OKay, so I had the same problems. I let my phone go all the way to 0%. Boom, its dead and i assume that i could just charge it like any other time. My phone's LED light blinks red for 1 second when i put the charger into the port. I look at the screen and the phone is not charging. I tried using the USB cable for my cheap smartphone and it charges that phone very slowly. I also tried rebooting my phone with the power button and volume bottom, but it just literally uses up the rest of the battery. So i decided to buy a new and cheap USB cable from Amazon and yo, it literally revived my phone. It went from 1% to 11%. Hopefully it works for you.
