Google Maps is testing a power saving mode in its latest Android beta release that strips the navigation interface to its bare essentials. The feature transforms the screen into a monochrome display and removes nearly all UI elements during navigation, according to AndroidAuthority. Users discovered code strings in version 25.44.03.824313610 indicating the mode activates through the phone's physical power button rather than through any in-app menu. The stripped-down interface eliminates standard map labels and appears to omit even the name of the upcoming street where drivers need to turn. The mode supports walking, driving, and two-wheeler directions but currently cannot be used in landscape orientation.Read more of this story at Slashdot.
