Single Chip vs Dual Chip Bluetooth Calling On Smartwatches

Lately, brands like Noise and Crossbeats have started introducing single-chip Bluetooth calling on their smartwatches. This may create confusion among people looking forward to budget-calling watches. In this article, we’ll clear the confusion by comparing single-chip vs dual-chip Bluetooth calling on smartwatches and which of them is a better technology.

What is Dual Chip Bluetooth Calling on Smartwatches?

Dual-chip Bluetooth calling is quite common on budget smartwatches. These smartwatches generally feature Bluetooth version 5.0 which is used for connectivity and data synchronization. Whereas, the manufacturers use another Bluetooth chip (say version 3.0 or above) for calling purposes.

This is why it is called dual-chip Bluetooth calling. But because of a separate calling chip, you have to pair the watch separately from Bluetooth settings on your phone to be able to make and receive calls. It not only takes time but also consumes more battery life and has frequent connectivity issues while calling.

So if you see a smartwatch brand flaunting dual-chip calling on its watches, take it with a grain of salt.

What is Single Chip Bluetooth Calling on Smartwatches?

Single-chip Bluetooth calling is a relatively new technology in smartwatches. Several brands have introduced some new budget smartwatches with single-chip Bluetooth calling. These smartwatches feature Bluetooth version 5.2 which is used for both calling and connectivity at once and does not require a dedicated calling chip.

It is a superior way of calling as it needs only one chip, has a shorter pairing process, better connectivity, a longer calling range, and low power consumption. Also, it does not require much additional cost.

Single Chip vs. Dual Chip Bluetooth Calling

Here is the comparison between single-chip and dual-chip Bluetooth calling on smartwatches:

Single Chip Bluetooth Calling

Dual Chip Bluetooth Calling

One Step Pairing

Three Step Pairing

Low Battery Consumption

High Battery Consumption

Higher Calling Range

Lower Calling Range

More Stable Connectivity

Unstable Connectivity

No Delay in Calling

Little Delay in Calling

Fun Fact: Because of a dedicated calling chip in the dual-chip smartwatches, we can use them as Bluetooth speakers and transfer the full audio of our phone to the watch. Check this article to use this trick!

Which is Better?

Single-chip Bluetooth calling has many advantages over dual-chip technology like better connectivity, higher calling range, easy and fast pairing, better-calling experience, and low battery consumption. And it clearly wins over dual-chip Bluetooth calling.

Single-chip Bluetooth calling is the future of smartwatches, especially budget ones. And if both are available at a similar price, then we would recommend getting the single-chip calling smartwatch if calling is a priority.

However, if you don’t use the Bluetooth calling feature on a smartwatch, then it would be best to pick the one that suits your budget and other specification requirements.
