These devices lasted at least 9 hours on the Laptop Mag Battery Test, which involves continuous web surfing over 4G LTE. We set each phone’s display to 150 nits to normalize for brightness and make sure each handset is receiving at least 3 bars of service. See for yourself which smartphones keep going and going.
A $299 unlocked Android phone that blows away the competition in terms of battery life, the Huawei Ascend Mate 2 truly makes the most of its huge 3,900 mAh battery. This 6.1-inch phablet lasted a very, very long 14 hours and 43 minutes on the Laptop Mag Battery Test. In fact, the Ascend Mate 2 can charge other gadgets (with an optional cable). The 720p screen is quite bright, and the mid-range Snapdragon 400 processor provides good performance for the price.
If you haven't heard of the OnePlus One, you should put it on your smartphone shortlist. Available for just $299 unlocked, this device lasted a fantastic 13 hours and 16 minutes on our battery test. There are plenty of other reasons to scoop up the One, including the very flexible Cyanogen Mod software that runs on top of Android and generous 5.5-inch, full HD display. We also like the gritty texture on the back, so you're less likely to drop this long-distance runner.

The Xperia Z3 is a fantastic choice for T-Mobile subscribers. It boasts a sharp 20.7-MP camera and a dedicated shutter button that lets you snap pictures even while submerged. We also like the bright display and loud front-facing speakers.

Nokia's first phablet is a doozy, offering a glorious 6-inch 1080p display, a zippy Snapdragon 800 processor and an excellent 20-MP camera. Not bad at all for just $99. It gets better. The Lumia 1520 lasted an imprssive 11 hours and 28 minutes on the LAPTOP Battery Test. If you're thinking about Windows Phone and want a big screen, this is one heck of a bargain.
The Galaxy S5 improves on its predecessor in multiple ways, including a water-resistant design, fingerprint reader and even a heart rate monitor. But this powerhouse can also get you through the day. The T-Mobile version of the S5 lasted a whopping 10 hours and 57 minutes on our battery test. The AT&T (9:28) and Sprint (8:34) models also delivered great endurance. The Verizon S5 lasted 7:30, which is still above average.
The HTC One M8's gorgeous metal design, powerful performance and booming speakers make it one of the best Android phones yet. Another big reason this device earned a 4.5-star rating from us? Its 2,600 mAh battery lasted 9 hours and 52 minutes on our battery test over Verizon's network. We saw an even longer 10:50 on T-Mobile and a still-excellent 9:26 on Sprint. The AT&T version lasted 8:42.

The "Plus" in iPhone 6 Plus goes way beyond mere size.

The Galaxy S5 Active is a long-lasting smartphone in more ways than one. The device is rated to withstand multiple drops from 4 feet, and it can be submerged in up to 3 feet of water for 30 minutes. It's also dust-proof and can easily survive sever temperatures. This AT&T exclusive phone can also go the distance when it comes to battery life, as the handset lasted an excellent 9 hours and 37 minutes on our web surfing test.
With a 3,900 mAh pack, the Droid Turbo has one of the largest batteries every inside a smartphone. And it definitely pays off.
