Why has WindowServer started to consume battery life?

When you disconnect a power source and just surf a web page, I usually get 10 hours on the battery and my CPU temperature remains below 100F.

But lately, I noticed that WindowServer uses about 10 devices in "Energy Impact", my battery life is less than 7 hours, and my CPU temperature stays around 106F.

What's on?

] macOS 10.14.1 (not beta)
2017 Pro MacBook 15 "2.9 GHz
16 GB RAM

Currently, only Finder, iTunes, Safari and Activity Monitor. Does not help much to close Activity Monitor.

Your Mighty

Quick Update:

Battery life is much better today. Not sure why it was a whole day thing yesterday since I do not really use any different applications or go to any web site other than usual. (If anybody wonder, no dGPU did not cause it since it was 0.0 Volt except when I came home to connect it to AC and a 4K display.)

92% charge by 10 hours left.

Here's a good explanation of what WindowServer is and what can make it eat so much CPU and power. In short, it's the process that makes the displayed windows on your screen, doing what they do – discover, update, etc. With highly dynamic windows, the process will eat more CPU cycles and thus more power.

I thought I had written my first post as I had already started on my computer and the problem with WindowServer was still happening even after restart. I thought I remembered writing in the details of my post so I do not understand why it's not in the post. The important part explains why I thought the problem was so unusual and asked me to ask.
At this time, however, it seems to be irrelevant.
