The charge below 20% reminder is a self-protecting mechanism for the battery.
If the charge is less than 20% and it continues to be used, it will reduce the activity of the battery, which will damage the battery in the long run.
If the battery charge is less than 5% and continues to be used, it may cause the battery to be over-discharged, the internal voltage of the battery is too low, and the phenomenon of not being able to power on and not being able to charge may occur.
Small wide hands to offer mobile phone charging tips, no longer afraid of damaging the mobile phone battery ~ ~
1. Use the original charger
When charging the mobile phone, it is best to use the original charging equipment, and cannot choose the three no, non-formal channels to buy, non-original charger, otherwise it is easy to damage the mobile phone battery, and serious may cause the mobile phone to spontaneously ignite and explode.
2, the charging environment should be suitable
The best working environment for mobile phone lithium batteries is generally 0-35 degrees, when the charging environment temperature is too low, it will slow down the charging speed of the mobile phone battery, if the temperature is low to a certain limit, it may even be impossible to charge.
When the charging ambient temperature is too high, it will cause internal instability in the lithium battery. Because the lithium battery can not carry out good heat dissipation, which causes the fuselage to be hot, and may even cause the mobile phone to spontaneously ignite or explode.
3, the mobile phone should not be charged for a long time
The mobile phone is charged for a long time, and the battery reaches an oversaturated state, which causes the chemical reaction material inside the battery to passivate, reduce the degree of chemical reaction when the power is output, and then damage the battery.
4. Remove the phone case when charging
When charging, it is best to remove the phone case so as not to affect the heat dissipation of the phone, or try to choose a thin and light phone case. Plastic and leather mobile phone cases are better than silicone and metal mobile phone cases in heat dissipation.
