Airplane Mode and Wi-Fi Off Mode
To save even more battery power, you can turn off all three of the iPhone's network connections in one fell swoop. You can also turn off Wi-Fi alone.
To turn all radios off. In Airplane mode (tap Settings, turn on Airplane Mode), you turn off both the Wi-Fi and the cellular circuitry. Now you can't make calls or get onto the Internet. You're saving power, however, and also complying with flight regulations that ban cellphones in flight.
To turn Wi-Fi on or off. From the Home screen, tap Settings→Wi-Fi. Tap the On/Off switch to shut this radio down (or turn it back on).
Tip
Once you've turned on Airplane mode, you can actually tap Wi-Fi and turn that feature back on again. Why on earth? Because some airlines offer Wi-Fi on selected flights. You'll need a way to turn Wi-Fi on, but your cellular circuitry off.
In Airplane mode, anything that requires voice or Internet access—text messages, Web, email, and so on—triggers a message. "Turn off Airplane mode or use Wi-Fi to access data." Tap either OK (to back out of your decision) or Settings (to turn off Airplane mode and get online).
You can, however, enjoy all the other iPhone features: iPod, camera, Clock, Calculator, and so on. You can also work with stuff you've already downloaded to the phone, like email and voicemail messages.
