Samsung’s Galaxy S4 is half a year old now, which doesn’t sound like a lot, but in the mobile industry that’s considered an eternity. Now normally Samsung holds an event in March or April to announce their new flagship Galaxy S phone, but according to the Korean publication ETNews, 2014 is going to be different.

The site says that Samsung wants to have the Galaxy S5 on store shelves by the end of Q1. Said phone will have a 5.0 inch 1080p display, similar to the Galaxy S4, but under the hood it’ll have a gigantic 4,000 mAh battery. To put that into some perspective, the 5.7 inch Galaxy Note 3 has a 3,200 mAh battery.

Known internally as “Project K”, the Galaxy S5 will allegedly come in two versions. One will be made out of metal and have a 64-bit Samsung chip inside. That’s probably going to remain exclusive to South Korea. The other GS5 variant, the one that’ll launch all over the world, will have a Qualcomm chip and be made out of plastic. Both versions will have a 16 megapixel camera, probably with optical image stabilization, 3 GB of RAM, and will run Android 4.4 KitKat.

How credible is this rumor? I tend to trust ETNews, but I’m having a hard time imaging how in the world Samsung will be able to make a phone with a battery that large. The launch date I can believe, and the site also says that Samsung will produce 70% as many Galaxy S5 units as they did the Galaxy S4 because the high end market isn’t as strong as it once was.

We’ll just have to wait and see. March is just three months away.
