Wireless charging can be slowed, interrupted or prevented by an unsuitable phone case, even though cases remain important protection as handsets become more expensive. The article advises choosing cases designed to work with induction charging, particularly where magnetic alignment systems such as Qi2 or MagSafe are used.

Thick cases make power transfer less efficient and can trap heat, while metal components or poorly positioned magnets may block charging altogether. Wireless charging is inherently slower and less efficient than wired charging, with current top speeds of 25W versus 80W or more for some wired systems; accessories such as grips and PopSockets can add further bulk and heat risks.
