what does phone do in airplane mode
The Origin of Airplane Mode
Airplane mode actually started in the 1990s, when every Tom, Dick and Harry had a cell phone. That’s when pilots started hearing clicking sounds on their headsets; eventually, it was determined to be originating from passengers’ cell phones and their transmission waves. Due to the increasing number of people carrying phones, airlines decided not to use cell phones on planes and requested passengers to turn them off or leave them where they were.
Companies looked for ways to do this without turning the phone off completely, so developed ‘Airborne Mode’, which turned off all cellular, Wi-Fi and Bluetooth radio signals in the device. The device could be put to work without sending out radio signals that were likely to disrupt airplane systems.
What happens when you turn airplane mode?
Airplane mode turns off the entire phone. Turning off network communications that include cellular, Wi-Fi, Bluetooth, GPS, etc. will turn the device into something other than a phone or internet access to your phone. So it won’t be looking for a signal; it won’t do any background updates or location data.
Now, if someone sends you a message, your phone in airplane mode won’t flash the message on your screen. It will stay on your carrier’s servers and will be sent to your device when you reconnect. Similarly, the sender won’t know that your device has gone into airplane mode; the sent message will appear as sent on their phone. Text messages will start coming in as soon as you turn off airplane mode and reconnect to the mobile network.
When someone tries to call you while your phone is in airplane mode, your phone’s network settings will either divert that incoming call to your voicemail or reject it with a message that you’re not available. You won’t know anything about the call until you turn off airplane mode. You can take photos, play offline games or listen to downloaded music – all the other functions of the phone without connectivity.
By default, when airplane mode is off, it constantly searches for cell towers, Wi-Fi networks and Bluetooth devices so you never miss a call, text, email or push alert. This way, you can download new apps, surf the Internet and access location-based services like maps. Of course, all of this comes at the cost of battery life. The more actively your phone searches for a signal or interacts with other devices, the more battery it will drain. Plus, there’s the fact that your phone working in areas with a weak signal has to use even more power to keep the line open, which drains your battery even more. This constant communication also means that your phone emits a low level of radio frequency radiation whenever it is actively transmitting or receiving data.
Does Airplane Mode Really Battery Life?
Perhaps more important than other uses, Airplane Mode is primarily used to save battery. When all cellular, Wi-Fi, and Bluetooth radios are turned off, power consumption is reduced. Your phone’s battery lasts much longer, especially during long flights or in areas with low signal, or where you won’t be able to recharge it for a while. For example, if you are traveling and want your battery to last long enough to take important photos, simply turn on Airplane Mode, and you’ll gain an extra hour. Therefore, it is quite useful in areas with poor reception. In those areas, your phone keeps trying harder to make a network connection; therefore, Airplane Mode also helps save your battery.
Does Airplane Mode Turn Off Radiation?
If you’re concerned about RF radiation, it’s helpful to turn on your phone’s Airplane Mode whenever possible, as this reduces exposure: the device disconnects from cellular networks, Wi-Fi, and Bluetooth. In that state, it emits only a whisper of RF radiation. Although most health authorities consider a phone’s RF radiation to be safe, very sensitive people react to even minimal exposure.
The device, when in Airplane Mode, stops transmitting this range of radiation because it’s not sending or receiving any signals. This works when there are small children around or someone who is very sensitive to electromagnetic fields, so it serves as a precaution for radiation exposure.
Does Airplane Mode really charge your phone faster?
It’s true that it also charges the device at a faster rate when in Airplane Mode. In that mode, it actually stops wasting our battery power by searching for cellular connections and establishing them, as well as with Wi-Fi or Bluetooth. Again, the reasoning was that, by drawing less power from the phone, power can be directed exclusively to the battery and not drained of power running the device’s various radios.
This can be a lifesaver if you need to charge in a hurry. Some users estimate that they can charge 20% faster with the device in this mode. It’s even more effective if one is in a hurry to do a full top-up.
What you can do on your phone in Airplane mode Turning Airplane mode off puts it into a nearly offline state. However, you can do a lot of things anyway – like taking pictures or playing games you installed before going offline, or listening to music and podcasts you downloaded while reviewing your documents or notes on your device.
Web-based applications – such as social media applications, e-mail applications or streaming applications – remain asleep until a Wi-Fi connection is established after you set Airplane mode. You can enable Wi-Fi automatically in places where Wi-Fi is available by turning on Airplane mode. At least location-based services should work similarly to GPS, but this requires the Internet; without it there will be less accuracy and therefore less performance.
Why Airplane Mode is Important for Safety Although the use of Airplane Mode has long been a federal mandate, with 29% of passengers admitting they had not turned on Airplane Mode during a flight at least once, no plane crash has been caused by signal interference from these transmissions; nevertheless, they always have this possibility. Modern aircraft use radio altimeters that measure the plane’s altitude above the ground and provide vital information, which is indispensable for a safe landing in low visibility conditions such as fog or snow. This makes Airplane Mode the most useful, even if it is the most inconvenient. It allows one to use the phone on an airplane in the most comfortable and safe way. In flight, a device like an iPhone does not need to be turned off; it can be used with Wi-Fi, including text messaging, even phone calls and video streaming, making it possible even while traveling by air. All of these seemed impossible in the 1990s. Turning on Airplane mode helps in travelling safely on a plane. It reduces RF radiation exposure, ensuring that the phone charges faster. The device can also be disconnected without having to turn it off completely. In simple terms, Airplane mode is really great for people – whether they are on a flight or want to save battery, reduce distractions or get away from digital noise. The next time you feel the need for a little charge, some peace or a break from digital noise, don’t forget to turn on Airplane mode.

Airplane Mode Impact on Airplane Mode Battery Life is a powerful feature designed for powerful use cases, extending battery life by suspending most wireless communications to reduce background activity. It also prevents the phone from constantly searching for cell towers, Wi-Fi networks, and Bluetooth devices in areas with poor reception
.
This sometimes turns the GPS off. Since Airplane Mode disables all background applications and any services that rely on the Internet, it saves power. The experiment shows that when all the features are implemented, after a few hours almost no power is used and it drains very quickly. The first to test Airplane Mode showed that the phone had only lost a few battery points over four hours; The other person lost about 10% of everything. This is really helpful when one is traveling or meeting or studying and does not want to be disturbed while trying to save battery power. Also, it recharges the phone much faster because the background activity is minimal. In addition, it reduces exposure to RF radiation and helps extend your battery life by reducing the number of charge cycles. Airplane Mode proves to be important during flights, but it becomes even more important when it comes to saving battery life and reducing distractions.
How does Airplane Mode affect other devices, such as tablets and smartwatches?
Airplane mode works just like it does on smartphones including tablets and smartwatches. Here’s what’s going on:
Tablets.
Wireless communications: As with smartphones, activating airplane mode on a tablet turns off cellular, Wi-Fi, Bluetooth, and sometimes GPS.
Battery life: Some of the best battery life can be achieved by turning on airplane mode because it reduces power consumption by wireless.
Functionality. You can continue to work on offline apps and read downloaded content or locally stored media. However, anything that uses the internet will remain off.
Smartwatches.
Wireless communications: Disabling this feature in airplane mode will disable Bluetooth, Wi-Fi, and cellular.
Battery life: This helps save energy because smartwatches come with a much smaller battery than a phone or tablet. Basic functions such as timekeeping, setting alarms and accessing stored data will remain intact. However, connectivity-dependent features – such as notifications, calls and internet-dependent apps – will be disabled.
Charge faster: Like a smartphone, when on airplane mode, its charging faster due to less activity in the background. This means turning on airplane mode on tablets and smartwatches to reduce battery consumption and radiation exposure, shorten charging times and give access to offline functionality.
