What are the advantages and disadvantages of smart phones?

The biggest advantage of smart phone is that it can install all kinds of application software, but the disadvantage is that the standby time is much shorter than that of ordinary mobile phone.

Let's make a brief analysis:

1, benefits:

1) The simplest summary is "convenience": you can make voice calls, text messages and video communication anytime and anywhere, and you can surf the Internet at any time (including browsing the web, sending and receiving emails, watching movies, etc.). ). Of course, this needs to be done in a network environment.

2) Smartphones can also take photos, move the hard disk (now the mobile phone has a large memory and can also be connected with an SD card), read and even edit files. Smart phones have partially realized some functions of computers to some extent.

2. Disadvantages:

1) Simply put, it is "dependence": people, especially young people, can't live without their mobile phones, and they panic when they are not around. This has become a feature of the new era, and it has also brought many interpersonal relationships and even social problems.

2) Some young people rely heavily on mobile phones and play them anytime and anywhere (including chatting with friends and playing games). ), which has a negative impact on their physical and physiological health, such as thumb (hand/finger numbness and deformation), cervical pain and even deformation, and decreased vision; It also brings some psychological problems, including the dependence mentioned above.

3) Related to the second item: memory declines. Because of the convenience of smart phones, people don't like to use their brains, for example, they can't remember their own phone numbers (I have a deep understanding of this point. At first, I was able to write down more than 100 commonly used phone numbers of relatives and friends, but with the use of mobile phones and smart phones, I can only remember dozens of phone numbers at present); For example, computing power is declining-because of the calculator function of smart phones.

4) Indirect or direct social harm: In addition to the above problems, people's bad habits of using mobile phones will also lead to serious consequences due to specific environmental conditions, such as car accidents caused by playing mobile phones while driving. (Of course, this is not the problem of the smartphone itself, but the problem of people. )
