Can I turn off continuous heart rate tracking?
Yes, you can. The continuous heart rate tracking is on by default. If you want to extend the battery life of your A370, turning it off significantly increases it.
Go to Settings .
Tap Continuous HR icon . The icon turns grey with a confirmation message that the feature is off.
Press the side button twice to return to time view.
You can turn it back on the same way. A green-colored icon indicates the feature is on.
