Samsung's Free-form Battery Is The Secret Behind The 250 MAh Pack In The Gear S2

Samsung can already be considered a veteran by smartwatch standards with a few generations of wearable products behind its back. The recent Gear S2, however, represents the tech giant's brecent first step into the newer round watch market.

One of these clever recent technologies that went into the recent wearable is Samsung SDI's free-form battery. As it appears, it was instrumental to fitting as much juice inside the Gear S2 as possible within the limited space.

In this case, the device is equipped with a 250 mAh free-form pack, which might not sound like much, but is a whole 50 mAh more than the 200 mAh that a rectangular battery would have allowed. At this scale the extra juice is vital and ensures what Samsung claims to be up to three full days of battery life.

Samsung SDI actually started work on the free-form project in December 2014 and made quick progress with a final version in April and mass-production in August. That is a truly impressive development cycle and it is always astonishing to see how quick industry leaders can push a concept all the way to an actual consumer product with tangible benefits to the user. So, even if the Gear S2 doesn't turn out to be a grand market success, it does still represent a significant technological step forward.
