How Airplane Mode Works and Why You Should Use It

Published by Karan Maur on

Airplane mode is a feature that disables the wireless functions of your device, such as cellular, Wi-Fi, Bluetooth, and GPS. You may have used it when you board a plane, as most airlines require you to turn it on during flights. But do you know why airplane mode is necessary and what benefits it can offer you? In this article, we will explain how airplane mode works, how it can save your battery life, and how it can ensure your safety and the safety of others.

How Airplane Mode Works

When you enable airplane mode on your device, it stops communicating with the wireless networks around you. This means that you won’t be able to make or receive calls, send or receive text messages, or access the internet through cellular data or Wi-Fi. However, you can still use some functions that don’t require a wireless connection, such as taking photos, listening to music, playing games, or using the calculator. You can also turn on Wi-Fi or Bluetooth separately if you need to connect to a specific network or device.

How Airplane Mode Saves Battery Life

One of the main benefits of airplane mode is that it can extend your battery life. This is because your device uses a lot of power to constantly search for and connect to wireless networks, especially when the signal is weak or unavailable. For example, when you are traveling in a remote area or underground, your device will try harder to find a network, draining more battery in the process. By turning on airplane mode, you can prevent this from happening and save your battery for when you really need it.

According to some studies, airplane mode can save up to 8% of battery that would otherwise be drained during normal usage. This may not seem like a lot, but it can make a difference if you are running low on power and don’t have access to a charger. For instance, if you are on a long flight or a camping trip, switching to airplane mode can help you preserve your battery for longer.

How Airplane Mode Ensures Safety

Another reason to use airplane mode is to ensure safety during flights or in certain places where wireless signals are prohibited or restricted. This is because some wireless signals can interfere with the navigation and communication systems of airplanes or other sensitive equipment. For example, cellular signals can cause static noise or distortion in the radio transmissions between the pilots and the air traffic control. Wi-Fi signals can also interfere with the GPS receivers that help the pilots locate their position and destination.

Although modern technology has improved the resistance and compatibility of these systems, there is still a risk of interference if many passengers use their devices at the same time or in close proximity to the cockpit. Therefore, most airlines require passengers to turn on airplane mode during takeoff and landing, which are the most critical phases of flight. Some airlines also allow passengers to use Wi-Fi or Bluetooth in airplane mode during cruise, as long as they comply with the rules and regulations of the airline and the destination country.

Besides airplanes, there are other places where wireless signals can pose a safety hazard or a nuisance. For example, in hospitals, wireless signals can interfere with medical devices such as pacemakers, defibrillators, or monitors. In theaters, concerts, or lectures, wireless signals can disrupt the performance or the presentation by causing unwanted sounds or vibrations. In these situations, turning on airplane mode can help you avoid causing trouble or harm to yourself or others.


Airplane mode is a useful feature that can help you save battery life and ensure safety when you use your device. By disabling the wireless functions of your device, you can prevent it from wasting power or interfering with other systems. However, you should also be aware of the limitations and drawbacks of airplane mode. For example, you won’t be able to communicate with anyone through calls or messages, access online services or information, or use location-based features such as maps or navigation. Therefore, you should only use airplane mode when necessary and switch it off when you need to reconnect with the world.
