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.

There’s actually a documentation article on this: https://source.android.com/docs/automotive/power/boot_time
Basically, there’s just much less stuff running on Android Auto.
That, and don’t many of these not actually fully turn off when you shut off the car? They draw 12v standby power and keep their RAM active, just going into a sleep or suspend mode rather than powering off fully so waking up happens pretty much instantly. It’s like the difference between hard powering off your phone vs. just putting the screen to sleep.
That’s how the head unit installed in my car works, anyways.
Won’t this eat up the car battery in long term?
Theoretically yes, if you leave it long enough. But it really isn’t much power draw so probably, like, decades. I think the battery might self-discharge and sulfate by then regardless. And this is nothing new; oldschool radios have a nonzero idle draw as well to keep their clocks running and remeber all your radio stations. I imagine the milliamps required aren’t that much different.
Modern cars have all kinds of standby shit constantly drawing power to check in, keep time, phone home, blink lights, listen for the remote, etc., etc. all the time regardless. The audio system is really only one small piece of that whole puzzle.
That does make sense.
