Many, in addition to contacts, store a lot of other information on the phone - write down their ideas and thoughts, numbers credit cards, memorable dates, various files, etc. That is, the phone replaces us immediately notebook and flash drive. And all sorts of useful programs, functions, options that modern cell phones are equipped with make this small device so multifunctional that sometimes you wonder.

Today, a telephone in our lives is not a rarity or a luxury, although some fifteen years ago it was hard to imagine that even small children would walk around with a tube in their pocket. And if at that time someone brave decided to dream up and imagine that phones in the near future would have - a touch screen, a camera, a video camera, radio, TV, the Internet, a navigator, a flashlight ... they would look at such a person as if they were crazy .

A mobile phone in a person's life is an indispensable assistant, it is beneficial to those who value their time and are not ready to waste it. Imagine how much time we would spend looking for things that we suddenly needed if this wonderful contraption did not lie in our pocket. Take at least car repairs and the search for some rare spare parts. Without a phone in our lives, we would have to travel to a bunch of stores and spend a lot of time. And then he called, found out (I found where it is cheaper), went and bought it. The benefits of a mobile phone are obvious - saving time and money.

For a business person, the use of a cell phone is the ability to negotiate, reach an agreement with partners at any time and in any place. It's hard to imagine how much it would fall work productivity if businessmen and entrepreneurs would not be able to conclude a contract, give an order or resolve any other issues while out of the office.

A mobile phone in the lives of some people is also part of the image. People buy certain models to show their belonging to a class. Of course, it happens exactly the opposite, more than once I noticed a respectable person in a luxury car with an old phone model. But this is rather an exception to the rule.

What is the use of a mobile phone for a person in an emergency situation? The one who got into difficult conditions and circumstances (perhaps he was on the verge of death), he knows what benefits a cell phone has. Often Cell phones save people's lives, protect them from danger and help in difficult life situations.

When I was a child, after reading the story "Old Man Hottabych", I was especially impressed with how Hottabych, with a snap of the fingers of his left hand, creates a telephone "from a single piece of the finest black marble." True, this phone had one drawback - it did not work: “In this case, it is clear why this phone does not work,” Volka said. - You made only a mock-up of the phone, without everything that is supposed to be inside. And inside the apparatus is just the most important thing. It was then that I was interested in the question of what is inside the phone. One such telephone - though not made of marble, but of Bakelite - stood on the table of my parents, and, driven by curiosity, I took it apart. After assembly, I had a lot of extra parts left, and my parents had to buy a new phone.

Processor: Qualcomm Snapdragon MSM8916 64-bit 1.2GHz // Operating System: Android KitKat 4.4 // RAM: 2 GB // ROM: 32 GB // Display: 5-inch (1280 x 720) HD Super AMOLED with Gorilla Glass 3 // Cameras: 13 MP rear camera with PureCel sensor and OIS, 8 MP front camera with LED flash // Sound: 1 speaker, 3.5 mm stereo output // Supported communication standards: LTE ( 4G), FDD Band 1,3,7,20; DL 150Mbps / UL 50Mbps, WLAN: WiFi 802.11 b/g/n/ac // Battery: 2300 mAh (lithium polymer), non-removable // Number of SIM cards: 2 micro-SIMs // Colors: platinum, gold, gray graphite // Dimensions (W x D x H): 146 x 71.7 x 6.9 mm Weight: 129 g

Over the past three decades, technology has changed significantly. Inside the Lenovo S90 you will not see what I saw: no carbon microphones, no magnets with wire coils and cardboard speaker cones, no pulse dial with gears, a spring and a split flywheel of a centrifugal speed controller. In a modern smartphone, there are not so many parts at all that you can disassemble it into - they are arranged into fairly large non-separable units, and the parts are packed inside the case extremely compactly. Disassembling and then assembling your own smartphone is not always possible. So Popular Mechanics did it for you.


1. The anodized aluminum case back is available in three colors: platinum, gold, graphite gray. On matte finish The case is not visible fingerprints, so the case always looks clean.

2. The frame increases the rigidity of the body. It also houses part of the structural elements. 3. Super AMOLED display covered with Gorilla Glass

3. Capacitive touch sensor (touchscreen) is integrated into the display. Also visible is the cable for connecting to the motherboard.

4. Motherboard (main) board with processor, graphics accelerator and memory. The board contains connectors for connecting the display, side power and volume buttons, main camera, front camera, battery and coaxial antenna cable. The board-to-board connector is located on reverse side fees.

It seems to me that a modern telephone is not only a way to communicate with the outside world, but also an entertainment center, since it is always with you. On the road, at work, on vacation, you can always listen to music, play, go online, chat in ICQ and, of course, make calls. So after all, what is the phone for - just to call or is it something more than just calls and sms?

sergunya
you can add more "show off"
Personally, I don’t understand why an mp3 player is needed in the phone. "Listen to music," is the answer. Well, I have never watched my classmates and acquaintances in general, so that they go with headphones, honestly. The first time, after the purchase, maybe ... Yes, and the quality of the majority is dubious and the phone is quickly discharged. Itself would preobrel with mp3 but only for the best quality ringtones.
The main thing is that the phone should ring, be convenient and sympathetic.

The phone was originally made to make calls, and then they began to attach games, the Internet, a camera, a camcorder, a player and other "conveniences" to it ... In my opinion, games in the phone are not needed at all (IMHO), in mine they were - deleted (only they take up space), I share the same opinion about everything else, I think that this is just the desire of manufacturers to increase the cost, because when one thing combines many functions that are not characteristic of it, these functions, as a rule, do not work very well ...

I totally agree with this

MariTa

Apparently you didn't have to travel long.
When your favorite songs are playing on your headphones, time flies faster. I'm already silent that some phones allow you to watch movies.

I always listen to music when I go somewhere far away, sometimes I watch movies, go online at the same time or communicate in ICQ. Many are surprised when they find out that I am not even at the computer now.

In terms of quality, it's all relative. The more expensive the phone, the better the sound quality. On my phone, the music sounds very good, but on the CX75 it's disgusting. Although the headphones sound evened out.

Advanced phones have increased capacity, so they can last as long as mp3 players without recharging, and they also make calls. And try to call the player


The main thing is that he combines all this in himself.


Naturally, this is something more. Only 10 percent use this something big to the full, the rest do not even suspect what features are in his phone. So it depends:
- from age. For example, my granny doesn’t even know what a phone book is and how to go there, she makes calls using hot keys
- from the type of occupation of a person. For example, rarely business man sitting and playing games.
- well, respectively, from the phone itself. Agree, the possibilities, for example SimensA50, are limited to sending SMS, squeaking-call and a couple of stupid games.

I agree that if there is a banal radio in the telephony, this is already good! MP3-shnik - even better! To be honest, I hardly understand why there is a camera in the phone - the quality of pictures is not up to cameras, video (I’d rather not say anything at all - after all, not everyone has enough money for an N90 with glass optics ...) ... Games - I didn’t think - I didn’t I never got to them, but .... There are a couple of programs - the first - AntiMoskito - REALLY scares away mosquitoes! And the second - a reader for books in txt format - this is also the question of long trips. So the phone is not only a means for calls and SMS.

(And if you also remember that my old 5100 had a full-fledged flashlight for its dust and moisture-resistant case - it's just irreplaceable thing on a hike and a dark entrance! )


All I have to do is call... don't even text...

I only need a phone to call, even sms is already broken to dial

If you know in advance that you will find yourself in extreme weather conditions, try to at least keep your smartphone in your pocket and use it only when necessary.

Phone charging errors

4. Leave your phone to charge overnight



Perhaps it is quite convenient to charge your smartphone at night while you sleep.

But, experts say: this is not a good idea.

If your phone is already fully charged but is still on charge, this can harm the battery over time and it will start draining quickly.

Please note that you do not need to charge your smartphone to 100 percent charge, as is commonly believed. Your phone's battery will thank you if you remove it before it reaches 100 percent.

*Try taking the phone off the charger when the battery is about 95-97 percent charged.

Try to charge it during the day instead of at night so you can turn it off when it's almost full, or set a timer.

5. You wait for the phone to drain to 0 percent and then charge it to 100 percent



Lithium-ion batteries, which are used in some smartphones, perform best when charged between 50 and 80 percent.

So says Shane Broesky, founder of Farbe Technik, a company that makes charging accessories.

Discharging the battery completely causes the phone to go into a "deep discharge state". This contributes to the fact that the ions become unable to hold a charge.

Experts say partial recharge of the phone gives the battery enough power to continuous work and battery protection.

In other words, recharging your battery is very similar to snacking between main meals throughout the day.

However, it is they who can ruin the phone. This is especially true for iPhone chargers. Chargers of this brand are quite expensive, but they are worth the investment.

Using third party chargers may damage your phone.

It is also reported that counterfeit chargers can also cause fires and even explosions.

Apple has urged people to turn in counterfeit chargers and purchase only original products at a discount.

7. Never clean your smartphone



Your smartphone is a carrier huge amount bacteria.

By comparison, toilet seats and pet food utensils contain fewer germs per square centimeter than your phone.

There are also devices with ultraviolet rays to sanitize your phone. Also, don't forget about your phone's charging port! It is there that the most garbage accumulates, because of which the phone may fail.

Lint and various debris from pockets or purses get stuck there and accumulate over time leading to serious connection failures.

Therefore, try to ensure that the port is always clean.

Clean it using a toothpick, a thin needle, or even back earrings. However, try to do this as carefully as possible so as not to scratch or damage the device.

8. Walking down the street, always keep your phone in your hands



The demand for stolen mobile devices on the black market is off the charts.

According to statistics, about 40 percent of all stolen smartphonesthey fall on the Iphone. A person walking down the street with a phone in hand is a potential target for a thief.

Therefore, for your own safety, try to put the phone away from prying eyes. Outside the home, use your mobile device only when necessary.
