For friends who cherish their mobile phones, they will often ask themselves how much power is left on their mobile phones is the most suitable for chargingEngaged in lithium battery technology business for many years, the following is to share with you the accumulated knowledge about lithium batteries, how much power is left in lithium batteries to charge will be better.
Through long-term exchanges with battery R&D engineers of lithium battery manufacturers, summarized knowledge:Generally speaking, it is suitable to charge the phone between 20%-80%, but pay attention to unplug the cable in time after it is fully charged or do not play with the phone while charging. This is because within this power range, charging will cause minimal damage to the battery, while also ensuring the use of the phone.
Usually, when our phone's battery level drops to a certain value, the phone will automatically remind us to charge the device in time. This critical charge threshold is usually set at 20%. This setting is not only to avoid over-discharging the battery, but also to prolong the life of the battery. When the battery drops to this level, the phone will send out warnings in various ways to remind us to charge in time to avoid not being able to use the phone normally due to insufficient power.
At the same time, we should also develop good charging Xi. When the phone battery is below 20%, we should charge the device as soon as possible. During charging, care should also be taken to avoid overcharging to prevent battery aging. In addition, for mobile phones or tablet devices that are not used for a long time, it is recommended to charge them regularly to keep the battery active.
If the power is too low, such as the automatic shutdown of the mobile phone is often used, this is a deep discharge of the lithium battery, or even an over-discharge, which will lead to a change in the chemical structure of the raw materials inside the lithium battery, resulting in accelerated attenuation, and ultimately a shorter battery life
If the power is too high, it will cause the battery to swell, and even occur, this is mainly after the occurrence of full charge, but also continue to charge or fully charge while charging while playing with the mobile phone, because the mobile phone battery is fully charged, its internal raw material chemical reaction is relatively active, in addition to the external charger continuous charging, it is easier to cause the battery chemical reaction to be too active, the temperature rises or even out of control.
Therefore, timely charging in the 20%-80% battery range can not only protect the battery, but also ensure the use time of the mobile phone.
In short, in order to protect the mobile phone battery and prolong its service life, we should try to avoid recharging it after it runs out of power. At the same time, it is also very important to choose the right charging method and power range. Only in this way can we make better use of mobile phones and enjoy the convenience brought by technology.
