How Far Can Apple Watch Be From iPhone And Remain Synced?

Apple Watch is known for its premium hardware, and the company also uses the best components to ensure that Apple watch offers the best performance.

However, today’s question is: How Far Can Apple Watch be from iPhone and remain synced? Let’s find the answer.

Apple Watch mainly uses Bluetooth to establish a connection with the iPhone.

Now when it comes to range, it mainly depends on the version of the Bluetooth as different versions have their own range, but there are factors too, which can affect the range of Bluetooth.

Let’s take a look at the range of the different Bluetooth Versions and which factors affect the range.

How Far Can Apple Watch Be From iPhone And Remain Synced?

If we look at the general range, the Apple watch can remain in sync with the iPhone within the 50 to 70 feet, but it can change depending on which version of the Apple watch you have.

So, let’s look at the range of each Apple Watch, and it will give you a better idea.

Bluetooth Range of Apple Watch Series 5

Apple Watch Series 5 comes with the Bluetooth 5.0 chip, which can easily connect up to 400 meters in normal circumstances. If you are in an apartment with a lot of walls, then the range can be affected, and it can reduce to 300 meters or even less depending on the number and thickness of the walls.

Similarly, if you are in an outdoor area with no objects around, then you get the range of around 1000 meters. So, your Apple watch can remain in sync with your iPhone if they have a distance of 1000 meters between them.

Bluetooth Range of Apple Watch Series 4

Apple Watch Series 4 also comes with Bluetooth 5.0 chip, which allows the Watch to remain sync with iPhone up to 400 meters indoors and around 1000 meters outdoor.

Bluetooth Range of Apple Watch Series 3

Apple Watch Series 3 comes with Bluetooth 4.2, which is the much older version and comes with a very limited range. In the apartment with a lot of walls, the best range you can get is around 40 to 50 meters. If the walls are thicker or the number of walls is higher, you can experience connection issues as well.

If you use the Watch outdoor, you can get the range of only 100 meters, which is 10 times lower than the Apple Watch Series 4 and 5.

Bluetooth Range of Apple Watch Series 2

Apple Watch Series 2 comes with the Bluetooth 4.0 version, which is not very powerful, and it can only offer the range of up to 50 meters indoors. Just like 4.2, you can experience the connection issues if there are a lot of walls in the apartment or walls are very thicker.

The outdoor performance of Bluetooth 4.0 is also very promising, and you only get the range of up to 100 meters, which is not good considering the modern standards.

Bluetooth Range of Apple Watch Series 1

Apple Watch Series 1 also comes with Bluetooth 4.0, and just like the Apple watch series 2, you get the indoor range of up to 50 meters and outdoor range of 100 meters.

Can My Apple Watch Stay Connected With Iphone If The Bluetooth Connection Is Interrupted?

Apple Watch uses Bluetooth for its connection with the iPhone, but if the Bluetooth connection gets interrupted or you go out of range, then the Apple watch can use the cellular network to connect with your iPhone.

However, you will need to have the Cellular version of the Apple watch.

If you don’t have the LTE Apple watch and your Apple watch only has the Bluetooth connection, then there’s no other way to connect with the iPhone.

So, your Apple watch will wait for you to get into the range of Bluetooth, and then it will connect with the device.

Which Factors Can Affect The Bluetooth Range Of Apple Watch?

When it comes to Bluetooth, it uses waves to send the data and communicate with the connected device, and the Apple Watch is no exception.

The Bluetooth chip in the Apple watch also uses the same mechanism to communicate with the iPhone, but there are some factors that can affect the range. Let’s take a look at them.

  • The major factor which affects the Bluetooth range is the obstacles, i.e., walls, trees, metal objects. For example, if you are in an apartment with a lot of rooms and let’s say that you are in the 5th room and your iPhone is in the 1st room. Depending on the number & thickness of the walls, the range of Bluetooth can get affected and reduced.
  • You may know that every electronic device has its own electromagnetic field, and this field can vary depending on the power of the device. For example, a laptop will have a bigger and powerful electromagnetic field as compared to one from a smartphone. So, if your apple watch is near a device with a stronger electromagnetic field, then the Bluetooth waves can get interrupted, and they can affect the range.
  • Similarly, if the distance between the Apple Watch and your iPhone is higher, the power of the Bluetooth signal can get affected.
  • If there’s a router near your Apple watch, then it can also affect the Bluetooth signal as it constantly receives and emits the waves for communication with connected devices.
