Some people might think that the most important feature in a smartphone is its display size. Others believe it comes down to a phone’s processor performance, or the amount of RAM, or how much storage space it has. Let’s not forget about that battery though. For those that need long-lasting performance, battery life is one of the most important considerations before buying.

Battery technology has gotten much better in the past few years, as smartphones are not only charging faster but lasting longer on one charge. Indeed, your phone can have all of the greatest features and hardware in the world, but they become useless if the battery doesn’t last very long. However, there are plenty of high-end smartphones you can purchase that have solid battery life.

Let’s take a look at our picks for the Android smartphones that we believe offer the best battery life.

Editor’s note: We will be updating this list regularly as new devices launch.

Huawei Mate 9

With its big 5.9-inch Full HD display, its powerful Kirin 960 processor, dual-SIM capabilities, and an impressive camera setup, the Huawei Mate 9 may be one of the best big phones you can buy. The 4,000 mAh battery inside the Mate 9 is also one of the largest found on an Android flagship smartphone. In our own tests, we discovered that even with heavy use, the Mate 9 will last about six hours or so on a single charge. Again that’s for heavy gaming-oriented users. Most people will likely be able to use the Mate 9 for more than a day on one charge, and perhaps even through two whole days or even longer.

BlackBerry KEYone

The BlackBerry KEYone might just be the most unique Android handset on the market right now. With its 4.5-inch 1080p display (with a 2:3 aspect ratio), physical keyboard, and industrial, beefy design, it’s certainly an eye-catching device. One of our favorite things about the phone, though, is its amazing battery life. In our testing, we were able to achieve at least four hours of screen-on time, sometimes reaching up to six or six and a half hours of screen-on time in one day. That’s all thanks to the power-saving Snapdragon 625 processor under the hood, as well as the non-removeable 3,505 mAh battery.


  • 4.5-inch IPS LCD display with 1620 x 1080 resolution, 434 ppi
  • 2.0 GHz octa-core Qualcomm Snapdragon 625 processor
  • 3 GB of RAM
  • 32 GB of on-board storage, microSD expansion up to 2 TB
  • 12 MP rear camera, 8 MP front camera
  • Non-removable 3,505 mAh battery
  • Android 7.1.1 Nougat
  • 149.3 x 72.5 x 9.4 mm, 180 g

Moto Z Play

The Moto Z Play may be an older mid-range phone now (released in 2016), but it still supports the growing number of first and third-party Moto Mods that extend its functions. It also packs in a 3,510 mAh battery that lasted an astonishing 16 hours and 13 minutes with our Wi-Fi browsing test. Oh, and if that’s not enough battery life for your for some reason, you can snap a Moto Mod battery directly on its back to extend your browsing time even more. If you’re looking for a prepaid Verizon phone that’s unique and won’t skimp out on battery life, you should get the Moto Z Play.


  • 5.5-inch Super AMOLED display with 1920 x 1080 resolution, 403 ppi
  • Qualcomm Snapdragon 625 processor
  • 3 GB of RAM
  • 32 GB of on-board storage, microSD expansion up to 256 GB
  • 16 MP rear camera, 5 MP front camera
  • Non-removable 3,510 mAh battery
  • Android 7.0 Nougat
  • 156.4 x 76.4 x 7 mm, 165 g

Samsung Galaxy S8 Plus

Not only is the Samsung Galaxy S8 Plus a powerful phone, it’s one with solid battery life too. Offering a 3,500 mAh battery that’s bigger than even the Note 8, you can easily get a full day’s usage out of the S8 Plus, if not a good day and a half.

Moving to the rest of the specs, Samsung included a curved screen on both the S8 and S8 Plus this time around, as well as a unique 18.5:9 aspect ratio that allows for a much more comfortable in-hand feel. The company even ditched its famous physical home button and included on-screen navigation keys (finally). Under the hood, the Galaxy S8 Plus comes with the Qualcomm Snapdragon 835 processor (or Exynos 8895, depending on the region), 4 GB of RAM, 64 GB of on-board storage, and one of the latest versions of Android, 7.0 Nougat.

Samsung even launched a few extra accessories alongside the S8 Plus that you should definitely consider checking out. The new Samsung DeX dock lets you use your S8 Plus as a desktop computer, and there’s also a new Gear 360 camera that allows for shooting video in 4K and live streaming to YouTube. Of course, there’s also a new Galaxy S8-compatible Gear VR headset, complete with a controller for easier navigation.

All in all, the Galaxy S8 Plus is one of the most promising smartphones launching in 2017.

OnePlus 5

The OnePlus 5 is the latest flagship smartphone from OnePlus, sporting top-of-the-line specifications, smooth and snappy performance, a wonderful software experience, and pretty solid battery life at just a little over a full day’s use.

This phone is really great. It sports a Qualcomm Snapdragon 835 processor, up to 8 GB of RAM, dual 16 and 20 MP cameras, and it’s running a much more refined version of OxygenOS atop Android 7.1.1 Nougat.

Even though the device is missing a couple notable features like ingress protection and microSD card expansion, we still think the OnePlus 5 is worth the $479 asking price. Be sure to check out our full review for more details!


  • 5.5-inch Optic AMOLED display with 1920 x 1080 resolution, 401 ppi
  • Qualcomm Snapdragon 835 mobile platform
  • 6/8 GB of RAM
  • 64/128 GB of on-board storage, no microSD expansion
  • Dual 16 and 20 MP rear cameras, 16 MP front camera
  • Non-removable 3,300 mAh battery
  • Android 7.1.1 Nougat
  • 154.2 x 74.1 x 7.25 mm, 153 g

Google Pixel XL

The Google Pixel XL has arrived, and Google’s flagship Android Nougat smartphone is an impressive handset, thanks to its Qualcomm Snapdragon 821 processor, 4 GB of RAM and some of the best smartphone cameras in existence. The 3,450 mAh battery inside the new flagship lasted about 4 hours and 45 minutes when we put it through our high-end gaming benchmark. Most of the time, you should get about a day’s worth of battery life with normal use with the Pixel XL, and that’s not bad at all considering all the hardware inside.

  • Qualcomm Snapdragon 821 processor
  • 4 GB of RAM
  • 32/128 GB of on-board storage, no microSD expansion
  • 12.3 MP rear camera, 8 MP front camera
