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 P20 Pro

The Huawei P20 Pro has some excellent hardware specs, including a 4,000 mAh battery, which reviews claim should last most users over 15 hours with a single charge. It has a 6.1 inch display with an OLED panel. The Huawei P20 Pro was the first smartphone released with a triple rear camera setup. In addition to the 20MP monochrome sensor, the RGB sensor on the Pro goes up to a whopping 40MP, and is joined by the third sensor, an 8MP telephoto lens. The Pro also has a five-times hybrid zoom feature.

Inside, there’s Huawei’s in-house Kirin 970 processor, with its NPU chip that adds AI features, including features that help improve taking pictures with their impressive cameras. It’s not cheap, however, as the Huawei P20 Pro costs around 900 euro (about $1100) in Europe. If you want, you can get the international version on Amazon in the US for about $800. There’s also the Porsche Design Huawei Mate RS variant of the P20 Pro that includes a in-screen fingerprint sensor, a 6-inch screen, and you can get one with a massive 512GB amount of onboard storage in Europe for 2095 euro ($2600).
