4s specifications

Back in 2011, the iPhone 4S smartphone went on sale. Its characteristics at that time were among the best, but now it is no longer a premium device. Nevertheless, its hardware and software components make it easy to solve most of the tasks that are relevant today.

The hardware basis of the smartphone

The computing basis of the smartphone is a 2-core chip "A5". The clock frequency of each of them is 800 MHz. If such a CPU were installed on a device running Android, then it would obviously not be enough for comfortable work. But after all, Apple devices operate under iOS, and this chip is enough for the normal and smooth operation of the system. Of course, the latest innovations of this platform on this smartphone will not be fully felt, but for most everyday tasks it is quite enough. This is watching movies, and listening to music, and reading books - he can handle all this without any problems.

Screen, cameras and graphics

The iPhone 4S has a rather modest display by today's standards. Its characteristics are really not impressive. The display is based on a high-quality IPS-matrix, the resolution of which is 640 by 960. Its diagonal is 3.5 inches. The image on the screen is not grainy, the quality of the picture does not cause any complaints. But working on such a small display is not very convenient. There are two cameras on this gadget at once. The main one is based on an 8 megapixel sensor, which is reinforced with additional optical elements. As a result, the photo quality is simply impeccable. The situation is similar with videos that are recorded on this device in HD quality. based on a 0.3 megapixel sensor. It is quite enough for making video calls. The connecting link of the graphics subsystem is the PowerVR SGX543MP2 video accelerator.

Memory

The memory subsystem in iPhone 4S is interestingly organized. The characteristics of each smartphone of this model can vary significantly. Each device can have a different amount of integrated memory, and its volume varies as follows: 8 GB, 16 GB, 32 GB and 64 GB. The larger the capacity of the built-in drive, the more expensive the cost of the gadget, but at the same time the device is more functional. Much easier is the situation with RAM (Random Access Memory), the capacity of which in any case in "4S" is 512 MB. The only thing that causes complaints is the lack of a slot for installing an external drive. But this is already a “disease” not only for this model, but for all devices that run iOS.

Body and ergonomics

Unusual appearance of the iPhone 4S smartphone. Characteristics, instructions and user reviews indicate that aluminum and glass are combined in the device case. It is this decision of American engineers that distinguishes the gadget from competitors. In fact, it has no analogues. The side faces are made of aluminum, and the front and back covers are made of glass. Moreover, the entire front of the gadget is covered with shock-resistant Gorilla Eye glass. Otherwise, it's the same iPhone 4 of the previous generation, but with a more powerful CPU and an improved camera. At the same time, as noted earlier, the diagonal of the display is 3.5 inches, which means that it is not difficult to manage it with one hand.

Battery

The nominal capacity of the battery in this smartphone is 1432 mAh. It is integrated into iPhone 4S. The description, characteristics and reviews of the owners of the gadget indicate that its one charge is enough for 2-3 days with an average level of use. But if the phone is operated to the maximum, then you can count on 1 day of battery life. On the one hand, the build quality of the smartphone raises no objections. But if the battery fails, then it will be problematic to replace it yourself.

Soft

As noted earlier, iOS on the iPhone 4S device acts as system software. Characteristics, reviews indicate that this is a well-run system, the functioning of which does not cause any complaints. It immediately has everything you need to work. If something was not included in the basic package, then the necessary software can be easily installed from the Apple application store, and you can even find free programs.

Communications

The iPhone 4S has an impressive set of interfaces. Characteristics, reviews of gadget owners highlight such of them:

1. Full support for all networks mobile communications 2nd and 3rd generation.
2. Built-in CDMA communication module.
3. Wi-Fi allows you to transfer information at speeds up to 150 Mbps when connected to the Internet.
4. For sharing small files, as well as for connecting wireless headset bluetooth can be used.
5. Wired port for connecting to a PC and for charging the battery.
6. 3.5 mm audio port for connecting a wired stereo headset to a smartphone.
7. It is also integrated into the ZHPS transmitter device, which allows you to easily turn this device into a full-fledged navigator.

The only thing that causes the lack of support for 4th generation networks. But at the time the device was released, they were still on and it was not entirely advisable to install such a radio module at that time.

We evaluate the intelligent assistant Siri, performance and updated camera

Last Thursday, October 13, sales of the new iPhone 4S began. As always, with the usual attributes in the form of queues in front of Apple stores and TV reports about the first lucky ones who became the owners of the coveted "apple" smartphone. On October 10, Apple reported that the number of pre-orders for the iPhone 4S exceeded one million in the first day (for the iPhone 4, this figure was 600,000). And this was clear evidence that consumer loyalty to Apple is such that the public is even ready to forgive the postponement of the expected announcement of the iPhone 5 and buy an improved version of last year's novelty instead. But how much improved? Today we have the opportunity to look into this in detail.

For starters, let's look at specifications. You can see a detailed list of them, but in the article we will give only the most important characteristics, as well as what distinguishes the iPhone 4S from the iPhone 4.

Speaking of new iPhone features 4S, Apple is a little cunning, adding to them the capabilities of the operating iOS systems 5. We consider this cunning because iOS 5 can be installed for free on iPhone 4 and even on 3GS, as well as on the last two generations iPod touch. In the near future we will prepare a separate article, where we will talk in detail about the new features of iOS 5. For now, we will focus on the unique features of the iPhone 4S and its differences from the previous model.

Equipment, design and screen

The iPhone 4S comes in a box that is almost identical in appearance to the packaging of the iPhone 4. The only evidence that this is a new model is the letter S in a silver square (on the left and right sides of the box), as well as the iCloud icon on the bottom (front) side.

Inside the box, everything is familiar and predictable: headphones, a cable for connecting to a computer, a charger (note that if you buy an iPhone abroad or from "gray" suppliers, you will have to buy a plug adapter). Two booklets, located in a white envelope, contain a minimum of information and will be useful only for beginners, but a metal clip is useful for installing a SIM card. Like last year's model, MicroSIM is used here.

As for the appearance of the iPhone itself, it has remained virtually unchanged compared to last year. Unless, the location of some elements on the side metal edging has slightly changed (for example, the mute button is now a few millimeters lower). But this indicates rather a change in the location of the telephone antenna, which was announced at the presentation.

Like the iPhone 4, the new model is available in white and black colors.

For people who love to show off the latest gadgets to others, it will be a disappointment that the new iPhone does not indicate anywhere that this is a 4S model, and not 4. Therefore, you will never distinguish a person with an iPhone 4S in their hands from the owner of an iPhone 4 .

The screen also remained unchanged. However, why change if competitors have not been able to oppose the iPhone 4 in this parameter in a year? The number of dots per inch (328) is still out of reach for other manufacturers, and besides, an IPS-matrix (or something similar in color reproduction and viewing angles) is also far from being found everywhere. True, in fairness, we note that on the instance of the iPhone 4S that we had for testing, the screen turned out to be slightly lighter than that of the iPhone 4. But, firstly, this is only visible in direct comparison, and secondly, perhaps it's just a consequence of the fact that the screens are from different batches. It is possible that if we took another iPhone 4, there would also be a lighter screen.

Siri Smart Assistant

So, we figured out the similarities, now let's talk about the most interesting - about the differences. Let's start with software differences. They are, in fact, only one, but very important and interesting. This is the Siri smart assistant. Note that it is an attribute of the iPhone 4S, not iOS 5. Therefore, the owners of the iPhone 4/3GS and iPod touch will not be able to use it. Below are screenshots of the menu. iPhone settings 4 (left) and 4S (right). Please note that in the first case there is no Siri, but in the second it is.

Siri is disabled by default. It must be activated through the "Settings" by moving the corresponding lever. Having done this, we will see the Assistant settings, as well as the choice of languages.

Currently only English, German and French are available. Moreover, given that there are three versions of English here, we can conclude that the accent is very critical for Siri. Of course, for Russian-speaking users, the question is very interesting when Siri will work with the Russian language. However, there is no answer to this question yet. It is possible that it is the need to adapt Siri for each country that will cause delays. iPhone release 4S to local markets.

Before starting the conversation, Siri warned us that it would be sending data to Apple. The moment, in fact, is not at all formal: you need to understand that Siri will send almost all the information that it finds from you: contacts from your address book, your location, the contents of your music collection ... But if you still trust Apple and are not afraid unauthorized use of your personal data, Siri will offer several commands for example.

The screenshot on the right clearly shows that Siri is integrated into all the main iPhone applications. Moreover, with its help you can not only get some information, but also perform some actions in these applications. This is the fundamental difference between Siri and, say, voice search in Android. There we can only find something on the Internet or on the device itself, but not make any changes. In addition, all previously seen implementations voice control an exact match was required. Siri, on the other hand, “understands” naturally formulated questions that do not contain the name of a specific application. It's hard to believe, it's something from science fiction films, but it really works! Let's give two examples.

First we asked (in English): what is the value of Apple shares? Siri replied: Apple Inc. closed at 422 USD today and showed data from Yahoo. After that, we decided to be mean and asked the same question, only about Microsoft shares. But this did not cause difficulties for Siri.

Note that we have not spoken Microsoft Corporation , but just Microsoft . However, Siri understood the question and very quickly (literally in a couple of seconds) found the answer. The next question was: Who is the President of the United States? Siri immediately brought up information about Barack Obama, finding it by two keywords / phrases - the United States and the President. However, the request to tell us something about Obama caused Siri to freeze.

I did not know Siri and such information as Madonna's year of birth, for example. Probably, the point is the limited bases that Siri can still access. Or in problems with interpretation. However, Siri understands some requests perfectly. For example: I need a bank in New York. Here's what Siri suggests:

And sometimes the intelligence of Siri is a real delight. For example, to the question “Do I need an umbrella?” Siri reasonably noticed that he did not know where I was, so he asked me to turn on the geolocation service (I had it turned off) or tell me where I was. The second seemed easier to me. I told Moscow and received not only a surprisingly “human” answer (“No, I don’t think it’s raining in Moscow right now”), but also a weather report for Moscow for the next few hours.

Look: the program is having a real dialogue with you. Here it is, the future! Moreover, not only the specific implementation of this technology in the iPhone is more striking, but also thoughts about how these technologies can be used in the future. Imagine the following scene. You go to the fridge and ask, “Can I have another piece of pie, or have I gotten too fat lately?” The refrigerator, which has a built-in webcam, takes a photo of you, analyzes your weight and height, and then replies: “It’s better to eat something less caloric, for example, a salad that lies on the top shelf; by the way, it will soon expire, so it’s worth finishing it quickly.”

Yesterday I would have called it fantastic. Siri proves that this will become a reality in the very near future. Computers have learned the main thing: to interpret human requests according to human algorithms. An example with the same umbrella is indicative. When I ask another person if I need an umbrella, he understands that the question is not about whether I need one at all, and even less about whether it can be used instead of a parachute (or for some other extravagant purposes). ). And about whether it is raining outside the window. The same associative chain is performed by Siri. In our country, the word "umbrella" is strongly associated with the concepts of "rain" and "weather". So why not teach this to the computer too? Apple - taught. Next is the matter of expanding the bases that the intelligent assistant can access and improving the recognition of questions. In our testing, it was the recognition of voice requests that was the most difficult part of working with Siri. Apparently, it will be easier for native speakers with this, although the same English has many varieties. And it’s not a fact that Siri will understand the Irish, for example, better than us. But, again, we emphasize that this is only a matter of time. And the time, apparently, is very short. By the way, Siri answers questions in a pleasant female voice (much more natural than in car navigators) - and this further enhances associations with science fiction films.

Performance

Another highly touted feature of the new iPhone is performance. Apple has equipped the smartphone with the new Apple A5 SoC, which, unlike the A4, is dual-core. Thus, if the iPhone 4 roughly matches the performance of the first iPad, then the iPhone 4S has reached the iPad 2. Let's check in practice how significant the increase turned out to be!

The comparison will involve the iPhone 4S, iPhone 4 and last year's iPod touch. All three devices were running iOS 5.0. At the same time, by the way, let's check how critical the smaller amount of RAM is in the iPod touch. The following applications from the App Store were used as benchmarks: 3D Benchmark (3DBench), GLBenchmark 2.1.0 (paid version), GeekBench 2.1.9 (paid version), CPUBench and Linpack Benchmark. We also used the SunSpider 0.9.1 browser test. So what did we get?

The free 3D Benchmark uses an eight-second scene from the game Defend London (purchasable from the App Store). Unfortunately, the duration of the test cannot be adjusted. Therefore, we are preparing in advance for a large error. We ran the test on each device three times. The table shows the best results for each of the participants. The top line is the number of frames per second, the bottom line is the time for passing the test.

iPhone 4	iPod touch 2010
60.192486 fps	59.285522 fps	56.542412 fps
8.290071 sec.	8.416895 sec.	8.825233 sec.

As you can see, the results do not differ much. At the same time, the error in the case of the iPhone 4S was less than 1 frame per second (the worst result is 60.120571 fps). The iPhone 4 had an error in the region of 2 fps, and the iPod touch had a scatter of results as much as 5 fps (the worst run was 51.357391 fps). How to interpret the results of the 3D Benchmark test? In principle, it is clear that the iPhone 4S all launches are better than the iPhone 4, and the iPod touch is worse than both iPhones. But, firstly, the difference is already very small (approximately at the level of error). And secondly, it clearly does not reveal the full performance of the iPhone 4S.

The next benchmark will be GLBenchmark 2.1.0. This is already a serious professional test, which is also used by Apple. For clarity, we will present in the table the results of only the iPhone 4 and iPhone 4S, as for the results of the iPod touch, then, looking ahead, we say that they are almost identical to the iPhone 4 (and this, by the way, proves that for games there is a fundamental difference between the iPhone 4 and no previous generation iPod).

So what do we see? iPhone 4S just utterly smashes last year's model. In the Egypt subtest, which simulates a game episode, the iPhone 4S outperforms the iPhone 4 by 5-7 times! In the PRO subtest, the difference is 3-6 times. If you look at the rest of the tests, you can only gain a foothold in the opinion about the superiority of the iPhone 4S. It is possible that Apple somehow specifically optimized the iPhone 4S specifically for passing this test. But in any case, the result is eloquent. Note that GLBenchmark only tests the graphics subsystem. Therefore, such a difference in performance will be felt only in those applications that actively use hardware graphics acceleration.

Now let's see how things are with the performance of processor cores and RAM. To do this, we run the GeekBench 2.1.9 for iPhone OS test (this is a multi-platform test; it also exists in the version for Mac OS X and Windows, however, the iOS version must be purchased separately).

The results are quite expected and understandable. The dual-core processor of the iPhone 4S is twice as efficient at floating point operations, and the iPhone 4S also has slightly faster RAM. The only thing that confuses is the fact that GeekBench incorrectly identified the iPhone 4S processor. But, again, the results look quite plausible.

In the free CPU Benchmark 2.0 test, the alignment turned out to be similar. Moreover, if we correlate the obtained results with the base of this benchmark, then we can conclude that the iPhone 4S processor is more productive than even the iPad 2. However, we could not verify this in other tests, because. We didn't have an iPad 2.

Left - iPhone 4 results, right - iPhone 4S

The iPod touch scored about the same CPU Benchmark as the iPhone 4. However, we were a little confused by the fact that among the results of the base there was an iPod 3G (apparently the previous generation iPod), which was faster than the iPhone 4 and iPod touch in 2010 . Yes, and the result of the iPhone 4 in the database was listed as 426, while we got only 391. Considering that the GeekBench database was updated in mid-August, and we tested in mid-October, we can conclude that the benchmark algorithms or counting mechanisms were somehow then changed over the past two months, resulting in such a discrepancy in the results.

Another test, already purely synthetic and demonstrating processor performance in floating point operations, is Linpack Benchmark.

Left - iPhone 4 results, right - iPhone 4S

If you run it with the default settings (Problem size - 200, number of runs - 50), then the test will pass quite quickly (iPhone 4S is faster, iPhone 4 is slower), and the results will differ several times. We set the Problem size to 1000, and reduced the number of launches to 5. With these settings, both devices passed the test much more slowly, but the final result turned out to be more plausible.

Left - iPhone 4 results, right - iPhone 4S

And the last point of our program is the SunSpider 0.9.1 browser test. For clarity, we display the results in a table (all results are in milliseconds; accordingly, the less the better).

	iPhone 4
3d	488,0	274,4
access	419,8	278,1
bitops	200,0	179,2
recursive	25,3	19,5
crypto	217,3	160,8
date	573,4	327,4
math	409,9	221,0
regexp	113,9	87,6
string	1109,0	690,1
Total	3502,0	2238,1

As you can see, the difference is about one and a half times, which corresponds to the difference between two generations of iPads (they had 3404.3 and 2182.2).

Camera

The last significant difference between the iPhone 4S and the previous model is the camera. In principle, the iPhone 4 camera was quite good. However, in this parameter, the iPhone is clearly not the leader among smartphones. The much cheaper Nokia N8, for example, had a better camera. Now Apple offers an eight-megapixel camera (instead of the previous 5 megapixels), and video resolution is 1080p (versus the previous 720p). Let's check how this affects the quality. We will compare the iPhone 4S camera not only with the iPhone 4, but also with one of the main competitors - the new Nokia N9, whose sales started a week before the iPhone 4S (read a detailed review of Nokia N9 in the near future). But there is no point in using the iPod touch in comparison: the camera is much worse there, it is not a competitor to smartphones.

First, let's try out smartphones in complex shooting modes. The first mode is shooting the cityscape at the beginning of twilight (mid-October, around half past six in the evening; it is already getting dark, the lights are on in the houses). First, we present reduced (up to 600 points horizontally) shots of all three smartphones. Shooting was carried out from one position, from a hand, in automatic mode (except that the frame format in Nokia N9 was changed from 16:9 to 4:3 in the settings - to resemble the iPhone). Several pictures were taken for each smartphone, after which the best one was chosen. Click to see the originals.

The next test is shooting in a room, at night, without an external light source. All three smartphones have a flash, so they coped with this task (and the iPod touch, for example, did not cope at all, since it does not have a flash).

iPhone 4

Nokia N9

Once again, the iPhone 4S and Nokia N9 go hand in hand. Pictures vary slightly in color. In my opinion, the iPhone 4S shot is more natural. But, at the same time, if you look at the original photos (they are available by clicking), then the inscription on the box (Hercules) is readable only on the frame of Nokia N9. But the frame of the iPhone 4 is significantly worse than both competitors in terms of clarity and color reproduction (an unpleasant bias towards yellowness).

And the last photo assignment: take a spread of the book with text. The test was carried out on a windowsill, in daylight. In principle, all three devices coped with the task, that is, the text on all the pictures was clearly distinguishable. However, there is still a difference between the pictures. As before, three pictures were taken for each smartphone, and the best one was chosen. The original photos are available by clicking on the pictures, but here we present fragments of the most difficult part of the book (where the pages were bent).

iPhone 4

Nokia N9

It is clearly visible that the complex fragment of the iPhone 4S turned out to be less clear, it seems that it is a little out of focus. Moreover, it was in all three pictures. In the photos of other smartphones, the focus is more uniform. The iPhone 4 shots turned out darkish.

We also note three details. First, the largest image size is obtained from the iPhone 4S. Less on the Nokia N9, even less on the iPhone 4 (you can judge for yourself by comparing the uploaded images). Secondly, Nokia has more settings. In particular, you can choose between wide (16:9) and full (4:3) format. In the first case, the resolution will be 7 megapixels, in the second - 8 megapixels. The third point: in terms of “rate of fire”, the iPhone 4S is faster than the iPhone 4 and about the same as the Nokia N9.

Finally, let's check the video shooting. Recall that of the three smartphones, only the iPhone 4S can shoot in Full HD. The rest shoot only 720r. And - the video shot on the iPhone 4S is really out of competition. It's just another level. Neither Nokia nor the iPhone 4 even come close to it. Download videos here: iPhone 4S (88.2 MB) , iPhone 4 (39.2 MB) , Nokia N9 (29.6 MB) . In the iPhone 4S video, pay attention to the detailing of the paving slabs - this is not the case in other videos. But do not pay attention to the shaking of the image: the video was shot on an outstretched arm, during a strong wind.

findings

The battery life of the iPhone 4S, in our opinion, is no less than that of the iPhone 4, although a full test in different modes and with different use cases has yet to be done. When will the official iPhone sales 4S in Russia, we will definitely return to this issue. In addition, we will test the iPhone 4S for stability of reception and data download speed over 3G - it is reported that these parameters of the new iPhone are better than last year's. And, we hope, by the time the iPhone 4S officially enters the Russian market, the Siri intelligent assistant will learn to understand Russian speech. Which, of course, we will also check.

Nevertheless, it seems to us that this article answers the main questions. First, the performance of the iPhone 4S is indeed better than that of the iPhone. Moreover, in 3D games, you can win several times. However, so far this statement is based on benchmarks, and not on real impressions. The reason is simple: the games currently available on the App Store were built with the best available performance on the iPhone 4. So you probably won't feel much of a difference if you download games on the iPhone 4 and 4S. An example of this is the benchmark from the Defend London game available in the App Store. On the other hand, improved performance (both in terms of graphics and processor) is a good start for the future. Apple is constantly increasing system requirements iOS, games are getting prettier, so within a year, the difference in performance between the iPhone 4 and 4S will likely be obvious without any testing.

Other major improvements are the camera and the Siri smart assistant. The iPhone 4S camera is indeed better than the iPhone 4. So don't listen to those who say that they just artificially increased the resolution. No, it's not just that. All in all, the iPhone 4S can compete with the best camera phones on the market. Therefore, if you need a smartphone that can take good pictures, then the iPhone 4S should be one of the main candidates for the purchase. Whereas the iPhone 4 at the moment looks already outdated in this parameter. By the way, in iOS 5 it is possible to edit pictures directly in the Camera app, and then publish them on Twitter from there. But we will talk about this (as well as other features of iOS 5) in a separate article.

Finally, the last unique feature of the iPhone 4S is the Siri smart assistant. It is difficult for me to evaluate it in terms of the user qualities of a smartphone. Probably, if functionality is the main thing for you, then Siri cannot (at least not yet) be an argument in favor of the iPhone 4S (we emphasize that it is not available on other devices, including the iPhone 4 with iOS 5). However, if you want to look into the future with one eye, Siri will give you such an opportunity. This is really news from the future - and, at the same time, a symbol of progress. Something like that stele from A Space Odyssey 2001.

In general, it seems to me that the purchase of the iPhone 4S is quite justified even for the owners of the iPhone 3GS, but not for those who have the iPhone 4. At least in the next year and a half for sure. And even for iPhone 3GS owners, I would recommend taking your time and waiting half a year until Siri gets the Russian language, and games appear in the App Store that can fully utilize the graphics capabilities of the iPhone 4S.

Today we will talk about Apple smartphones, which continue to haunt the modern world. The Apple review 4S we will start with a short introduction.

So, new smartphone from Apple, in three days from the start of sales, broke all imaginable and unimaginable records - about 4.5 million iPhone 4S were sold. In this article we will try to find out what has become so attractive New Product Apple for buyers. The price of the iPhone 4S was quite high, but this did not stop people around the world. Maybe it's an excellent camera, or maybe it's the high performance of the device? Let's try to talk about everything in order.

So let's start with the look. Apple iPhone 4S has minimal differences from the old one iPhone versions 3g. The device consists of two glass sheets, which are united by a metal frame. But on closer examination, small differences begin to emerge: now the metal edging is divided into four parts, the control buttons on the side surface have slightly shifted.

The size of the device is 115.2x58.6x9.3 mm, and the weight is 140 grams.

There is a touch screen on the front of the device, and a camera with a flash on the back, so there are no innovations here.

The assembly of the Apple iPhone 4S was made at a fairly good level: there are no squeaks during operation and backlash. But still, it is worth noting a few details: after a week of operation, small scratches began to appear on the smartphone case, so it is advisable to put the iPhone in a case, there is also a problem with the volume control button that is stuck. But the voiced problems were in the first games, now, probably, the situation has changed for the better.

The smartphone is available in two colors - white and black.

Sensor size Information about the size of the photosensor used in the device. Typically, cameras with a larger sensor and lower pixel density offer more high quality images despite the lower resolution.	4.54 x 3.42 mm (millimeters) 0.22in
Pixel size Pixels are usually measured in microns. Larger pixels are able to capture more light and therefore provide better low-light performance and a wider dynamic range than smaller pixels. On the other hand, smaller pixels allow higher resolution while maintaining the same sensor size.	1.391 µm (micrometers) 0.001391 mm (millimeters)
crop factor The crop factor is the ratio between the size of a full-frame sensor (36 x 24mm, equivalent to a frame of standard 35mm film) and the size of the device's photosensor. The number shown is the ratio of the diagonals of the full frame sensor (43.3 mm) and the photo sensor of the specific device.	7.61
ISO (light sensitivity) The ISO value/number indicates the sensitivity of the sensor to light. Digital camera sensors operate within a specific ISO range. The higher the ISO number, the higher the sensor's sensitivity to light.	64 - 800
Svetlosila Luminosity (also known as f-stop, aperture, or f-number) is a measure of the size of a lens aperture that determines the amount of light that enters the sensor. The lower the f-number, the larger the aperture and the more light reaches the sensor. Usually, the number f is indicated, which corresponds to the maximum possible aperture of the aperture.	f/2.4
Shutter speed (shutter speed) Shutter speed reflects the exposure time. Indicates how long the optics shutter remains open during shooting, and thus the amount of time the camera's sensor is exposed to light. The longer this time, the more light reaches the sensor. Shutter speed is measured in seconds (eg 5, 2, 1 second) or fractions of a second (eg ½, 1/8, 1/8000). Unlike DSLR cameras that use a mechanical shutter, mobile devices use an electronic shutter.	1/15 - 1/30000
Focal length Focal length indicates the distance in millimeters from the sensor to the optical center of the lens. The equivalent focal length (35mm) is the focal length of a mobile device camera that is equal to the focal length of a 35mm full-frame sensor that would achieve the same angle of view. It is calculated by multiplying the actual focal length of the mobile device's camera by the crop factor of its sensor. The crop factor can be defined as the ratio between the 35mm diagonals of a full-frame sensor and a mobile device sensor.	4.28 mm (millimeters) 32.58 mm (millimeters) *(35 mm / full frame)

The first item when buying a phone is just the screen size and how many inches it is. Today we will talk about the screen size of iPhones, because this question is of interest to many.

In fact, there is a lot of information about this, and since the iPhone is just a standard among phones, I will be very brief and try to show only the main ones.

What is the iPhone screen size?

Apple has long held its position with small screens, but the smartphone market still forced them to change their mindset and now you know how much the largest screen is on the iPhone. And if not, then the following list is made for you.

In it, I will talk not only about its size, but also mention its main characteristics.

First generation iPhone screen, 3G, 3GS, 4, 4S

For five generations we have used phones with such small screens. At that time, and this is the period from 2007 to 2011, this size was acceptable and it was enough for all modern tasks.

But if you look through the eyes of 2006, these are very small smartphones and you don’t really want to pick them up. There is little content on the screen, and playing games is generally inconvenient.

• 2G:
• 3G: 3.5 inches, LCD TFT, resolution 320×480, 163 ppi;
• 3GS: 3.5 inches, LCD TFT, resolution 320×480, 163 ppi;
• 4: 3.5 inches, LCD TFT, resolution 640×960, 326 ppi;
• 4S: 3.5 inches, Retina, resolution 640×960, 326 ppi.

All these phones have become a very significant part in the development of touch smartphones. It was thanks to them that the race for inches and ppi began.

iPhone 5, 5S, 5C, SE screen sizes

The relevance of the size of these particular phones remains to this day. Here you can find a compromise between ease of use and compactness.


If you are the owner of a not too big hand and you do not like when the phone sticks out of your pocket, then you should have one of these smartphones.

• 5:
• 5S: 4 inches, resolution 640 × 1136, IPS Retina display, 326 ppi;
• 5C: 4 inches, resolution 640 × 1136, IPS Retina + display, 326 ppi;
• SE: 4 inches, resolution 640 × 1136, IPS Retina + display, 326 ppi.

The quality of such screens is very amazing and has been proven by many users over the years. I think everyone has a friend who prefers this particular screen size.

iPhone 6, 6S, 6 PLUS, 6S PLUS sizes

Starting with the number six, the race for inches began in earnest. Now the Yabloko could boast that they did not have a miniature iPhone, but a real shovel.


Although, the further the development of smartphones goes, the more the term "shovel" loses its relevance. You will not surprise anyone with your 5-inch phone.

• 6:
• 6PLUS: 5.5 inches, 1920×1080 resolution, Retina HD, 401 ppi;
• 6S: 4.7 inches, 750×1334 resolution, Retina HD, 326 ppi;
• 6S Plus:

The screen size has grown significantly and now the iPhone is not miniature at all. You are holding a full-fledged smartphone with a very large diagonal in your hands.

In this generation of smartphones, Apple decided to stick to the sizes of the previous two generations. Why invent something new, if the old one is doing quite well.


Moreover, now the iPhone is associated with such large inches of screens. The time when people were surprised by large iPhones is long gone.

• 7: 4.7 inches, resolution 1334×750, Retina HD, 326 ppi;
• 7PLUS: 5.5 inches, 1920×1080 resolution, Retina HD, 401 ppi.

The appearance of black color in the line made smartphones more elegant. Now with a calm soul we say goodbye to the color Space Gray.
