I am a professional selling mobile phone accessories and repair mobile phones, in this area of relatively rich experience. There are a number of reasons why the phone displays a charge but doesn't charge. The first way to see if it is the reason for the charger, you can change a new set of charger to charge and observe. If it can be powered in normally, it is the charger's problem. We can fix this problem with new appliances! The second is to change the new charger or not charge into the electricity, we can consider that it should be the tail plug line out of the fault. Let's put on a new tail plug board, and then charge the observation and try! The power supply indicates that the tail plug is faulty. Otherwise check for other reasons! The third may be caused by battery aging, and changing the battery can solve the problem. The fourth is possible motherboard line leakage, need professional maintenance personnel to deal with!
Mobile phone display charging, but the power does not rise, please check the following reasons: the charger used is the original charger, if not the original charger, then look at the output voltage and current data, to see if it is consistent with the original charger, if the output data is lower than the standard charging data, it may lead to this situation. Check whether the data cable is plugged in, both the mobile phone end and the charger end need to look. Excluding the above two reasons, it may be the fault of the mobile phone, it is recommended to shut down and restart, if the problem is still in, it is recommended to after-sales maintenance.
1, the use of the charger plug is not random original, charging current is too small, resulting in the battery can not be charged normally, the most intuitive display is that the battery power does not increase.
There is also a situation, the more charged the less electricity, or the charge is very slow, the general charging line contact resistance is large, to change one.
2, the ambient temperature of the mobile phone is high, if the ambient temperature is high, the battery is basically unable to be charged, and the charging environment needs to be improved;
Generally, after playing the game, this situation occurs, and it is suspected that the control charging procedure is cleaned up by the system, and the phone is restarted, and the battery is shown to increase immediately.

solution
1. Check whether the charging port on the mobile phone has entered foreign objects, such as toilet paper, fine particles, etc. If there is, you can gently remove the foreign body in the charging port with the embroidery needle.
2, the charger and the phone are in poor contact, then you only need to re-plug the charger into the phone.
3. Cell phone battery problems. This rarely happens, but if the phone cannot be charged, you should focus on checking the battery, if the battery is found to be swollen, then there is a problem with the battery and the battery needs to be replaced.
4. Check whether the small metal wire in the charging jack of the mobile phone is misplaced or rising. If it is misplaced, move it slowly with the embroidery needle to return.
