His Deeds Are Dust

I’ve just charged my notebook’s battery fully, then allowed it to discharge while the machine was idle. First of all, I nobbled the power management settings in Fedora 11 to make sure that the screen stayed bright throughout, and it didn’t perform a neat shutdown when it guessed the battery was close to death.

I have the four cell Li-Ion battery, product ID AA-PB0TC4L, which Samsung claims will last four hours, based on BatteryMark tests.

It took 1 hour 53 minutes to discharge.

I present this figure without further comment because I don’t know whether this type of battery takes a few charge/discharge cycles to gain a longer life, or any other possible explanations.
