Check whether the battery connection connector is firmly in contact Wireless chargeGuard plate , if the connection joint is not strong, tighten the wireless charging protection plate in time; Check whether the battery is damaged, if the battery is damaged, you can immediately replace the new battery; Check whether the battery charger is damaged. If the charger is faulty, you can go to the maintenance point for repair or replace the charger with the new wireless charging protection board .
Change the charger, the voltage is higher than 12 volts, and the charger is charged within 18 volts, so that the electricity is directly rushed into the wireless charging protection board The battery protection board is generally located at the top of the battery, and each battery has a battery protection board designed for it. All mobile phone batteries have a protective plate. It's made of lithium batteriesThe characteristics of the lithium battery charge and discharge cut-off voltage is 2-0V, and then find a voltage range will cause harm to the battery, serious and even lead to explosion, so the mobile phone lithium battery, all lithium batteries must have a protective plate, generally packaged in the battery, in the golden finger part. Cell phone batteries are all protective boards. But the discharge current allowed is small. Two identical batteries can be connected in series with the same capacity, but the voltage is doubled to 4 volts. There must be a battery protection board in the mobile phone lithium battery. There is a circuit board in the gap between the lithium battery inside the mobile phone, and this board isIt's a protective plate for a lithium battery. The mobile phone lithium battery protection board is composed of several non-conductive fiberboard, and then wrapped with a layer of oil on the outside, which can protect the battery and avoid the role of overcharging the battery and short circuit. 1, the phenomenon that the lithium battery pack does not discharge is manifested as: the lithium battery pack is loaded into the device after being charged, the device cannot work, and the open circuit voltage of the battery pack does not change or changes little. 2, what happens when the 1V battery cell is charged to 2V: Will the battery capacity be increasedImprove, feel very good, standby time increases, but will reduce the battery life. For example, 500 times, reduced to 300 times. In the same way, overcharging the 2V cell will also reduce the life span. Lithium-ion cells are delicate. 3, the BM on the protection board is mainly to turn off the charge and discharge circuit when overcharging, overdischarging, and high temperature. Prevent cell damage, explosion. 4, BM is lithium battery, PD is pd fast charge. Solar cell BM is a lithium battery. The BM on the protection board is mainly to turn off the charge and discharge circuit when overcharging, overdischarging, and high temperatureStop cell damage, explosion. pd fast charge is a fast charge specification developed by USB-IF organization, and is one of the mainstream fast charge protocols at present. 5, the scientific and technological content of mobile power is not high, so it is difficult to judge the true or false, but it can still be seen from some details: first, look at the shell of the machine basically a product appearance workmanship represents the quality level of the product. Even if it is counterfeit in the exquisite shell, the overall industrial design is also a gap with the real thing. 1, shutdown charging test. Replace the charging position wireless charging protection board , eliminate the plug caused by poor contact intermittently led to replace the standby charger if conditions allow for testing. Or send the repair test to boot charging, such as the mobile phone is equipped with a third-party plug-in such as charging doctor, it is recommended to uninstall the test. 2, wired charging and wireless charging have failed, this may be the phone's charging control circuit has a problem. This problem requires a professional to check and repairMHM. It is recommended that you send it to a professional repair shop for inspection and repair. 3, when there is inclusions between the mobile phone and the wireless charging board, it may not be able to charge normally. Please check the back of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge. Please use the original Samsung charger. If you use a non-original charger, you may not be able to charge normally. Connect your phone directly to the wired charger to see if it can be charged. 4, according to your statement that it is estimated that the charging port is faulty and needs to be replaced, try a different line and the samePlug combinations, the same wire combinations as different plugs. 5, there may be the following reasons What is the meaning of charging protection board bm
The Samsung s8 doesWhat causes the simultaneous failure of wire charging and wireless charging?
6, if other mobile phones can normally wireless charging, wireless chargerYes, the mobile phone is faulty, please contact the local official after-sales service, by the after-sales help to solve.
