I think around 8 hours from 100% to turn off. Bear in mind the battery is 2 years old.

I don't tend to have the screen too bright (live in the UK), Bluetooth disabled etc. Also I spend most of my life in Firefox / SSH / VSCode in that order.

Interesting, thanks. I've apparently got "1:47 (53%)" remaining right now, and that's with a 6-cell slice and 3-cell built-in battery. That's just with Firefox and Citrix open.

I seem to suffer pretty badly from battery anxiety, so 8 hours is a bit of a dream :)
