Checking iPhone by IMEI. How to check the battery status and processor speed in an iPhone A program to determine iPhone hardware

Greetings! There can be a lot of reasons for the need to check information about how much capacity is left in the battery of an iPhone or iPad. Such a need may arise out of simple curiosity: for example, I was wondering whether I need to go change the battery on my old iPhone 5S? Or is she not so bad yet?

Also, great value A similar procedure occurs when purchasing a used device. After all, the seller can simply deceive - say that his battery holds exactly that much. And even show usage statistics (you can easily screw it up), but in fact, half of the capacity has already been lost. How to find out the truth about the condition of the battery - is it bad or not? No one will wait several hours for a check! There are easier and faster ways - let's talk about them, let's go!

Important note. We receive all data about the battery free of charge, without hacking the device or other jailbreaking. Cool? Wrong word!

Now we're definitely starting. Forward!:)

How to check the battery life of an iPhone or iPad using a computer?

There are a lot of programs that can give us all necessary information about the battery. These include the famous iTools, iFunBox and many others. However, they are loaded with various functions (sometimes very unnecessary), but we only need battery statistics! Therefore, in in this case, I recommend using iBackupBot - the function you are looking for is also not the main one, however minimum size program and simple interface speaks in its favor.

You can download it from the developer’s website; there are versions for Windows and Mac OS. Please note that iTunes installation is required to use the program.

Since all the inscriptions on English, I will give a short transcript of the received data:

• CycleCount – the number of complete battery recharges.
• DesignCapacity is the capacity that the new gadget originally had.
• FullChargeCapacity – current capacity.
• Status: Success – general characteristics batteries at the moment.

As you can see, in 2.5 years the capacity of my iPhone 5S has dropped by only 150 mAh and this is a very good result! In fact, it's almost new. How did he manage to achieve such indicators? I just know how to do it, try it too – there’s nothing complicated there.

Applications that tell you everything about the battery status of your iPhone or iPad

Unfortunately, no one is immune from the situation when a computer is not at hand, and you need to check the battery life of your iOS device here and now. Various applications from App Store. The best part is that you don’t need to hack your device or install a jailbreak – everything happens without it.

While writing this article, a huge number of programs (about 15-20) were installed on my iPhone in one way or another related to the battery. And only in one of them all data (charge cycles, actual capacity, etc.) were shown for free, immediately after installation and without any additional purchases.

Meet Battery Life. Download link in the App Store. Install and launch. Click on the left top corner– the settings open, we are interested in the menu item – Raw Data. And we clearly see all the information (also displayed in real time!).

A few points:

• Battery Charge - the indicator shows how much the battery is currently charged and how much it can charge maximum.
• Capacity – current\standard battery capacity.
• Cycles – number of recharge cycles.

The attentive reader will notice that the data for my device is slightly different when various checks(using a computer and an application). How so?!

Firstly, this difference is really small - an error of 3-5%. And secondly, this is completely normal - since different programs use different algorithms. And besides, the battery of my iPhone 5S has been working for quite a long time - almost 2.5 years, and it is quite difficult to analyze its use over such a period.

In any case, the check can be carried out using any option presented in the article, and the overall picture of the battery life of your iPhone or iPad will be clear. To get the most plausible values, use both methods and choose the average of what you get.

That the performance of some iPhone models decreases due to wear and tear battery. Users found that clock frequency the processor may drop several times, and all in order to maintain autonomy at the same level and prevent an emergency reboot or shutdown. A week later, Apple had to figure out what measures would be taken: it is useless to fight natural chemical processes, due to which the ability of batteries to accumulate energy after each recharge cycle drops slightly, but in 2018 the cost of out-of-warranty battery replacement in the iPhone will be reduced, and a utility will appear in iOS , which will let you know if it’s time to take the device in for repair.

Critical to iPhone performance is reducing the nominal battery capacity by more than 20%. This happens after about 500 recharge cycles, that is, a year or two after purchasing the smartphone, depending on how often you use it and.

It is still possible to obtain information about the health of the battery and the speed of the processor, but this requires third-party solutions. First you need to compare the actual battery capacity with what it was originally. Apple usually does not disclose what batteries are installed in its smartphones, but such information can be found online (for example, on).

Checking battery capacity

You can buy such a tester for one and a half to two hundred rubles on AliExpress and other similar sites. Drain the battery to zero, connect your smartphone to the charger through it and leave it to charge to 100%. The tester screen will show the amount of energy accumulated by the battery in milliamp-hours. Compare this value with what it is, and draw conclusions: if there is at least 20% less left, the battery needs to be changed.

WITH using Mac and coconutBattery apps

Connect your iPhone to your Mac using a Lightning cable. Download the application to your computer, install it and launch it. Click on the iOS Device tab - you will see system information about the smartphone, including the nominal and actual battery capacity. Keep in mind that if you reset your smartphone to factory settings and restored it, the battery information might be lost, and the application will misrepresent the actual capacity as the nominal one.

Using the Battery Life app

Download at iPhone free application and launch it. It will show the degree of battery wear as a percentage.

IN system settings

Open the battery section in your smartphone's system settings. If the battery has less than 80% of its rated capacity remaining, you will see a warning that you should contact your service center.

Performance check

Install CPU DasherX on your smartphone, launch the application and see what clock speed the processor operates at. Apple only slows down the last few iPhone models, their normal processor speed is:

• iPhone SE - 1800 MHz
• iPhone 6 - 1400 MHz
• iPhone 6 Plus - 1400 MHz
• iPhone 6s - 1800 MHz
• iPhone 6s Plus - 1800 MHz
• iPhone 7 - 2340 MHz
• iPhone 7 Plus - 2340 MHz

Keep in mind that the maximum clock speed may vary depending on the charge level - the lower it is, the lower the performance.

It's very simple.

Many iPhone owners We have heard that the processor frequency Apple smartphones may be reduced due to the condition of the device's battery. Apple is official confirmed this iPhone feature and how it turned out, there was no secret in this function. How do you know if your iPhone is slow and if it's time to change the battery? This instruction tells you how to do this in just a few seconds.

In order to find out whether your iPhone’s processor is slow or not, just go to the “ Settings» → « Battery" If at the very top of the page it says “ Your iPhone battery may need service“, this means the processor frequency of your smartphone is reduced and to restore it you need to change the battery. If this inscription is not present, then your iPhone is running at maximum performance.

This is how easy the check is to perform. However, you can additionally make sure that your iPhone is slowed down or, conversely, is working at full capacity. Run a benchmark performance test Geekbench 4 and compare your scores with the average for your iPhone model:

Single core mode

• iPhone 8 - 4216
• iPhone 8 Plus - 4216
• iPhone X - 4204
• iPhone 7 Plus - 3438
• iPhone 7 - 3426
• iPhone 6s Plus - 2427
• iPhone SE - 2418
• iPhone 6s - 2267

• iPhone 6 - 2355
• iPhone 5s - 2140
• iPhone 5 - 1203
• iPhone 5c - 1186
• iPhone 4s - 490

In addition, you can use the utility CPU DasherX, which shows the exact current processor frequency of the iPhone.

There is no inscription, but the iPhone is working terribly - what to do

If there is no warning from iOS in the “Settings” → “Battery” menu, then slow speed Your iPhone's performance is not related to the battery. The ultimate solution in this case is

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, 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 its former clients: ask them if they were satisfied 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 an 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 a special key that 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 the model number, which can be found on back cover, turning the device screen side down.

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

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 the presence of 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 back side housings:

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. If water gets inside your iPhone, iPad, or iPod touch, it can either break down every second or corrode the metal, leading to failure weeks or months later. 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 code IMEI. 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 are more the right way find out this information through the settings of your phone or tablet, no one can falsify them there.

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. List of sites providing similar services for providing information about Apple devices:

Checking for recoveries

Checking for blocking

There are three types of Apple mobile devices:

• Lock - phones that only work with one pre-defined carrier. That is, if you purchase such a device, you will be able to use the services of only one company that provides cellular communication and mobile Internet, and no other.
• 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” programmatically, that is, it now has all the parameters characteristic of Neverlock.

Of course, Lock devices are a little cheaper than Neverlock, but this saving will not lead to anything good, and there will be quite a lot of problems with a predefined operator, without the right to change it.

How to identify an unlocked device?

There are several characteristic signs that help to identify a device that was unlocked software:

Functional and physical testing

Now there is the last, but practically the most important stage - checking the standard capabilities of the device and its appearance.

Frame

Check if there are any noticeable dents, cracks, or broken pieces on the case. All of these parameters can tell you how often the device has been dropped and subjected to other physical impacts. Particularly dangerous are damage to the antenna area, which can lead to communication interference.

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

Check how well all the buttons perform their functions, since replacing buttons in the service can require a lot of money.

Camera

Check for external damage on the front and rear camera. Try to photograph something with both cameras. If you notice inaccurate colors, the camera sensor may be damaged.

Screen

Open various applications, restart your device, check for dead pixels(black dots). If when you press the screen there is a crunch, or you feel unevenness or emptiness, then the screen is not original, it has been replaced. Pay attention to the uniformity of brightness and color reproduction.

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 connection

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 paying money for a device is to completely exit 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 a complete set or an explanation of why this or that item is missing. The main thing is to remember to log out of the previous owner’s account, since most scammers make money from this oversight of buyers.

Check the functionality of all components of the iPhone, iPad or iPod Touch using the tools built into iOS is almost impossible - Apple technology can tell you about IMEI, serial numbers, versions operating system or data associated with Wi-Fi and cellular modules.

But, if for some reason the screen is acting up, the GPS has stopped giving the exact location, and the sound hisses and breaks the speakers, then you will have to turn to the App Store - a digital store for iOS, where you can find special programs carrying out comprehensive or partial diagnostics of parts of a smartphone, tablet or player.

TestM

A multifunctional working platform for iPhone, capable of replacing both a service center with professional technicians and other utilities available in the Apple store. And the main feature of TestM is its comprehensive approach. Sound, screen, touch calibration, storage, camera - in just 5-10 minutes the result of the completed diagnostics will appear on the display.

If there are green checkmarks everywhere, but the problem is not solved, then most likely it’s time to contact a service center. If red ticks appear somewhere, then you will have to deal with the problem in several steps. Problems with internal storage? You will have to carry out copying and deleting operations. Are the photos blurry? So, it's time to calibrate the front camera.

Overall, TestM is an excellent diagnostic program that can either tell you where to look for the problem or help with further actions(the developers from Checkee always leave hints and give a verdict - they say, it’s time to ask for help or it’s quite possible to fix problems in a semi-automatic mode).

The platform is distributed free of charge, without advertising and in-app purchases, and takes up a minimum free space. Even the Russian language is included. Perhaps you cannot find a better assistant in the App Store!

AIDA64

Information and reference center for diagnostics, telling about Apple technology in two ways. And from the point of view of a technical tool listing iPhone specs, iPad or iPod Touch (view graphics accelerator, processor type, display size, number of pixels per inch), and in the format of a diagnostic center that can check the performance of the sensor and screen, battery and RAM, camera and Wi-Fi.

Testing is carried out, although superficially, but some important information is still displayed - for example, how worn out the battery is, whether the screen is damaged, whether the load on the processor is correctly distributed and what maximum speed can be reached through the selected wireless point.

The AIDA64 center is available for free - the developers from FinalWire are even skeptical about advertising.

Geekbench 4

An iPhone diagnostic tool that conducts impartial performance tests on smartphones and tablets by processing various requests by the processor and RAM. Formally, the Geekbench 4 program is difficult to classify as a diagnostic tool, but in fact, developers from Primate Labs help to find out whether the smartphone can cope with the load as well as other models in the series or whether there are some problems with performance.

For checking, special tables are provided with results that change in real time and are suitable for certain iOS versions(for example, for version 12 the results are slightly better than for version 11 due to the optimization carried out by the developers).

The only problem with Geekbench is paid distribution. Even though 70 rubles is not too much for such a test, most likely you won’t want to test your performance a second or third time.
