Use Teams in Firefox with ublock for battery issues, somehow it consumes much less.

That's because the typed letters appear with a large (often even ~1 s) delay. Close your eyes while typing and you'll be back on you track.

For example, Teams likes to control system-wide audio settings instead of acting like any other application. I had to disable the “allow applications to have dedicated hardware access” feature in my sound card driver to stop it screwing around with my settings. I’ve never had to do this for any other app.

It also likes to “edit” system controls like right-click menus on the task bar. This not only breaks muscle memory, but they also put in a gap so that if you move the mouse onto the menu… it closes.
