An electronic device can include a power system including a battery and a processor programmed to: receive synchronized context data from one or more other devices associated with a user of the device, determine, at least in part based on the synchronized context data, one or more battery charging intervals, and operate the power system to charge the battery from the external power source during the identified one or more battery charging intervals. The processor can be programmed to determine the one or more battery charging intervals using a machine learning model. The synchronized context data can provide indication of the user's location. If the synchronized context data indicates that the user is at a different location than the device, the one or more battery charging intervals determined based at least in part on an expected time for the user to return to the location of the device.

Presented herein are techniques for initiating a night-time mode of operation in an implantable hearing prosthesis in response to detection of night-time recharging operations. More specifically, an implantable hearing prosthesis comprises a rechargeable battery that is configured to be recharged via an external night-time charging device, such as a pillow charger. The implantable hearing prosthesis is configured to detect inductive charging of the rechargeable battery by the external night-time charging device. In response, the implantable hearing prosthesis is switched to a night-time mode of operation.

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.

Systems and methods are disclosed for prioritizing vehicle charging using energy from renewable/low carbon emission energy sources over non-renewable/high carbon emission energy sources. The proposed systems and methods allow users to identify when to charge their vehicles and/or when to provide energy from their vehicles to other structures based on a currently available energy source mixture and in a manner that minimizes the impact to the environment. In-vehicle connectivity may be utilized to obtain real-time grid information, and a charging schedule may then be created that intelligently prioritizes charging during times when an energy mixture percentage available from renewable/low carbon emission sources exceeds a predefine threshold or when a real-time emissions level is below a predefined threshold.
