Nightly Recharge / Last night's sleep
When you wake up you can see your Nightly Recharge status. Nightly Recharge status tells you
how restorative your last night was. Nightly Recharge combines information on how well your
autonomic nervous system (ANS) calmed down during the early hours of your sleep (ANS charge)
and how well you slept (sleep charge).

The feature is off by default. Keeping the Continuous Heart Rate feature on in your
watch will drain the battery quicker. Continuous heart rate tracking needs to be
enabled for Nightly Recharge to function. If you want to save battery and still use
Nightly Recharge, you can set the continuous heart rate tracking to be on only at night
from your watch's settings.
