Set it to percent.

The battery time indicator is fluctuating as it is dependent on current CPU usage.

This is very true. Also because of the fluctuating processes, this makes the battery gauge a tad inaccurate ;) I'd suggest using the battery percentage as more of a guide as to when you need to plug up.

Be more consistent in the power demands of your usage.
