"Free" as a word has the ability to get consumer attention instantly. While retail stores usually adopt this sales technique to boost sales, manufacturers are also not behind. For innovative companies pioneering in a field in which others fear to tread, free as a tool can be used to gain and retain competitive advantage against others.

In 2015 Samsung's smartphone arsenal comprising of the Galaxy S6, Galaxy S6 edge, Galaxy S6 edge+, and Galaxy Note 5 is gaining eminence for wireless charging capabilities. Samsung played a masterstroke by incorporating wireless charging in the Galaxy S6 and S6 edge earlier this year, but the Korean giant took the game to another level by making wireless charging faster in the Galaxy S6 edge+ and the Galaxy Note 5. This resulted in faster charging times and in turn it would compel customers to adapt wireless charging as a necessary part of their lives.

Right now the only competitor to wireless charging is the USB Type-C technology which is available in flagship phones like Onplus 2, Nexus 6p. One problem with this new technology is the replacement cost, when USB Type-C cable gets damaged. If this gets accepted as a mainstream accessory, wireless charging will be left for the "early adopter". But, we consider that wireless charging is a better technology, as it saves the phone battery from mild electric shock whenever it is plugged in and thereby elongating the battery life.

In order to drive adoption and make wireless charging the de-facto technology of charging phones, Samsung can give away wireless charger as a necessary accessory in the high-end smartphones scheduled for release in the future.
