1. A playback device comprising:
at least one communication interface;
one or more amplifiers configured to drive one or more audio transducers;
a battery configured to power the playback device;
at least one processor;
at least one non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the playback device is configured to:
while in a first mode of operation and connected to at least one data network, (i) maintain network information corresponding to one or more devices on the at least one data network, and (ii) after receipt of audio content via the at least one data network, play back the audio content in synchrony with another playback device using the one or more amplifiers;
transmit at least one message comprising an indication that the playback device is to transition from the first mode of operation to a second mode of operation where the playback device consumes less power than in the first mode of operation;
transition from the first mode of operation to the second mode of operation;
while in the second mode of operation, (i) forego maintenance of the network information in a network table, and (ii) detect receipt of at least one wake message;
after receipt of the at least one wake message, transition from the second mode of operation to the first mode of operation; and
after the transition from the second mode of operation to the first mode of operation, update the network information corresponding to the one or more devices on the at least one data network.
