So this has happened a few times to my phone now. I've forgotten to charge it for a few days and then when I plug the cable in, this small red LED type light appears at the lower end of the phone. I fixed it the first time by holding both the power and volume buttons simultaneously and then plugging the power cable in. It takes a few attempts, but the whole startup thing happens and the phone starts charging normally again.
Has anyone got any experience/knowledge of this or has anyone got a permanent solution to this issue? I don't really want to have to do this every time my phone runs out of power so any advice would be greatly appreciated
