"Moreover, the default mode for the shifters and derailleurs is 'sleep'. A button push instantly 'wakes up' each shifter's transmitter, and that signal correspondingly activates the uniquely paired receiver.
SRAM's patent documentation doesn't outline specifics in terms of run time but it does claim a power draw that's just one-tenth of a wireless system that's always on. The automatic sleep mode means users won't have to manually shut things down, either, as is required for Campagnolo EPS."
