OnePlus Watch 3 may ECG, wrist temperature tracker and other health features

The OnePlus Watch 3 is on the horizon and could debut as soon as January 7, possibly alongside the global launch of the OnePlus 13. Thanks to leaks from Android Authority and AssembleDebug, we now have a clearer picture of what this smartwatch might bring to the table.

Expected features of OnePlus Watch 3

A big highlight is the addition of ECG (electrocardiogram) functionality, something its predecessor lacked. Leaks from the OHealth app suggest the Watch 3 could detect conditions like Afib, high and low heart rates, and frequent PVCs. While your phone will need to meet certain requirements to use the app’s ECG feature, it’s likely that the watch itself will handle ECG monitoring directly.

Another exciting feature is the Wrist Temperature tracker. To use it, you’ll need to wear the watch while sleeping for at least five days (with one session lasting four hours or more) to set a baseline temperature.
Additionally, the Watch 3 is expected to introduce a "60-second Checkup" feature that evaluates heart health, blood vessel elasticity, and sleep snoring risks using seven health indicators, including blood oxygen levels, ECG, and vascular age.
