My phone died last night while I was out and when I plugged it in this morning the infrared light came on and has been on ever since. It is glowing bright red brighter than it would be during a phone call and won't turn off. It's causing that area of the phone to be extra warm and killing my battery. I had my phone charging for like 4 hours and it only made it to 50%. Does anyone have any clue as to why this might happen?
