Apple has secured Simplo Technology Co. and Dynapack International Technology Corp. to supply battery packs for the vendor’s upcoming iPad 3 tablet, Taiwan Economic News reported on Tuesday. According to the report, the new batteries will be thinner and lighter than the modules used in Apple’s current iPad 2 models, and Apple’s cost for the power packs will apparently jump by between 20% and 30% as a result. The report also states that Apple’s new iPad 3 batteries will feature a longer service life than the previous-generation packs used in the iPad 2. A thinner, lighter battery could mean Apple is conserving space for a new beefier Retina Display, or it could mean Apple is slimming down the iPad 3 case from the iPad 2’s already-svelte 0.34-inch-thick profile. Apple is expected to launch the iPad 3 early next year.
