Recently the USB-C quick charger that came with my Huawei Nexus 6P appeared to stop working. I normally leave the phone charging over night, but one morning I found its battery charge was low and it hadn’t been charging. When I disconnected and reconnected it to the cable (which is reversible with USB-C connectors on both ends), the lightning bolt inside the battery charge indicator kept blinking (flashing on and off), rather than being solid on as it normally would while the device is charging.
Disconnecting and reconnecting the device or unplugging and reconnecting the charger to the wall socket made no difference whatsoever. Reversing the cable direction did not help either.
My only way to still charge the phone was to use a USB-A to USB-C cable that draws power from a PC USB socket, which is a much slower way to charge the phone. So I decided that the charger must have failed after less than a year of use. I already started looking for USB-C quick chargers on Amazon (they exist but are much more pricey than USB-A chargers), but didn’t order one yet.
Today I decided to Google for the problem and found others who had the exact same issue. It turned out that simply powering down the phone and powering it up again will fix the problem: Yepp, it will charge again!
I’m not sure what the fundamental issue is, but it seems I won’t have to rush out and buy a new charger (which wouldn’t have helped anyway!), as the issue is on the phone side.
If a simple phone reboot fixes it and it doesn’t happen too often, I guess I can live with that. The Nexus 6P has worked great for me so far.
