Insight summary

Wireless charging technology is transforming the way we power our devices, from smartphones to electric vehicles. The shift towards wireless charging is driving new opportunities in product design, public infrastructure, and business models, as well as influencing government regulations and environmental considerations. As this technology continues to evolve, it promises to reshape our daily lives, offering more convenience, fostering sustainable consumption patterns, and opening new avenues for innovation and competition.

Wireless device charging context

Wireless device charging became increasingly important to large digital device and electronics manufacturers during the 2010s as they sought to improve conventional charging systems. This improvement was driven by the growing demand for more convenient and efficient ways to power devices. The shift towards wireless charging also reflected a broader trend in technology towards seamless integration and user-friendly design. By eliminating the need for cords and plugs, manufacturers were able to offer a more streamlined and aesthetically pleasing charging experience.

Wireless device charging involves charging an electronic device without a plug and cable. Previously, most wireless charging devices resembled a special surface or pad, with the device (often a smartphone) placed on the surface to charge it. Smartphones from most major manufacturers have in-built wireless charging receivers, while others may need a separate receiver or adapter for compatibility. This trend has extended to other devices as well, such as smartwatches and tablets, reflecting a broader shift in consumer electronics towards more convenient charging solutions.

Wireless device charging works through a process known as electromagnetic induction. A copper induction coil is placed inside the device and is referred to as the receiver. The wireless charger contains a copper transmitter coil. The device is placed on the charger during a wireless charging period, and the copper transmitter coil creates an electromagnetic field that the copper induction coil converts to electricity. This method of charging is not only convenient but also safe, as it minimizes the risk of electric shock. It also allows for more flexibility in device design, as manufacturers no longer need to include a specific port for charging, leading to sleeker and more versatile products.

Disruptive impact

The integration of wireless charging systems into smartphones and smart devices has continued to accelerate, and consumers have widely accepted this technology. Research is ongoing to improve the technology, and presently, the largest wireless charging standard, such as "Qi," is used by leading smartphone manufacturers including Samsung and Apple. The growing adoption of this technology may drive its further acceptance among consumers, leading to increased manufacturer competition. This competition could result in more affordable and efficient wireless charging solutions, making them accessible to a broader range of consumers.

Several companies are working towards making wireless device charging possible over several meters. For example, Xiaomi announced in January 2021 that its wireless charging system, Mi Air Charging Technology, was capable of working within a radius of several meters. Moreover, the wireless charger can charge multiple devices at 5 watts each simultaneously. This development has the potential to transform not only personal device charging but also public charging stations, such as in airports or cafes. This feature could lead to more flexible and convenient charging solutions in public spaces, offices, and homes.

For businesses, the widespread adoption of wireless charging may lead to new opportunities in product design and service offerings. Hotels, restaurants, and transportation services may integrate wireless charging into their facilities, enhancing customer experience. Governments and urban planners may also consider incorporating wireless charging infrastructure into public spaces and transportation systems. This trend can contribute to the development of smart cities, where technology is seamlessly integrated into the daily lives of citizens, fostering a more connected and efficient urban environment.

Implications of wireless device charging 

Wider implications of wireless device charging may include:

• The widespread adoption of wireless charging technology leading to a reduction in the production and disposal of charging cables, contributing to less electronic waste and a more sustainable consumption pattern.


• Increased investment in wireless charging research and development by companies, leading to job creation in the fields of engineering, design, and manufacturing.


• The development of wireless charging infrastructure in public spaces, such as parks and bus stops, enhancing accessibility and convenience for citizens and potentially influencing urban planning and design.


• The integration of wireless charging in vehicles, public transportation, and highways, leading to new possibilities for electric vehicle charging and supporting the shift towards cleaner transportation options.


• The emergence of new business models for cafes, restaurants, and public venues that offer wireless charging as a value-added service, leading to potential revenue streams and enhanced customer experiences.


• Potential health and safety regulations by governments to ensure that long-distance wireless charging technologies meet specific standards, leading to increased oversight and consumer protection.


• The possibility of energy inefficiency in some wireless charging technologies, leading to increased energy consumption and potential environmental concerns that may need to be addressed through regulation and technological advancement.


• The democratization of wireless charging technology, leading to its availability in developing regions and potentially bridging technological gaps, enhancing connectivity and access to modern amenities.


• The potential for wireless charging to become a standard feature in household appliances and furniture, leading to a shift in interior design and home living experiences.


• The risk of market monopolization by a few leading manufacturers controlling key wireless charging standards, leading to potential challenges in market competition, pricing, and consumer choice.

Questions to consider

• Do you think wireless device charging would expose users to harmful electromagnetic radiation?


• Do you think battery technology will develop to the degree where batteries won’t be negatively affected by wireless phone charging compared to charging a battery using a cable?
