How to know if Apple is slowing down your iPhone. Using the CPU-Z utility

that the performance of some iPhone models decreases with wear battery. Users have found that clock frequency The processor can 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 decide 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, however, 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 the performance of the iPhone is a reduction in the nominal capacity of the battery by more than 20%. This happens after about 500 recharge cycles, that is, a year or two after buying a smartphone, depending on how often you use it and.

You can still get 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 capacity of the battery with the one that was originally. Usually Apple does not disclose which batteries are installed in its smartphones, but such information can be found on the network (for example, on).

Checking battery capacity

Such a tester can be bought for one and a half to two hundred rubles on AliExpress and other similar sites. Discharge the battery to zero, connect the smartphone to charging through it and leave it to charge up to 100%. The tester screen will show the amount of energy stored in the battery in milliamp-hours. Compare this value with what it is, and draw conclusions: if at least 20% less is left, the battery needs to be changed.

Using a Mac and the coconutBattery app

Connect iPhone to Mac with lightning cable. Download the application to your computer, install it and run it. Click on the iOS Device tab - you will see system information about the smartphone, including indicators of nominal and real battery capacity. Keep in mind that if you reset your smartphone to factory settings and restored it, the battery information could be lost, and the application will give out the real capacity for the nominal one.

With the Battery Life App

Download on iPhone free app and run it. It will show the degree of wear of the battery as a percentage.

IN system settings

Open the battery section in the smartphone's system settings. If the battery has less than 80% of the nominal capacity left, you will see a warning to contact the service center.

Performance check

Install CPU DasherX on your smartphone, run the application and see what clock speed the processor is running at. Apple only slows down a few recent iPhone models, their normal CPU frequency 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 level of charge - the lower it is, the less performance.

It would seem that not so long ago, the main topic of discussion among gamers were two eternal brand wars - against Radeon and AMD against Intel. The protracted battle has already lost its meaning, and fans of this or that brand simply cannot convince each other. Now gamers have another platform - mobile. And here there is a much wider variety of manufacturers, so it has become much more difficult to determine which processor is better for games.

And the point here is not even in the “stones” themselves, but in the fact that marketers first of all promote the brand. In advertising highlight the features of the interface, operating system, cameras and other elements of smartphones and tablets, and the brand of the processor and its performance are mentioned only in passing. In order not to mix everything together, let's deal with the types of CPU for. We will consider only the processors of Android devices, since there is no choice as such on the iOS market.

Most users do not distinguish between chipset, processor and SoC (system-on-chip). In fact, these are three different terms. A chipset is a set of microcircuits that enable the processor, memory and other electronics to work together. SoC is a multifunctional system built on a single chip. SoC includes not only the processor, whose performance is usually talked about, but additional processors responsible for processing audio, video, standard tasks, and so on.

For example, the Tegra 2 SoC chipset has 8 processors:

1. For video encoding;
2. For video decoding;
3. For image processing (for example, from a camera);
4. To work with sound;
5. Graphic;
6. For standard procedures;
7. and 8. For the main computing processes - two Cortex-A9.

Determining the number of cores of a particular chipset, they are talking about the main computing processors, and in our case there are two of them, that is, Tegra 2 is a dual-core processor.

Why are so many other data handlers installed in the SoC? To reduce the power consumption of the device. On this moment LTE modules are also built into the chipsets, which reduces battery consumption compared to previous solutions, when this communication module was installed separately.

Frequency, cores and performance

The vast majority of tablet buyers believe that the number of processor cores directly affects performance. In this view, an 8-core CPU is always in an advantageous position relative to two-, four-, and even more so single-core ones.

The situation is the same with the clock frequency: than more figure the better, say the owners portable devices. But this logic is not entirely correct, since performance depends on more factors.

For example, one of the important nuances of microchip architecture is the norm technological process processor manufacturing. In smartphones and tablets, 32 nm is now most often used. Roughly speaking, this is the thickness of the conductive paths that transmit signals from element to element. The smaller this value, the better, because the resistance will be lower. The 20 nm standard is just starting to gain momentum, but when it will become the main one is unknown.

We will not analyze all the details of the development of chipsets and the implementation of various technologies. The essence remains the same - games on a tablet with dual core processor may run more smoothly than on a device with four cores and a higher clock speed. There can be many reasons for this. Of course, this is not always the case, but we must understand: a large number of cores and a high frequency of their work is not a guarantee of success.

Software optimization

The most important thing for performance is the optimization of the firmware, the operating system itself and software. For example, we can take the iPad Air 2, which has a triple-core A8X processor with a clock speed of 1.5 GHz. When developing iOS 8 and the firmware of the device, Apple focused on the hardware of this tablet and on the processor, so its optimization is close to ideal. At the same time, you can take any Chinese tablet based on Qualcomm Snapdragon 800. This processor has four cores with a clock speed of 2.3 GHz.

If it were possible to compare both chipsets without using different operating systems and other components, Snapdragon would win a clear victory. But many factors end up giving us a very different picture. Air 2 delivers amazing performance and a smooth interface, and the latest high-end games run smoothly on your tablet. Maybe Apple A8X is best processor for a tablet?

In the case of Qualcomm Snapdragon 800, the situation may be different. The Chinese tablet Docomo F-02F has no particular problems with the interface, but they are still noticeable. Some game projects are doing just fine, while others do not give out high enough FPS. But Pro 8.4 based on the same chipset does not cause any complaints at all. As you understand, a direct answer in comparing two different processors not always possible to obtain.

Processor Software Testing

Often, when choosing a tablet or smartphone, people are guided by the performance of various tests, believing that the higher the number displayed in the result window, the better device they got it. In fact, there are many pitfalls here.

Browser testing

Sometimes in tablet reviews they arrange comparative tests of browsers different devices. If the devices are close in hardware and platform, then it makes sense. But the greater the difference between devices, the more useless these numbers are. At the moment the most fast browser considered as such in the Blackberry BB10 operating system, and all devices with this OS are developed on outdated processors. Fortunately, we are trying to determine which processor is best for games, and here the situation is much simpler than with browsers.

AnTuTu test

AnTuTu testing app is now the standard for tablet reviews. There is no such review where the indicators of competitors' tests were not used. And in this case, we advise you not to rely heavily on the accuracy of the data obtained.

The number that the application gives after testing shows the sum of the following results:

• memory performance;
• integrated processor performance;
• calculation of floating point numbers;
• 2D graphics performance;
• 3D graphics performance;
• SD card write and read speed;
• I/O performance.

Among them there are tests that have a direct meaning, such as calculating numbers. And there are those whose testimony can be called muddy. Trust, for example, performance indicators of 3D-graphics is not worth it. But we are considering the total amount, which means that we will not be able to get an exact answer.

If we compare the Note 4 ratings, Apple iPhone 6 Plus and Meizu MX4, it turns out that, despite the different software and hardware stuffing, their performance is on the same level. It is unlikely that all three devices behave in the same way in all cases. Everyone has their positive aspects, there are also disadvantages, but according to the results of the test, we will not know anything about this.

At the same time, the AnTuTu test tries to show what the device is capable of when maximum loads. The tablet chipset is designed in such a way that it does not work constantly at high power, because because of this it would be discharged in a few minutes. The clock speed of tablet processors varies depending on specific applications and their requirements. Let's say 2048 doesn't need the same performance as Modern Combat 4. But we can consider the test results as a reference figure, on the basis of which we will choose the best processor for the tablet. If we choose the CPU for just such purposes, then we are not interested in performance in the browser or in light arcade games.

AnTuTu scandal

Last year, it turned out that Samsung programmers were able to come up with a way to cheat performance testing apps. The devices of the Korean company understood which application was currently running and changed the clock frequency. So the performance of AnTuTu turned out to be too high. On the other hand, this is how most software works, so there was no significant cheating here, but still the company acted not entirely honestly.

Dependency on RAM

If volume random access memory will be limited, then no most powerful processor will not give you a comfortable level of FPS in games. Among gamers, the thought sometimes slips that too much RAM is an unnecessary luxury. This is partly true.

operating room android system capable of working with only three gigabytes of RAM. The restriction may soon be lifted, but this will not be such a significant event for gamers for the second reason.

Modern games do not require too many of these same gigabytes. Of course, for some projects one will not be enough, but two is enough. 3 GB can justify itself in one case out of a hundred. When games become so demanding that increased memory sizes become the standard for top-end smartphones, it is still difficult to predict.

Processor manufacturers

Qualcomm

Qualcomm is the market leader. The trust of users and tablet manufacturers has been quickly won with high-quality, powerful SoC chipsets and constant innovation. For example, the built-in LTE module first appeared with this brand. Of course, the hyped chips are more expensive than the rest.

MediaTek

The main competitor of the previous brand is MediaTek. Unlike the leader, this company is trying to produce chipsets at an affordable price. Although on initial stage development, the quality of the company's chips was not at the highest level, which still remains a stain on the manufacturer's image.

Samsung

Korean manufacturer of tablets and Samsung smartphones tries to use only his own developments in his devices. Exynos chipsets do not lag behind the leader and its competitors, but have not yet gained popularity, mainly due to the use of processors on tablets of the same brand.

nVidia

Tegra processors from nVidia are still trying to find their niche and win over fans. For PC gamers who buy a tablet, such names sound more solid than the incomprehensible words Snapdragon or Exynos. The difference between Tegra is that the company itself is engaged in optimizing the most powerful and popular games, increasing the performance of some projects on its hardware.

Intel

Processors Intel Atom are only gaining popularity in the mobile market and have already achieved good results. They are distributed mainly under special conditions, so they often become the basis of Lenovo devices.

Conclusion

So, we decided that it is very difficult to choose the best processor for it, since everything depends on the operating system, the installed shell, the firmware version, the amount of RAM and other factors. Nevertheless, we found out that the top processors from Qualcomm and MediaTek are the leaders. But it is always difficult to choose, as new hardware solutions appear very quickly, and if you do not want to change the device once a year, then you will have to consider competitors very carefully.

But the best processor for a tablet at the moment is the MediaTek MT8392. The 8 cores at 1.7GHz are highly optimized and provide not only amazing performance, but also low power consumption: the cores are disabled when power is not needed, and the clock speed is also reduced. In addition, the developers of Modern Combat 5 have updated their game, providing improved graphics and high FPS for the new powerful chipset.

Back in the early 2000s, me and all my friends built computers on their own. After switching to laptops, tablets, gaming consoles in 2010, I forgot that feeling when you read the price list of companies that sell components and you know all the details in it. Then, with my eyes closed, I could choose the right processor, graphics card, RAM, case, and so on.

After buying or upgrading the assembled “monster”, the mandatory program included checking it through the 3D Mark performance test. After receiving the result, it was possible to roughly understand what games the computer would pull and how much it was superior or inferior to your friend's computer.

Measuring the performance of an iPad, iPhone, or iPod is pretty pointless. These are devices with predetermined characteristics. It is enough to look at some graph, which shows a dozen modern models of iDevices and see the place of your device in the hierarchy of Apple gadgets. Perhaps it makes some sense to compare with Android tablets, and even then - these numbers will not say much to most users.

However, in App Store there are apps that will test your iPad, iPhone or iPod for performance.

Geekbench 3

An application that, after short tests, gives a performance figure.

The program tests show two values:

• Single-Core Score - single core performance
• Multi-Core Score - performance when running multiple cores (in the case of the iPad Air, iPad Mini 2, 3, iPad Pro- these are two cores, iPad Air 2 has 3 cores)

For comparison, there is a special table. From which it follows that the iPad Air is more than twice as inferior to the iPad Pro.

Graphic test comes from China. The application shows special 3D clips that slow down on the iPad Air, and then gives out a figure that has nothing to compare with. So I got the figure - 66282. And you?

There is a slightly more extended layout for individual categories of tests.

The third test also shows 3D clips specially created to "humiliate" your device. On the iPad Air, the brakes are again ... From below, even in live statistics are given from which you can find out that my tablet pulls some videos at a speed of 4 frames per second.

Well, what kind of unoptimized engine is used to display generally simple effects?

As a result, the iPad Air on iOS 10 scored 1236 points in the Sling Shot test. And the Sling Shot Extreme test did not pull at all - it crashes.

From a special table that shows the average values, it can be seen that the iPad Air is located between the iPad Mini 2.3 and iPod Touch 6th generation.

I am skeptical about all these tests. Yes, they help to imagine how powerful this or that gadget is, but in general it doesn’t change anything. I will quickly run to the store for new iPad not because of test results, but if the current model ceases to suit me in terms of speed or if new demanding games stop running.

But so far, nothing extraordinary has been released in the App Store... For example, games like XCom 2 or GTA 5 for the iPad are not in sight in the future.

Many users, studying in detail the characteristics of the gadget they like, first of all look at its technical component. But even detailed information about the stuffing of the device will not give a clear understanding of how the device will behave in practice.

That is why, as noted, synthetic performance tests have become so popular, during which the real power of a particular device is found out. This is a very revealing process, because if a model scores a large number of points in a popular benchmark, then its value increases in the eyes of an ordinary user, who may not understand anything about hardware at all.

How it works?

Synthetic performance tests migrated to the mobile platform with personal computers. Since smartphones have been massively equipped with a powerful computing component, it has become necessary to compare different models.

The models are different, but they need to create the same testing conditions for the sake of the purity and reliability of the experiments. Defined test time, clearly marked load on each component: video accelerator, system memory, processor. By analogy with PC software (CPU-Z, GPU-Z, 3DMark) for mobile devices their own applications have appeared that provide the required loading of iron in specific conditions. Well, in essence, a benchmark is any process that occurs under the same conditions on different hardware platforms.

The load on the processor, RAM or graphics chip does not have to be extreme, but for a reliable assessment of the power of the hardware, a rather heavy and resource-intensive process is launched within the framework of allowable rate. You should not worry: the filling will not burn, back cover won't fry. All that is required from the user is to download the appropriate application and run it on the device. For the purity of the experiment, it is better to close other applications.

Based on the results of dozens and hundreds of tests of smartphones, each benchmark application has its own database, where the results of synthetic tests passed by each device are stored. On their basis, peculiar performance ratings are compiled. Get to the top position in such a rating from a reputable benchmark for any modern device very prestigious.

AnTuTu

The program tests the operation of the chipset, RAM, 2D and 3D graphics, the speed of writing and reading the drive, the speed of operations with databases. Bonus features - a test of the battery and the stability of the OS. As a result, you can see the performance of each component of your device separately, as well as see the overall performance rating.

By comparing the received data with its own extensive database of results, AnTuTu will place the device in its rating among other devices. Of course, the more virtual points the gadget scored according to the test results, the better.

Geekbench 3

is another popular cross-platform benchmark. The utility creates artificial but realistic loading conditions for the device's hardware platform to reveal true performance capabilities.

A distinctive feature of the program is the processor test. The benchmark not only loads each core of the chipset separately, but also demonstrates real results in single-core and multi-core modes.

3DMark

The utility is known, perhaps, to all avid gamers. The program is able to simulate real gameplay on a PC, thereby allowing you to correctly load the entire filling of the computer and determine its real performance.

Having caught the trend in time, the creators of the software released mobile version of its development. Depending on the component being tested and the class to which your device belongs, 3DMark will offer to download and install the appropriate test, there are seven of them in total. The utility initiates the loading of the central and GPU, and as a result makes its own verdict and offers to compare the results with other devices that have passed the test.

I think it is no longer a secret that Apple reduces the operating frequency of processors in its smartphones due to severe battery wear. This fact has long been users, and recently Apple has officially confirmed it. But is it possible to find out exactly your iPhone is slowed down and is it time to think about replacing the battery? In this article I will talk about how to check it in a couple of minutes.

How to quickly find out if Apple is slowing down your iPhone

To check if your iPhone's processor is slow or not, you need to go to " Settings» — « Battery". If at the very top of the screen there is an inscription " iPhone battery may need service”, then this means the frequency of the processor of your iPhone is reduced. In order to bring it to its original value, you will have to replace the battery in your smartphone. If you did not find such an inscription, then this means that the processor in the iPhone is running at maximum frequency.

like this elementary way You can check if your iPhone is slow. However, there is another way to verify this. To do this, do a performance test in the benchmark and compare the scores with the average of 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 Plus - 1436
• iPhone 6-1394
• iPhone 5s - 1268
• iPhone 5-754
• iPhone 5c - 743
• iPhone 4s - 284

Multi-core mode

• iPhone 8 Plus - 10169
• iPhone 8-10111
• iPhone X-10108
• iPhone 7 Plus - 5763
• iPhone 7-5739
• iPhone 6s Plus - 4157
• iPhone SE-4154
• iPhone 6s-3888
• iPhone 6 Plus - 2423
• iPhone 6-2355
• iPhone 5s-2140
• iPhone 5-1203
• iPhone 5s - 1186
• iPhone 4s-490

Also, you can always use the utility, which shows the exact current frequency of the iPhone processor.

There is no inscription, but the iPhone works too much - what to do

If the menu "Settings" → "Battery" there is no warning from iOS, then the slow speed of your iPhone is not related to the state of the battery. In this situation, restoring it to the last one can help. backup to be done just before the reset.
