Everything is 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 revealed, 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 “ iPhone battery may need servicing“, 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:

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 the slow speed of your iPhone is not related to the battery. The ultimate solution in in this case is
Many users, when studying in detail the characteristics of the gadget they like, first of all look at its technical component. But even detailed information about the device’s internals 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 determined. This is a very revealing process, because if the model gains a large number of points in a popular benchmark, then its value increases in the eyes of the average user, who may not understand anything about hardware at all.
How it works?
Synthetic performance tests have migrated to the mobile platform with personal computers. Since smartphones began to be massively equipped with a powerful computing component, there has been a need 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. Specific 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 Applications have appeared that provide the required iron load under specific conditions. Well, in essence, a benchmark is any process occurring under the same conditions on different hardware platforms.
The load on the processor, RAM or graphics chip does not have to be extreme, but to reliably estimate the power of the hardware, a rather heavy and resource-intensive process is launched within the acceptable norm. There is no need to worry: the filling will not burn, the back cover will not fry. All that is required from the user is to download the appropriate application and launch it on the device. For the purity of the experiment, it is better to close other applications.
Based on the results of tens and hundreds of smartphone tests, each benchmark application has its own database, where the results of synthetic tests passed by each device are stored. Based on them, unique performance ratings are compiled. Getting to the top position in such a ranking from a reputable benchmark for any modern device is very prestigious.
AnTuTu
The program tests the operation of the chipset, RAM, 2D and 3D graphics, the write and read speed of the drive, and the performance of database operations. Bonus features - battery test and OS stability test. As a result, you can see the performance of each component of your device separately, and also see overall assessment productivity.
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 a gadget scores based on the test results, the better.
Geekbench 3
– another popular cross-platform benchmark. The utility creates artificial but realistic loading conditions for the device's hardware platform to reveal the true performance capabilities.
A distinctive feature of the program is a processor test. The benchmark not only loads each chipset core individually, but also demonstrates real results in single-core and multi-core operating modes.
3DMark
The utility is known, perhaps, to all avid gamers. The program can simulate real gameplay on a PC, thereby allowing you to intelligently load the entire hardware of your computer and determine its real performance.
Having caught the trend in time, the software creators 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 available in total. The utility initiates loading of the central and graphic processors as close as possible to the real situation, and as a result makes its own verdict and offers to compare the results with other devices that have been tested.
For the correct choice of equipment, be it an antenna for a 3G modem or GSM repeater, we need to know the frequency and signal level.
To determine these parameters, absolutely every phone has hidden program called Netmonitor. For each phone model, this program is activated with its own individual code. For our iPhone, you need to enter a code in dialing mode *3001#12345#* and press the call button.
Choose UMTS Cell Environment -> Nightbor Cell(neighboring cells) -> UMTS Set-> after that you see a list of available channels. Channel 0 is the active one, on which this moment The phone is sitting.
Downlink Frequency 2938 - channel number by which the carrier frequency is determined.
2937-3088 , then this is 3G/UMTS900 - and we need a 900 antenna or a 900 repeater ***.
If the channel value is in the range 10562-10838 , then this is 3G/UMTS2000 - select a 3G antenna at 2000 MHz and a repeater at 2100 ***.
If the channel value is in the range 974-1024 , then this is GSM900 - we need antenna 900 and repeater RF-Link E900-***.
If the channel value is in the range 512-886 , then this is GSM1800 - select antenna 1800 and repeater 1800 ***.
You must understand that the phone displays all values only for the cellular operator whose SIM card is inserted into the phone at the time of measurement! And if you want to install equipment for two or more mobile operators, then you need to do all the measurements with each SIM card!
More different from the first iPad fast processor. And now we have two cores instead of one. The first generation used the Apple A4 chip, a Samsung-made analogue of the single-core Cortex A8 - a SoC (system on a chip) type model with an integrated PowerVR SGX 535 graphics core, 256 megabytes random access memory, operating at a frequency of 1 GHz. In the iPad 2, this is the Apple A5 chip, an analogue of the Cortex A9, also a highly integrated SoC-type chip, now with two computing cores, with a much more powerful PowerVR SGX 543MP2 graphics core and already 512 megabytes of integrated RAM. According to the specifications, the power consumption of the chip, despite the increase in the number of cores, remains the same.
SoC (system on chip) A5 in a tablet Apple iPad 2 - two cores, 1 GHz, integrated graphics, memory
The appearance of a new processor is very logical - advanced Android tablets already use dual-core Cortex A9 processors, and the appearance of the Apple A5 evens out the performance imbalance (which Android tablets have not yet taken advantage of).
A remark needs to be made here. Apple processor The A5 has become faster not only due to the second core - it also has higher performance per clock. That is, we have approximately the same situation as with processors Intel Core i7 on architecture Sandy Bridge, a review of which you can find in the “Processors” section - at the same frequency, the chip core works faster. The increase from 512 kilobytes to 1 megabyte of second-level cache also has a positive effect on performance. The chip is made more “thin” technological process, including this helped to maintain its energy efficiency.
And while it's quite accurate to say that the A5 processor is twice as fast as the old A4, those who read our processor reviews know that simply increasing the number of cores is not enough to get a speed boost. Developers must be able to use additional cores and make their applications multi-threaded. We compared how programs run on the first iPad and on the iPad 2 - yes, the increase is noticeable, but today you won’t see these “twice” with your eyes or touch them with your hands.

Due to the Apple A5 program on iPad 2 they start faster, navigation applications have softer and smoother scrolling, some subtle jerks and slowdowns have disappeared (which you notice when you perform the same task on two tablets at once). Frame rates have increased in games. There are even applications that provide an increased level of detail for the iPad 2. That is, on the one hand, the effect is obvious, but, to be honest, it is not as noticeable as you would expect when you hear about a processor that is twice as powerful.
Again, it's only a matter of time. Coupled with the multitasking of the current generation iOS new the processor will provide more effective work applications in parallel mode, as well as the emergence (in the future) of more resource-intensive, and therefore more functional, applications. Of course, games will be able to become more spectacular, and the dramatically increased performance of the graphics core will help with this. Let's say, the very next day after the start of sales of the iPad 2 we saw App Store gaming application Real Racing 2 HD with a note that it is optimized for iPad 2 and big amount negative comments from owners of the first iPad, complaining about “no” graphics.

Battery life has not changed, according to Apple. This is good in itself, but it sounds more impressive against the backdrop of increased performance and expanded functionality.
An interesting point is that the GeekBench benchmark shows a different processor frequency each time it is launched on the iPad 2. Based on its performance, some publications indicated that the processor frequency is iPad 2 about 900 MHz - with several consecutive launches we got a spread from 810 to 895 MHz. As far as we can understand, the frequency of the chip varies depending on the load, so it’s difficult to consider the GeekBench results in any way indicative. With each run, the test results also vary, and quite significantly. Here's what we got in one of the runs:

The performance and speed of the system greatly depends on the clock frequency of the processor. This indicator is not constant and may change slightly during computer operation. If desired, the processor can also be “overclocked,” thereby increasing the frequency.
You can find out the clock frequency as follows: using standard methods, and using third-party software (the latter gives a more accurate result).
It's worth remembering that clock frequency The processor speed is measured in hertz, but is usually specified in either megahertz (MHz) or gigahertz (GHz).
It is also worth remembering that if you use standard methods of checking frequency, you will not see such a word as “frequency” anywhere. You will most likely see the following (example) − "Intel Core i5-6400 3.2 GHz". Let's look at it in order:
- "Intel"- these are the names of the manufacturer. Instead there may be "AMD".
- "Core i5" is the name of the processor line. Instead, you may have written something completely different, however, this is not so important.
- "6400"— model of a specific processor. Yours may also differ.
- "3.2 GHz" is the frequency.
The frequency can be found in the documentation for the device. But the data there may differ slightly from the real ones, because... The documents say the average value. And if any manipulations were performed with the processor before, the data may differ dramatically, so it is recommended to obtain information only by software.
Method 1: AIDA64
AIDA64 is a functional program for working with computer components. The software is paid, but there is a demo period. In order to view data about the processor in real time, it will be quite enough. The interface has been completely translated into Russian.
The instructions look like this:
Method 2: CPU-Z
CPU-Z is a program with easy and clear interface, which allows you to view in more detail all the characteristics of the computer (including the processor). Distributed free of charge.
To see the frequency, just open the program and in the main window pay attention to the line "Specification". The name of the processor will be written there and at the very end the current frequency in GHz will be indicated.
Method 3: BIOS
If you have never seen the BIOS interface and do not know how to work there, then it is better to leave this method. The instructions look like this:
Method 4: Standard system tools
Most easy way of all, because does not require installation of additional software or entering BIOS. Find out the frequency standard means Windows:
Finding out the current frequency is very easy. IN modern processors this indicator is no longer the most important factor in terms of productivity.
