Additionally, the latest rumor puts the kibosh on earlier talk that the Galaxy S6 edge+ would be powered by the Snapdragon 808 SoC. The word from this anonymous source out of Vietnam, is that the same Exynos 7420 chipset employed by the Samsung Galaxy S6 and Samsung Galaxy S6 edge will be under the hood of the Galaxy S6 edge+. In addition, the chip could be set to a faster clock speed than the 2.1GHz that is used on the two older models. The rumor also mentions that the Samsung Galaxy S6 edge+ will feature a 3000mAh battery.
Considering that this information is coming from an anonymous source, it would be a good idea to take this story with a pinch of salt. We could see the Samsung Galaxy S6 edge+ and the Samsung Galaxy Note 5 both unveiled next month, and that is when the truth will finally come out.
