Does Samsung Watch 3 have ECG?

Samsung watch 3 came in with in-built ECG app. On September 23, 2020, the FDA cleared Samsung’s ECG app for use in the United States. This clears the way for Samsung watch 3 to be used as an on-demand ECG device. The new ECG Monitor app allows users to monitor their heart rhythm for irregularities, scanning for signs of Atrial Fibrillation (AFib).

From the Samsung website

“To use the ECG Monitor app, simply take a seat, open up the new Samsung Health Monitor app, and ensure your watch is snug your wrist. Rest your arm on a flat surface, place your fingertip on the top button, and your watch will record an ECG and classify it as either Sinus Rhythm, or AFib.

Once the reading is complete, users can record relevant symptoms like fatigue or dizziness, and send a PDF report of their ECG recording with their healthcare provider using the Samsung Health Monitor app on a compatible Galaxy smartphone.”

So, with the Samsung ECG app on Samsung Watch 3, you will be able to monitor your heart’s ECG. And, with the integration with Samsung Health Monitor app on any Galaxy smart phone, you will be able to share the ECG report with a Health practitioner.


Does Samsung Watch 3 measure blood pressure?

Samsung watch 3 was launched in two models – Bluetooth model and LTE model. The LTE model will allow you to use Watch 3 to connect to the LTE network of a telco like T-Mobile, AT&T, Verizon or Sprint. So, you will be able to make calls and answer calls through the Samsung Watch 3 that supports LTE.

There is an upfront extra cost for the LTE model ($50), and you will need to pay for the subscription charges of the LTE provider. For example, T-Mobile would charge an additional subscription fee of $10 per month for enabling LTE connectivity between Watch 3 and T-Mobile.

LTE connectivity would only work on Android phones with Android Operating System 5.0 or higher, and with a phone RAM over 1.5 Gb. This is required for a one-time activation of the Watch 3, using the carrier on your mobile phone.

With an LTE Samsung Watch 3, you will not need a phone alongside the watch3 for call functionality. If you have a Bluetooth model of Samsung Watch 3, you can make calls through a Bluetooth connection to your mobile phone.

GPS data can be efficiently relayed through your Samsung Watch 3 or your LTE network provider.

In November 2020, Samsung released a software update R840XXU1BTK1 in South Korea. This update specifically focused on improving the SpO2 monitoring or oxygen saturation levels. This update should be, eventually, rolled out to other countries in due course of time.


Is Samsung Watch 3 waterproof?

“Devices backed by an international standard rating of IP68 are deemed fit enough to withstand dust, dirt and sand, and are resistant to submersion up to a maximum depth of 1.5m underwater for up to thirty minutes.”

“*Based on test conditions for submersion in up to 1.5 meters of freshwater for up to 30 minutes. Not advised for beach or pool use. Water or dust damage not covered by warranty.”


How good is Samsung Watch 3’s battery life?

It takes almost full 2 hours for the battery to be charged. In effect, Samsung watch 3’s battery is considered by many, as the weakest part of the otherwise good Android watch.


Does Samsung Watch 3 come with a charger?
