HOW TO CHOOSE THE TABLET

Future owner of the new tablet needs to solve for himself for what tasks it is bought first of all: for reading e-book readers, viewing of movies, mobile games, distant work with corporate mail and documents or Internet surfing? It is necessary to be guided by the most frequent two-three tasks because attempt to buy the universal gadget capable it is absolute on everything, often leads to waste.

Platform

Definite answer to a question on what platform it is better to buy the tablet — Android, iOS or Windows — doesn't exist. As a rule, it is better to stop on the tablet of the same system, as your smartphone: they will be more compatible among themselves and it isn't necessary to be retrained.

Having decided on system, it is necessary to pick up a gadget on most it is fresher or at least the penultimate version. Otherwise the bought gadget can be incompatible with some programs. In spite of the fact that most of vendors try to update regularly an operating system on the devices to current version, some companies do it too seldom (for example, once a year), but also the bought pad can be laid already off, and then to it any more never see new system.

Processor

If the pad is bought preferentially for games, the central processor is the main thing what it is worth paying attention to. The processor is also responsible for operation of LTE, NFC modules and existence of function of wireless charging. The maximum resolution of the camera and display are also defined by processor power.
As the main criterion for a choice serve the frequency and quantity of kernels. Generally than digital designation in model of the processor is higher, it is more powerful than subjects. So, for example, at the Qualcomm company, chips with an index 4xx — are intended for the budgetary devices, with an index 6xx — for a mid-price segment and with an index 8xx — for flagships.

The video processor (or the graphic processor) in the modern mobile devices is a part of the central processor. Therefore, than the processor, especially a powerful video processor in it is more efficient. The most demanded and mass today — two series of graphic processors: Adreno (Qualcomm is used) and Mali (it is built in MediaTek, HiSilicon and Samsung chips).

The latest processors possess a certain inventory of power which will allow not to think of change of a pad the next several years. However, the cost of devices on their basis it is noticeable above. Big power has also a reverse side: productive processors consume more energy that affects operation of a pad from the accumulator, and besides powerful processors heat up in case of a maximum load more. The budgetary chips won't allow to launch resource-intensive 3D - games, but will help to spare that who buys a pad preferentially for Facebook, movies and e-mail.

It is worth marking that decided to buy production of Apple, it is possible not to worry concerning a processor choice. At the company of the relative a small model range that allows developers to optimize a game or application under the specific device, and to the user — not to be confused in number of gigahertz and kernels.

Built-in memory

The information volume which can be stored on the device depends on this parameter is both programs, and documents, and images, and video. The extent of the built-in memory has crucial importance if the choice is made between gadgets which have no connector for external memory sticks. For example, in iPad it is impossible to set the memory stick, but Apple offers models from 64 and 128 GB of the built-in memory which capacity is enough for storage of large volume of data.

If it is planned to photograph or shoot much video, as well as to play big games and to experiment with appendices, at once it is worth refusing gadgets on which less than 32 GB of memory are established. The device with a limited memory size can approach only if its owner is regularly ready to transfer a photo and video to the desktop computer or in a cloud service, making room on the tablet. Well and the option won't solve a problem of a lack of the place on a gadget with big games and appendices: to erase one programs to put others, and then to return back everything is not the best decision.

Random access memory

At the same time and bystry switching in between is responsible for start of several applications a random access memory (in abbreviated form to the RAM or RAM). Smoothness and speed of display of the interface of the most operating system, also in many respects depends on its volume.

The modern devices for the decision of daily tasks have enough 1 GB of a random access memory. And here fans of resource-intensive applications and games need at least 2 GB. As well as to pads which can work in the mode of start of several applications on one screen.

The most powerful pads are equipped 3 or even 4 GB of a random access memory. As a rule, it devices with the big diagonal of the display and high resolution. The price, naturally, too at the same time increases.

Size and display resolution

Screens with the diagonal of 7, 8 or 10 inches are most widespread among tablets. The small tablet (7 – 8 inches) is compact, easy, and other things being equal costs cheaper. On big it is much more convenient to type the text, to play games and to watch video.

The display resolution directly influences image sharpness. The difference becomes especially noticeable when reading, especially in small print or in detailed photos. The more the screen size, the bigger he requires permission that the image was perceived comfortably. In many respects, of course, it depends on specific features of sight of the specific person, and therefore the best decision can be made, having only personally got acquainted with this or that gadget. For a reference point it is possible to accept that the seven-inch gadget requires permission of at least 1280х720 points, for ten-inch — 1920х1080 (Full HD).

Very big permission on a small gadget is superfluous, but also, in some situations can turn back a font, unreadable because of the small size (especially it is characteristic of models on Android). So, resolution of 2560x1600 pixels for the small tablet is, as a rule, search. However and in this case features of personal perception can appear decisive.

3G and 4G

Some gadgets support only Wi-Fi, others (and they stand more expensively) — also connection to a mobile network. If it is supposed that Internet connection outdoors or operations won't be required or it will be necessary extremely seldom, then there is no sense to buy a pad with the module 3G or 4G. Especially as for Internet connection the pad can always be connected on Wi-Fi to the smartphone.

If mobile communication nevertheless is necessary, it is worth meaning that networks 4G, as a rule, provide speed above, than 3G, and it can be important, for example, in online games and when using services of stream video. For the Internet, mail and social networks it is quite enough and 3G.

Some pads can be used also as normal phones, that is to accept and make calls. It can be useful, for example, if the main means of communication was discharged.

Operating time from the accumulator

The accumulator capacity specified in technical characteristics in itself doesn't give an idea of time of an offline operation of a gadget without recharge. Vendors sometimes separately specify battery life, but it is necessary to understand that such digits are almost always uprated (the single vendor specifying exact time of an offline operation of the gadgets — Apple).

If the choice goes between two pads similar in all respects, but one of gadgets possesses more capacious accumulator, then most likely he also will longer be capable to live far from the socket, especially, if a difference in battery capacity essential. If at two pads identical technical characteristics, including battery capacity, but these gadgets differ in the screen size, then will have bigger self-sufficiency smaller of them.

By operation with a mobile network (4G/3G) pads with 4G will be significantly more gluttonous. In general the acceptable operating time for a seven-inch pad will be provided by the battery with a capacity from 3700 мА⋅h, for ten-inch — from 5000 мА⋅h.

Other characteristics

Other characteristics of a pad in most cases don't exert decisive impact on a choice, and some of them, for example, support of satellite navigation (GPS), is practically in all modern gadgets. Captiously it is worth studying other parameters when the pad is supposed to be used especially in the specific or professional goals — for example, for record of music or operation with photo/video. It makes a sense to those who looks for an alternative to a notebook to be guided by existence of the keypad in a set or an opportunity to acquire it in addition. And the stylus can be necessary for artists or amateur photographers.

Technologies don't stand still, something new permanently appears. For example, in an increasing number of pads NFC modules are set (technology of wireless data transfer on small distances which allows to connect one tangency a pad to the wireless speaker or earphones). Also build in the dactyloscopic sensor which allows to unblock a contact of a finger the device and provides additional data protection of the user many models.
