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 a cheaper handset than the Moto Z Droid or Moto Z Force Droid models, 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 S7 Edge

The Galaxy S7 Edge, with its 5.5-inch curved Quad HD Super AMOLED display and its Qualcomm Snapdragon 820 processor, offers a lot of power and a high-res screen. The 3,600 mAh battery inside provides about a day’s worth of battery life during normal conditions, and you might be able to squeeze out a few more if you keep your activities low. In our hardcore testing, with full brightness on, the battery life lasted about 6 hours and 40 minutes. The battery life is about the same if you get the US-based version with the Snapdragon 820 processor, or with Samsung’s own Exynos chips.


  • 5.5-inch Super AMOLED display with 2560 x 1440 resolution, 534 ppi
  • Quad-core Qualcomm Snapdragon 820 processor
  • 4 GB of RAM
  • 32 GB of on-board storage, microSD expansion up to 256 GB
  • 12 MP rear camera, 5 MP front camera
  • Non-removable 3,600 mAh battery
  • Android 7.0 Nougat
  • 150.9 x 72.6 x 7.7 mm, 157 g

OnePlus 3T

The OnePlus 3T launched late in 2016 and quickly became a favorite of ours, thanks to its more powerful Qualcomm Snapdragon 821 processor, 6 GB of RAM and 16 MP rear- and front-facing cameras. The 3,400 mAh battery inside the phone, which is a bit more than the 3,000 mAh battery that was put in the now discontinued OnePlus 3 model, should be enough to get you through a full day of use on a single charge. Overall, the OnePlus 3T should keep you going long enough so you can charge the battery up again at the end of the day.


  • 5.5-inch Optic AMOLED display with 1920 x 1080 resolution, 401 ppi
  • 2.35 GHz Qualcomm Snapdragon 821
  • 6 GB of RAM
  • 64/128 GB of on-board storage, no microSD card expansion
  • 16 MP rear camera, 16 MP front camera
  • Non-removable 3,400 mAh battery
  • Android 7.1 Nougat
  • 152.7 x 74.7 x 7.35 mm, 158 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. 


  • 5.5-inch AMOLED display with 2560 x 1440 resolution, 534 ppi
  • 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
  • Non-removable 3,450 mAh battery
  • Android 7.1 Nougat
  • 154.7 x 75.7 x 8.6 mm, 168 g
