Last year, Apple released its own wearable device, the Apple Watch. It did so in order to increase overall sales and make its product line more varied. Unfortunately, sales for even the wearable have declined dramatically since the release.

According to Bloomberg, 1.6 million smartwatches from Apple were released from April to June of this year. And while this is not a bad number in itself, it is less than half of the units sold in April to June of 2015. The publication goes on to report that several network carriers have urged Apple to make the Apple Watch available to other data networks other than the iPhone. As it is, of course, the Apple Watch can only be synced via an iPhone.

Theoretically, the Apple Watch would be able to download different alerts and updates, as well as email without having to reply on the iPhone. Likewise, the wearable would be able to connect via 3G or 4G and link directly to the users' networks. Unfortunately, Apple has recently admitted in a discussion that this feature will not be available for the upcoming models.

The reasoning is that, currently, the cellular chips consume too much battery - one that the Apple Watch cannot supply at this point. However, the company did confirm that it is looking into other cellular data chips that use less power, for future smartwatch units.

What is expected of the upcoming wearable, however, is a FaceTime camera. According to The Week, a small camera will rest on top of the bezel, which would allow wearers to answer calls from their wrists.

The design, on the other hand, will show a thinner unit, about 20 to 40 percent less than the current smartwatch. But other than this, there will be not much of a redesign to the Apple Watch.
