Several scientific charging tips about lithium batteries

The first principle: charge whenever you have a chance, and beware of low power. At present, mobile phone batteries are basically lithium batteries, which have no memory effect and can be charged and used at any time. When you’re away from home, once you see a place where you can charge, you can charge your phone at any time. It doesn’t matter if you charge it for a few minutes at a time. You can extend the phone usage time. Moreover, sporadic charging will not damage the battery. The characteristics of lithium batteries determine that overcharging or discharging will damage the battery. So, don't wait until the phone is completely dead before charging, as that will do the most damage to the battery. Generally speaking, when the remaining power is about 20%, it is necessary to charge. The second principle that charging will damage the battery at this time is to maintain the battery power within a certain range. Previously, the mobile phone power range recommended by my country Mobile's official Weibo was between 65% and 75%. It is believed that the battery power is maintained in this range and the lithium battery has the longest life. Uncle Hong feels that this interval is too small and it is difficult to take care of it in real life. Here, Uncle Hong suggested that the battery power of the mobile phone should not be less than 20%, and it is better to keep it between 20% and 80%, which can guard against over-discharge and over-charge. Generally, smart phones will have sound reminders or reminders of changes in screen brightness when the battery is below 20% and when it is charged to 80%. The third principle of always maintaining a certain amount of power, don’t always charge to 100%. If we are always full at one time when we eat, our stomachs will become uncomfortable afterwards. The battery of a mobile phone is the same. As mentioned earlier, lithium batteries must maintain a certain amount of power, and beware of over-discharge and over-charge. We can unplug it every time we charge to about 80%. Charge the battery to 100% will shorten the life. Fourth principle, do not plug in the charger all night/all day. Many people have the habit of plugging in a charger before going to bed. Often the plug is only pulled out the next day when I get up. The current smart phone will automatically stop charging after the battery is fully charged, but it will release a part of the battery when the phone is in standby. Because the charger is connected, the phone will automatically restart the charging process. But it's pretty bad. The fifth principle, the original equipment is true love, please use the original charger as much as possible, and use high-power chargers solemnly. The charger that each mobile phone is equipped with at the factory is the most suitable for the design. Using non-original chargers with different rated voltages and charging currents that match your mobile phone can easily damage the battery. Especially for high-power chargers with dozens of watts, the charging current is very large. If the charging parameters of your mobile phone are not matched, it will not only damage the battery of the mobile phone, but also may cause an explosion and fire risk.
