Made famous for its absurdity, the iPhone’s lack of a conveniently removable battery has been one of the iPhone and iPhone 3G’s harshest critiques. With the iPhone’s power-needs draining full batteries in as little as a day, the lack of a removable battery is made even more apparent. But, there’s hope yet. A new Apple patent application hints at future iPhone with a universal rechargeable battery – one that you can actually remove and replace on a whim!
The Apple patent application details plans for a universal rechargeable battery that can be swapped interchangeably between, presumably, Apple devices. In fact, one patent diagram depicts a mobile phone with a port for the universal battery pack. If Apple does have real plans to bring this particular patent to life, it’s not too far a stretch to see a future iPhone outfitted with the removable battery technology.
Apple’s patent for a universal rechargeable battery uses a Mac desktop as a central charging station for multiple universal batteries. The computer would feature charging-ports to manage and charge multiple batteries simultaneously. Batteries running low on juice would sent an alert to the computer, instructing the user to replace the battery with a charged battery.
