Smartphones are the Swiss Army Knives of the tech world.
They're cell phones, music and video players, portable games consoles, mobile Web browsers, and personal organizers; the list goes on and on. Not surprisingly, all this can take a toll on battery life (especially on handsets with hefty, bright screens) and when you depend on your handset for so much, the last thing you want is for it to run out of juice when you need it most.
With moderate use, smartphones usually can last a full day before needing to be recharged, but not all gadgets are created equal -- some simply run out of steam early, while others can hang in there for the long haul. Below, you'll find eight impressive devices that scored high in our CNET Labs battery tests for continuous video or talk time. Give one of these devices a try if you're looking for a handset that packs some serious juice.
Motorola Droid Turbo, November 2014
Motorola's family of Droid devices are known for their high capacity battery, and the Turbo is no exception. The handset packs a 3,900mAh battery that not only has quick-charge technology, but its video playback can also last up to 14 hours and 43 minutes. And feel free to talk your ear off too -- the phone went 34 hours straight for continuous talk time. Read the full review.

In our test for video playback, it lasted a solid 15 hours and 18 minutes. Read the full review.

LG G Vista, September 2014
With its 720p display and Snapdragon 400 processor, the G Vista doesn't have the most powerful hardware internals around. But for a competitively priced phablet, its battery life is ace. Between two US carrier models, the phone played continuous video anywhere between 14 to 17 hours straight. Read the full review.
BlackBerry Passport, September 2014
Despite
its unusual square design, the Passport is a powerful handset that'll
keep you productive with its comfortable touch-sensitive physical
keyboard. And with its impressive battery life, you can afford to keep
working -- it was able to last over 26 hours during our lab test for
talk time.
