Galaxy S8 and S8+ official battery life stats are in: a mixed bag compared to the S7 and S7 edge


The Galaxy S8 and S8+ are hot of the press, and the exact battery capacities of the 5.8-incher and its larger 6.2-inch sibling are now officially confirmed to be 3000 mAh for the smaller S8, and 3500 mAh for the S8+, which jibes with what we've heard before about the battery compartment of Samsung's fresh new flagships.

The WSJ reported not long ago that Samsung is in talks with Murata to become its third battery supplier for the Galaxy S8 batteries, and, sure enough, the battery packs that leaked weremarked with "Samsung Japan," so the actual design may be coming from Sony's former battery subsidiary that is in the process of being acquired by Murata. Samsung is likely diversifying its battery manufacturing technology, and not taking any chances with the S8 in that regard, after the lessons learned from the Note 7 recall. 

As for the actual battery life out of those two puppies, well, the more frugal tech of the 2960 x 1440 pixels AMOLED display, and the new 10nm Exynos or Snapdragon chipsets have improved the official battery life numbers in comparison with the S7 and S7 edge, but only in certain categories like music playback. For video playback and Internet browsing, the numbers are pretty comparable, while the talk time endurance for the S8 and S8+ is slightly shorter than that of their predecessor:
