Google Meet lasts about 1h 20min on my 2021 M1 MacBook Pro, so it seems about right

If this is using Chrome it’s likely because Meet uses non-hardware accelerated codecs there. Under Safari it’ll use accelerated h.264 and be much easier on battery.

This comment caught my eye - because I'm using Chrome too.

Is there a way to enable hardware accelerated codecs in Chrome + Meet?

(I have no idea what that means, I'm just quoting you)

I checked my Chrome settings and "Use hardware acceleration when available" is enabled for what that's worth.

Not sure. There’s extensions that force YouTube to serve h.264 so it seems like something similar should be possible with Meet.

Doesn't seem right. I used Google Meet for a few hours the other day and it was still at 93%. This is a MacBook Pro M2

Not sure why you were downvoted, as this is Ask HN, and you replied with a fact. Power management is my GOTO retort when I meet a Linux fanboy:

"Linux runs the US nuclear submarine fleet!"

"Of course it can run there, they have unlimited power available."

So does the power point that 95% of laptops are plugged into and they don't charge $200 for 8gb of memory either.
