It was reported this morning that, according to Bloomberg sources, the “iWatch” will be landing this year. Sources for The Verge have corroborated these claims, but they have also offered a few more things to the discussion, including battery life concerns.

Apple Senior Vice President of industrial design Jony Ive is heading the wristwatch project with around 100 others below him.

Interestingly, the team has decided to rework stock iOS to work with the purported watch, rather than rebuild the proprietary version seen on Apple’s current generation iPod nano. The last generation of the iPod nano was already watch sized, and it’s worth noting that Ive has decided to seemingly ditch what was already a pretty efficient touch OS. The same happened with the iPhone when Apple decided to rebuild Mac OS X rather than try to rework what was a weak iPod OS.

Sources for The Verge say that the biggest problem Apple is currently facing with the watch is battery life. “The goal is [for the device] to last at least 4-5 days between charges, but the current watch prototypes are only going for a couple days max,” the sources say.

Luckily for Apple, new battery tech is constantly being researched, with new devlopements from the University of Southern California demonstrating a battery that can “hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes.” The tech may not make it into this years “iWatch,” but I have high hopes for battery tech in 2013. Like with most Apple products, it’s probably best to wait for next year’s model.
