I am using M5 MacbookPro and facing a similar issue. The CPU usage for Code Helper stays high after I use Codex VS Code plugin. Before I use or after restarting VS Code without using Codex then the CPU usage kept low.
Same here on my macbook air M4
same
same for macbook pro m2
same here, macbook air M3. VS Code extension version 26.325.31654

I found a fix for this. So far working great. Before this I had to buy a $200 powerbank just to get any useful live span out of a mobile session.

This actually helped, but need to be re-applied with every codex update.
Thanks for this.

I'm issuing the same problem. I'd like to run the patch somebody sent, but I think I prefer to wait OpenAI to solve this. (Hope asap)
Macbook M2, same problem.
