So the battery charges when its connected to a charger, the phone works fine until it hits 30% battery, and then dies? How many times has it done this?

Sound like an under voltage problem. Replace the battery the problem should be solved. Worked in 90%. You can also check your phone with iBackupBot. Read the Error logs. If you got low battery errors replace the battery.
