Nexus 5, cup of tea and red light of death topic

Sister-in-law dropped her Nexus 5 into a mug of tea. Almost completely submerged. Only the USB port was sticking out. Red light of death appeared. Phone was put in a bowl of rice and eventually put in the hot press. Still had the red light of death. Tried charging it. Red light of death was constantly on and no sign of life. Today, 3 or 4 days after the accident, I took the back off, unscrewed the battery connection and pulled it off then fitted it back on. Held the power button on for four seconds as per normal and the phone turned on and is working 100%. Hope this helps other Muppets who drop their phones in a mug of tea lol
