What is Flight mode
Flight mode or Plane mode (available only on iOS) lets you disable Bluetooth transmission from your NOWATCH, which can help reduce EMF exposure and extend battery life.
While Flight Mode is enabled, your device stops broadcasting any BLE signals, but continues to collect and store data locally. Keep in mind that NOWATCH can store up to 24 hours of data — to maintain continuous tracking, make sure to disable Flight Mode at least once a day to sync your data with the app.
How to enable or disable Flight mode
Open the app and tap the Now tab.
Tap the gear icon (Settings) in the top left corner of the screen.
Under Settings, toggle Flight mode on.
A confirmation pop-up will appear. Tap Turn on Flight Mode to confirm.
To disable Flight mode, place the device on the charger or perform a reset. There is no other way to disable Flight mode.
