You know what the Galaxy S5 needs? More Power! Well, maybe it doesn't need more power, but it's getting more. The company has posted a product page for the Galaxy S5 Plus, a variant of the current flagship that includes a Snapdragon 805 in place of the 801 that powers most current variants.
Samsung released the first 805 version of the GS5 earlier this year in Singapore (the Galaxy S5 4G+). The device has a quad-core snapdragon 805 clocked at 2.5GHz, a little slower than the chip in the new Note 4. Now that the product page is going up, it looks like Samsung is ready to expand this device to more markets (live in the Netherlands so far).
Other than the boosted CPU spec, this is the same device that already exists. That's probably a good thing, though. The continued use of 1080p ensures the device will be even snappier than the original and previous buyers don't have to be too jealous. The new hardware should also support LTE speeds as high as 225Mbps, but good luck actually finding that.
