Take a look at the react lifecycle.

You should implement a method called shouldComponentUpdate().

Use this as an opportunity to return false when you're certain that the transition to the new props and state will not require a component update.

This method will be called each time React thinks your component should update, if you don't want it to re-render under certain conditions, check for those conditions and then return false in this function.
