We already know that the Samsung Galaxy S8+ is an incredible phone: it has the stunning, futuristic design, it has the camera and it has the performance, but how does it do in terms of battery life?
After all, the Galaxy S8+ has the tough task to deal with a large, 6.2-inch display and it has a very powerful system chip (for this test, we have the Exynos 8895 version of the S8+, we will test the Snapdragon 835 model at a later point in time), both factors that could potentially consume a lot of power.
To find out about the Galaxy S8+ battery life, we put it through our standard test that allows us to compare all phones on equal grounds: with the screen set to the same level (200 nits of brightness, comfortable for typical indoor use). Luckily, the Galaxy S8+ does very well in this test and even though it is not the number one battery performer, it is certainly above the average for flagships these days. Note that we have tested using the Full HD+ resolution that our phone came set to by default (1080 x 2220 pixels).
The Galaxy S8+ battery life test result stands at exactly 8 hours. Compare this with the 7 hours and 18 minutes that the already very good Galaxy S7 Edge scored, and you see that Samsung has managed to improve on their last year's phone. The S8+ also bests the Google Pixel XL, the OnePlus 3T, but falls a bit short of the battery life on the iPhone 7 Plus.
In a nutshell, the Galaxy S8+ and its 3,500 mAh battery turn out to be a very good combo. Despite fears that a 3,500 mAh cell might not be sufficient to guarantee a solid battery showing, we see that Samsung has managed to do quite well.
On a separate note, we have recently noticed that more affordable phones, especially ones with the 14nm Snapdragon 625 system chip, do remarkably well in terms of battery life. The Galaxy S8+ has a much more powerful processor, however, and a higher resolution to handle, so it does not quite get into that coveted two-day battery life territory. Still, when we speak about flagship grade devices, the Galaxy S8+ is definitely among the best out there. With a phone like this, you can be assured that you will get through a busy full day and still have juice left, even if you are a power user, and that is definitely reassuring.
