Various embodiments of systems and methods are disclosed for reducing volatile memory standby power in a portable computing device. One such method involves receiving a request for a volatile memory device to enter a standby power mode. One or more compression parameters are determined for compressing content stored in a plurality of banks of the volatile memory device. The stored content is compressed based on the one or more compression parameters to free-up at least one of the plurality of banks. The method disables self-refresh of at least a portion of one or more of the plurality of banks freed-up by the compression during the standby power mode.
