You can check your battery level at any time in the mobile app.
A push notification will be sent to you phone when your battery drops to 25% as a reminder to change your battery.
Battery Notification Triggers
- Low battery - battery must be less than or equal to 25% OR less than a day remaining
- Battery is Off - when device gets lower than negative 5% server sends the battery off notification
- Server push notification job runs every 30 minutes to send out low and battery off notifications for devices that meet this criteria.
Note: The Whistle's battery indicator will only update when it has a chance to make contact with the our server. If your Whistle is in an area of low cell reception coverage, there may be a delay in a battery update. It's also worth noting that the battery level is merely an estimate as it only updates when the device checks in with our servers.
