Systems and methods for determining a battery-level of an electronic device and conserving the battery charge of the electronic device are disclosed. The battery consumption of an electronic device may be reduced when the user or the device learns via user input or determines via prediction that the battery will be depleted before the next possible charge cycle. Reducing battery consumption could be accomplished by accessing an application requiring less power consumption and/or delaying post-processing of sensor data related to that application, for example a camera application. Prediction of battery life could include determining the time to the next expected battery charge and delaying the processing of sensor data until the electronic device is plugged in and charging or has reached a predetermined charge level.
