Why you don’t want to wirelessly charge your smartphone

Why not?

1. it's inefficient

2. harms the battery – part of that inefficiency is due to the receiving aerial in the phone getting hot – which heats the battery – which shortens its life

3. positioning is critical – differences of less than a centimetre (0.4 inch) can substantially reduce the charging current

4. slower

5. more expensive
