Samsung's new flagship Galaxy S8+ comes with a bunch of power-packed features including the 6.2in QHD+ Infinity Display and a substantially larger 3500mAh battery as opposed 5.5in IPS LCD with a 2900mAh battery on the iPhone 7 Plus. Although the S8+ has superior specs on paper, its battery life falls short by more than an hour in comparison to the iPhone 7 Plus.
The iPhone 7 Plus mostly benefits from Apple's better optimised software while the Android-based Galaxy S8+ comes second best in Phone Arena's recent battery-benchmark test. The former lasted for around 9 hours and 5 minutes while the latter could survive for just 8 hours in the custom web-script based battery test mirroring the actual power usage of a real world scenario with the display brightness set to 200nits on both the test smartphones.
It must be noted that the iPhone 7 Plus is six months older than the Galaxy S8+, but still the former does well in terms of battery performance. However, Galaxy S8+ stands out for its bigger display as well as quick and wireless charging capability.
In contrast, the Google Pixel XL and Galaxy S7 Edge showcase similar battery endurance capabilities at 7 hours and 19 minutes, and 7 hours and 18 minutes respectively. The OnePlus 3T finishes in the last position with a battery endurance score of 5 hours and 41 minutes.
