Teams specifically is horrendously badly engineered on top of being an Electron app. Technically speaking it's like the polar opposite of VS Code despite being made by the same company.
However, Chrome is the most popular browser by far. Does that mean that all the people bragging about their MBP's 10+ hour battery lifes aren't doing what probably the majority of users are (browse the web in a Chromium-based browser), and thus their anecdata isn't a representative sample?
That said, it’s not that uncommon for Mac users conscious about battery life to be using Safari where they can instead of Chrome, keeping Chrome instances down to a minimum. From what I’ve seen in discussions across the web, battery friendliness is one of the most cited if not the most cited reason why people use Safari.
I wish Google would pause feature development for a while and focus on efficiency, because that’s easily where Chrome is weakest, but that’s never going to happen so long as it’s the dominant browser. It makes Google more money to instead develop whatever they think will push more people towards Google services.
The only time I have battery issues is if I am working in a tree and a linter gets over aggressive or something like that where the constant load makes the CPU fan spin.
Normally I go an entire day on battery and just don't think about it. Fairly bright screen, Amphetamine running to prevent sleep and display from turning off.
