When I'm on the go and want my Lenovo P50 mobile workstation laptop to last an entire cross-country flight so I can get work done (a real use case), I have to use Slack web client, Sublime instead of VS Code, Firefox instead of Chrome, and manually close out of a whole bunch of less important Electron apps (Discord, Gitter, Skype, Upwork, Spotify, Atom, etc.), and only then will powertop show an acceptable < 20W of power draw instead of close to 30 W with all of the Electron apps open, allowing my laptop to have five hours of battery life instead of two, which means it will last the whole flight.
I still have a bunch of native Linux desktop apps that I prefer to use to this very day that are fast, responsive, and don't make my laptop's fans sound like a leaf blower while failing to prevent the heated chassis from scorching my lap.
Devs don't let other devs use Electron -- as a real alternative, consider using the wxWidgets cross-platform native GUI app framework (with its myriad language bindings) so that you can have a single code base that supports all of the major platforms.
