Galaxy S5 might sport new type of 2,900 mAh battery, March unveiling confirmed again

Today’s rumors regarding the highly anticipated Samsung Galaxy S5 focus on its battery and once again talk about an event in March being the official avenue for its introduction to the world.

Past rumors have given us a purported list of specs for the superphone, but have for some reason remained mum on the battery capacity. According to some tips received by Phone Arena though, it looks like it’s going to be a 2,900 mAh unit. Furthermore, it’s said to use a new kind of battery technology, and come with fast charging times.


The new battery tech, pioneered by a startup called Amprius, allows storing about 20% more energy in the same footprint as ‘normal’ Lithium-Ion batteries currently being used by smartphone makers left and right. This happens thanks to the use of a silicon anode instead of the now-standard graphite (carbon).

So the battery size may stay the same in the Galaxy S5 compared to the Galaxy S4, but we’ll see a bump in capacity from 2,600 mAh to 2,900 mAh. If you do the math based on that advertised 20% energy storage increase, you’ll find that the Galaxy S5’s battery may actually be smaller in size to the one in the Galaxy S4, while bringing us more juice.

This new battery is said to charge in less than two hours, but that may not have anything to do with the aforementioned new tech. The Samsung Galaxy Note 3 uses a USB 3.0 connector and thanks to that it charges its 3,200 mAh battery in around two hours too. So Samsung may, not at all unexpectedly, simply use a USB 3.0 connection for the Galaxy S5 as well, which allows for more power to be drawn in compared to the USB 2.0 standard that all the other makers of Android mobile devices still use.

Going with a capacity of 2,900 mAh doesn’t actually sound like Samsung at all, though. This is one company that loves to one-up its competitors in terms of the raw specs it packs into its high-end devices, after all. The Galaxy S4 came with a 2,600 mAh battery at a time when its only immediate competitor, the HTC One, sported a 2,300 mAh cell. In the meantime, though, both Sony and LG have launched new flagships that have 3,000 mAh batteries – the Xperia Z1 and the G2. Coming out half a year after those with a device that has a lower capacity wouldn’t do good things for Samsung’s obsession with spec sheet comparisons – then again, the company may have simply outgrown such compulsions.

Amprius’ battery tech can apparently be manufactured using existing equipment, according to ExtremeTech, so using that would make sense.

Finally, with MWC fast approaching we hear more and more mumblings that contradict some rumors from last year, when Samsung was said to rush the Galaxy S5 to market thanks to lower than anticipated sales of its predecessor. The new handset was apparently going to be unveiled at MWC with a release soon after. These rumors never seemed plausible, if only because it’s been a very long while since Samsung announced anything of note at MWC (think Galaxy S2 times).

In the past few weeks though, we’ve heard from an increasing number of sources that the Galaxy S5 will have its own event in March or April, followed by availability in April or May. This has been once again confirmed by a “senior official” from Samsung Electronics to ZDNet Korea – namely that the S5 will be announced in March in New York.

London was another city that we heard would get such an event, but Samsung may in fact do both at the same time – it wouldn’t be a first for the company.
