My car’s android unit has some quad core processor , and it instantly boots up and reaches the home screen where as my phone takes almost 30 seconds or a minute to reach the home screen despite having much better hardware.

    Among the other things that have been said, Android auto often makes use of some tricks too. Things like hibernation that phones typically do not do (Probably the biggest one right here), Animations to hide loading time, loading some critical, but not latency sensitive services until after the boot. and some other misc service management stuff.

      Phones do actually have a “deep sleep” mode, where they suspend apps, downclock the CPU, and turn off features like radios.

        Yep but that’s not hibernate, that’s what happens when you leave your phone on bed side table for a couple hours when you sleep. You can get very low power under these, which may be comparable to your cars alarm system.

        Android emulators though have the ability to suspend all activities to disk and come back in a few seconds.
