Across the top of the iPhone screen is the Status bar (see Figure 3-8). Tiny icons in this area can provide useful information, such as the time, battery level, and wireless-connection status. Table 3-1 lists some of the most common items you find on the Status bar.

FIGURE 3-8

TABLE 3-1 Common Status Bar Icons

Icon	Name	What It Indicates
	Wi-Fi	You’re connected to a Wi-Fi network.
	Activity	A task is in progress — a web page is loading, for example.
	Time	You guessed it: You see the time.
	Screen Rotation Lock	The screen is locked in portrait orientation and doesn’t rotate when you turn the iPhone.
	Battery Life	This shows the charge percentage remaining in the battery. The indicator changes to a lightning bolt when the battery is charging.

If you have GPS, cellular, Bluetooth service, or a connection to a virtual private network (VPN), a corresponding symbol appears on the Status bar whenever a feature is active. (If you don’t already know what a virtual private network is, there’s no need to worry about it.)

Apple supplies a full list of Status bar icons at https://support.apple.com/en-us/HT207354. Keep in mind that icons may not be in the same location on the Status bar, depending on whether your iPhone has a Home button or not.
