That's why I avoid Electron software when possible. I use nheko instead of Element for my Matrix client, avoid VSCode unless I really need it, and shun Discord when possible.

I'm not talking about Electron software, Electron doesn't exist on iOS or Android.

Android and iOS have integrated webview componentes that are much more lightweight and are used in a lot of "native apps". Very often you will never notice if you don't look at the source code.
