Bbeiii/Shutterstock The apps you actively use and have installed on your phone can be the primary reason your phone seems slow. That’s because apps use your device’s RAM and CPU to keep them running smoothly. So at some point, if you’re running a phone with really low RAM, like less than 8GB (8GB to 12GB is the sweet spot for RAM), and you’re using power- and data-hungry apps, you’re going to face problems. You can, of course, manage your cache, clear your storage,...

By Michael Kern – Mar 22, 2026, 12:00 PM CDT The core finding is that a quantum battery charges faster as it gets bigger due to a quantum effect called superextensivity, which is counterintuitive to conventional battery physics. Researchers have demonstrated the first complete charge-store-discharge cycle for a quantum battery, experimentally proving the fundamental physics works at room temperature. Despite its current limitation of only holding a charge for nanoseconds, the technology...
