Also the mobile/cell radio is 2nd biggest power consumption as it must periodically transmit a "hello" handshake to the best received tower/mast it detects, otherwise the cell network would be clogged with data when someone phones or texts a mobile destination. OLED dark mode was promoted to save screen power. It's a myth that dark mode is easier on the eyes at night. Turning down brightness works better. Dark mode saves no power at all on LCD or eink screens. It only saves power on OLED, EL, Plasma and CRT. Only a small difference on the rare VFD graphic panels as they have heated filament cathodes.
It's nearly impossible to turn off the mobile base/cell tower handshake. It still does it when there is no SIM (though in theory not needed then unless it's to do with Emergency Call routing, which still works) and when all data including background is disabled. Only powering off the phone stops it. Sleep doesn't.
