We’re all used to it now but when the iPhone first debuted, a common criticism leveled against it was battery life. Apple’s always been aggressive with power management across its iOS devices, but compared to the feature phones that were nearly ubiquitous at the time, the iPhone is a hog, and users buying one had to switch from charging their phones once every few days to charging it one or more times per day.
Apple’s only improved the battery life of the iPhone since then, but as our gadgets become ever more power hungry, there’s always going to be an increasing demand upon lithium-ion tech. In a new patent, Cupertino seems to have identified a new way to improve battery life, and while it’s hardly as esoteric as Apple’s more wild-eyed patents, it’s plenty exciting for those who want a longer lasting iPhone or MacBook.
