Those specific conditions do not qualify as normal use, but they do indicate that it's not simply the 4.7" display that is causing the significant batter drain.

This could translate into faster loading of applications, webpages and applications that takes significantly less time to process. In the end you may not need as much screen time on the one x compared to the xl.
It is pretty straight forward. You're not going to spend an additional two hours loading apps and webpages on the One XL. Both are blazing fast, and the difference would add up to less than a minute at most over the course of an entire day. At most. The difference in time spent waiting over even a first gen Galaxy device would be minute.
But the real issue here is the S4 has a significantly higher IPC than the Tegra 3 and is much faster in single threaded applications. The Antutu benchmark shows the performance of the Tegra 3 in highly parallel processing loads, a very uncommon use scenario, and not at all similar to loading a webpage or app. I can think of very few tasks outside a highly complex game (which would have been designed to run on the lower end hardware that is much more common) that would actually take advantage of 4 cores on a phone.
At the end of the day, screen on time is a very useful metric for comparing battery life. It's hard to say if the One XL will have significantly better battery sign as few people have posted results so far, but some of the early indications are very promising.
