Do you think there could be any disadvantages to wireless charging? If so, what could they
be?

LOTS

Explanation:

Not exactly wireless. When people hear the term wireless, they immediately think that they can move around pretty freely ...

You aren’t able to use your phone. See above. The phone needs to stay on the pad in order to continue charging.

Slower charging. The efficiency of Qi charging is still lower than cable charging, so it takes more time to charge wirelessly using the same amount of power.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
