Technology Joule Thief Circuit Reveals Hidden Energy Still Left in Dead Batteries
Rhett Allain of WIRED explains how a so-called joule thief circuit — a transformer paired with a transistor — can recover residual chemical energy from batteries that appear dead. The circuit can run a 3-volt LED on a single 1.5-volt AA battery, showing that battery depletion is not the same as zero energy.
Technology How Apple's iOS 27 Boosts Older iPhone Speed and Extends Device Longevity
Apple's upcoming iOS 27 update brings platform stability improvements that make older iPhones, including the iPhone 11 from 2019, run faster and more responsively. Key gains include up to 30% faster app launches, 80% faster AirDrop transfers, and 70% faster photo library loading, achieved through CPU scheduler optimizations. The move supports Apple's services business—which hit $31 billion in revenue—and reinforces brand loyalty, though older devices miss new Apple Intelligence features.
