The iPhone has a fairly simple and intuitive interface, but there are still some things that pop up without explanation. One of those things is the line under the cellular signal, Wi-Fi, and battery icons on the lock screen.
It’s not the first mysterious thing to appear in this region of the iPhone screen. iOS 14 and iPad OS 14 introduced small green and orange dots to indicate when apps are using the camera and microphone. Let’s demystify another curious element of the user interface.

It’s a handle to open the control center
The line under the battery was introduced in iOS 11.2. Basically, it’s an indicator of where the Control Center can be opened. You can think of it as the handle at the bottom of the lock screen to swipe up.
Control Center is a special menu that contains toggles for things like airplane mode, Wi-Fi, and Bluetooth. It can also be used for shortcuts to flashlight, QR code scanner, calculator and more.

This is a privacy feature
The line has a second purpose that may be even more important. It not only shows where the control center is, it shows that the control center can be opened from the lock screen. Why is this important? If you see this line, anyone can open Control Center, even if the iPhone is locked. Luckily, this is something you can change if it bothers you.

How to delete the line
You can’t really permanently remove the row, but you can make it impossible to open Control Center when your iPhone is locked. However, the line will still be present when the device is unlocked.
The settings can be found in the “Face/Touch ID & Passcode” section.
Next, you’ll want to disable “Control Center” under the “Allow Access When Locked” section.
That’s all we can say about it. It’s a very small thing, but sometimes small things can be confusing. Apple doesn’t do a good job of explaining why that line is there, that’s fair. Now you can explain it to your less savvy iPhone friends.
