回答“Power Issue with my Hauwei P9”Hi guys, I just had the same problem. I discovered that on the new battery, on the connector, two of the terminals had been short circuited from manufacture. Once I removed this short circuit it started charging. This would make sense it's the problem as likely one is in feed to the battery from the charging port, the other is feed to supply the phone from the battery. By short circuiting, when plugged in, the phone receives power, but the battery does not. It's on the charger now and going up, but I'll update if I remember in case I have any further problems.
