METHODS FOR DETERMINING BATTERY STATISTICS USING A SYSTEM-WIDE DAEMON

Techniques for determining battery statistics using a system-wide daemon are described herein. According to one embodiment, a power management daemon is configured to collect operating status data of a battery of a data processing system by accessing at least one of firmware and hardware coupled to the battery. The power management daemon is a single system-wide component within the data processing system to provide the operating status data of the battery to multiple clients. The power management daemon is also configured to compute battery statistics based on the collected operating status data of the battery. In response to a query received from one of the clients via an application programming interface (API), the power management daemon is configured to return the battery statistics to the client to enable the client to determine remaining time of the battery until being recharged. Other methods and apparatuses are also described.
