Smartphones with seriously long battery life (roundup)

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 six 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.

Huawei Ascend Mate 2 4G (unlocked), June 2014

The Ascend Mate 2 4G is a mouthful of a name, but at least its battery can last all day. Literally. For our video-playback test, this handset took 25 hours and 54 minutes to fully drain, making it our top contender for an everlasting phone. Read the full Huawei Ascend Mate 2 4G review.

Samsung didn't hold anything back when it created its flagship GS5. Packing a blazingly fast quad-core processor, a gorgeous 1080p screen, and a water resistant body, the phone also features a top-notch battery. In our test for video playback, it lasted a solid 15 hours and 18 minutes. Read the full Samsung Galaxy S5 review.

LG G Pro 2 (unlocked), March 2014

As LG's answer to the "phablet" niche of handsets, the G Pro 2 has an expansive 5.9-inch display. That's a double-edged sword: to power that big screen, it needs more; but that extra size means LG can fit in a bigger battery. Enter its removable 3,200mAh cell, which was able to push through 14 hours and 1 minute of video playback. Read the full LG G Pro 2 review.

Nokia Lumia 1320 (unlocked), January 2014

For Windows Phone enthusiasts, the Lumia 1320 will stand out in a number of ways. First, it has a shockingly orange paint job, its 6-inch screen is massive, and most notably, its battery is ample. It soldiered on for a whopping 43 hours and 10 minutes for our talk time test. Now that's some serious juice. Read the full Nokia Lumia 1320 review.

LG G Flex (multiple carriers), January 2014

The G Flex not only has a novel, bowed body that can withstand 88 pounds of pressure, but its 3,500mAh battery inside is curved too. During our drain test for video playback, the handset lasted an impressive 17 hours and 49 minutes -- that's plenty of time to watch your videos on that immersive curved display.

Motorola Droid Maxx (Verizon Wireless), August 2013

The Droid Maxx has a big, colorful screen and plenty of features, but sadly for the rest of the world is only available in the US. Its camera takes great photos too, but the real story is that its battery kept going for 15 hours and 50 minutes in our drain test of continuous video playback. That's almost an hour more than its predecessor, which lasted 14 hours and 53 minutes. Read the full review of the Motorola Droid Maxx.
