Galaxy S5 might sport a new type of Li-ion battery with 2900 mAh capacity and rapid charging16
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 could be similar to the one we told you about recently, coming from Stanford research. It uses silicon for the electrodes instead of the typical graphite ones, which allows a significant increase in capacity. 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.
Thanks for the tip!
