Similar to https://orionfeedback.org/d/10528-orion-rc-using-significant-energy/3 but with Version 0.99.134-beta (WebKit 622.1.9.19.2) --> filing this as a separate issue.
Tools --> Low power mode is On
Steps: Watch a Youtube video on Orion. Battery indicator shows Orion using Significant Energy. This is surprising for Orion. I have seen this on Firefox where it has been a longterm problem but Orion has usually been pretty good at barely consuming resources while playing YT videos.
Enclosing information requested by @dino in the prior issue: " can you please share a list of active web-extensions? and if possible a screenshot of CPU uses by all Orion + child processes to debug the root cause."
Happy to try to get more data if I can.
Active Extensions:

Orion/child processes CPU: (As much as fit on screen)

Battery status/Energy use:

Orion is usually very low power consumption. Surprised to see it reporting high energy use.
