Apple looking at oddly shaped batteries, could improve phones’ battery life

Apple is thinking outside of the box. Or at least outside of the traditional box shape of a mobile device battery.

“This common type of battery pack design may be unable to utilize free space in the portable electronic device that is outside of a rectangular space reserved for the battery pack,” said a patent application from Apple that was made public this week by the U.S. Patent and Trademark Office. “For example, a rectangular battery pack of this type may be unable to efficiently utilize free space that is curved, rounded, and/or irregularly shaped.”

And with its recently released iPhone 7,  Apple appears to need some help with regard to the battery. Research firm Which found the iPhone 7 had the worst battery life in its class, because the battery was relatively small.

Apple’s patent application, made in February, envisions batteries in non-traditional shapes ranging from a rectangle with some areas removed to a “a spirally wound jelly roll” structure.

Although the technology is not guaranteed to reach the market, Apple may have hit on a way to boost battery life for its phones and other devices by leaving no internal corner unfilled.

    Apple started making irregular shape batteries for Macbooks last year which have excellent battery life compared to PC ultrabooks. Perhaps this battery technology will be used in iPhone 8?
