Abstract
A method is performed at an electronic device with a display, one or more processors, volatile memory, and non-volatile memory that stores one or more programs for execution by the one or more processors. The method includes periodically comparing an amount of free volatile memory to a threshold level. The amount of free volatile memory is compared to the threshold level with a first periodicity when the display is off and with a second periodicity that is shorter than the first periodicity when the display is on. The method also includes, in response to a determination that the amount of free volatile memory does not satisfy the threshold level, deallocating volatile memory by terminating one or more processes based on priority levels of the one or more processes.
