Consumes more battery

Makes my laptop processor work harder (i7 2.8); I looked at system monitor and my cpu fluctuates from 20%-75% when I have no other apps running except Desktop Monitor. I like the useful readouts (measurements were accurate and I compared them with other monitoring apps); but it makes my battery last from 6hrs to 2hrs. I stopped desktop monitor for the meantime; until this issue is fixed. Any further fixes would be definitely be appreciated.
