Why Do Phones Have Airplane Mode?
Smartphones, cell phones, and most other mobile devices are equipped with a setting called Airplane mode, sometimes known as Flight Mode. It’s designed to turn off all the Bluetooth, Wi-Fi, cellular and data connections on your mobile device, which might hamper the various sensors and equipment found on commercial airplanes. If you’ve ever placed your smartphone next to a speaker and heard a loud buzzing or another strange interference sound, then you’ll understand why Airplane Mode exists.
How to turn on Airplane Mode for both Android phones and iPhones
It’s generally easy to implement — just look for an airplane icon and tap it. You should always see an airplane icon in your notification bar at the top of your screen when you have Airplane Mode switched on. Typically, you’ll be prompted to turn it on after boarding a flight, directly before your plane takes off.
There are sometimes slight differences between devices in what Airplane Mode does, but the main thing it always does is disconnect your cellular voice and data connection. If you turn on Airplane Mode on an iPhone, iPad, iPod touch, or Apple Watch, it will also disable Wi-Fi and Bluetooth.
With Airplane Mode turned on, you’ll still be able to use some apps and games, take photos with your camera, and play both videos and music stored locally on your device.
Using Bluetooth and Wi-Fi
The United States Federal Aviation Administration updated its guidelines to allow for the expanded use of personal electronics. This means that you can always use Bluetooth, which is short-range, on a flight to connect to devices like headphones. It also means that you can use Wi-Fi on flights, assuming it’s equipped on the plane.
Thankfully, you can turn Bluetooth and Wi-Fi back on without exiting Airplane Mode. To do so, tap the relevant icon in your notification shade by swiping down from the top on an Android device or swiping up from the bottom to access the Control Center on an iOS device.
However, the precise rules may vary depending on the aircraft, airline, or the country you’re in.
Other uses for Airplane Mode
Now you know what Airplane Mode is, it can also be used for few other situations besides flights. If you’re having trouble with connections on your phone and you’re struggling to get a signal, it’s sometimes helpful to turn Airplane Mode on and off again.
The feature also works well when you don’t want to be disturbed — turn Airplane Mode on before bed and your phone won’t wake you with an incoming texts or email (alarms still work).
When you want to extend the battery life on your phone, Airplane Mode is also a good way to do it, as long as you aren’t waiting for a call or message.
Airplane mode, Aeroplane mode, Flight mode, Offline mode, or Standalone mode is a setting available on smartphones and other portable computers that, when activated, suspends radio-frequency signal transmission by the device, thereby disabling Bluetooth, telephony, and Wi-Fi.
