When do you think your phone will be unusable?

Well, I think that if the phone is not used, he can no longer be used when he is very stuck, it cannot be said that the mobile phone is changed very frequently, when the mobile phone is really very stuck, it affects the normal use, then it is necessary to change to a new mobile phone, because this has affected your normal life.

In my opinion, the mobile phone can not be used when it is very stuck, the average service life of a mobile phone is three to five years, when it is used for a long time, it will enter an aging period, the screen sensitivity and the responsiveness of the fuselage are a lot sluggish, then this time it is time to consider changing a mobile phone.

My last phone seems to have been used for more than two years, and I liked it very much, especially the pixels for taking pictures, and in the end it was because it couldn't rush into the power and it crashed directly, so I gave it up.

The previous requirement for mobile phones was to take pictures with good pixels, but later with SLR, I was not so persistent, I hope that the running memory is larger, and the screen is larger, so that the experience effect is better when chasing dramas.

The current requirement is that as long as you can play **, you will not change.

I generally can't use it when it's outdated or the phone is broken, because sometimes the phone is outdated, a lot of software can't be updated, and the system is very slow, so I can't use it anymore. And if it breaks, it won't be used.

In my opinion, if my mobile phone is very stuck, and the memory is not enough, it is almost unusable, because at this time, many things in the mobile phone will be reluctant to delete, but the mobile phone has no memory, so it is better to change it, so you will not lose what you like, but also be able to live a better life.

For me, it's speed, if it's really slow, I don't think the phone works.

In addition, there is another point is memory, because sometimes I take pictures, I will save some of my favorite ** and the like, but without memory, I will think that this phone is of any use? It didn't work.

Hello! Since I use my mobile phone only for Internet access and communication, not for playing games, so I will not replace the mobile phone when the mobile phone is not broken, but due to the replacement of the mobile phone, the mobile phone configuration can not keep up with the software update, resulting in the use of the mobile phone is seriously stuck, I will also choose to change the mobile phone. So in my opinion, the above two points are when I think the end of the life of the phone.

The first mobile phone entered the Chinese market in 1987.

The benefits that mobile phones bring to people. Stay up-to-date with the latest global information.

With the development of mobile phones, a variety of applications have also entered people's field of vision. Among them, learning is one of them, you can look up words in the dictionary application on your mobile phone, and you can also take open classes.

It is more convenient for people to access the Internet without having to bring a computer to connect to the Internet. The convenience that this brings to people's lives is visible. It has changed people's lifestyles, and after that, Jueluzhou will definitely go in a more intelligent direction.

Mobile phone is mobile, or wireless, commonly known as mobile phone, originally just a communication tool, in the early days there was a common name of big brother, is a portable terminal that can be used in a wide range, the first by the United States Bell Labs in 1940 and the development of the battlefield mobile machine.

Summary. Because the mobile phone shows an estimated time of pure standby, but it cannot be pure standby when you use it, the more software you use, the higher the frequency of use, that is, the standby time is relatively short, that is just a reference time, if it is used, it should also be calculated according to your own use.

Because the mobile phone shows a pure standby estimated time, but you can't use the sedan car is pure standby, the more software you use, the higher the frequency of use, that is, the standby time is relatively short, that's just a reference time, if it's used, you should also sail according to your own use to calculate.

The mobile phone has set a limit for healthy use time, and when the use time reaches this setting, it will pop up to remind you that you need to search for a break, in order to avoid excessive use of the phone, you can set the screen time, and the use time has different meanings under different function options. If you use it in healthy use or youth mode, it is used to set the screen time, that is, the use time, and when the set duration is reached, the call function will be disabled.

The world's first mobile phone can be called a "brick". It weighs 2 pounds, the battery pack can only support half an hour of talk time, and it costs $3995.

Rudy Krolopp designed the world's first mobile phone for Motorola, the Motorola Dynatac, which caused quite a stir when it was released to the public.

Krolopp is 74 years old and has long since retired. But he is still thrilled when he thinks back to the past, and he thinks that the birth of the Dynatac mobile phone is truly a new era.

As the saying goes, "October is pregnant", and Motorola has been preparing for the "birth" of this mobile phone for ten years.

As the saying goes, "conceive in October", and Motorola has been preparing for the "birth" of this mobile phone for ten years. "One day in December 1972, Marty (Martin Cooper, then head of Motorola's R&D center) called me into his office and told me that the company wanted to develop a portable handheld**. Krolopp recalled, "And I responded, what the hell is this hand-held **?

At that time, the FCC was considering whether to allow AT&T to build a wireless service network in the U.S. market, and Motorola already had the idea of making wireless**. Motorola wanted to seize the market, so it gave Krolopp and his team only six weeks of development time.

Upon receiving instructions from Cooper, Krolopp immediately gathered his design team and immediately constructed a model of the phone. One day, Krolopp recalls, we put it in front of a couple of engineers. They were all stunned, no one had ever thought this thing would be so small (at the time).

There were only eight people in the room, Cooper said, and those who didn't have faith in it should leave now.

No one left. But it wasn't until 1983 that Dynatac was officially launched a decade later, during which time Motorola invested a total of $100 million in the world's first mobile phone. The main reason for this long wait is the lengthy preparation of the signal station and the basic components.

Krolopp said of Motorola's recent RAZR: "It's more like a blade and thinner than any previous phone. But that's just the tip of the iceberg. Technology will continue to advance, and everything will eventually become history.

If we could go back in time, would we have designed our phones to be the shape they are today? He pointed to the Razr's thin body and said, "We can do it in terms of design alone, but we can't make it." Because there were no small enough batteries at the time, and such small antennas were not technically supported.

Technology is really moving so fast! Krolopp sighed.

To our country it was about 1992 and '93.
