I do sometimes turn off location, Bluetooth, WiFi and cell data and keep the backlight at the lower end of it's useful range. But beyond that, are any of these refinements needed or useful? It's not as if we're on an extended wilderness journey with only a solar charger available for power needs.
The built-in power management of current generation phones is remarkably good compared to just a few years ago. I pay attention to battery consumption because I'm geeky enough that it amuses me to do so. But I don't think I'd try to talk the average person into extreme battery conservation measures. Just use the device and enjoy what it can do.

Unless I absolutely need them, I keep location and Bluetooth turned off on my tablets and phones. I keep the light turned down because it blinds me any brighter.
