I assume, part of the changes Android has, would be more ways to reduce standby battery drain, tuned to mobile phones?
And maybe their alternative for systemd is more suitable for mobile phones.

And since I irrationally favour Linux, perhaps we can come up with a systemd-mobile, tuned for RISK and ARM based mobile-phone systems, which keeps in mind, power used by cell-radio, WiFi modules, etc.
But of course, first and foremost, we need to have a standardised pre-boot system, like we have for PCs, making it much easier to manage development, without piling up plastic and Silicon paperweights.
