Wireless charging, while convenient, is significantly less efficient than wired charging, wasting more electricity and generating more heat. A study found that charging a smartphone wirelessly uses approximately 40% more energy than using a cable. This inefficiency, stemming from electromagnetic induction and an air gap between the charger and device, leads to substantial global energy waste when considering the billions of smartphones in use. The heat generated by wireless chargers can also degrade phone batteries over time and pose a fire hazard if safety mechanisms are inadequate or the charger is used improperly. AI
