Abstract

Disclosed herein are systems and methods for charging batteries of audio playback devices. An example method performed by a media playback system includes receiving power from a first power source to charge a first power storage of a first playback device according to a first charging scheme, and receiving power from a second power source to charge a second power storage of a second playback device according to a second charging scheme. The system receives an instruction to form a group for synchronous audio playback, and obtains one or more power parameters associated with the first playback device and/or the second playback device. After receiving the instruction to form the group, the system modifies the first charging scheme based on the one or more power parameters, and then receives power from the first power source to charge the first power storage according to the modified first charging scheme.
