5 Work Smartphones with the Longest Battery Life (2017)

5 Work Smartphones with the Longest Battery Life (2017)

The names on this list might not be as familiar as Apple or Samsung, but they dominate the market when it comes to long battery life. If your workday is more like a marathon than a sprint, and long battery life is essential, one of these phones might just suit your needs.

The battery life listed here is not the number claimed in press releases, but what we measured with continuous web browsing over Wi-Fi during the testing and review process.

This phone does two things well: It lasts an insanely long time (longer than 16 hours), and it has very good dual rear camera lenses (with 2.3 x optical zoom capacity built-in). For a reasonable $329, this Asus device also comes with high-end features, such as a fingerprint sensor unlock, sturdy Gorilla Glass 5, an AMOLED display and a USB Type-C port.

What this long-lasting phone doesn't deliver is a great interface, or the most recent OS. While higher-end Android phones, such as the Samsung Galaxy S8, are running Android 8 Oreo, Asus has kept the Asus ZenFone 3 Zoom running the now somewhat outdated Android 6 Marshmallow. There are also carrier limitations with this device; it doesn't work with Sprint or Verizon, which could be a major roadblock to adoption for business users in certain regions.

The overall performance of this phone won't blow you away. At times it feels lower end, but it is about half the price of many higher-end smartphones, and it won't die when you're working a double.

If you want a smartphone with above-average dual cameras, passable performance (thanks to the Qualcomm Snapdragon 430 processor) and an ultra-long battery life (15:19) all for just less than $200, this is it.

The Asus ZenFone 4 Max's $199 starting price point makes it an accessible choice for a small-to-medium business that needs to outfit field employees with smartphones that are functional but not super flashy. Another benefit to choosing this device is the dual SIM card capacity, which makes it easy for multiple users to share the same device and/or for one user to use one device for business and personal use (with two phone numbers). 

While this phone is quick enough to keep up with basic app use, it's not ideal for playing games or intensive multitasking. Just remember, this phone is about stripped-down efficiency and a super long battery life, not luxury features. Like other Asus phones, this model is not compatible with Sprint or Verizon services.

The Moto E4 Plus is a reliable, wildly inexpensive ($159.99) smartphone with a battery life (14:48) that can go the distance. The fingerprint sensor and single rear camera lens are both fine, if unremarkable, but one thing this long-lasting Motorola brings to the table is accessibility and availability. Unlike number one and two on our long battery life list, this phone can be used on nearly any major carrier, including Sprint and Verizon.

The interface on the Moto E4 Plus looks pretty much like every Motorola phone interface you've ever seen, which isn't necessarily a bad thing, since it's also intuitive to navigate. A nice touch the Moto E4 Plus has is a sleek metal back panel, which lends the phone a higher quality feel than some plastic competitors.  

The performance of the Moto E4 Plus is speedy enough for business use, and the insanely long battery life allows for plenty of connectivity, even if you're away from a power source for long stretches of time.

This Motorola device might seem pricey compared to other winners on our list, but at 5.5 inches, the Moto Z Play offers a significantly larger screen than most of the competition. Plus, it still manages a long battery life of 13 hours and 46 minutes.

The respectable Snapdragon 625 processor can easily handle business multitasking (but not high-octane gaming), and the roomy screen is a real productivity tool for workers on the go. The physical build of the phone feels decently high quality, and the inclusion of a headphone jack is a nice touch, especially for people who don't want to deal with wireless headphones.

On the flip side, the camera on the Moto Z Play isn't great, plus it's pricier than other long-lasting phones. That said, if you want a business device that's larger than a phone but isn't quite a tablet, and you require a super long battery life, the Moto Z Play is worth considering.

The worst thing about the OnePlus 5 smartphone is that it isn't supported on Verizon and Sprint, but if you don't rely on those carriers, you should seriously consider buying it for its battery endurance, among other things.

From the excellent dual cameras and sleek aluminum design to the clever inclusion of buttons that allow you to navigate "back" and access recent apps, this device is by far the best all-around machine on the longest-battery-life list.

While the other phones on this list have mediocre processors at best, the OnePlus 5 has the same processor (Snapdragon 835) as the significantly more expensive Galaxy S8, which makes even high-level multitasking and gaming within reach. The speakers on the OnePlus 5 won't blow you away, but the display is excellent for day-to-day business use, and when you remind yourself that all this functionality costs just $479 and lasts on a single charge for longer than 13 hours, the argument for adopting this oddball smartphone becomes a lot more convincing.
