Phones, tablets and other devices slow down over time, no matter how expensive or cutting edge they were when you bought them. Now, researchers from Hanyang University in Korea claim a technology they developed can delay the inevitable. It's called Where's WALDIO or Write Ahead Logging Direct IO, and according to team leader Professor You-jip Won, it's a mode that extends battery life and speeds up phones by minimizing the amount of data a device records. "The core of the newly-developed technology is to record a small amount of data," Won said. "This tech will make it possible to use low-priced flash memory for a long time, like expensive flash memory."
