Memory for Ultrabook - Scaling SODIMM RAM Density vs. Battery Life
 

Today's test really answers a lot of questions for me, or at least brings to light something I've observed and not spent a lot of time thinking about.

When I buy a new notebook the first thing is do is slap in the fastest SSD available at the time and fill the system full of RAM. There are usually a couple of days in between getting the notebook from the OEM and then 'making it mine'. Before I really didn't think too much about it, but I could always tell the battery life had dropped off, but I never realized exactly how much until now. These tests tell us that you want to use a few memory sticks in your laptop as possible for optimal battery life. It does make a sizable difference to performance.
