Exynos 5 Octa powered Samsung Galaxy S4 I9500 Battery Tests Completed
When Samsung first announced their 8 core Exynos 5 Octa processor we were quite enthusiastic. Imagine, a more powerful processor that combines best of class performance with great power efficiency. The fact that Samsung have used both this processor and the Qualcomm Snapdragon 600 in their Samsung Galaxy S4 means that we can make a more focused comparison between the two processors. On one hand, the Exynos 5 Octa has already proven that it is more powerful, however, does it achieve what it initially claimed, as in better power efficiency? Check out the graphs below:
Unfortunately, in all of the graphs for the three main activities of talk time, web browsing and video playback the Exynos 5 Octa powered Samsung Galaxy S4 I9500 does worse than the Qualcomm Snapdragon 600 powered I9505. The most notable is talk time with about 7 hours difference between the I9500 and the I9505. We're hoping that this is because the firmware is still not good enough at knowing when to switch between the two quad-cores in the Exynos 5 Octa as this also happened with early GPU switching technologies like NVIDIA's Optimus. While the comparison is very surprising, the I9500 remains one of the better smartphones out there as it still provides better than average power efficiency compared to other similar brands.
