Thinkpad x220 running TLP with extended battery covers all day (sometimes 7AM to 9PM) of browsing and CLion & PyCharm. I'm a student so the only time it's not being used heavily is when I'm walking from class to class. As the other comment said I get about 5W draw in powertop. All I've done is install TLP as the other comment says. Something else you can do if you'd like to get a huge boon for battery life is get a slice battery [0]. Get both the extended and slice and you'll be able to probably go 20hr.
