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 one of the best phone battery life performers, it 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 10 Pro

Battery life

The Huawei Mate 10 Pro has all the features one would expect from the latest high-end flagship smartphones on the market. It has a 6-inch OLED display with an 18:9 ratio, a Full HD+ resolution of 2,160 x 1,080, and very small of bezels on the top and bottom of the display. Inside, there’s Huawei’s in-house octa-core Kirin 970 processor, along with a dedicated Neural Processing Unit for faster on-board AI processing. Huawei claims we will see more improvements in AI on the Mate 10 Pro in future updates.

You can purchase this phone with either 4 GB RAM and 64 GB of storage, or upgrade to 6 GB of RAM and 128 GB of on board storage. There’s no microSD card for adding additional storage, by the way, nor does it have a 3.5 mm headphone jack (the slightly smaller Mate 10 has both). The Mate 10 Pro ships with Android 8.0 Oreo out of the box.

The Mate 10 Pro also comes with an IP67 dust- and water-resistance rating, as well as a large 4,000 mAh battery which supports Huawei Supercharge. This allows the Mate 10 Pro to go up to nearly a full charge in about an hour. The Mate 10 Pro also has a fantastic dual-camera setup with a 20 MP monochrome sensor combined with a 12 MP RGB sensor. The phone got a high 97 score for its rear camera features from the image testing DxOMark, which is right up there with the iPhone 8 Plus and Galaxy Note 8.

Specs

  • 6.0-inch Huawei FullView OLED Display with 2,160 x 1,080 resolution, 402 ppi
  • Octa-core Hisilicon Kirin 970 processor

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.

Specs

  • 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, making it one of the phone battery life performers. 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.

Specs

  • 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

Samsung Galaxy S8 Plus

Not only is the Samsung Galaxy S8 Plus one of the best phones, it’s also one of the best phone battery life performers. 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.

Specs

  • 5.8-inch Super AMOLED Infinity Display with 2960 x 1440 resolution, 570 ppi
  • Octa-core Qualcomm Snapdragon 835 or Octa-core Samsung Exynos 8895 processor (depending on region)
  • 4 GB of RAM
  • 64 GB of on-board storage, microSD expansion up to 256 GB
  • 12 MP rear camera, 8 MP front camera
  • Non-removable 3,500 mAh battery
  • Android 7.0 Nougat
  • 148.9 x 68.1 x 8 mm, 155 g

OnePlus 5T

The OnePlus 5 was a solid smartphone, but it wasn’t really up to 2017’s standards on the design front. That’s why OnePlus changed things up quite a bit with the OnePlus 5T.

The first thing you’ll notice with the 5T is its bit 6.01-inch Full HD+ AMOLED display with an 18:9 aspect ratio. This makes the device look more in line with other 2017 devices, especially because its predecessor came with a more traditional 16:9 screen. The under-the-hood specs are mostly the same as the OnePlus 5’s, but OnePlus decided to switch up the camera setup this time around. Now, in place of the OnePlus 5’s telephoto lens, the 5T sports a secondary 20 MP sensor that uses a fancy new technology called Intelligent Pixel Technology. Basically, it takes better low-light photos than before.

The other big change with the 5T is in regards to biometric security. Not only has the fingerprint sensor moved around to the back, you can also unlock the 5T using face recognition. It’s super fast, but we’ve found it to miss a handful of times for some unknown reason.

The OnePlus 5T is one of the best phone battery life devices, with up to a full day on a signal charge of its 3,300 mHz battery. Perhaps the biggest missing feature on the 5T is an IP rating for dust and water resistance, which is a feature pretty much every other flagship device has. If you can get past that, the OnePlus 5T will be a great option for most people— especially because it costs a fraction of the price of most competing smartphones.

Specs

  • 6-inch AMOLED display with 1,080 x 2,160 resolution, 401 ppi
  • Octa-core Qualcomm Snapdragon 835
  • 6/8 GB of RAM
  • 64/128 GB of on-board storage, microSD expansion up to 256 GB
  • 20 MP and 12 MP rear cameras, 16 MP front camera
  • Non-removable 3,300 mAh battery
  • Android 7.1.1 Nougat
  • 156.1 x 75 x 7.3 mm, 162 g

 Razer Phone

phone battery life

Razer, who have already been highly successful with their wide ranging of gaming PC and console hardware and accessories, decided they wanted to make a gaming and entertainment oriented smartphone. The result is the recently launched handset that’s simply called the Razer Phone. The fact that it packs in 8GB of RAM shows you they want to make gaming on a phone smoother and better than on a normal device.

Besides 8 GB, the Razer Phone includes a big 5.7-inch display with a 120 Gh refresh rate. That feature can be combined with the phone’s other major feature,  Ultra Motion, which syncs up its GPU with the high  refresh rate, which allows games made for the phone to have silky smooth framerates with little to no lag or graphics tearing.

Besides the display features, the Razer Phone also has a big 4,000 mAh battery, making it one of the best phone battery life performers. It also has the Qualcomm Snapdragon 835 processor, loud twin front speakers with Dolby Atmos support, and more to make it perhaps the best phone ever made specifically for gaming. You can purchase it now from Razer for $699.

Specs

  • 5.7-inch-inch LED display with 1,440 x 2,560 resolution
