Battery suddenly discharges
My battery suddenly (100% to 1% in 10 minutes) discharges with no Apps running. Then 100% is achieved after plugging it in, but way too fast to indicate proper charging time. How do I diagnose and solve this?

It sounds like your phone's battery has reached the end of its life. Does your phone work well when connected to an external power source? If so, it's probably worth saving. I would take it to a Genius Bar (make an appointment first) for a diagnosis, after which you can decide what to do. Good luck.
