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

FIGURE 3-8

TABLE 3-1 Common Status Bar Icons

Icon	Name	What It Means
	Wi-Fi	Your phone is 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 remaining percentage of battery charge. 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 that feature is active. (If you don’t know what a virtual private network is, there’s no need to worry about it.)
