hours, days, i did not measure it, normally my battery in normal working
load lasts about 10hrs, suspended a night is no problem, in my holidays
it lastest a week.

i use debian testing with gnome3, and i do not use any special hacking,
or scripting. some time ago i discovered the TLP which is doing a great
job in configuring the kernel correctly.
but i use a very long kernel commandline:
i915.i915_enable_fbc=1 i915.lvds_downclock=1 pcie_aspm=force

i do not use hibernating, simply because i encrypted my home and swap,
and since gnome3, gnome is not supporting hibernation to an encrypted swap.
