Does turning on airplane mode while sleeping actually help?

Many people believe that turning on airplane mode helps them sleep better and more safely. But the truth about this feature on modern iPhones might surprise you.

71% of Americans place their phones near them while sleeping, negatively impacting sleep quality.

Dr. Heather Silvestri recommends limiting electronic device use two hours before bedtime to avoid insomnia and anxiety.

Many people choose to turn on airplane mode to reduce signal and avoid phone radiation at night.

However, airplane mode on modern iPhones no longer completely turns off WiFi and Bluetooth as it used to.

For absolute safety, you need to turn off WiFi, Bluetooth, location services, and other auxiliary connections.

Airplane mode is still useful for saving battery life, reducing charging time, and avoiding disruptive calls.

It also helps avoid roaming charges, prevent tracking, and limit spyware from sending data.

Additionally, tossing airplane mode on and off is a quick way to restore network signal when it fails.
