I just had this problem with a Huawei Y536-A1. An ATT no contract phone. That I want to use for Android programming only, so haven't installed the SIM yet. Only about 45 at Walmart, its same size as Apple 5.

I just had this problem with a Huawei Y536-A1. An ATT no contract phone. That I want to use for Android programming only, so haven't installed the SIM yet. Only about $45 at Walmart, it's the same size as Apple 5, about 4.5 inches!. They may not have them anymore (I got it Aug 2015, what a deal !.)
It would not charge using a desktop USB port and mini-USB cord that works with other phones.

But the computer did recognize when it was plugged in, and enumerated it, with a beep, and
-

showed the memory in the phone.

So I pried off the back, starting at the USB jack end, and removed the battery for 10 secs, then put it back and replaced the back.

Now it wouldn't power up with its ON button. So I plugged it into the same USB mini cord again.

This time, it powered up and showed a large battery symbol,

and it was charging OK.

So I guess a hardware or software charging control got stuck.

I've had similar charging issues with lots of portable mini-USB devices like my Apple 5. Its often a bad driver in the desktop I guess.

Also- note - you have to plug the USB cord into the computer USB port in one push, once its centered and sliding in, not slowly, (assuming the other end is already in the phone- be delicate.).

This surge of current when it is plugged in fast, triggers the USB port to enumerate it.

Sometimes slowly plugging it in does not make the computer recognize it ! Believe it or not !

Sometimes slowly plugging it in does not allow the computer to recognize or charge it ! Believe it or not ! ... an engineer.
