The latest report says the update to the popular Android phone line could include a new kind of lithium ion battery that holds 20 percent more energy in the same size module as the Galaxy S4 battery, and also carries a rapid-charging technology that will get you powered up in less than two hours.
PhoneArena says its sources claim that the battery for the S5 will be 2900 mAh, an increase from the Galaxy S4's 2600 mAh juice pack. The increase might not necessarily boost the overall battery life of the S5, however, if reports that it will come with a high-resolution 2,560x1,440-pixel AMOLED display pan out.
So far, the collected reports and rumors point to high-end specs for the Galaxy S5, including the possibility of a Snapdragon 805 processor, which has advanced graphics performance over its predecessors; the aforementioned 2K display; a 16-megapixel camera; and a premium metal-body model.
We're also hearing rumblings about some new features like head tracking and a possible iris scanner, things that could also make use of a bigger battery.
