In contrast to the appearance of the filling iPhone 4S was obvious improvement. Work device runs the same as the iPad 2, dual-core Apple A5, but with reduced up to 800 MHz maximum clock rate because of the desire to provide more autonomy. However, no slow imperceptibly.
Chip Apple A5, able to dynamically change its own clock, includes a central computer chip based on dual-core ARM Cortex-A9 MPCore with the accelerator NEON SIMD, plus video graphics processor Imagination Technologies PowerVR SGX543MP2, plus signal processing module image, which is responsible for features such as pattern recognition people, white balance, image stabilization.
For video graphics integrated into meets the A5 coprocessor Imagination Technologies PowerVR SGX543MP2 with two cores. Coming pocket game console Sony PlayStation Vita is equipped with the same SGX543MP4, but with four cores. In other words, the video graphics output iPhone 4S lies somewhere between Nintendo 3DS and PS Vita.
Although the clock A5 understated graphics power iPhone 4S, for example, in games will be modest iPad 2, because a 1-GHz processor to the last screen has to manage a large number of pixels in the third.
Differences Corps iPhone 4S (the bottom or right) of the iPhone 4.
RAM is 512 MB – like the iPad 2 and iPhone 4. You reasonably ask, why did not increase the amount of RAM to at least 1GB, how much more Android-equipped competitors have long been such a capacity, and some future devices promise to do an impressive 2 GB.
Apple itself has never revealed details about the amount of RAM your iOS-products, causing the curious to find out this information yourself, for example, by making a program surveys or even X-ray radiographic processors. Competing smartphones and tablets generally offer more memory, however, does not the fact that this superiority means increased convenience interaction with the end product. Some believe that the modest capacity of the RAM in iOS-device has a reason for such technological difficulties of integration with the processor or the desire to cut costs.
A5 processor is a complex “system on a chip” – actually a computer on one chip.
The answer came from … Microsoft. Steven Sinofsky, head of the Windows-division, has published a blog post relating to why the operation of a smaller amount of RAM is very important. The truth is that the minimization of the use of memory on low-power platforms like smartphones extends the battery life. In other words, the greater the amount of RAM installed in your device, without regard to the actual operation of its applications, the higher will be consumption.
Communications presented a hybrid chipset Qualcomm MDM6610 with simultaneous support for cellular networks GSM and CDMA, as well as modules Wi-Fi 802.11b/g/n and Bluetooth 4.0. Phone has a digital compass chip geolocation, accelerometer, triaxial gyro, ambient light sensor, proximity sensor. However, all this and so you know.
Rear camera with LED flash thorough upgraded 8-megapixel sensor and improved light-sensitive optics – photos come out with quality even in low light conditions. The camera can shoot video in 1080p-format at 30 frames / sec. For the development of CMOS image sensor is responsible Sony, but not the former long-term partner of Apple in the face of OmniVision Technologies. Frontal VGA-camera authorship of the latter remains unchanged.

3.5 Retina Display screen with a resolution of 960 by 640 pixels is familiar to us, and no longer looks as stunning as it was seen with the advent of the iPhone 4. Interestingly, the display will become less loaded contrast: the screen is characterized by a noticeably different color temperature, black is not so deep, clearly the overall bias in the green spectrum, transfer shed tones. But on the whole iPhone 4S color more pleasing to the eye.
Idle thoughts as to why the screen has not yet been added in the amounts are very simple answer: a matter of fact, why? If the producers are trying to attract consumers’ values: for example, Samsung Galaxy Nexus has a truly huge 4.65-inch display – not the fact that such device is convenient to operate with one hand. True, true, length and mobility of the thumb may well not be enough for it to reach the opposite side of the screen provided a strong hold of the phone in his hand. However, if you’re a long time enjoyed some Android-smartphone with a diagonal of the display, for example, 4.2 inch, iPhone-box in the digital world may seem a bit narrowish.
Masthead and the most expensive iPhone 4S now revealed a model with 64 GB of internal flash memory. Prior to that only media players iPod touch has similar capacity. In reality, the space available, of course, is somewhat different: the 16-GB iPhone 4S can be used 13.6 GB, 32 GB to 28.2 GB shrinking, well, a 64 GB phone is only 57.4 GB.Users for such disposition have long been accustomed, but still let you know that the available capacity flash storage iPhone 4S slightly lower than that in similar ways the iPhone 4 and iPod touch – the cause is likely to add “heavy» Siri.
Comparison of the iPhone 4 iPhone 4S revealed differences in speakerphone, microphone and speakers – the first a little louder, and the other transmits sound better the other party during conversations. It may seem that the desired performance simply deteriorated over the operation of the iPhone 4, but Apple actually upgraded audio equipment device. It is confirmed that the speaker volume iPhone 4S added somewhere 6 dB.
The latest iPhone 4S and the truth louder last year the iPhone 4.
Specialists iFixit, studying the innards of electronic devices, found that if the original GSM-iPhone 4 uses a rotating vibromotorchik with counterweight, the iPhone 4S set a linearly oscillating, as in the CDMA-version of the iPhone 4. This led to the fact that the vibrating phone is much more difficult to fall off the flat surface of the same table. Sam began to vibrate quieter, softer and less irritating.
Vibromotorchik iPhone 4S and GSM-iPhone model 4: linear oscillations against rotation.
The autopsy also showed that the capacity of the battery iPhone 4S added paltry 0.05 watt-hours.
In fact, the iPhone battery is kept constant for two generations.
A few days after the official presentation of its iPhone 4S web page with refreshed specifications, indicating that the new smartphone Apple has enhanced support for geolocation technology. Thus, in addition to work in the familiar Global Positioning System GPS, which manages the U.S., iPhone 4S received reinforcements from the Russian Global Navigation Satellite System GLONASS.
GLONASS constellation consisting of 24 satellites, covers almost the entire territory of the Earth. This system was launched in 1982, but only in October of 2011 completed its formation through the conclusion of the last satellite.
Differences from the GLONASS GPS.
Thanks to the joint operation of the GPS and GLONASS improved the quality of navigation in the real world, at exactly the same positioning double-system has no effect.Thus, the lack of signal from the satellites, for example, GPS in a given place and at this time is compensated by the GLONASS satellites, for example, two visible GPS satellites and one GLONASS is possible to calculate the position of the receiver – GPS-device in such a situation would be powerless.
During the announcement of financial performance of the Apple in the fourth quarter of fiscal 2011 CEO Tim Cook said that Russia was “more promising”. And the truth: “apple” products we have more and more popular. Again, there was information, if on January 1, 2012 Russia will increase customs duties up to 25% on those mobile devices that will work exclusively with GPS, – this is done, of course, in order to promote GLONASS. And rightly so, by the way.
Preparing the iPhone 4S.
In all other device has not changed. Sorry, not much you can tell the difference iPhone 4S and iPhone 4 – just all the advances made on a subtle level. The phone has no LTE, or diagonal display with enlarged or stereo or three-dimensional stereoscopic display without, no built-in stand. Nevertheless, iPhone 4S – excellent device with pleasant characteristics. On paper, it seems, gives Android-competitors, showing off the giant screens, incredible processor speeds, support for high-speed mobile communications – but in practice the iPhone 4S is one of the most comfortable, functional and powerful mobile phones.
Funny how experts evaluated the IHS iSuppli, production of the newest Apple iPhone 4S costs in exactly the same amount that was spent last year to build the iPhone 4.According to experts, the cost of the components of a 16-GB iPhone 4S is $ 188, which should be added to the production cost of $ 8, – the result is $ 196. The total costs of Apple, of course, the more, because how much money was invested in research and development.
IPhone sales unthinkable enrich Apple.
However, the greed of Cupertino is well known: for increasing the volume of internal flash memory Apple collects a disproportionate toll on consumers. For example, if 16, 32 and 64 GB of flash memory cost to itself at $ 19.2, $ 38.4 and $ 76.8, the retail 32 – and 64-GB model of the phone are 100 and 200 dollars more expensive than the initial 16-GB modification iPhone 4S.
