Method 1: The charger or data cable is broken: replace the charger or data cable.
Note: Please try to choose the original one for replacement, which will not cause harm to the mobile phone. If you think the original charger is not good, you can buy a better quality charger, but pay attention to the parameters of the charger must be the same as your original one. If the current is too large, it may cause damage to the main board of the mobile phone.
Method 2: The problem of the mobile phone interface: This is caused by the poor charging interface of the mobile phone, such as looseness. Please go to a professional mobile phone store for maintenance. Do not disassemble the machine by yourself.
Method 3: Battery problem: If it is determined that it is a battery problem, replace it. I don't recommend buying batteries at will. It is better to use original or high-quality batteries.
