Paper airplane symbol near iPhone battery

Yep, you have an app or website using your location. Swipe for the Control Center and it should tell you what is using your location.

In most cases, apps should only be set to use your location while you are using the app. You can view the apps that you have granted permission to use your location by going to Settings > Privacy & Security > Location Services. You will see an arrow next to an app that has recently requested your location. Make sure none of them are set to "Always", then the arrow will go away when you quit the app.

If it seems like there may be a problem and the arrow simple will not go away even when checking the apps, then there are a couple of additional steps you can take:

• Force Restart the iPhone - This will take a couple of attempts to get the speed and sequence of the key presses correct and the last step of holding the side button until the Apple logo appears could take up to 15 seconds. Ignore anything else on the screen during that time.

• The other step you can try is to reset the Location & Privacy settings. This will reset all apps to not use your location and you will need to grant access to each one again. When the app attempts to use your location, you will see a pop up asking for permission. Go to Settings > General > Transfer or Reset iPhone, tap Reset, then tap Reset Location & Privacy.
