How many years you can use a Smartphone?

The most vulnerable component of a smartphone is the battery, which can be used for 5 years under normal use. And we often change mobile phones every two or three years. In fact, it is not that the life of the mobile phone is over, but that we want a more powerful mobile phone. Nowadays, a flagship mobile phone is very mature in terms of craftsmanship, performance, materials, and technology, and there will be no problems in normal use. However, playing games, watching videos, and even charging mobile phones from morning to night can cause great harm to the battery of mobile phones. Mobile phone batteries are parts that we don’t usually have access to. Because of material technology problems, the battery capacity and fast charging problems have not been solved until today.

The performance of mobile phone chips has increased dozens of times, and the chips have become processors or Soc; mobile phone memory has increased from tens of megabytes to hundreds of gigabytes, an increase of hundreds of times; mobile phone battery capacity has only increased by 2-3 times. Because of this gap, many times, our mobile phones are restricted by the mobile phone battery, and the life of the mobile phone is greatly shortened because of the battery life. The mobile phone battery is a lithium-ion battery, and its performance will drop rapidly after 500 times of full charge and discharge. 500 complete charging and discharging, that is, 500 charging cycles, and each charging cycle means that all the power of the battery is used from full to empty, and then from empty to full. It is not a simple charge once.

For example, We use the phone’s power from 100% to shut down, and then charge the battery to 100% again. This is a complete charging cycle. After 500 times, the battery capacity is basically only 60%, or even less, and the battery The power-off speed is very fast. At this time, we think that the battery life is expired and the battery needs to be replaced. After the battery is replaced, our mobile phone will return to its previous performance, and the mobile phone will be alive again. To a certain extent, if the mobile phone battery is replaced once, the mobile phone can be used for several years. If it is a flagship mobile phone, it can be used for 10 years.


In order to make the life of the mobile phone longer, we should pay attention to the following precautions when using the mobile phone battery:

  • Try not to charge the phone battery to 100%, because doing so will damage the battery more. Because the voltage will increase when the power reaches 100%, which will put pressure on the battery and make it work slower. In the long run, charging to about 95% can make the battery used longer.
  • Don’t charge while playing with your phone, because this method will generate a lot of heat, and the battery is mostly damaged by overheating, in severe cases, it may also cause a “mobile phone explosion”.
  • Try to use the original charger as much as possible. Chargers of different specifications will also cause damage to the battery. For example, the mobile phone supports 40W fast charge but chooses 66W fast charge, etc. This charging method is very harmful to the battery.
  • When using a mobile phone, running multiple programs will consume more power. Too much and fast power consumption will make the battery less and less durable.
  • Due to its own shortcomings, and multiple factors such as frequent usage and irregularities, the battery has become the least durable mobile phone hardware. In many cases, we only need to replace a battery to restore the phone to normal.

Many netizens have the experience of changing mobile phone films, leading most people to think that the life span of mobile phone screens is very short. In fact, this is not the case. LCD screens and OLED screens have been designed for more than 8 years, and LCD screens have even reached 16 years.

OLED screen: The life span is about 30,000 hours, the screen is on for 10 hours a day, and it can be used for 8 years.
LCD screen: The life span is about 40,000 to 60,000 hours. Even if the screen is on for 10 hours a day, it can be used for 11 to 16 years.
Problems with the phone screen are more of improper use.

The mobile phone screen refers to the lens covering the mobile phone display and touch screen. This layer of the lens is made of glass material, and its strength is several times that of ordinary alkaline glass. From the perspective of screen design, the hardness of the mobile phone screen has reached 7H, even a kitchen knife can not scratch the screen, and the key and the mobile phone do not need to worry about it. However, it is not the key that really scratches the screen, but the sand.

Overclocking: Increase the CPU clock speed to exceed the speed specified by the manufacturer, so as to achieve a method of improving performance. This can be achieved by adjusting the hardware settings to increase the chip’s main frequency. When the mobile phone is overclocked, the temperature of the processor will increase, and heat is the biggest factor that reduces the life of the processor.

Nowadays, many netizens like to play games and watch videos. Due to the performance of the processor and frequency reduction, the temperature control will be deleted, so that the performance of the processor will be fully released, but the temperature will also increase rapidly, for example, MediaTek Dimensity 1000, Qualcomm Snapdragon 888 processor temperature will reach 95 degrees or even 100 degrees. This temperature is very scary. If the mobile phone processor works in such a harsh environment for a long time, it will still have a great impact on the lifespan.

Smartphones are more likely to cause heat and frequency reduction due to size limitations. Therefore, mobile phone processors must strictly control power consumption. Computer CPU power consumption is mostly 65W, but mobile phone processors are required to be controlled below 10W and maintain high performance. This is why major manufacturers pursue 5nm technology. The mobile phone processor is forced to overclock, it will be more stuck because, at this time the processor is in an unstable state, a lot of data will have errors, then part of the computing power will be wasted on correcting errors. Therefore, overclocking still has a great impact on mobile phone processors.

Therefore, when the mobile phone is used normally, the life span of the processor is as high as 11 years, or even up to 20 years, under the condition of under-load and no overclocking. In normal use, the service life of the smartphone can reach more than 10 years. Generally speaking, the technology and technology for manufacturing mobile phones are now very mature. If mobile phones are used normally, there are few problems. If performance is not pursued, the service life can reach more than 10 years.

If a mobile phone only makes calls, takes pictures, and sends text messages, there is absolutely no problem even if it is a thousand-yuan mobile phone that has been used for 10 years and if a mobile phone is often used to play games, and when the battery is low, it is charged while playing games, then the useful life of this mobile phone will be greatly reduced. Usually, after 2-3 years of use, problems such as lag and battery heating will occur.

And heavy use of mobile phones, playing games while charging, usually not knowing how to take good care of their mobile phones, often bumping, falling on the ground, soaking, etc., this use method is doomed to the mobile phone life is not long. Therefore, if you want to use your mobile phone for a long time, you must take good care of your mobile phone.
