According to the latest test results made public by GameBench, the Exynos 8890 powered Galaxy S7 has exhibited a significantly better battery life, in comparison to the Snapdragon 820 version that is available in the US. In fact the difference is enough to surprise you and not in a pleasant way if you are in the US.
You can see all the data in the images, courtesy of PhoneArena, but the end result speaks for itself. Apparently, the S7 Exynos is 71% more power-efficient, as compared to the S7 Snapdragon version! Sadly, it is even the least power-efficient device when compared to two other SD 820 powered smartphones, the LG G5 and the HTC 10. Even though the Snapdragon variant was almost neck-to-neck in terms of audio playback, the Exynos version did beat it in that department as well.
Keep in mind though that the snapdragon variant of the Samsung Galaxy S7 was from Verizon and had the expected bloatware as a result. Nevertheless, the difference in between the two variants is just too great to ignore or blame on the bloatware. We found the disparity to be surprising and disappointing, what do you think?
