The phone shows charging, but can not be charged, indicating that the charger, charging interface, battery or cell phone motherboard and other aspects of possible problems, need to be investigated one by one to solve the problem.


1, the charger output power is too low to meet the charging needs.

After the charger is connected to the phone, the current it provides not only needs to charge the battery, but also needs to maintain the normal operation of the phone. If the power output of the charger is too low, that is, the output current is too small, it will directly affect the charging efficiency. In this case, the phone charging will appear to have a prompt, but can not charge the phenomenon occurs.

At this point we can try to replace the maximum power or quality charger, and then try again.



2, the charging interface is oxidized by liquid corrosion, the resistance becomes large.

Cell phone charging interface is usually located on the bottom of the screen on the small plate, part of its structure directly exposed in the air, if long-term charging in a humid environment or improper operation to make it into the liquid, it will lead to the interface in the gold finger is corroded and oxidized.

The normal gold finger is generally golden yellow, after oxidation its color will become green or black, which will increase the resistance of the charging interface, so that the current through it becomes smaller, and therefore affect the actual charging effect.

For this problem, only by replacing the charging interface or charging board to solve.



3, charging IC damage.

Cell phone charging work is usually in charge of the charging IC, this function chip or integrated in the power IC, or independent of the battery interface. If this component is damaged, it may lead to the phone does not charge, charging can not be charged and other phenomena occur.

If this is the problem, then it requires maintenance personnel to use professional equipment on the motherboard for testing and repair, so here it is not recommended for this problem to dismantle their own machines to avoid causing greater failure.



4, the battery is seriously aged or damaged.

Smartphone batteries are generally composed of cells, protection plates and connectors, if the battery is seriously aged or damaged protection plates, it is possible to trigger the phenomenon of battery discharge without charging.

Of course, the chances of this is relatively low, if the first three points have been ruled out, then this time you can solve the problem by replacing the new battery.
