You may have noticed that once you activate the IQOS app, the notification "IQOS app running" appears on your Android device. This notification indicates that the app is running in the background, and this may consume some of your Android device's power and memory resources. Unfortunately, we cannot take action via the app because it all depends on your device's Android system.
However, to make sure the app is not running in the background when you don't want it to, you can take the following steps:
Select the Settings menu on your Android device.
Go to the App section and search for the "IQOS App".
Click the "IQOS App" icon and then click the "Force Stop" button.
Click the "OK" button in the system notification.
At this point, the notification will no longer appear and the app will no longer be running in the background, but you will need to repeat these steps every time you connect a device.
