The average lifespan of a cell phone is two or three years, with some high-end models lasting longer, as long as four or five years.
The first reason to change a cell phone in general is the battery. The power of smartphones has led to the need to integrate more hardware into the phone, which requires the phone to require more energy. This exacerbates the problem of not having enough battery for the phone and the phone becomes charged more often.
Battery life is quickly drained, and now that cell phones are becoming more and more integrated, the cost of replacing a battery is not low, so the lack of battery durability has become an important reason for many people to change their cell phones.
The second reason is that cell phone use is getting more and more stuck, especially Android phone users change their phones much more often than Apple phone users. This is because Android phones in order to suppress the cost of cell phones, improve cell phone publicity, so the phone inside the factory will be pre-installed a lot of third-party software, resulting in cell phone system bloat redundancy.
Secondly, in the era of smartphones, cell phone systems are updated frequently, and every update takes up a lot of space on the phone, so the negative effect of more and more powerful cell phone functions is that the burden on the phone is getting bigger and bigger. And once users feel that their phones are stuck to the point of affecting their use, they usually choose to refresh their phones, or just change them.
Part of the use of cell phones:
1, business phones, as the name suggests, is to business people or people working in state institutions as the target user group of cell phone products. Because of the powerful function, business cell phone is very popular. Industry experts point out that "a good business cell phone should help users achieve both fast and smooth communication and efficiently complete business activities."
2, image phone is a kind of cell phone, but mainly the main image function of the phone. The world's first camera phone, the J-SH04, was manufactured by Sharp in Japan in November 2000.
This camera phone, not surprisingly, uses a CMOS image-sensing module (CMOS for short), which is more power-efficient than the CCD image-sensing module used in digital cameras at the time. The reason for this is that CMOS is much more energy efficient than the CCDs used in digital cameras at the time.
