Charger not working, replaced battery and charger port.
My ZTE ZMax Pro Z981 would only flash the white light while charging. But after a few hrs of charge, the screen would come on saying battery was empty. Please allow phone to charge a few minuted before powering on. And had a red bar in the battery. After a bit the battery critically low warning would come on the bar would be orange then would begin to charge. It would only make it to 3% then it would stop charging. Powering it on it would come on at 1% then die. I thought it do to the battery so I had an old zmax pro with broken screen swapped the battery and the port, phone come right on when the phone died it did as it did before going right to red battery then orange then 1-3% and would not charge. Hard reset. Wiped cache. Still the same. Please help.
