An Apple patent filing filed today suggests that Apple may be working on a way to make its long-rumored iWatch slimmer than existing offerings by reducing the size of the battery required.
One of the barriers to widespread adoption of smartwatches is that existing models are not exactly sleek. Technology lovers might be willing to put function ahead of form and put up with chunky devices, but the wider market buys on style first, technology second.
While the Bluetooth LE protocol used by existing smartwatches uses around half the power of classic Bluetooth (peaking at 15mA instead of 30mA), a constant connection in a device you won’t want to charge daily still requires a reasonably chunky battery.

Shortly after an Apple patent for a flexible battery design suitable for the rumored iWatch was published, German site MobileGeeks has shown off a real-life example of a fully-flexible, watchstrap-sized battery from Taiwanese company ProLogium.

The patent shown by Apple still appeared to show rigid batteries mounted on an FCP. FCP Ceramic Lithium Batteries are the latest version of this technology, allowing the batteries themselves to be flexible. A quick video look after the break:
