These are the Galaxy S8 and S8+ battery packs, can you guess the battery life?
The Galaxy S8 leaks are dropping like flies today, and after we saw it beautifully depicted from all sides, and grasped the exact screen resolution, it is now time to learn about the battery capacities of the 5.8" Galaxy S8, and the 6.2" S8+. The latest tip shows two battery packs, and their model numbers, EB-BG955ABA and EB-BG950ABA, are corresponding with the expected internal codes of the Galaxy S8+ (SM-G955), and the Galaxy S8 (SM-G950).

The capacities are 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 upcoming flagships, and corroborated by a previous S8+ battery snapshot leak. What else can we glean from these two batteries? Well, the cells are made in Korea, not in China this time, and assembled in Samsung's huge factory in Vietnam, where a number of the US phone versions by Samsung usually come from. 

There is another pretty telling detail, though. 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 here are marked 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, it seems, is 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, it all depends on how frugal will the new 2960x1440 pixels AMOLED display and the new 10nm Exynos or Snapdragon chipsets be, so there is at least some mystery still left around Samsung's upcoming flagships. Can you take a wild guess about screen-on time out of these capacities?

I get 8 to 10hrs of SOT on my 3300mah A7(6). So I guess may be 5 to 6 hrs SOT.

People here are fooled by the 5.7"-5.8" craze, and don't realize that a 5.7" 18:9 screen actually has roughly the same screen area as a 5.5" 16:9 screen (12.92 vs 12.99 square inch). Battery life of the S8/Plus will not suffer unless the Snapdragon 835 is a fiasco like the 810.

Only the S8+ will have a 6.2-inch screen with 3500mAh battery. And the S8 has a 5.8-inch screen with 3000 mAh battery.

The Note 7 had average battery life with a smaller screen than the S8+ and the same battery size. That's all i need to know that this won't be the device I'm looking for. 6 months of screen efficiency gains & a slight decrease in processor power usage will not be enough to match or surpass the S7 Edge's battery life. Looks like I'll be getting an S7 Edge or maybe sacrificing waterproofing and getting a Mi5S or something

The note 7 had faulty batteries and had a processor with poor efficiency(SD820). What else did you expect? Even phones with large batteries and SD820 don't perform that well in battery life.

On a serious note in spite of the 10nm Processor and perhaps a more efficient display panel. I'm predicting either same battery life as the Galaxy S7 or worse(More likely).

Will wait until these are in hands first to pass judgment on battery stats...

^^ But, the iPhone 8 has had a few leaks touting it's OLED display and other stuffs. The iPhone 8 isn't going to be launched anytime soon, so it's but normal that it's leaks aren't as frequent as the Galaxy S8 which will be announced a week from now.

8-11 hours of on screen time for the 8+ would be my guess. Between the massive improvements in the chip and elsewhere, I'd expect it to have class leading battery. Make that even longer if we can drop the resolution to 1080(ish.. its got an unusual ratio remember).

Samsung please put the screen resolution to 1080p just put more 18.9 screen ratio in put brighter screen, it increases battery life 2k screen resolution is no use of in smartphones
