Linux should generally have no problem with CPU&al sleep, the problem is often devices around, waking up in weird orders or states, or not waking up at all, or not going to sleep. > The furi_hal_os_sleep() function performs tick suppression inside the OS domain.

Combined with timer coalescing this makes for big energy savings. https://en.m.wikipedia.org/wiki/Tickless_kernel https://en.m.wikipedia.org/wiki/Tickless_kernel https://en.m.wikipedia.org/wiki/Timer_coalescing https://en.m.wikipedia.org/wiki/Timer_coalescing
