It is, which is why I avoid it. The amount of power VSCode consumes vs others is significant. Jetbrains products even have a low power mode which turns off indexing. Can run that thing all day long without plugging in.
I also use Ripcord for slack instead of that electron client.
I always avoid electron apps so I don't have to have a separate flow when I am on battery vs plugged in.
Multiple Chromium browsers that probably send telemetry to Google, no less.
I'd be slightly less hateful of Electron if it used a non-Google engine, but alas Chrome is the new 90's Internet Explorer and everyone needs to bend over backwards to it.
