In this era full of technology, mobile phones have become an indispensable partner in our lives, and with the faster and faster charging speed, many friends are still worried about the health of mobile phone batteries. Personally, I don't really care about the battery life of mobile phones, because now the speed of mobile phone iteration is very fast, and the speed of replacement is also very fast, and battery health is a minor problem in my opinion.
However, since some friends are worried, let's talk about how to make the mobile phone battery healthier, whether it is healthier to charge 80% or 100%, or there are other tips.
Most mobile phone batteries use lithium-ion battery technology, and their working process mainly includes two stages: charging and discharging. While charging, the current enters the phone battery through the charger and flows through the positive terminal of the battery. In this process, lithium ions are released from the positive electrode material of the battery, then pass through the electrolyte, and finally move to the negative electrode of the battery. At the negative electrode, lithium ions are embedded in the graphite structure to complete the charging process. At this point, the battery stores electrical energy and can be used for later use.
When the phone needs power, the discharge process takes place. The lithium ions of the battery's cathode begin to detach from the graphite and move through the electrolyte to the battery's cathode material. In this process, the battery releases the stored electrical energy to make the phone run. Current flows out of the battery, to the circuits and components inside the phone. This constant cycle of charging and discharging, in which lithium ions swap positions between the positive and negative electrodes, is figuratively called a "rocking chair battery".
In order to prolong battery life, the best way is to avoid overcharging and discharging. It is recommended to use the method of shallow charging and shallow discharge, that is, charging the mobile phone when the battery is low, and unplugging the charger in time after it is fully charged. At the same time, keeping the battery half charged when not using the phone for long periods of time can also help extend the lifespan. Such usage habits help to reduce the performance degradation of the battery and improve the service life of the mobile phone battery. Secondly, avoiding the use of the phone in extremely low and extremely high temperature conditions can also effectively protect the health of the battery.
