As for individuals, in order to ensure their own safety, the following points should be noted:

　　1. When purchasing mobile phones and chargers, it is important to purchase products that have passed the national 3C certification from reputable stores. Do not buy counterfeit or inferior products for the sake of affordability.

　　2. It is best to use the original matching charger to charge your phone, and it is best not to mix chargers from different phones.

　　3. Do not wait for the phone to run out of battery before charging, as this will reduce battery activity and accelerate battery aging. It is best to charge the phone when it still has more than 30% battery power.

　　4. Non professionals are not allowed to disassemble mobile phones and their batteries at will. If the phone battery is a detachable battery, it is also necessary to turn off the phone before disassembling it.

　　Do not place your phone in an area with high temperature. The ambient temperature for working with mobile phones is generally between minus 20 degrees Celsius and 45 degrees Celsius. Exceeding or falling below this range may affect the normal use of the phone, and extreme caution should be taken when the temperature is too high.
