Hopefully that's the case. Actually I don't worry about the battery life on Samsung phones. As long as you know how to tinker with the settings, you could get a lot better on the battery juice. It's just that I feel a little bit disappointed because I always thought new proccssor chip = better efficiency = better battery life. Anyway, this test is still a good reference for the future owners especially those who upgraded from S8 series, so that they would know what's coming up for them when they receive the phone.

Better efficiency is true but that doesn't directly translate to longer usage time or longer screen on time.
Example below:
Chip 1 (old architecture design) is running straight at constant 2Ghz = screen on time could translate to around 4hours
Chip 2 (new architecture and more optimized running at constant 2.5Ghz = screen on time could translate to around 4hours
Both devices using the above example mentioned have the same battery life (for SOT) but Chip 2 is more optimized. If Chip 1 need to run at 2.5Ghz to meet Chip2's processing ability, then it might get only 3.5hours of battery life.
Every new gen demands higher processing ability due to more features, more required computation (even for camera to do HDR or white balance or denoise) and better cpu/gpu processing which translate to smoother and faster UI transitions.
The way to increase battery life that you expect here is bumping battery capacity but that will diminish the premium solid looking device that is for 2018's standard here and weight as well.
