We talk about a lot of factors when reviewing laptops, such as processor speed, weight, and wireless capabilities, but invariably, the single most important number readers ask about is battery life. We don't blame consumers for being obsessed with it--after all, who wants their laptop to shut down in the middle of a long flight or at an important meeting?

There is also much opportunity for confusion--different manufacturers measure battery life differently, and for the most part, any battery life numbers they advertise are, to be charitable, generously stated. We've attempted to take the thumb off the scale in our standard video playback battery drain test, which generally shows shorter (but more realistic) battery life than you'd find on a list of specs from a PC maker.

Over the years, we've found the battery life of laptops can range wildly: We've seen some systems push 7 hours, and others have trouble even clearing an hour and a half. Keep in mind that battery run time isn't everything--some laptops achieve long life by tacking on gigantic extended batteries or sticking you with absurdly low-power parts.
For your benefit and ours, we've gone back and cherry-picked the front-runners in battery life for 2010 laptops. Here are our discoveries, broken down across the four categories the majority of people are likely to care most about: Netbooks, 13-inch laptops, midsize laptops in the 14- to 15-inch range, and desktop replacements 16 inches and over.
