If the wireless charger can't charge the phone, please try:

1. use original charger and data cable to connect the power to charge.

2. for battery dismountable mobile phones, you can turn off the battery and try to use cotton swabs to clean battery contacts and mobile phone charging interface.

If wireless power is not charged, the reasons can be investigated from the following aspects:

1. does the mobile phone support the wireless charging OR wireless charger?

Sometimes the wireless charger doesn't respond. First of all, it depends on whether the phone model is supported or not, and the wireless charging coil is not needed.

A. mobile phone built-in wireless charging receiver: directly on the wireless charger can be charged, such as Samsung S6, NOKIA Lumia920, Google's Nexus4/5 and so on.

B. mobile phone reserved wireless charging receiver terminal contacts: need to install wireless charging receiver to achieve wireless charging, such as Samsung's S3/S4/Note2/Note3.

C. mobile phone itself does not support wireless charging at all. It needs to install a wireless charging back rack to achieve wireless charging, such as apple iPhone5/5s/6/6s.

2. whether the radio charger indicator is normal

Secondly, the wireless charger around the famous brand has LED lights, when the mobile phone is charged on the wireless charger, the LED lights around the wireless charger will be lit up, or some are the hints, showing the use state. Sometimes it is slow response. It takes a few seconds to recharge, and sometimes it has to be replayed.

3. mobile phone protection shell and other wireless charger external factors

Then check whether the phone is on the back center and place it at the center of the wireless charging board. When you check the inclusion between the mobile and the wireless charging board, you may not be able to charge it properly. Check and check the back shell of the mobile phone. If the protective handset is too thick, it may hinder the wireless charging.

4. conditions for the normal work of the wireless charger

Finally, the power of the wireless charger may also cause wireless charging. The short circuit current of the receiver output can reach 1A, and the actual charging is only about 0.3. The voltage of the cell phone is directly reduced to 3.9V. This voltage can not reach the rated voltage of the battery, and the maximum working current of the wireless transmitter is 600mA, and the charging of the smart phone needs more than 700ma~800ma, so the wireless charge is charged. If the power of the transmitter is too small, the charging will not be charged.

Most of the power supply is not related to the setting or motherboard circuit.

Suggestions are as follows:

1. Restore machine factory setting;

2. If it is still checked, if the charging interface is damaged,

3. If most of them are mainboard battery, they can only be repaired by customer service.
