Disclosed herein is a technique for dynamically scaling a low-power self-refresh (LPSR) idle interval associated with a solid state drive (SSD) of a user device in order to promote enhanced battery life efficiency within the user device. A determination can be made regarding whether the LPSR idle interval is to be scaled up or scaled down. Specifically, the determination is based on a total elapsed since the user device was first powered on and a total number of LPSR transitions or cycles that have been performed in association with the SSD. In turn, the dynamic scaling of the LPSR idle intervals causes NAND power-cycles to be consumed responsibly over an average system lifetime of the user device, which can result in better power management at the user device.
