Extended information] 1. Mobile phone, the full name of mobile ** or wireless**, commonly known as mobile phone, was originally just a communication tool, and was commonly known as "big brother" in the early days, which is a portable ** terminal that can be used in a wide range, and was first developed from the battlefield mobile machine manufactured by Bell Labs in 1940.

Second, in 1958, the Soviet engineer Leonid. Kupriyanovich invented the -1 mobile**, and in 1973, American Motorola engineer Martin Cooper invented the world's first commercial mobile phone. After the 2G era and the 3G era, it has developed to the 4G era so far, and the 5G era is also closely followed, and 5G has been commercialized in China.

3. Smartphones refer to personal computers, which have an independent operating system, most of which are large-screen machines, and are capacitive touch screens, and some are resistive touch screens, which are powerful and practical. It is a general term for a type of mobile phone that can be installed by the user himself, including a program provided by a third-party service provider, such as a game, to continuously expand the functions of the mobile phone through such a program, and to achieve wireless network access through a mobile communication network."

4. Broadly speaking, in addition to the call function of a mobile phone, a smartphone also has most of the functions of PDA, especially personal information management and browser and e-mail functions based on wireless data communication. Smartphones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also provides a broad stage for software operation and content services. Many value-added services can be used in this regard, such as:

Fifth, if we trace back we will find that the concept of mobile phones appeared as early as the 30s, when Bell Labs, the largest telecommunications company in the United States, began trial production. In 1930, Bell Labs created the first so-called mobile telecommunications**. However, because of its size, researchers had to put it on a shelf in the lab, and slowly people forgot about it.

Sixth, the development of 5G also comes from the growing demand for mobile data. With the development of the mobile Internet, more and more devices are connected to the mobile network, new services and applications emerge one after another, and the global mobile broadband users are expected to reach 9 billion in 2018, and by 2020, the capacity of the network is expected to increase by 1,000 times on the current network capacity. The explosion of traffic will bring serious challenges to the network.

I hope my reply will help you.

Thank you for your question!

There is no standard answer to the question you mentioned, because everyone's situation is different, and the requirements for the use of mobile phones are also different. For example, for the elderly, no matter how good or high-end the smartphone is, it is not as good as the elderly machine. Therefore, what suits you is the best, and the cost performance is also the highest.

iqooz3 I think the price is quite high, and it is a thousand-yuan product that exceeds expectations. Compared with models of the same level, it has advantages in performance, battery life and heat dissipation.

There is a Snapdragon 768 mid-range processor, a 4400 mAh battery + 55W flash charging, and the screen supports 120Hz high brush. Full coverage cooling system, 64 million pixel triple camera combination! The price of 1699 yuan is extremely high in terms of cost performance.

Let's wait for the Snapdragon 888 CPU phone to be fully launched. At present, it seems that Xiaomi 11 has only been listed, and other 888 has not yet been officially listed.
