I have done an 8-hour work day on battery. I definitely could not do two such days on battery.
If I was compiling the entire time, or on Zoom calls the entire time, it would last for a shorter time, but that is unrealistic for me.
I have done a 2-hour Zoom call, and it seems to eat less than 30% of the battery.
It also has all the corporate “security” software installed, I’ll bet money that it would last longer without that stuff.
