You should use static when:
- The code in the method is not dependent on instance creation and is not using any instance variable.
- A particular piece of code is to be shared by all the instance methods.
- The definition of the method should not be changed or overridden.
- You are writing utility classes which should not be changed.

Well in general static means it's out of the context of an object, so you usually use it for definitive functionality that doesn't depend on a state.
Like in Factory design pattern, instead of creating an object, you use a method from a static class that returns a new object for you.
