Many consumers like to choose large products, but the bigger the screen, the better. Take the large-screen mobile phone on the market as an example. For products with a screen size of more than 7 inches, 1080P screen is actually used. The screen display effect of mobile phones is obviously not as good as that of small-screen mobile phones with the same screen material, so the display effect of large-screen mobile phones is actually not as good as that of small-screen mobile phones, and it is not advisable to blindly expand the screen size.

In addition, the larger the mobile phone screen, it means that the power consumption of the mobile phone will continue to increase. Although various mobile phone manufacturers have developed their own super flash charging technology, this technology can not fundamentally solve the problem of insufficient mobile phone power.

Although the battery capacity will increase with the increase of screen size, they are not in direct proportion. Strictly speaking, the bigger the screen, the shorter the battery life.

The increase in the weight of mobile phones is also an important reason why consumers reject the emergence of large-screen mobile phones. At present, the weight of most mobile phones in flagship machine is around 180g, and even the weight of many mobile phones with 6.7-inch screens has exceeded 200g. As an important tool in people's lives, most users carry it with them. Nowadays, mobile phones are getting heavier and heavier, which is also a great burden for users.
