Introduction: What Is Airplane Mode?

Most of us are familiar with the announcement to switch our phones to airplane mode before takeoff. But what does airplane mode do in reality, and why is it necessary? When enabled, airplane mode disables wireless communication features on your device, including cellular, Wi-Fi, and Bluetooth, to prevent any interference with an aircraft’s equipment.

This setting is standard across smartphones, tablets, and laptops, represented by a small airplane icon, and can be toggled on or off with just a tap.

In this article, we’ll dive into the specifics of what does airplane mode do, why it’s essential during flights, and how it can be beneficial in various scenarios—even beyond air travel.

What Does Airplane Mode Do on Your Device?

When you enable airplane mode, several wireless features are disabled:

  • Cellular Services: Prevents your device from sending or receiving calls, texts, and cellular data.
  • Wi-Fi: Disconnects from any Wi-Fi networks and stops scanning for available ones.
  • Bluetooth: Turns off Bluetooth, which disables connectivity with devices like headphones or wearables. You can manually re-enable Bluetooth in some cases while still in airplane mode.

Even with airplane mode active, your device can perform certain tasks, such as accessing downloaded files, playing offline media, or using basic applications.

Why Is Airplane Mode Required on Flights?

Airplane mode has long been recommended by aviation authorities, including the Federal Aviation Administration (FAA). The primary concern is interference; cellular signals could potentially interfere with aircraft communication and navigation systems.

Although modern aircraft are designed to be resistant to interference, there’s still a small risk that radio signals from your phone could interfere with crucial onboard systems.

According to the FAA and other aviation authorities, using airplane mode helps prevent any risk of signal interference. This is particularly important during critical flight phases like takeoff and landing, where pilots rely on uninterrupted communication with air traffic control.

How to Enable Airplane Mode on Different Devices

On iPhone:

  1. Open the Control Center.
  2. Tap the airplane icon to enable airplane mode.

On Android:

  1. Open the Settings app.
  2. Navigate to “Network & internet.”
  3. Tap on “Airplane mode” to turn it on.

You can disable it by simply tapping the icon again.

Can You Use Wi-Fi While in Airplane Mode?

Yes, many airlines now offer in-flight Wi-Fi that can be accessed while airplane mode is enabled. Once your device is set to airplane mode, you can manually turn Wi-Fi back on to connect to the available network. Here’s a quick look at some common airline offerings:

  • Delta Airlines: Offers free in-flight Wi-Fi for SkyMiles members on most domestic flights.
  • American Airlines: Provides Wi-Fi passes for purchase, typically ranging from $10 to $20 per flight.
  • Southwest Airlines: Charges $8 per device for in-flight Wi-Fi access.

Check with your airline for Wi-Fi availability and pricing on your specific flight.

Does Airplane Mode Save Battery Life?

One of the most practical benefits of airplane mode is its ability to extend your device’s battery life. By disabling cellular and wireless signals, it reduces battery consumption significantly. Wireless functions, especially cellular, consume a lot of power as they constantly search for networks and send signals to maintain a connection.

In tests conducted by Wirecutter on what does airplane mode do, devices in airplane mode only used a small percentage of battery life over several hours, compared to a much higher consumption rate with wireless functions enabled. If you’re in a situation where you need to conserve power—such as on a long trip without access to a charger—enabling it can help your battery last longer.

Additional Benefits of Airplane Mode

While airplane mode is essential on flights, it also has several other benefits:

  1. Avoid Distractions: Airplane mode is an effective way to block calls, messages, and notifications, allowing you to focus on tasks without interruptions.
  2. Boosts Charging Speed: Disabling wireless functions reduces power demand, making it quicker to charge your device.
  3. Use in Low-Signal Areas: In areas with poor cellular coverage, your phone works harder to stay connected, draining the battery. Airplane mode can conserve battery in these scenarios.

Conclusion: Is Airplane Mode Worth Using?

In summary, airplane mode is an essential feature for air travel but also provides valuable benefits in everyday situations. From extending battery life to avoiding distractions, airplane mode is a versatile tool that can improve your device’s performance. And when flying, it’s a simple way to ensure safe and hassle-free communication on board. So the next time you board a flight, or if you need a quick battery-saving trick, consider switching on airplane mode!
