Actual usage is what I'm looking for, what good is saying phone lasts for 18+ hours and your actual usages is perhaps 60 mins+/- as you described?
I guess that you'll just have to ignore everybody's battery life posts then, rather than complain about them. When I see somebody say that they found a way to increase battery life from, say, 20 hours to 24 hours by tweaking with SetCPU, or installing a different ROM, or setting Autokiller settings, or changing how often Seesmic checks for notifications, I can put into my own experience how that it may affect my phone, so I find those posts sometimes useful.
