Presently, wireless charging is not faster than wired charging. For example, a 5W wireless charger will take about 4 hours to fully charge your phone while a wired charger will do the job within 2 ½ hours. The majority of newer models of wireless chargers come with fast-charging technology but this does not make them faster than wired chargers.
If phone manufacturers update their operating systems, it may boost their wireless charging speed. However, the speed will still be dependent on several parameters like air temperature, age of the phone and battery, the phone’s battery level when set to charge, and so on.
