We really don’t require separate charger & its cord.
What we need is an efficient, dedicated “USB to Power Adapter” for mobile. (A)
We can charge any mobile through its existing USB connection cord, which is generally used for file sharing, transfer with desktop/laptop.
Mobile manufacturers can sell this Adapter as an accessory & you just purchase it once.

Even… USB can become part of the mobile…
Folded USB (B) could rotate out for connection (no cord)
Winding cord USB(C) can be pulled out whenever it is required. (New ideas to add extra mass to ultra thin mobile )

With reference to
“Morning Edition, July 1, 2009 • The European Union has reached an agreement with all major mobile phone manufacturers to produce a common phone charger. Apart from reducing the frustration of customers juggling incompatible chargers, proponents say the agreement will encourage recycling and reduce electronic waste”
