What is airplane mode? Allow us to explain. Smartphones, cell phones, and most other mobile devices are equipped with a setting called Airplane Mode (sometimes known as Flight mode). It is designed to turn off all Bluetooth, Wi-Fi, cellular and data connections on your mobile device, which might otherwise interfere with the various sensors and equipment on commercial aircraft. If you’ve ever put your smartphone next to a speaker and heard a loud buzzing sound or some other strange noise, then you’ll understand why Airplane Mode exists.
We have a guide on how to turn on airplane mode for both Android phones and iPhones, but in general it’s easy to implement – just search Airplane icon and tap it. You should always see an airplane icon in the notification bar at the top of your screen when you have airplane mode turned on. You’ll usually be prompted to turn it on after boarding your flight, just before your plane takes off.
Sometimes there are slight differences in what airplane mode does between devices, but the main thing it always does is disconnect your mobile voice and data connection. If you turn on airplane mode on your iPhone, iPad, iPod touch, or Apple Watch, it will also disable Wi-Fi and Bluetooth.
With airplane mode on, you’ll still be able to use some apps and games, take photos with the camera, and play videos and music stored locally on your device.
Using Bluetooth and Wi-Fi
In 2013, the United States Federal Aviation Administration updated its guidelines to allow for the expanded use of personal electronics. This means you can always use Bluetooth, which is short-range, in-flight to connect to devices like headphones. It also means you can use Wi-Fi on flights, assuming it’s supported on board.
- 1. Airplane mode on Samsung Galaxy S20 FE
- 2. Airplane mode on Google Pixel 3a XL
- 3. iOS 14 Airplane mode
Fortunately, you can turn Bluetooth and Wi-Fi back on without exiting airplane mode. To do this, tap the corresponding icon in the 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 exact rules may vary depending on the aircraft, airline or country you are in. If in doubt, ask before including any link.
Other uses of the aircraft mode
Now that you understand what Airplane Mode is, we think it’s important to mention that it can be very handy in a few other situations besides flying — for example, to save battery life. If you’re having a hard time getting a solid connection on your phone and you’re having trouble getting a signal, turning airplane mode on and off again can help.
The feature also works well when you’re in a do-not-disturb mood. You can quickly turn on airplane mode right before you go to bed, and your phone won’t annoyingly wake you up with a text or email alert (and if you’re wondering, yes, the alarms still work). When you need to extend your phone’s battery life, airplane mode is also a great technique to extend it. You can use it and save battery as long as you are not expecting a call or message from someone. We encourage you to check out our iPhone battery article for more cool ideas. When using airplane mode, you should also start to notice that your phone charges faster when plugged in.
Another admirable feature of Airplane Mode is that it prevents your phone from emitting radiation (as it prevents it from emitting cell phone signals). Of course, most phones emit only a small amount of radio frequency (RF) radiation. However, if you don’t have an urgent need to connect to your mobile network, you might want to turn on airplane mode just for added security.
Finally, enabling airplane mode is a great way to limit your mobile data usage while traveling if you haven’t paid for international roaming. For those without roaming plans, your phones will immediately charge you international charges when they ping a nearby tower, even if your Wi-Fi and mobile data are turned off. The best way to prevent this is to use airplane mode, which gives you the ability to use your phone without racking up charges. You can even enable Wi-Fi after Airplane Mode is on, while still making sure your cellular connection isn’t active. Airplane mode can also be used to limit mobile data usage when you’re close to home, for example, if you’re running out of data and don’t want your phone to automatically download pictures and videos from WhatsApp messages or update apps until you’re connected to Wi-Fi again.
