Some new high-end smartphones, including the Nokia 920, Google Nexus 4 and HTC Windows Phone 8X, have built-in wireless charging. Rumor has it the Galaxy S IV will too. Samsung is a member of the Wireless Power Consortium, and it's a safe bet that its cordless charger will adhere to the group's Qi inductive power standard.
Not only does wireless charging make sense for a high-end smartphone, it also has the potential of spurring aftermarket sales of profitable power-charging doodads. And from a marketing perspective, wireless charging might give Samsung more iPhone-bashing ammunition for its next round of TV ads -- assuming, of course, the next-gen iPhone lacks a similar (or superior) feature.
