A top-notch business phone won't do you much good if its battery is always drained. That's why smartphones with long battery life make the best work phones.

Editor’s Note: Google recently announced the release of the Pixel 2 and Pixel 2 XL. Both phones are available for pre-order now and will launch officially on November 15. Once we have completed hands-on testing we may revise our recommendations.

Don't be fooled by its name: The Moto Z Play Droid is as good for work as it is for play. For starters, no phone lasts longer on a charge than this one, which endured for an epic 13 hours and 46 minutes on our battery test. You also get a sharp, 5.5-inch display, a fingerprint reader for added security, and a unique expansion port on the phone's back that lets you attach add-ons called "modules." There is also a battery pack that's included so the phone lasts even longer, plus a projector so you can beam presentations onto a wall.

LG's X Power is the longest-lasting budget-priced smartphone you can buy, by far. The device ran for a terrific 12 hours and 58 minutes, which is particularly impressive given the phone's sub-$200 price tag. On the other hand, you won't be impressed by the phone's basic design or modest performance, but the LG X Power still provides good bang for your buck.

Smartphones don't get much bigger than this. Huawei's Mate 9 boasts a whopping 5.9-inch display that's perfect for screen-intensive productivity tasks such as viewing documents and editing spreadsheets on the go. Its battery is big, too, lasting for more than 12 hours, according to our battery test. Fast performance and a security-boosting fingerprint reader on the phone's back round out the package.

The Galaxy S8+ boasts a roomy 6.2-inch screen with fantastic resolution (2960 x 1440), and ironically it also has an excellent battery life of just over 11 hours.
