What settings?
Tweak the power profiles. When on battery, set the max CPU to 75% and keep the display at 30% brightness (which is still plenty bright). As for the rest of the settings, switch all the options to max savings when on battery and max power when plugged in.

5+ to around 6 hours of battery life.

Don't know if can do a bios underclock, but you can probably prevent it from going into its higher p-states by adjusting the cpu throttling power options.
