Apple products for convenient identification are equipped with a code name, for example, the iPhone A1387 (EMC 2430) code is painfully familiar to fans of the iPhone 4s series, which at one time became one of the most recognizable and popular smartphones in the world. The code name, which is often confused with the serial number, implies a gadget with a certain set of technical characteristics and specific specifications of the cellular network.
Equipment
What lies in the box with the iPhone A1387?
- Instructions for working with the device.
- Branded headphones.
- USB cable for recharging and syncing with iTunes.
- Charger for power from the mains.
- Key for removing / installing a SIM card.
Design
The appearance of the iPhone A1387 is still elevated by fans to the category of works of art as the most unusual and elegant for a smartphone. It's hard to say whether they are affected by the fact that Steve Jobs himself had a hand in the design of the device, or whether they really are so impressed by the “sandwich made of glass,” but it is thoroughly known that the exterior of the iPhone 4s is the best of its kind.
The smartphone case is made of glass and aluminum edge. On the front panel there are no identification elements, with the exception of the iconic “Home” button. The back of the iPhone A1387 is an identical block of glass, in the upper left corner there is a camera. At the bottom there is a 30-pin connector for recharging and syncing with iTunes, a microphone and speakers. At the top, a 3.5 mm headphone input and a power button took their place. On the left side there are buttons for controlling sound. On the right side is a slot for a SIM card.
Display
The Apple A1387 smartphone (iPhone 4s) inherited the screen from its predecessor. The same 3.5-inch display panel with technology of double resolution - Retina. The display resolution is 960 by 640 pixels (PPI value is 326 points). IPS matrix iPhone has high brightness, rich color range and transmits the most natural and realistic picture. Since the advent of these types of IPS-matrix to this day, technology has been the standard for both Apple products and other manufacturers.
Performance and memory
Cupertino engineers are famous for their skill in chip development, creating the most productive and energy-efficient processors. The iPhone A1387 has a proprietary dual-core Apple A5 processor with a clock frequency of 1000 megahertz. As a graphics platform, the PowerVR video subsystem acts, which has established itself as the fastest among competitors, so California phones are the best gaming gadgets.
Also under the hood of the smartphone there was a place for 512 megabytes of RAM. By current standards, such a volume seems ridiculous, thanks to careful optimization, the manufacturer achieved a high level of productivity and a low threshold for unloading applications from memory. Both factors have a positive effect on the objective user experience.
The amount of main memory varies from 8 to 64 gigabytes, depending on the model. According to tradition, there is no connector for a flash card in view of the low speed of those and their unreliability.
Camera
Smartphone Apple A1387 (iPhone 4s) was the first in Apple's history to survive a dramatic change in terms of photography. The 8-megapixel sensor impressed the public. Due to its characteristics, the new lens knocked out the smartphone as the most popular camera in the world (according to statistics from the Flickr service). The iPhone A1387 camera conveys the most natural image, does not overload photos with superfluous colors, masterfully avoiding the noises and artifacts that other cameras sin in phones of this class.
On the front side of the phone is a front-facing camera with a VGA-resolution, which is perfect for utilitarian functions, FaceTime calls. Despite the modest resolution, many owners of the device do not hesitate to take a selfie with this camera.
Battery
Apple always speaks with particular pride and pomp about the operating time of its gadgets on a single charge. In the case of the iPhone 4s, the manufacturer announced that the smartphone is able to survive:
- up to 8 hours of work during a conversation;
- up to 6 hours of using 3G internet;
- up to 9 hours of Wi-Fi use;
- up to 10 hours of video playback;
- up to 40 hours of playing music;
- up to 200 hours standby time.
Naturally, in the case of gadgets, such statements should be treated with skepticism, since laboratory results are often significantly different from those encountered by the average user. Operating time depends on many external conditions, including cellular network coverage, air temperature (the smartphone cannot cope with cold and turns off), the level of battery wear and the programs used. Therefore, a battery of 1,450 milliamperes of hours shows very subjective results for each individual user.
Software
The main advantage of the iPhone Model A1387 (EMC 2430) is its software component - the iOS operating system. California Corporation seriously claims that they were able to develop the safest and most advanced operating system in the world. Someone will not agree with this, but analogues are indeed far from Apple's development. iPhone 4s began its life with pre-installed iOS 5 and received updates until iOS 9 2015 release.
The system is equipped with a basic set of programs, including a browser, email client, player, and many others. It is possible to install third-party programs that work in protected mode without the ability to have any negative impact on system components. Roughly speaking, applications cannot access the user's personal data and transfer them to third parties without the permission of the user.
Instead of a conclusion
The bottom line, despite the long life cycle and the inevitable technological and moral aging, iPhone 4s is an exemplary smartphone, a worthy representative of the market, the capabilities of which are enough for most users.
