Engineers at Northwestern University are creating batteries that last longer and charge faster, a potential solution to battery drain on mobile devices. Using the innovation, a typical smartphone is expected to charge fully in 15 minutes and last for at least a week on a single charge.
As consumers use smartphones and tablets for more data-intensive purposes like watching movies, playing games and surfing the web, battery life has become a big concern. Apple just completed software updates on its iPhone 4S to fix battery drain problems, and researchers are always on the lookout for ways to make batteries last longer or charge more efficiently. Hopefully, battery life will become stronger and quicker to charge as technology grows making it all the more convenient to operate portable electronics.
