My battery is showing 100% charge even after heavy usage.

[AC Question]

I have Lenovo A7000, it is approximately a year old. Since the last 2 days, the battery indicator is showing 100% charge...even after heavy usage. After this incident started, I have been charging my mobile at regular intervals to avoid it from shutting down suddenly. Please help me fix it.
