The reasons and methods are introduced
< br >
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.
< br >
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.
< br >
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.
< br >
Fourth point: If the above methods are not possible, then we can also try to shut down and turn on. Sometimes there may be a problem with the system, causing the phone to not charge.
< br >
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.
< br >
Fifth: If all the above methods can not solve your problem, at this time you need to recall whether the phone has water or been dropped. Because water or falling may cause damage to the internal parts of the phone, it can not be charged.
< br >
Of course, there may be other situations, in any case, at this time the mobile phone may have a hardware failure, personal suggest that you will introduce the reasons and methods of the mobile phone

1, the battery loss is excessive, has been completely damaged
In general, this situation is relatively rare, you can first check the battery health through our way of education. In normal use, the battery health of the iPhone is above 85% in a year, and more than 75% in two years.
But if you use it for a year and it's 80% off, there are only two possibilities, one is that you bought a fake,
The second is that you often commit the battery damage behavior mentioned in the previous section. I have seen people, because playing card games almost a few times a day to charge, as a result of nearly half a year, the phone battery health has dropped to 78%.
2, battery management IC damage
Most of this situation is because the mobile phone fell on the ground led to the motherboard components out of welding, the probability is very small. If the battery is not charged and the motherboard is damaged, the store will charge you more than 500 so-called replacement motherboard fees, in fact, only need more than 100 replacement power IC is good.
3. Non-original charger, charging cable damaged
The reason why the wireless charger has a reaction but cannot be charged:
< br >
one
< br >
Whether the phone model supports wireless charging or whether the wireless charger matches.
< br >
two
< br >
Whether the wireless charger indicator is displayed normally.
< br >
three
< br >
Mobile phone protective shell and other wireless charger external factors.
< br >
four
< br >
The transmitter power of the wireless charger may also lead to the reason why wireless charging can not be used.
