Samsung introduced the functionalities of the Gear 2 series at Barcelona’s MWC2014. Which makes sense as most people buy gadgets and tools to use them: The nitty gritty doesn’t really interest them. We like the functionalities as well but even more what’s under the hood. More specifically: Why is there such an increase in battery life when compared to the Gear 1?
It did take some time and some research but now the hood came of! Like the original Gear the newlings are using an Exynos processor: one that basically could handle two cores at 1Ghz, which might be seen as juice-guzzlin’ overkill for the first gear. So the technicians curbed it by downclocking and set it to a single processor to maximize time between charging. For the gear 2 the smart people at Samsung used an updated version, the Exynos 3250 in the second series of the Gear: No more downclocking and using both cores this time. At the same time they are enabling a battery life that will make the customer happy! Faster, two cores and yet less power consuming? What has happened?
What would you expect at Tizen Experts? Indeed, it’s Tizen powered and no longer by an Android version. Removing the system overhead created by Dalvik relying on a lean Linux core have helped achieve this.
Gear Fit
Third sibling of the second generation is the Gear 2 Fit (non-Tizen device). Here it is the size that matters. A small and, quite unobserved, curved AMOLED powered by the Cortex-M4 STM32F439. Which, with a simplified OS packs enough power to make the Gear Fit a tool that fits into a fitter life.It comes with it’s own accelerometer, gyroscopic tool and a heart neat monitor. Samsung notes several times that it is no medical device but my GP would like me to use one as part of the training I will start any day now. I’ve not tested it but I’m pretty sure it would hook up nicely to my Note3 and S Health.
