Also see: Best Phone Deals We all have our own opinions on which is the best smartphone, as is evident from the comments on our best smartphones 2017 and best Android phones 2017 articles. But this doesn’t mean benchmarks don’t matter. For some people having “the best phone” is important, regardless of real-world usage. As such, we continue to run all smartphones that enter the PC Advisor Test Centre through our usual benchmarks, which look at processing performance, graphics performance and JavaScript performance. These tests include: • Geekbench 4 (processing performance) • AnTuTu 3D (processing performance) • GFXBench T-Rex and Manhattan (onscreen graphics performance) • JetStream (JavaScript performance) • Geekbench 3 battery test (battery performance) * Note that the battery test has been removed from Geekbench 4 In the below bar chart you can see how the flagship phones for 2017 compare in terms of processing-, graphics- and JavaScript performance, plus battery life. If you’re looking for which has the best camera see our separate article on  Best phone camera 2017. We’ve also compared these phones on their audio performance – see  Best audio phone. For more details on the phones themselves and the unique features they offer, read our individual in-depth smartphone reviews: • Apple iPhone 7 review • Apple iPhone 7 Plus review • Google Pixel review • Google Pixel XL review • HTC 10 review • Huawei P9 review • LG G5 review • Moto Z review • OnePlus 3T review • Samsung Galaxy S7 review • Samsung Galaxy S7 edge review • Sony Xperia XZ review • Xiaomi Mi5s review

Keep in mind while browsing our benchmark results that benchmark boosters are real, and there is little we can do about this. Benchmarks should always be taken with a pinch of salt (we’ve seen the same phones giving wildly varying results within minutes of each test), and used as only one factor in your purchasing decision.
