Users of mobile devices often experience a scenario where the available battery power is low, while a user activity is ongoing. Currently, users take actions such as reducing display brightness, turning off connectivity options, etc. to conserve battery power. However, such actions may not ensure that enough battery power is available to complete the user activity. This disclosure describes techniques to selectively enable smartphone power-saving features to achieve a user activity goal, or a desired amount of operating time to remain. The techniques can be enabled by a user of the device, or with user permission, can be enabled automatically. A power consumption model that provides a prediction of device power consumption is utilized to selectively enable power-saving features to meet the specified goal.
