, let's see what this serial number of this iPhone tells us.

In the “About device” menu of the smartphone settings we find required code: F17NGDERG5MG. We are interested in the two letters in the middle: the fourth and fifth - F17 NG DERG5MG.

Let's use the special plates below to find out the production date. We look at the letter N in the first table - this is the code for the year of manufacture. It means that the device was manufactured in 2014, in the second half of the year.

Buy a used device - this is good way save money, since many people sell their phones and tablets almost immediately after purchase, but you still have to reduce the price, and at current prices for equipment from Apple, this will be a decent discount. But when buying a used device second-hand, there is one big risk - paying for a broken or non-original iPhone or tablet. To avoid falling for scammers, you need to check the device before purchasing and follow several rules, which will be discussed in the next part of the article.

How to check an iPhone when buying second-hand

If you decide to purchase an iPhone, iPad or iPad touch from hand, and not in an official store, then the first thing you should pay attention to is the seller himself. This is a weak indicator, but before you buy something from a person, see if he inspires trust. If this is a supplier that is engaged in mass resale of used devices, then read reviews about it, contact it former clients: Ask them if they are happy with their purchase, if the device broke some time after activation. But remember that many scammers fake reviews, which means not everything said about a seller on the Internet may be true.

If the issue is resolved with the seller, then the next thing worth checking is the device itself.

Appearance

Before buying, go to the official store and hold the desired device in your hands, study the tactile sensations of the material from which it is made. Find out the approximate prices at which you can buy original device, if its used version differs in price too much, then it’s worth considering.

Items required to test the device

So, if you are making a deal, then in order to be completely confident in the functionality of the device, you need to have the following things with you:

• Working headphones, you will need them in order to check whether they work with the device you are purchasing. Do not hesitate to ask the seller to give you the device for testing, this is a mandatory step. You can't buy a device without checking to see if it runs the programs you care about and activates certain features.
• A laptop on which iTunes will be installed, which will allow you to check many of the characteristics of the device. How to do this will be discussed below in the same article.
• An external battery that can be used to check whether the device is charging or not.
• A phone that has a stable Mobile Internet.
• SIM card - this is useful for checking cellular and Internet connections.
• A paper clip or special key, which comes with Apple devices. These items will be needed to remove the SIM card tray from the device body.

Having the above things, you can easily check the operation of all functions and applications of the purchased device. What parameters you will need to pay closer attention to will be described further.

How to distinguish the device model

If this is not your first time encountering Apple devices, you can skip this point. But if this is your first time buying equipment from Apple, then this information will be very useful for you. It's easy to distinguish an iPhone 5 from an iPhone 6, but it's a little more difficult to distinguish an iPhone 4 from an iPhone 4S.

The two models are distinguished by their model number, which can be found on the back cover when turning the device face down.

Also distinctive feature one model from another is appearance rear camera and home button. The iPhone 5 has a narrower camera, and the iPhone 5S has a square on the Home button, which indicates the presence Touch functions ID.

iPhone 6 and 6S

These two models are easier to distinguish - just wrap the device with the front side with the screen facing down, and on the back check for a diamond-shaped icon with English letter S.

Here the situation is similar to the iPhone 5, since you can check the device model using the code on the back of the case:

The device model can also be determined by the location of the antennas.

You can read more about all device models on the official Apple website by clicking on the following link - https://support.apple.com/ru-ru/HT201296.

Checking the water sensor

Before purchasing a device, you need to make sure that it has not been recessed. Water penetration into iPhone, iPad or iPod touch can lead to both instant failure and corrosion of the metal, which will lead to failure after a few weeks or months. Another important factor is the fact that a device exposed to water will automatically void the warranty.

Apple devices have a special external sensor - Liquid Contact Indicators, a humidity indicator. If water has ever gotten inside the device, this sensor changes color from gray or white to bright red. Read more about where this indicator is located at different models phone, is outlined in the table:

Equipment

Now let's look at what should be in the box, besides the phone itself:

All other accessories must be purchased separately. If one of the components of the package is not in the box upon sale, then this must be separately agreed with the seller and will affect the price of the product.

Authentication

The next step is to verify the authenticity of the device using the serial number and unique IMEI code. This data can be found on the back of the box, on a special sticker. But this data should not be trusted, since the box may be from another device or the sticker may be fake.

There is a more reliable way to find out this information - through the settings of your phone or tablet, where no one can falsify them.

1. We take the device in our hands and open the “Settings” application.
2. Let's move on to the "Basic" section.
3. Go to the “About this device” subsection.
4. Here you can find two lines: serial number and IMEI. You can check these numbers with those indicated on the box presented by the seller. If they do not match, it means that the device does not belong to the box, and this is a reason to think about the seller’s honesty.

Another way to find out the codes we need is to pull out the tray where the SIM card is located and read the serial number and IMEI indicated on it. You can remove the tray using a paper clip. This method has one drawback - not all device models have codes indicated on the tray.

The last way to find out the IMEI is to turn the back of the device and look at the small letters and numbers at the bottom of the cover, among which our treasured number is located.

As soon as you are done finding out the numbers and codes, you should go to one of the sites suggested below and enter the necessary data there. The site will show you detailed information about the device: color, release date, contents and filling, model number. Compare all the data with what you see on the device itself and with what the seller himself told you. If everything matches, then you can understand further.

Checking for recoveries

Checking for blocking

• Neverlock is a device without any restrictions in the field of operator choice.
• Softunlock is a device that previously belonged to the Lock group, but then was “unlocked” by software, that is, it now has all the parameters characteristic of Neverlock.

Screws

There should be two unscrewed screws near the USB cable input. If they are missing, then we can safely say that the device was disassembled manually and, accordingly, the warranty does not apply to it.

Buttons

Screen sensor

Move icons around your device menu, making sure they move smoothly. Try using the device in horizontal and vertical positions. If possible, quickly type the message on the keyboard, and all the letters you press should appear on the screen. If this does not happen, then the device has obvious problems with the sensor.

Battery

Start shooting a video and check how much the device shrinks in 2-3 minutes. A range of 1–5% is acceptable, all other parameters mean there is a problem, and no one wants to change the battery immediately after purchase.

cellular

Speaker

Everything is simple here - turn on any melody and check how well the device reproduces it. There should be no interference, no jumping, no rustling. You can also check the speaker during a telephone conversation.

Wi-Fi, Bluetooth

Check if these two functions work. Remember that Bluetooth only works with other Apple devices; it will not transfer files with Android. TO Wi-Fi networks the device should connect quickly and be able to download files through it.

Charger

For this item, you took a third-party battery with you. Connect it to your device and check if it charges.

Connecting to iTunes

If you happen to take your laptop with you, try syncing your device with iTunes. This will confirm its authenticity. You should not buy a phone or tablet that is not recognized in iTunes.

Sign out of your Apple ID account

The last thing you should do before handing over money for a device is to completely exit the account old Apple ID belonging to the previous owner. Otherwise, he can declare the device missing at any time and block it remotely, without asking your consent at all.

1. Open the Settings application.
2. Go to the iCloud section.
3. Turn off Find My iPhone.
4. Let the previous owner enter the password for his account, this is necessary to disable the function.

   So, before you give money, thoroughly check the device using the instructions described above. Be very careful, give money only for what you personally held in your hands and tested. Demand complete set or explanations why this or that thing is missing. The main thing is don’t forget to log out of your account. previous owner, since most scammers make money precisely on this oversight of buyers.
