  • Techniques for conserving power on a device
    Patent number: 12257496
    Abstract: This disclosure describes, in part, techniques for conserving power on an electronic device. For instance, at given time intervals, the electronic device may be sending input data to a network device and receiving audio data from the network device. The electronic device may then use one or more techniques to determine when to switch from operating in a first mode, where the electronic device sends and/or receives the data, to operating in a second mode, where the electronic device ceases sending and/or receiving the data. For example, the electronic device may make the determination based on an amount of data stored in a buffer, whether the electronic device receives data, using data received from the network device, and/or the like. Based on the determination, the electronic device may switch to the second mode in order to conserve power.
