How to Fix My iPhone 4 from Shutting Down Automatically Even It's Not Drained Yet?

My iphone 4 always shuts down even it is not yet drained. And if I plug the charger, charging works but the Drained Battery Sign still showed and if I remove the charger, it's still battery drained. Sometimes, my iphone turns on but I need to force turning on, and few minutes it will shut down again even it's still 100% charged. How to fix this? Please? Thank you so much. I'm just worrying.

You might have a bad battery. Should probably take it into Apple so they can run a diagnostics on it. It could also be a software issue (this thread has many supposed fixes, but the success varies greatly).
