When you left the phone charging overnight, but it was not plugged properly
You're viewing a single thread.
The USB port on my phone is getting a bit tired and doesn't properly hang onto a USB cable anymore, so I'm mostly charging it wirelessly now. Which in some circumstances can be a bit of a problem but the phone still works.
Have you tried cleaning it? I had the same thing happening until I removed 1mm of dust at the bottom of my charging port
