Samsung Galaxy S8 and S8+ battery life test result is out
We already know that the Samsung Galaxy S8 and S8+ are two incredible phones: they have the stunning, futuristic design, they have the camera and they have the performance, but how do they do in terms of battery life?
After all, the Galaxy S8 and S8+ both have the tough task to deal with large, high-res displays and they have a very powerful system chip (for this test, we have the Exynos 8895 version of the phones, we will test the Snapdragon 835 model at a later point in time), both factors that could potentially consume a lot of power.
We have tested the Exynos Galaxy S8 and S8+ model
To find out about the Galaxy S8 and S8+ battery life, we put them 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 phones came set to by default (1080 x 2220 pixels).The Galaxy S8 and S8+ get similar, but not equal battery life test results. The Galaxy S8+ Exynos model that we tested scored exactly 8 hours, while the more compact S8 Exynos version topped this with a score of 8 hours and 23 minutes. Interestingly, the Snapdragon model of the Galaxy S8 scored less than the Exynos version: it went 10 minutes short of 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 and S8+ also best the Google Pixel XL, the OnePlus 3T, but fall a bit short of the battery life on the iPhone 7 Plus.
The Galaxy S8 and S8+ battery will last you through even a very busy day
In a nutshell, both the Galaxy S8 with its 3,000 mAh cell, as well as the S8+ with its 3,500 mAh battery run a long time.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. In fact, we often get envy-worthy 2-day battery longevity on these phones, while the Galaxy S8 and S8+ are not quite in that 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.
Another important aspect of battery usage is the time it takes to fully recharge a battery from 0 to 100%. The Galaxy S8 and S8+ support Samsung's Fast Adaptive Charging and both phones are able to fully recharge their battery in just 1 hour and 40 minutes. This is not the fastest we have seen, but it is not too far off. The Galaxy S8+ also supports fast wireless charging, which is a neat feature to have.
