iOS 5, the next version of Apple’s mobile operating system, will include a built-in feature that warns Japanese citizens of impending earthquakes.
It works by connecting to Japan’s nationwide earthquake warning system that has been in place since 2007, 9 to 5 Mac reports. Users would receive a push notification seconds to minutes before an earthquake occurs.
Using the feature takes a hit on your battery life, says the text below the blue on/off slider, because your phone stays connected 24/7 with the earthquake notification system.
Check out a screenshot below of the new setting found in iOS 5’s Notification centre:
