Dual Chip Bluetooth Calling on Smartwatches

Dual Chip Bluetooth Calling smartwatches features the Bluetooth 5.0 version which is used for connectivity and data synchronization whereas, the same watches also come with another Bluetooth chip which generally is Bluetooth 3.0 and this is used to make make and receive calls.

Because the watch has a dual chip inside, one is for connectivity and the second is for Bluetooth calling, hence it’s called Dual Chip Bluetooth Calling.

Also, as the watch has dual chips, it will consume more battery along with that, and there will be lots of issues in connectivity as well.

The moral of the story is, Dual Chip Bluetooth Calling on Smartwatches is not a good ideal option, especially for Bluetooth calling.

Single Chip Bluetooth Calling on Smartwatches

Single Chip Bluetooth Calling on Smartwatches

Smartwatches with Single Chip Bluetooth only have a single chip which will be Bluetooth 5.2 or higher. The tech is still new and we’re yet to see the single-chip Bluetooth calling in budget smartwatches, still, we do have some good options above 3k.

Again, there is no need for a second chip, everything is performed in a single chip because of this, the watches provide longer battery life, stable connection, and even better range.

Which is Better Dual chip or Single chip smartwatch

Dual chip vs Single-chip Bluetooth

To make it simple, if you use Bluetooth calling feature on a smartwatch a lot then it’s better to get a smartwatch with a single chip but if you don’t care about Bluetooth calling then better get a dual Chip smartwatch as it will be cheaper in price.

As I have said, single-chip Bluetooth makes everything perfect as it’s an updated version of Dual Chip Bluetooth.

For example, Single Chip Bluetooth provided longer battery life, stable connection, and a lot more whereas Dual chip Bluetooth doesn’t provide the same as its used dual chip at the same time for everything.
