This bit of detail might still be under the rumor category, considering The Verge cited unnamed sources who claim to be familiar with the iWatch prototype hardware. According to said sources, the existing test models manage to achieve approximately two days’ worth of use, max, prior to a recharge. What do you think of having to recharge your watch once every 4 to 5 days? Well, I am quite sure that prototypes are just that, and there are still plenty more refinements to be done before the iWatch is ready for public use, in addition to optimization of the software which will surely go some way in prolonging the battery life to bring it closer to the customer guesstimates.
