we have an excellent operating system to crib hints from in Maemo, a fully Debian based pre-systemd gnu-linux OS, we can also learn from Jolla/Sailfish which is a linux phone company and OS started by foremer Nokia/Maemo team members as well as Maemo community members..

Some of these are common sense though the Maemo team worked hard on dynamic scaling, verifying power usage of system programs, and generally keeping power waste to a minimum, to the point where dimming the screen and limiting Bluetooth, Wifi, nd modem made a big difference on battery life for a N900 user.
