The new and improved Cortana will also gain closer ties to Windows 10 Mobile phones and Android phones with Microsoft’s Cortana app installed. (Again, Microsoft hasn’t specifically said this will tie into the Windows 10 Anniversary Update, but it seems likely.)
In the future, Cortana will be able to pull notifications and low-battery warnings from your phone and beam them to your PC, cutting back on the need to pull your phone out of your pocket—and the threat of a dead device at the end of the day. The communication will go both ways, too, as you’ll be able to pull up Maps directions on your PC and push them over to your phone. Handy stuff.
