What iPhone 4s? The SAR level refers to the amount of electromagnetic radiation absorbed by the human body while using a mobile device. Screen, cameras and graphics
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. However, its hardware and software components allow you to easily solve most problems that are relevant today.
Smartphone hardware
The computing basis of the smartphone is the 2-core A5 chip. The clock frequency of each of them is 800 MHz. If such a CPU were installed on a device running Android, it would clearly not be enough for comfortable work. But Apple devices operate under iOS control, and this chip is enough for normal and smooth operation of the system. Of course, the latest innovations of this platform are this smartphone you won’t be able to feel it fully, but for most daily tasks it is quite enough. This includes watching movies, listening to music, and reading books - he can handle all of this without any problems.
Screen, cameras and graphics
The display of the iPhone 4S is quite modest 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 picture quality is not satisfactory. But to work on this small display not very convenient. There are two cameras on this gadget at once. The main one is based on an 8 megapixel sensor, which is enhanced by additional optical elements. The resulting photo quality is simply impeccable. The situation is similar with videos that are recorded in HD quality on this device. based on a 0.3 megapixel sensor. It is quite enough for making video calls. The connecting link graphics subsystem is PowerVR video accelerator SGX543MP2.
Memory
The memory subsystem in the iPhone 4S is organized in an interesting way. The characteristics of each smartphone of a given model may vary significantly. Every device can have different quantities integrated memory, and its volume varies as follows: 8 GB, 16 GB, 32 GB and 64 GB. The greater the capacity of the built-in storage, the more expensive the cost of the gadget, but at the same time the more functional the device becomes. Much simpler situation with RAM (random access memory), the capacity of which in any case in the “4S” is 512 MB. The only thing that causes criticism is the lack of an installation slot external storage. But this is a “disease” not only of this model, but also of all devices that run iOS.
Housing and ergonomics
The iPhone 4S smartphone has an unusual appearance. Characteristics, instructions and user reviews indicate that aluminum and glass are combined in the body of the device. It is this decision by American engineers that sets the gadget apart from its competitors. Essentially, it has no analogues. Side faces made of aluminum, and the front and back cover- from glass. Moreover, the entire front of the gadget is covered with impact-resistant “Gorilla Eye” glass. Otherwise, this is the same iPhone 4 of the previous generation, but with a more powerful CPU and an improved camera. Moreover, as noted earlier, its display diagonal is 3.5 inches, which means that operating it with one hand is not difficult.
Battery
The nominal battery capacity of this smartphone is 1432 mAh. It is integrated into the iPhone 4S. The description, characteristics and reviews of gadget owners indicate that one charge is enough for 2-3 days with an average level of use. But if the phone is used to the maximum, then you can count on 1 day battery life. On the one hand, the build quality of the smartphone is not satisfactory. But if the battery fails, it will be problematic to replace it yourself.
Software
As noted earlier, as a systemic software iOS is used for the iPhone 4S. Characteristics and reviews indicate that this is a well-tested system, the functioning of which raises no complaints. It immediately has everything you need for work. If something was not included in the basic configuration, then necessary software easy to install from the store Apple applications, and you can even find free programs.
Communications
The iPhone 4S has an impressive set of interfaces. Characteristics and reviews from gadget owners highlight the following:
- Full support for all networks mobile communications 2nd and 3rd generation.
- Built-in CDMA communication module.
- Wi-Fi allows you to transfer information at speeds of up to 150 Mbit/s when connected to the Internet.
- For sharing small files and also for connecting wireless headset you can use bluetooth.
- Wired port for connecting to a PC and for charging the battery.
- 3.5 mm audio port for connecting a wired stereo headset to a smartphone.
- A ZhPS transmitter is also integrated into the device, which allows you to easily turn this device into a full-fledged navigator.
The only problem is the lack of support for 4th generation networks. But at the time of the device’s release, they were not yet available, and installing such a radio module at that time was not entirely advisable.

Changes related to battery power have affected the battery life of the iPhone. The gadget can work up to 14 hours in operating mode, and about 200 hours in standby mode.
When working on the Internet, the battery will last for 6-9 hours, depending on whether the gadget is working on a 3G network or connected to Wi-Fi. Increasing the battery capacity also allows the phone to work up to 10 hours in video playback mode, and up to 30 hours in music playback mode.
Built-in flash memory overview
The gadget presented to the world can be purchased with different amounts of memory. Except standard options 8, 16 and 32 GB, now customers are also offered a model with 64 GB. The space that is actually available for use differs from that indicated in the specification. So, the actual amount of storage in the built-in memory is as follows:
- 16 GB –> about 13.6 GB
- 32 GB –> 28.2 GB
- 64 GB –> 57.4 GB
Despite the fact that buyers know about this situation even before previous devices, released by Apple, what is distinctive about the iPhone 4s is that the difference between the actual available built-in memory is greater than that of analogues such as the iPhone 4 or, for example, the iPod touch.
