iStat Menus has a thing where you can put the current power draw in watts in the menu bar, and it's easy to run at 4-5W with an M1 Pro while just surfing and text editing. With just a couple spikes for compiling, installing, etc. you can very easily hit close to 20 hours for many coding workflows if that's your goal.
I like a bright screen, so I usually get closer to 10 hours, but it charges fast — about 50% in 30 minutes if it's low. (The last 20-30% runs a little slower because battery chemistry.)
