reason
< br >
1, did not use the original data cable, charger. The electricity rate is different, sometimes it can't be charged.
< br >
2, the charging port is blocked by debris, or damaged, resulting in slow charging or even no charging.
< br >
3. When charging, the system internal consumption is serious, that is, the mobile phone is used while charging, and the mobile phone system runs more software.
< br >
4, the battery is damaged, it is recommended to replace.
< br >
The charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment charging technology.

definition

Charger (charger) according to the design circuit working frequency, can be divided into power frequency machine and high frequency machine, power frequency machine is designed based on the traditional analog circuit principle, the internal power devices (such as transformers, inductors, capacitors, etc.) are larger, generally in the load larger operation there is less noise, but the model in the harsh grid environmental conditions in the resistance performance is strong, Reliability and stability are stronger than high-frequency machines.
A: There are many possible reasons why the charger is charged less and less, including the use of an unequipped charger, the mobile phone running a high power consumption program, poor charging port contact, and the battery aging failure capacity decline.
Among them, when charging with an unequipped charger or unofficial charger or data cable, the output voltage and power cannot reach the standard charging voltage and power, resulting in less and less charging
The phone's system is malfunctioning, which is causing problems with the battery level display. This problem is the easiest to solve, you can directly shut down and restart, which is equivalent to data refresh, and the general power display will return to normal.
The charger is faulty. This failure is the main reason why mobile phones cannot be charged. So how to judge the charger is good or bad. It's actually very simple, try another charger. If it can be charged, it can be concluded that the charger is faulty. This kind of problem, can only buy another charger.
