Report: iWatch to use LG stepped battery tech

Updated

Apple will use stepped lithium-ion batteries in its upcoming iWatch, according to a report from The Korea Herald. The batteries will be supplied by LG Chem, Samsung SDI, and Tianjin Lishen Battery, sources said. As the report notes, a stepped battery uses layers of batteries to offer more energy efficiency in a footprint similar to a regular battery. The report also suggests the iWatch is “unlikely to sport a curved screen.” LG Chem announced production of stepped batteries and curved batteries last year. LG’s G2 phone uses a step design to increase capacity in a small space.

A recent report suggested Apple was experimenting with magnetic induction charging for the iWatch, as well as new battery technologies, including solar charging, and kinetic charging — though that report noted some of the methods were “years” from happening. An Apple patent application from July revealed a flexible battery pack, while an early iWatch report said Apple was hoping battery life for the device could reach four to five days.
