Possible reasons why iPad is not charging
Generally speaking, when the iPad is charged with a cable, an icon like "green battery with lightning in the center" appears. This has also become important for many iPhone and iPad users to judge whether their device is charging or not.
Many people should have this question, why the charging icon will be displayed when the iPhone is connected to the computer using the cable, but the iPad will instantly display the charging icon, and then again what about return to uncharge?
In fact, the reason is very simple. The USB of a computer uses 500mA of power supply. For the iPhone, this is enough for the device to determine that it is charging.
However, for the iPad, the power supply speed is so slow that its system thinks it is not charging status.
However, our iPad can still be charged! It's just really slow and slow. Let's take a look at the results of my test below.
My test
In the morning.
However, is this the end? Actually it won't.
I ran to develop the program for a while, and was tortured by BUG and my stupidity for a while. I really forgot the exact time.
But I came back to see the iPad and unplugged the charging cable.
It can be seen that the power has increased from 78% to 82%. Although it is slow, it is not impossible to charge.
However, it is recommended that everyone use the socket to charge it.
