No.

Battery drain is quite different between backlite LCD and eInk displays. The former draw the same amount of power all the time that they are on. eInk display only use power when redrawing the screen; they use no power while you are reading a particular page.

If you change screens fast enough so that you reach the "6000 screen" limit in, say, 4 hours you'll drain an eInk Kindle but only 1/2 drain a Fire.
