Well, my problems in this regards are as follows.
Until today I didn't realize the connection between Nougat and My N6P charging problems, I'm in the beta program so my problems began like a month ago or so.
First I realized that sometimes my phone wouldn't charge when connected to the wall charger, I almost never charge with another method different than this. Of course my first instinct was to check the USB-C cable, it charged just fine but the issue appears again, change the cable and everything worked like a charm, then obviously the problem returned.
At that point I chatted with Huawei support, I was wondering if they're could replace the charger, they're told me that for that I must send the old one to them, but I declined.
Anyways, I was chatting with Miles S and he told me that he has a trick that works. The trick was to leave the power button press for exactly 30 seconds, then connect the power and press the power button for 30 seconds more, I did it and it works, but as expected the problem returned the next day.
So I went to Amazon and bought a new charger, arrived and worked like a charm the first time, the second time the charger wasn't even recognize. The same of course happened to the one that came with the phone too. At that point I realized something, this only ocurrs when you are using a USB-C charger, I haven't had a single problem when using an USB 2.0 with an USB-C Adapter.
I went to google and there are a lot of people with this problems. I was thinking about to send my phone for warranty but I don't have a second phone and as I don't know if I would receive a new device, instead of a refurbished one as when you buy from Google Store, I will wait.
Hope this help someone
