Boy Genius Report features a story from the Taiwan Economic News today which says that Apple has enlisted Simplo Technology and Dynapack International Technology to make the battery packs for the iPad 3. Apparently these new batteries that will be made by these two new companies will be “thinner and lighter” than those in the iPad 2, according to the Taiwan Economic News’ sources, and because of this, the battery packs’ costs will rise to between 20% and 30%. However, despite being thinner and lighter, the batteries will also last longer than those in the iPad 2, although there are no specific details revealed about how much longer, as yet. Quite what the extra space created by these smaller batteries could mean is open to speculation; it could mean that Apple plans to make the iPad 3 even thinner overall than the iPad 2, or maybe it needs more room inside to accommodate some new element, such as a Retina screen, for example.
