I've bought an Axon 7 last month (A2017 Chinese variant 128gb internal 4gb RAM). One day when my phone was shut down, I inserted the usb type c into the phone's port to charge it and it vibrated and turned on and showed the battery and the percentage but it was not actually charging and the percentage didn't go up even 1% and as I waited longer it actually discharged 1%. I didn't have this issue before that day so I pulled out the usb type c and inserted it in again and I saw that it was charging normally.
Later I figured out that the reason of that issue was that I unintentionally inserted the usb type c in the port in two pushes.(I mean I inserted half of the usb type c first and then push the other half into the port) So I checked it out and I observed that when my phone is shut down and I insert usb type c in one fell swoop then my Axon 7 starts charging normally ,but when I insert half of it first and wait for just a second and then push the other half and all of it into the port, the phone vibrates and turns on and shows the battery percentage but doesn't go up even 1% and if I wait longer it will even discharge 1%. FYI I 've tried several chargers,quick chargers,cables and the one that came in the box but the results are the same so if it is a real issue,the issue is with the software itself. I hope you guys can help me with this and tell me the reason and if yours have got the same issue. I would sincerely appreciate any replies.(my Axon 7 is still running 6.0.1)
