I have the galaxy note 5 and i got it like 4 months ago so its not old. About a week ago, everytime i plug in my phone it says "device charging slow". My phone was at 9% and i plugged it in and left it alone for an hour and it only went up to 10%. I am using the original cable that came with my phone. My brightness isnt high. Im not on wifi or Bluetooth. I have no idea what the problem is. Can someone help me?
