MacBook Pro CPU usage reaches 100% when battery reaches 68%.

I have observed that MacBook Pro CPU usage reaches 100% and slows down when battery reaches 68%. When I connect to power CPU works fine at average 4% usage.

I do not see any issue with Battery it lasts around 9-12 hrs in normal usage. I tried resetting SMC but no luck.

Can anyone please let me know how to fix it.

MacBook Pro 13", macOS 10.12
