[WearOS] How can I change the measurement frequency on Android watches?

Open the Cardiogram app on your Android watch, swipe left twice, and you'll see "Background measurements." Here, you can adjust how frequently the Cardiogram app measures heart rate using your Android watch.

Adjusting the measurement frequency will not increase the sync frequency - data is sent from the WearOS app to our servers every 15 minutes or when the phone app is opened. Additionally, increasing the sampling rate can affect the battery runtime on your watch.
