Battery life is one of the most important things to consider when buying a new phone. But how do you want to know how each phone's battery stacks up against another? Fortunately, we've put the best phones on the market – especially OnePlus 6, LG G7, Galaxy S9 Plus, iPhone X, Google Pixel 2 XL and Huawei P20 Pro – for the ultimate test.
Each phone was set to the same brightness, connected to the same Wi-Fi network, and ran the same social media accounts. Instead of using the Nyan Cat video as we usually do in testing, we decided to introduce different variables to reflect how we actually use our phones.
We started running a 30-minute video game, leaving each phone with at least 91 percent battery life (P20 Pro was 94 percent). Then we took up the "Explore" section of Instagram for one hour, which contains constant video. IPhone X spoke management by 87 percent, while the LG G7 fell rapidly to 77 percent. Since we often use our phones to get around and watch videos, we also drove Google Maps on every phone for 30 minutes and recorded a video of 30 minutes, 1080p. Each device was still over 50 percent after two and a half hours of testing, but the LG G7 was 52 percent last.
After playing two hours of video on YouTube, Huawei maintained the lead by 56 percent and the LG G7 fell to only 25 percent battery life. It took an hour to surf the web, an hour to see Facebook's automatic game viewing page, and an additional two hours of streaming on SoundCloud for the first phone to die. Six hours and 45 minutes in, the LG G7 was the first to fall. Once out, we decided to stay with YouTube for the rest of the test.
