A round watch face isn't the only throwback in Motorola's Moto 360, as a teardown of the new smartwatch has revealed a four year-old Texas Instruments processor.
According to iFixit, the Moto 360 uses a TI OMAP3630, the same chip that Motorola used in 2010 smartphones such as the Droid X and Cliq 2. Motorola also used the chip in its MotoACTV fitness tracker the following year.
While Motorola's official spec sheet lists a “TI OMAP 3” for the Moto 360, it doesn't specify the exact model. The teardown proves that the Moto 360's processor is a relic that even Texas Instruments has left behind, as the company shifted focus away from mobile devices two years ago.
It's unclear why Motorola reached so far back for the Moto 360's processor, especially since the TI OMAP3630 uses a 45 nm manufacturing process. Ars Technica points out that the TI chip is likely more power hungry than modern mobile chips that use a 23 nm process, which may explain why other Android Wear watches can last longer on a charge.
It doesn't help that the Moto 360 appears to have a smaller-than-advertised battery inside. While Motorola's Website claims that the smartwatch has a 320 mAh battery, iFixit found a 300 mAh battery instead. We've reached out to Motorola to clarify the discrepancy.
Update: Motorola says the Moto 360 has a typical battery capacity of 320 mAh, and a minimum capacity of 300 mAh. Most electronics batteries list both of these numbers, with the higher one being the "official battery size," but the Moto 360 only had room to list one number, and Motorola chose the smaller of the two. "We see how this can be confusing and we will look into ways to add the typical capacity as well in the future," the company said.
Battery issues aside, iFixit noted that the Moto 360 is difficult to repair, as it uses lots of adhesive to hold its tiny layers together. At least the watch band is easy to replace with small tweezers—though Motorola still recommends leaving that job to a professional.
