Built-in inductive charging

Right now, if you want to charge your phone's battery using inductive "wireless" charging, you have to buy a separate charging sleeve (case) and charging mat for your device.

Companies like Powermat and Energizer make inductive charging products for a variety of smartphones. However, if you could do away with the sleeve and have the inductive-charging chip built into the phone, you'd only have to buy a mat (and you could use whatever case you wanted to use).

Qi (pronounced chee), a new standard for inductive charging as established by the Wireless Power Consortium (WPC), is pushing to get manufacturers to integrate Qi chips into their devices, and we've been waiting for Qi-enabled smartphones to hit the market (a few, including the Nokia Lumia 920, offer wireless charging). No such luck with the iPhone 5, but at some point in the future we think the iPhone will get some sort of inductive-charging chip integrated into it.

Chances of implementation: 10 percent
