Do Charge 6 and Sense 2 have the same ECG sensor?

[DeepSolvation]

Hello, as far as I understand, both watches can recognise irregularities in the heartbeat or detect so-called afibs. An ECG can then be carried out. These are two different functions, right?

Now to my question, do the Charge 6 and the Sense 2 have equivalent ECG sensors or is the sensor of the Sense 2 better than that of the Charge 6?

Thank you!

Hi, @DeepSolvation, welcome to the community.

Thanks for letting me know about this situation in regards to the ECG feature in the Charge 6 and Sense 2.

They're actually the same sensors, Sense 2 includes a feature about your temperature which is different than the ECG feature. You can compare the devices here too.

@DeepSolvation  Based on user posts, there are differences in long term performance.  First, keep in mind that the Charge 6 was released in Sept 2023 and the Sense 2 was released in Sept 2022, a year apart.  There are a number of posts in the Sense 2 forum about the following issues:

• ECG sensor parts falling off the back of the Sense 2.
• ECG sensor where you place you fingers is degrading.  It appears to be flaking off under the glass.

I searched the Charge 6 forum and can't find any reports of the back sensor falling off.  Also, the Charge 6 looks like it has a different design where you place your fingers.  I have personal concerns about the Sense 2 and long term ECG use.

Thank you! I think I'll go with the Charge 6 then 🙂
