Why are Android boot times relatively slow? (lemmy.ml)

The storage and processing power of modern smartphones are touted to rival those of a typical laptop. Yet, my trash-picked testing system from over a decade ago with a bottom-of-the-barrel SATA SSD can still boot to the Linux desktop faster than all but one of my Android devices.

Understandably, this isn't a huge priority since very few people are cold booting their phones every morning. But is it just plain unoptimized? How hard would it be to optimize? Do security features and checks bog it down? Is it that there's many tiny files to load when booting? What gives?

I don't know.

But it's not all phones. I've had some android devices that take over a minute to start up, but my current Xperia 1V also only takes 20 seconds to ask for the pin, then another 2-4 seconds for the home screen to fully show.

I do want to point out that phones aren't running blazing-fast ssds. Lots of android devices run fairly sluggish eMMC flash.

For a while now, I've been making sure the android devices I buy are running a recent standard of UFS flash, instead. The difference is noticable, just with stuff like opening apps and moving files around.
