Why did the mobile phone charge quickly before, but now it charges slowly? Tell me what happened.

Check whether it is because the charging plug and charging cable are aging, and see if it can be solved after replacement; Check whether the charging environment is overheated; Or there is a foreign body inserted in the tail of your mobile phone, which leads to poor contact of the data port. Specifically:

1, charging plug, defective charging plug is easy to lead to slow charging. When we charge the mobile phone, please try to use the original charging head. Some inferior third-party charging heads may cause abnormal charging due to voltage and other problems. If you find that charging is slow, you can borrow someone else's original cable and try again.

2, charging cable, although the USB cable on the market looks the same, but the current they support is not exactly the same. If the charging is slow, change an original data cable first and try again;

3, charging temperature In fact, the temperature also has a certain impact on the charging speed. In the low temperature environment, the low temperature protection mechanism of lithium battery will start, which will lead to the inability to charge or the slow charging speed; In a warm environment, lithium batteries can work well. Of course, the hotter the better, the overheated environment will lead to battery scrap;

4. Plug the tail into the ash. If the above three points are all right, then you may need to check whether the dust blocks the charging tail. This is a detail that we easily overlook. At this time, you only need a paper clip or toothpick to slowly hook out the dust or dirt.
