Embodiments disclosed herein relate to reducing power consumption of an electronic device scanning for wireless communication signals while maintaining or even improving an efficiency of the scanning operations. To do so, the electronic device may include more than one scan core, such as a main core and a receiving core. The receiving core may have limited functionality compared to the main core. For example, the receiving core may only receive wireless signals (including scanning for wireless signals). That is, the receiving core may not support certain operations that consume relative high power that are supported by the main core, such as transmission of signals. In this way, operation of the receiving core, either in place of or in addition to the main core, may reduce power consumption of the electronic device by avoiding high power consuming operations, such as data transmission, while scanning for various signals.

Power management for signal scanning

Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

OLED display power modeling

Apparatus and methods for configuring wireless circuitry of a wireless device to optimize power consumption based on operating states of the wireless device are disclosed. When associating with or while associated with a multiple-input multiple-output (MIMO) capable wireless local area network (WLAN) access point (AP), the wireless device configures the wireless circuitry to use a MIMO mode that includes at least two spatial streams for communication with multiple radio frequency (RF) receive chains active, a single-input single-output (SISO) mode or a multiple-input single-output (MISO) mode that includes only one spatial stream and a single RF receive chain active, or a single-input multiple-output (SIMO) mode that includes only one spatial stream and multiple RF receive chains active, based on balancing application requirements for data throughput with power saving modes to conserve battery levels. MIMO modes can be used when an active application benefits from MIMO rates or when transferring large files.
