The differences between Huawei Watch GT 2 and Huawei Watch GT 2e

Huawei has recently launched the Huawei Watch GT 2e which priced about 30% cheaper than the flagship Huawei Watch GT 2.

While Huawei Watch GT 2 comes in 2 case size variants of 46mm and 42mm, the Huawei Watch GT 2e only has one case size, which is 46mm.


There are a lot of similarities in the specifications between Huawei Watch GT 2 and Huawei Watch GT 2e. Many people has been asking, beside the obvious different in price tag, what are the differences between both of them?

After some fact finding, I have concluded that the Huawei Watch GT 2e is a model with features and functions in-between the 46mm and 42mm variants of Huawei Watch GT 2.

The main differences of Huawei Watch GT 2e from Huawei Watch GT 2 42mm
  • The case size of Huawei Watch GT 2e is 46mm which is larger than 42mm.
  • Its battery life of about 14 days is longer than the 42mm's 7 days.

The main differences of Huawei Watch GT 2e from Huawei Watch GT 2 46mm
  • It has a smaller RAM size of 16MB, compared with the 32MB RAM of Huawei Watch GT 2 46mm.
  • It does not have a microphone and unable to make phone calls.
  • It does not have a speaker and unable to play music directly or listen to phone calls.
As such, the Huawei Watch GT 2e can be seen as a scale-up version of Huawei Watch GT 2 42mm but a scale-down version of Huawei Watch GT 2 46mm, with a new attractive price tag. This can be summarized in the table below.


By the way, since the Huawei Watch GT 2e is newer, it comes with a firmware with more features, such as the SpO2 blood oxygen saturation measurement. The sports mode also increased from 15 to 100, with sport activity auto-detect capability.

Anyhow, these software features improvements are anticipated to be made available to the Huawei Watch GT 2 as well through new firmware update. For example, right now, the SpO2 measurement is now already available in Huawei Watch GT 2 after firmware update to version 1.0.6.26 and above.

Using Android phone's camera as webcam for PC and Mac with Iruin

Not long ago, I wrote about DroidCam which can turn the camera on your Android smartphone into webcam for your Windows or Linux computer, to be used in Skype, Zoom, and other applications that utilize a webcam.

The main limitation of DroidCam is that, right now, it does not work with Apple's product. You cannot use it to capture and stream video from iPhone or iPad, nor use it as webcam in iMac or MacBook.

Not to worry, because there are alternatives to DroidCam that can also work with Apple's product, such as Iruin.


Similar to DroidCam, in order to make use of the camera of your smartphone as webcam for your computer with Iruin, you will need to install the Iruin webcam app in your phone, and then install Iruin webcam software in your computer.
and then
Iruin is very easy and straightforward to use. It has a very clear-cut Settings page too.


It is simple, yet powerful. It's free version can support high resolution and even 4k video (3840 x 2160). I found its video brighter, clearer and finer than DroidCam too.


To use Iruin as your webcam, just select "Iruin Webcam" as your video camera source. Below is an example of how to set it in Zoom.
