IPhone A1387: overview, technical specifications

Apple products for easy identification are codenamed, for example, the code for iPhone A1387 (EMC 2430) is painfully familiar to fans of the iPhone 4s series, which in 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 using the device.
• Branded headphones.
• USB cable for recharging and syncing with iTunes.
• Charger for power from the mains.
• The key for removing / installing the SIM card.

Design

The appearance of the iPhone A1387 still rises fans in 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 has applied the hand to the design of the device, or they are really so delighted with the "sandwich of glasses", but it is thoroughly known that the exterior of the iPhone 4s is the best of its kind.

The case of the smartphone is made of glass and aluminum edges. There are no identification elements on the front panel, except for the cult button "Home". 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. On the top of the board, a 3.5 mm headphone jack and a power button have taken their place. On the left side there are buttons for controlling the sound. On the right side there is a SIM card slot.

Display

The smartphone Apple A1387 (iPhone 4s) inherited the screen from its predecessor. The same 3.5-inch display panel with the technology of double resolution - Retina. The display resolution is 960 by 640 points (PPI value is 326 points). IPS matrix iPhone is characterized by high brightness, rich color range and transmits the most natural and realistic picture. Since the appearance of these types of IPS-matrix and to this day technology is standard for both Apple products and for other manufacturers.

Performance and memory

Engineers from Cupertino are famous for their skills in developing chips, creating the most productive and energy-efficient processors. The iPhone A1387 is equipped with a proprietary dual-core Apple A5 processor with a clock speed of 1000 megahertz. As a graphics platform is the video subsystem PowerVR, proved to be the fastest among competitors, so phones from California are the best gadgets for gaming.

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 has achieved a high level of performance 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. The connector for a flash card is traditionally not in view of the low speed of operation of such and their unreliability.

Camera

Smartphone Apple A1387 (iPhone 4s) was the first in the history of Apple, which experienced a dramatic change in terms of photography. The 8-megapixel sensor impressed the audience. Due to its characteristics, the new lens knocked out the smartphone the title of the most popular camera in the world (according to Flickr service statistics). The iPhone A1387 camera transmits the most natural image, does not overload the photos with extra colors, skillfully avoiding the noises and artifacts that other cameras sin in phones of this class.

On the front side of the phone is a front camera with VGA-resolution, which is perfect for performing utilitarian functions, calls on FaceTime. Despite the modest resolution, many owners of the device do not hesitate to do with this camera selfie.

Battery

Apple always with special pride and pomposity is talking about the time of their gadgets from a single charge. In the case of iPhone 4s, the manufacturer announced that the smartphone is able to survive:

• Up to 8 hours of work during a call;
• Up to 6 hours of 3G Internet usage;
• Up to 9 hours of using Wi-Fi;
• Up to 10 hours of video playback;
• Up to 40 hours of music playback;
• Up to 200 hours in standby mode.

Naturally, in the case of gadgets, such statements are treated with skepticism, since laboratory results are often significantly different from those encountered by an ordinary user. The operating time depends on many external conditions, including cellular network coverage, air temperature (the smartphone can not cope with the cold and turns off), the level of battery wear and the programs used. Therefore, a battery with a capacity of 1450 milliamps 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 operating system iOS. The California corporation seriously declares that they were able to develop the safest and most advanced operating system in the world. Someone will not agree with this, but the analogs are really far from the development of Apple. IPhone 4s began life with the preinstalled iOS 5 and received updates up to iOS 9 of 2015 release.

The system is equipped with a basic set of programs, including a browser, mail client, player and many others. It is possible to install third-party programs that operate in protected mode without the possibility to have any negative impact on the components of the system. Roughly speaking, applications can not access the user's personal data and transfer them to others without the user's permission.

Instead of concluding

In the dry balance, despite the long life cycle and the inevitable technological and moral aging, iPhone 4s is an exemplary smartphone, a worthy representative of the market, whose capabilities are enough for most users.
