1, the charger does not match
Apple x supports the PD fast charge protocol, if you use QC or other types of fast charge head, there will be no matching problems, charging can not be carried out normally, you can change back to the PD protocol charger, and check whether the charger is lossy.
2. The data cable is damaged
If the data cable is broken or the interface is different, it can not charge the Apple x, you can replace the intact data cable, and note that it can only use the data cable of the USB and lighting interface, but not other interface data cable, it is best to use the original.
3. Charging interface problem
If the charging interface is blocked by foreign matter, or is directly damaged, it can not be charged, the solution is to clean the foreign matter and then charge, if the charger and data cable are good or can not be charged, we must get the mobile phone shop repair charging interface.
4. The temperature is too low
If the temperature is below 0 degrees, it will start the battery self-protection because the temperature is too low, although the charge is displayed but the power is not charged, you need to let the ambient temperature rise to charge normally, and avoid using Apple x in a low temperature environment.
5. The battery discharge is excessive
When the Apple x is not used for a long time, its battery power will be consumed for standby, and the internal voltage of the battery will be very low after frequent excessive discharge, and the activity of the lithium battery will be reduced, and the direct charging can not be charged, try to use the original 5V\/1A charger first, and the battery can generally return to normal after activation.
