Keeping power consumption at a low level is generally important for battery-powered devices, and particularly so for battery-powered wireless communication devices).
US 2011/0207509 A1 discloses various embodiments for providing enhanced battery power conservation in mobile devices. The device may store user pattern data and/or user preference data. The device may include a power management module coupled to the processor. The power management module may monitor a location of the device, wireless signal strength and date/time. The power management module may also monitor and analyze user operation of the device to identify scenarios in which wireless communications can be suspended to reduce battery consumption.
US 2014/0082384 A1 discloses techniques for power management of a portable device. According to one embodiment, a user agent of an operating system executed within a portable device is configured to monitor daily battery usage of a battery of the portable device, to capture daily battery charging pattern of the battery of the portable device, and to infer user intent of utilizing the portable device at a given point in time based on a battery operating condition at the point in time in view of the daily battery usage and the daily battery charging pattern. Power management logic is configured to perform power management actions based on the user intent.
However, these power management techniques may not be adequate in all situations. For example, one or more of these power management techniques may cause power management that is either too restrictive or too indulgent in various situations.
Therefore, there is a need for alternative power management for wireless communication devices.
