Early indications suggest that Samsung's Galaxy S8+ is one amazing device. Its 6.2-inch OLED screen has come in for particular praise - DisplayMate called it the most innovative and high-performance smartphone display ever tested. But does its brilliance come at the cost of short battery life? Apparently not.

PhoneArena has been testing the Galaxy S8+ against other popular smartphones. It found that Samsung's handset came second on the overall list of flagship devices, beating many of the other larger handsets but still a fair bit behind the iPhone 7 Plus. All phones were tested with their screen brightness set to 200 nits. The Exynos 8895 version of S8+ is used, with the resolution set to 1080 x 2220.

The S8+ manages exactly 8 hours of battery life, putting it ahead of its S line predecessor - the S7 Edge - by 42 minutes. The new handset pushes the iPhone 7, which has a 1960 mAh battery, out of second position, beating it by 14 minutes.

Apple still boasts the device with the longest life. Lasting 9 hours and 5 minutes, the iPhone 7 Plus beats the S8+ by quite a margin, though the iPhone does have a much smaller display. Nevertheless, Samsung's phone, which boasts a 3,500 mAh battery, is ahead of competitors such as Google's Pixel and the Huawei P10.

One area where the S8+ has many of its rivals beat is charging time. With Samsung's Fast Adaptive Charging support, the handset can fully recharge from 0 to 100 percent in 99 minutes, much quicker than the 197 minutes it takes for the iPhone 7 Plus to fully juice up.
