Linux has drivers for devices shutdown when not used and idle power
states, pretty much like Windows has. Android, who is Linux derived,
took this concept to a much higher level.
Think of a wireless card and you can see on man ath(4): " The driver
does not fully enable power-save operation of the chip; consequently
power use is suboptimal." This is one of the simplest example.

Next, your CPU has performance cores and efficient cores. The thread
per CPU allocation on Linux is on work but it is more advanced.
