Business Smartphones With the Longest Battery Life

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. The devices on this list have the endurance to last through the end of the workday and beyond.

Note: Numbers represent battery life with continuous Web browsing over Wi-Fi.

Battery life: 14 hours and 45 minutes

This huge phone comes with a sizeable battery life to match. The Huawei Ascend Mate 2 lasted an incredible 14 hours and 45 minutes with continuous use. The Ascend Mate 2's battery is so beefy that Huawei even lets you use the phone as a recharging station for your other mobile devices. Just connect a smartphone, tablet or notebook to the phone via a USB cable so you can refuel a second device on the go. Meanwhile, its enormous, 6.1-inch (15.5 cm) screen is another potential perk for business users — if you can handle the extra bulk. The large display gives you plenty of room to work, but it also makes the phone less portable and harder to use with one hand.

  • 4G LTE capable
  • Expandable memory
  • Long battery life

Battery life: 13 hours and 15 minutes

The OnePlus One is a great 5-inch (12.7 cm) business phone with high-end hardware, great software features, and an eye-popping 13 hours and 15 minutes of battery life. OnePlus doesn't have the name recognition of major manufacturers such as Samsung or Apple, but the company's flagship phone has the specs to match up to the Galaxy S5 and iPhone 5s. The OnePlus One also includes useful security features, such as Privacy Guard, which lets you block individual apps from accessing personal information stored on your device, plus built-in encryption for text messaging. It's not available through major carriers like AT&T or Verizon, but even though you'll pay more up-front for the device than you would for a subsidized smartphone, you won't be locked into a pricey two-year contract.

Battery life: 12 hours and 25 minutes

The new Nexus 6P is one of the few smartphones you can buy that runs on Android 6.0 Marshmallow, the latest version of Google's mobile operating system. And since it's a Google Nexus phone, buyers can expect quicker software updates than you'd get on other devices. You also get an excellent fingerprint scanner, fast performance, a really roomy 5.7-inch display – and, of course, extremely impressive battery life.

  • Long battery life
  • Early software updates
  • Always-listening voice commands
  • Fingerprint scanner
  • Fast performance


Battery life: 11 hours and 30 minutes

Google's Nexus 5X packs all the software advantages of its more premium sibling (the Nexus 6P) into a smaller, more affordable package. The Nexus 5X still provides a roomy 5.2-inch display, as well as long battery life, fast performance and a fingerprint scanner for added security. And, like the 6P, the Nexus 5X runs on Android 6.0 Marshmallow, which offers great new features like a context-aware personal assistant app and always-listening voice commands.

Battery life: 10 hours

Last year's iPhone 6 Plus actually lasts longer on a charge than the newer model, the iPhone 6s Plus. That's because Apple actually slimmed down the battery to make the new phone thinner overall.  Fortunately, the older, longer-lasting iPhone 6 Plus is still available to purchase, and it's still one of the best business phones around. Perks include a huge 5.5-inch display that gives you tons of room to work, a fingerprint scanner for extra security, fast performance and an excellent selection of productivity apps via the App Store.

Battery life: 9 hours and 42 minutes

Thinking of upgrading to Samsung's latest flagship phone, the Galaxy S6? You might want to think again, if you value longevity. In a quest to make a slimmer smartphone, Samsung downsized the battery in the newer version, so it dies far quicker than last year's model, the Galaxy S5. Fortunately, the older version is still available to purchase, and still a top-notch work phone with a sharp 5.1-inch display, a fingerprint scanner and even split-screen multitasking.

  • Long battery life
  • Expandable memory
  • Removable battery
  • Split-screen multitasking
  • Security features

Battery life: 9 hours and 30 minutes

Motorola claims that its new flagship phone can run for two straight days without a charge; however, with regular use, we found its staying power to be a bit below that. Still, the Droid Turbo's 9 hours and 30 minutes of battery life is pretty impressive for a smartphone this powerful. It packs a supersharp, 5.2-inch quad-HD display; a blazing-fast quad-core processor; and a whopping 3GB of RAM. And its huge 3,900-mAh battery is the biggest we've seen in a U.S. smartphone. Plus, the Droid Turbo comes with a bunch of handy software features, like always-listening voice commands and Moto Display, which makes it easier to view and act on incoming messages right from the lock screen. 


Battery life: 9 hours and 14 minutes

The ZTE Grand X Max+ is an amazingly affordable phablet with extremely long battery life. The smartphone sports a huge, 6-inch display that gives you tons of room to work. And since it ran for more than 9 hours on our battery-life test, you can count on this phone to last well through the end of the workday. Best of all, the device costs just $169 with no two-year contract required, making it an enticing option for budget-minded business users.

  • Long battery life
  • Large display
  • Affordable price

Battery life: 9 hours

Samsung's Galaxy S6 Edge may be a bit more expensive than our overall favorite business smartphone — the standard Galaxy S6 — but it justifies the steeper price tag with a sleeker design and some nice extras. One such bonus is about an extra half-hour of battery life, for a total of about 9 hours. The phone's other best features are also found on the non-Edge model, including a reliable fingerprint scanner for added security and a multitasking mode that lets you run two apps in a split-screen view.
