I forgot to charge my ROG phone 5 yesterday and the battery drained itself to 9% so I leave it to charge the entire morning, just to find that it stayed at 5% afterward. When I plug it in, it just shows the charging indicator for a brief second and then nothing, like the phone isn’t plugged in.The phone came with its own 60W charging brick and cable and never failed once before today.I tried to troubleshoot it with an Anker power bank and a lower wattage charger from my old phone. When I try to charge with the lower wattage charger, it works (although obviously slower). It also works when I charge it with the power bank but with the cable from the lower wattage charger. I then tried to charge it with the power bank but with the USB type C to C cable from Asus and it didn’t work.I was going to conclude that my official Asus charging cable is the problem but it worked fine when I try to charge the power bank with both Asus charging brick and cable.
It fixed itself! After charging to nearly full with the low wattage charger, the official charger worked normally again!
