Abstract: A portable electronic device determines a battery available power for the device's battery and manages device power usage based upon the battery available power. The device includes a battery and a controller. The controller is configured to receive a first voltage value for the battery at a first time, a first current value for the battery, a second voltage value for the battery at a second time, and a second current value for the battery. It is determined that a time difference between the first time and the second time exceeds a predetermined time threshold. An estimated resistance of the battery is determined based at least on a first difference between the first current value and the second current value and a second difference between the first voltage value and the second voltage value. Real-time power usage of the device is controlled based on the estimated resistance of the battery.

Abstract: Systems, methods, and computer-readable media are disclosed for improved wireless battery charging. The device may include a battery, and may be configured to determine that the battery is de-coupled from a wireless charger at a first time, determine that the battery is coupled to the wireless charger at a second time, determine that a first elapsed time between the first time and the second time is equal to or less than a first threshold, and cause charging of the battery to be disabled for a first time duration.

Abstract: A first device in a system produces a first clock signal, while a second device in the system produces a second clock signal. A clock arbitration component of the system determines which of the clock signals to send to a third device in the system, which generates data based on the first clock. This data, along with data from the first device, is used to generate synchronized data, that is synchronized based on the first clock, which is then sent to the second device for performance of a function. At times when the first device is not active and only the second clock signal is received, the second clock signal is sent to the third device, which generates data based on the second clock that is used to generate synchronized data to be sent to the second device.

Abstract: Apparatuses and systems for conserving power for a portable electronic device that monitors local audio for a wakeword are described herein. In a non-limiting embodiment, a portable electronic device may have two-phases. The first phase may be a first circuit that stores an audio input while determining whether human speech is present in the audio input. The second phase may be a second circuit that activates when the first circuit determines that human speech is present in the audio input. The second circuit may receive the audio input from the first circuit, store the audio input, and determine whether a wakeword is present within the audio input.

Abstract: This disclosure describes, in part, techniques for performing multi-path calculations for energy levels on an electronic device. For instance, the electronic device may include a first circuit and a second circuit, where the first circuit uses less power than the second circuit. As such, when operating in a standby mode, the electronic device may use the first circuit to calculate energy levels at the electronic device, such as speech-energy values and ambient-energy values. Additionally, while operating in an active mode, the electronic device may active the second circuit and then use the second circuit to calculate the energy levels at the electronic device. The first circuit and the second circuit can send/receive current energy levels between one another so that the electronic device can continually calculate the energy levels even when the electronic device switches between modes of operation.
