Smartphones are the Swiss Army Knives of the tech world.
They're cell phones, music and video players, mobile Web browsers, and personal organizers, among other things. Not surprisingly, all this can take a toll on battery life, and when you depend on your smartphone for so much, the last thing you want is for it to run out of juice when you need it most.
Generally speaking, with moderate use, smartphones can give you a full day's performance before needing to be recharged, but not all gadgets are created equal -- some simply run out of steam early, whereas others will hang in there for the long haul.
Below, you'll find six smartphones (in no particular order) with battery usage that really impressed us, whether it was because they scored well in our lab tests for battery drainage, or simply because their usage time stood out from the crowd of humdrum cell phone batteries we encountered (and believe us, we encounter a lot). Give one of these devices a try if you're looking for a phone that packs some decent juice.
