When your Mac exits standby, the system is restored to its pre-standby state when that sleepimage file is copied back from the hard drive to RAM. This file is generally the same size as the amount of physical RAM your machine has under the hood. Mac standby and sleep work by dumping everything in active RAM into a file called ‘sleepimage’. Safe sleep ensures that data stored in the main memory of your Mac isn't lost when the computer shuts down due to its battery being completely drained. Standby mode extends how long a laptop can stay in deep sleep on battery power, which could be as long as 30 days. During this deep sleep mode, the state of the user’s session is copied to the SSD and macOS turns off some hardware systems, such as RAM and USB buses. These Macs enter standby after being in sleep mode for three hours, while earlier models enter standby after just an hour of sleep. Standby mode is limited to Macs that start up from an internal flash drive.
macOS will also turn off some of its hardware systems to save power.
Standby saves the user’s current session – open applications, files and windows – on their hard drive. Some computers enter special sleep modes called standby and safe sleep, helping them conserve even more energy. Things change when you leave a Mac idle for a long time.
