Well on the Qualcomm MSM72xx SoCs, yeah they're pretty similar -- we can reasonably enter power collapse (full shutdown of the ARM11 and peripherals) from idle. But this is not (to my knowledge) true of *all* SoCs out there. Also, resuming from this state can take 5-30ms (depending on how distracted the baseband processor is by what's going on on the network).
