This month we removed the Huawei Mate 8 to make room for the BlackBerry KEYone.

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 even how much storage space it has. Let’s not forget about that battery though. For those that need great battery life, battery performance is one of the most important considerations before buying.

Battery technology has come a long way 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 20 Pro

The Huawei Mate 20 Pro is nothing short of impressive in many senses, but it is especially great when it comes to battery life. Packed inside is a 4200 mAh battery, which is not huge, but the Chinese manufacturer has done a great job making the most of it. 

During our tests we managed to get six to seven hours of screen-on time with heavy usage. Most importantly, the phone can be charged stunningly fast. Huawei says its goes from zero to 70 percent in 30 minutes, but in our testing we sometimes found it to be even faster. 


  • 6.39-inch curved OLED 16:5:9 display 3,120 x 1,440 resolution
  • Octa-core Huawei Kirin 980 processor
  • 6GB/8GB of RAM
  • 128GB/256GB of on-board storage, NM card slot
  • Triple 40, 8 and 20MP rear cameras, 24 MP front camera
  • Non-removable 4,200 mAh battery
  • Android 9.0 Pie
  • 157.8mm x 72.3mm x 8.6mm, 189 g

Oppo R17 Pro

The Oppo R17 Pro may be hard to find in North America, but if you are concerned with battery life and fast charging smartphones, you might want to grab it. This phone actually has two 1,850mAh batteries inside, making it into a 3,700mAh battery. This is supposed to boost the battery’s charging time, and in our tests, we saw the Oppo R17 Pro charge up to 96 percent of its capacity in just 30 minutes, via the company’s in-house via SuperVOOC Flash Charger. In terms of use, we got over a day’s worth of work on the phone with a single charge.

The Oppo R17 Pro has a Qualcomm Snapdragon 710 processor, but the rest of its hardware specs could be found on higher-end flagship phones, including 8GB of RAM, 128GB of storage, a triple camera setup with 20MP, 12MP and a “3D Stereo” camera, along with a 25GB front-facing camera, and a big 6.4-inch AMOLED 2,340 x 1,080 resolution display with a waterdrop notch. Once again, if you can get it, the Oppo R17 Pro might be worth checking out.


  • 6.4-inch 2,340 x 1,080 resolution display
  • Qualcomm Snapdragon 710 processor
  • 8GB of RAM
  • 128GB of onboard storage
  • Android 8.1. Oreo
  • 12M, 20MP and “Stereo 3D” rear cameras, 25MP front-facing camera
  • Two 1,850mAh batteries, that work like a 3,700mAh battery
  • 157.6 x 74.6 x 7.9mm, 183 g

Moto G7 Power

The Moto G7 Power comes with a nice $249.99 price point and modest specs. It may not be competing with the high-end beasts, but those who treasure battery life will value its type of “power” more. It sports a massive 5,000 mAh battery! 

Paired with non-resource-intensive specs, that battery should make wonders, and we must say we have been very pleased with our tests. In our review Lanh mentions he could get 2-day battery life and easily reached the 10-hour screen-on time threshold. Not bad at all! 


  • 6.2-inch LTPS LCD display with 720 x 15200 resolution
  • Qualcomm Snapdragon 632 processor
  • 3 GB of RAM
  • 32 GB of on-board storage, microSD expansion up to 512 GB
  • 12 MP rear camera, 8 MP front camera
  • Non-removable 5,000 mAh battery
  • Android 9.0 Pie
  • 159.43mm x 76mm x 9.3mm, 198g

The Samsung Galaxy Note 9 finally gets a boost in battery size compared to other models, as it gets a 4,000mAh battery. Our tests show that it will give most folks over a day of use when fully charged.

It manages to handle this even with its big 6.4-inch Super AMOLED display that shows off video and image content to the highest degree. It’s got a fast processor inside (either the Qualcomm Snapdragon 845 or the Samsung Exynos 9810). It has plenty of memory (6GB or 8GB of RAM) and tons of onboard storage (128GB or 512GB).

The Note 9’s dual rear camera takes excellent pictures. The embedded S-Pen has added functionality this time, including remote control support. Even the Note 9’s battery gets an upgrade to 4,000mAh, which means you can work longer on a single charge. It may be expensive, but if you want the best all-around Android phone, with some excellent battery usage, the Samsung Galaxy Note 9 can’t be beat.

Samsung Galaxy S10 Plus Back Red (6 of 9)

Not a fan of the Note 9? You might want to check out the Samsung Galaxy S10 Plus, which offers a similar size and battery prowess. A 4,100mAh battery may not sound great in 2019, but it seems Samsung can do plenty with it. In our tests we found it would easily reach six to eith hours of screen-on time and we never managed to kill it in a full day of usage. 

The Samsung Galaxy S10 Plus is a powerhouse, so it is not only one of the best in terms of battery life, but it is a great performer and overall enjoyable device. If you are willing to pay the $999.99 starting price, that is.

OnePlus 6T

The back of the Thunder Purple OnePlus 6T.

OnePlus has another winner with the OnePlus 6T, which offers well over a day of use with a single charge of its 3,700mAh battery, an upgrade compared to the OnePlus 6 with its 3,300mAh battery. It manages to do this even with its big 6.41-inch Super AMOLED display with a small waterdrop notch.

This phone also has the latest and greatest specs available: a Snapdragon 845 SoC, 6 or 8GB of RAM, and up to 256GB of storage. The cameras include dual 16 and 20MP sensors around back with f/1.7 apertures. You can get the unlocked OnePlus 6 starting at just $529 for the model with 64GB of storage and 6GB of RAM. That’s not a lot to pay to get one the best performing phones around. You can also go all out and get the OnePlus 6T McLaren Edition, which has 10GB of RAM, 256GB of storage, and a special 30W “warp charge 30” charger that gives the phone’s battery a full day’s worth of use in just 20 minutes. All of that for the very reasonable price of $699.
