When I reported on the latest rumored specs for the Galaxy S5 yesterday, one thought kept going through my mind: If the phone does indeed comes with a 5.25-inch “2K” display, it’s going to need one heck of a battery to keep it going. And according to PhoneArena, it just might get one. The site’s sources say that Samsung is planning to use a new type of lithium-ion battery to provide plenty of juice to the Galaxy S5, without needing to increase its size.

For reference, the Galaxy S4 has a 5-inch, 1080p display and a 2600mAh battery. Based on the rumors, the Galaxy S5 might have a 5.25-inch, 2K display and a 2900mAh battery. When you take into account the higher resolution and larger display size of the GS5, I think the increase in battery size will ultimately result in a wash. But I don’t think that’s a bad thing: The Galaxy S4 has pretty good battery life, so if Samsung is able to deliver the same results in a phone with a bigger, sharper screen, I think that would be good enough to make most users happy.

Also interesting is the type of battery Samsung is rumored to be using. According to PhoneArena, the company might employ a new type of lithium-ion battery that’s capable of storing 20% more energy than an older battery with the same footprint. This would allow Samsung to fit those extra 300mAh of power in there without needing to increase the size of the battery or the phone. And it could feature rapid charging technology, which would let you reach a full charge in just two hours.

Of course, none of this has been verified by Samsung, though it makes sense to me. But with an announcement likely two months away, there’s sure to be plenty more speculation until then.
