Galaxy S5 might sport a new type of Li-ion battery with 2900 mAh capacity and rapid charging

We've been getting tips about the alleged battery capacity in the Samsung Galaxy S5, claiming it will be 2900 mAh, with rapid charging technology deployed, which will get the juicer pumped up to the rim in under two hours.

The Galaxy S4 has a 2600 mAh battery, so a 2900 mAh unit would be a nice bump in capacity, unless, of course, it has to maintain a 2K resolution display panel, then we'll probably hardly see any gain in battery life from the fourth generation to the fifth.

The interesting thing is that our tipsters claim it will be a new type of Li-ion battery that can store 20% more energy in the same footprint, so despite the bump in capacity, the battery size might stay the same, meaning more place for internals, and/or a more compact handset. The new technology in question is the one we told you about recently, coming from Stanford research. It uses a silicon anode instead of the typical graphite one, which allows a significant increase in capacity.

The type of battery that will supposedly be in the Galaxy S5, is commercialized by Amprius, a Silicon Valley startup, which says it can be produced with current technology, and is already in hundreds of thousands of electronics devices, shipping now also to "some smartphone makers". Not a bad deal if we get a 2900 mAh unit in the Galaxy S5, while it keeps the same compact frame as its predecessors.
