Rumors about the iWatch keep coming in, despite the fact that Apple hasn’t so much as hinted if it is going to jump on the wearable device bandwagon in 2014. Last week it was rumored that perhaps iWatch will come with solar charging capabilities, it was also claimed that perhaps the battery would be charged by harnessing energy produced by the users’ swinging arm.
Contrary to recent news reports of solar-powered smart watches, Apple has confirmed that it will stick with lithium-ion batteries for its upcoming iWatch. These batteries are to be supplied mainly by Samsung SDI, LG Chem and Tianjin Lishen Battery, according to industry sources. This means the local manufacturers would be providing products for Samsung’s largest rival. “Apple will utilize LG Chem’s stepped battery since it offers better longevity than others and can be applied for different shapes,” a source said, declining to be identified. Stepped batteries consist of layers of batteries and are said to have around 16 percent more energy efficiency than a traditional battery, as the step-like design reduces unused space in the battery pack.
