Reasons and solutions for failing to charge:
The first point: because we are used to putting the mobile phone in the pocket, the charging interface at the bottom of the mobile phone is easy to enter the ash, which causes poor contact between the interface and the power cord plug.
Therefore, when the mobile phone cannot be charged, please first check whether the interface at the bottom of the mobile phone is blocked by foreign bodies.
Second point: If there is no problem with the power interface of the phone, then we can use the replacement method to replace the charger and power cord that we usually use. At this time, if there is a computer around, you can connect the Apple phone to the USB port of the computer to see if it can be charged normally. If it can be charged, it means that there is a problem with the charger.
Third point: If we connect the phone with the computer, but also can not charge, at this time can borrow someone else's Apple phone power cord, see if it can be solved after changing the line. If changing the line can solve the problem, it means that there is a problem with the line, speed change the power cord.
Fourth point: If the above methods are not possible, then we can also try to shut down and turn on. Sometimes it may be the system that causes the phone to not charge.
There is also the problem of temperature, due to the physical characteristics of the battery, it is particularly sensitive to temperature, too high will cause problems, too low will lead to no charge.
Of course, this only happens in places where winter temperatures are particularly low.
If it is due to this problem that it cannot be charged, please first put the phone in the bed or air-conditioned room, let the phone at a normal temperature, and then charge it.
Fifth: If all the above methods can not solve your problem, at this time you need to recall whether the phone has been flooded or dropped.
Because water or falling may cause damage to the internal parts of the phone, it can not be charged. Of course, there may be other circumstances, in any case, at this time the mobile phone may have a hardware failure, personal advice is to send the mobile phone to repair the after-sales service for detection.
