Will the battery life be affected if the mobile phone is often used without overflowing the battery?

The battery of a smartphone is limited by the material and discharge principle, and it has a service life in itself. Generally speaking, after a mobile phone battery has undergone about 500 charge-discharge cycles, the battery capacity will be clearly attenuated, and the detailed performance is that it is not durable. And a charge-discharge cycle does not refer to the operation of plugging in and unplugging the charger, but a cycle in which the battery level of the mobile phone goes from 0 to 100% and then to 0. If the battery is charged from when the battery is 25% left, the charger is unplugged when it is 75%, and the battery is used for 25%, the battery only recycles 50% in this process, so it can only be counted as half a cycle. At present, most smart phones can still have about 50% of the power after one day, so two days are usually counted as a cycle. The life span of 500 cycles is 1000 days, which is almost three years. In fact, from the perspective of long-term storage of the battery, the battery power should not overflow. Because after the battery overflows, a relatively large voltage will appear inside it, and there may be excessive air due to internal chemical reactions, causing the battery to bulge. Therefore, if it is an old mobile phone that has been replaced, it is best not to store it after being overcharged. Generally, it is sufficient to charge it to about 90%. In addition, in the process of using the mobile phone, it is best not to wait for the power consumption to be clean, the mobile phone automatically shuts down before charging it. Because if the cell phone battery is over-discharged, its electrode active material is damaged and loses its ability to react. In severe cases, it can cause permanent damage to the positive and negative electrodes of the lithium battery. So when the mobile phone battery is less than 20%, it should be plugged in a charger. Finally, mobile phone batteries are also relatively sensitive to temperature. Generally, there will be greater attenuation in an environment below 10°C, and excessive discharge will also occur in an environment above 35°C. If you want to extend the service life of your mobile phone, it is best to guard against using your mobile phone in an environment that is too cold or too hot.
