Look at the cable on the microUSB back side, you'll see two pins popping out a little. Issue i had with that cable is while i tried to put the connector in the right position (it was bended) i pushed in the wrong side and those pins where not popping out anymore..
Which is a problem since they help phone to detect while you connect & disconnect cable, maybe more. I tried to make the pins pop out using a needle. Worked for some time, until days ago. While trying to fix, i realised that these pins will actually pop in/out depending on how you bend the connector.
So i bended it to make them pop out just as if brand new. Problem is now, even though the phone detects (and hold tight) the cable/AC power, the phone won't charge. Just like if no power was coming it. I tried various things, but it won't change. This cable is much longer/better than others, hope i can fix it..
