Wave-particle duality, intertwining two inherently contradictory properties of quantum systems, remains one of the most conceptually profound aspects of quantum 

mechanics. By using the concept of energy capacity, the ability of a quantum system to store and extract energy, a device-independent uncertainty relation is

derived for wave-particle duality. This relation is shown to be independent of both the representation space and the measurement basis of the quantum system.

 Furthermore, it is experimentally validated that this wave-particle duality relation using a photon-based platform.
