Your crazy. :)
Battery life depends on a number of things. How old is the battery? Do
you regularly use it until it is discharged or do you keep it in a
docking station or on AC power all the time? Does your laptop utilize
speedstep to adjust CPU speed, fan speed, etc.? Do drive the CPU at
100% all the time using setiathome or something similar? Do you have
apm or acpi enabled?
All of these things will vary how long a battery will last. I routinely
run my laptop on battery alone until it down to 15 or 12 % before
plugging in the AC power. This keeps the battery from getting a memory
and degrading. I originally kept the laptop in a docking station almost
all the time. That battery quickly was reduced to a run time of less
than 30 minutes. The new battery I routinely get 2.5 to 3 hours of run
time and have for close to a year now.
