The lifespan of a cell phone is indeterminate, and it usually lasts more than 3 years, but it varies.
Cell phone manufacturers only offer a one-year warranty, but most cell phones can last more than 3 years. Although cell phones have many parts, the service life is related to the environment, frequency, duration and usage. However, the quality of most cell phone parts meets the corresponding standards issued by the state, and can support the user for more than three years without any human damage. If the configuration is higher, the service life can even exceed five years after replacing the wearing parts.
The manufacturing cost of thousand-dollar phones is relatively low, so they are relatively lacking in the aesthetic appearance and texture of the phone. In the precision of workmanship and tightness can not be compared with high-end flagships, which leads to the use of the process is prone to some durability problems. Moreover, the thousand-dollar machine configuration can not meet some high-end needs, and can only be used to experience a stronger configuration. Therefore, in daily use, the lifespan of thousand-dollar machines can generally be guaranteed to be used for about two years.
Methods to improve the life of the phone
Battery maintenance: most of the current cell phone using lithium batteries, and lithium batteries have a life expectancy, in the full "charging and discharging" state, can be used about 300 to 600 times. Therefore, when charging the cell phone, the remaining battery power should not be less than 15%, disconnect after full charge. It doesn't matter how many times you use your phone below 15 percent, but if you do it for a long time, your battery life will drop dramatically.
Maintenance of external devices: The so-called external devices refer to the charging jack, earpiece speaker, and microphone. These three devices are directly exposed to the air, although the phone manufacturer has done some protection treatment, but inevitably there will be some dust and water into these positions. If not cleaned in time, it may lead to oxidation or poor contact in these parts, and in serious cases, even burn these devices. Therefore, if you want to do maintenance to the phone, you have to regularly clean these parts.
