Android 4.2 2 battery percentage remaining is wrong. How can I fix this?

[AC Question]

Android 4.2 2 battery percentage remaining is wrong.

My android 4.2 2 battery percentage remaining is 60%. I turn off cell phone. In half hour can not turn on. Battery drops to 0%. I made a factory reset. There has no third party apps. It happens many times. I couldn’t upload a snap shot about battery history details.

Welcome to Android Central! Which phone? The battery might be failing--can you try a different one?
