Yes, those bright screens use a lot of juice. You can shorten the time out on the screen to help.
Bear in mind, that when you see the battery use 50% of your battery, that actually means 50% of whatever the device used since last change! So if your battery has lost ten percent, the screen has in fact used half of that - 5%! It's a relative measurement.
