Our previous long-lasting champ, the Moto Z Play, turned in an impressive 13 hour, 46 minute result on our battery test. The ZenFone 3 Zoom blows that time out of the water, lasting 16:46 when continuously surfing over an LTE network. Credit the beefy 5,000 mAh battery and the power-sipping Snapdragon 625 inside the new Asus phone.

Those two phones have company at the head of the long-lasting class. The OnePlus 5, the latest flagship killer from OnePlus, is no slouch either when it comes to endurance. It held out for a little more than 13 hours on our battery test, making it a top choice if you want a phone that lasts all day long.

The iPhone 8 Plus joins our list of smartphones that lasted more than 11 hours on our battery test. The 11:16 result for Apple's new 5.5-inch phone tops Samsung's recent spate of flagship releases, including the Galaxy Note 8 (11:11) and Galaxy S8+ (11:04). Those phones join a wide range of devices, from high-end flagships such as the Huawei Mate 9 to less expensive options like the ZTE Blade Z Max and Moto G5 Plus.

Our top list of enduring handsets features devices that last at least 11 hours on the Tom's Guide 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 three bars of service. Just to put this performance in context, the average smartphone lasts 9:40 on our test before running out of power.
