@Ugle the key point here is understanding what’s actually running and whether your expectations match how Chromium-based browsers are designed.
Chromium browsers, including Brave, run every tab and extension as a separate process. Each tab is its own process, and the same goes for every extension and many internal browser tasks. This design improves stability and security, but it can lead to higher memory and CPU usage on the surface.
There’s a common principle in computing that unused RAM is wasted RAM. Chromium-based browsers intentionally make use of available memory to ensure fast and reliable performance. That includes keeping processes active so that switching tabs or actions feels instant. However, the browser does put inactive tabs to sleep and adjusts usage dynamically. It tries to balance performance without overloading your system.

Maybe there’s a way to make all extension on limited access?

Yes, there is. Go to brave://extensions and click Details on the extension you want to limit. This opens a page where you’ll see:
Allow this extension to read and change all your data on websites you visit:
You’ll have three options:
- On Click
- On All Sites
- On Specific Sites
If you change it to On Click or choose specific sites, it can reduce the extension’s impact on memory, CPU, and battery.
Also, it’s worth recognizing that many users report battery issues on MacBooks in general. One random example would be https://discussions.apple.com/thread/255511501
