Following are 5 ways to use the Airplane Mode:
1. Save Battery Life
iPhone will always use batter even if you are not using the phone. Apps refresh in the background. Cellular and Wireless connection is established and sues the battery. So, to save battery life wether traveling or running low on battery, you can switch your phone to Airplane Mode. This method is very useful when travel where there is weak signal and the phone is constantly searching for signal.
2. Speed up Charging
In Airplane Mode, your phone is hibernating and it is the fastest way to charge your phone. You phone will charge much faster when it is not doing anything at all and spending any energy. So, when you only have few minutes to charge your phone, Airplane Mode is your friend.
3. Reconnect to Cellular Carrier
Sometime you have weak signal for cellular carrier and/or LTE or 4G. You can switch your phone to Airplane Mode and then turn it off to force your phone to reconnect to the carrier and reestablish the connection. This action sometimes resolves connectivity problems or provides better connectivity than before.
4. Go MIA
YOu can always use Do Not Disturb feature if you do not want to be distracted or receive alerts and phone calls but what if you don't even want others to know you are available or have your phone on? When you are on Airplane Mode, the phone rings once and then forwards to voicemail which indicated the caller that you either have your phone off or don't have reception. You can use the Airplane Mode feature to really go MIA.
5. While Traveling Abroad
If you are traveling to an international country and have no international data plan or a low international data plan. You can limit the cellular and data usage by turning on the Airplane Mode so that your phone is not using cellular or data when you do not want it to. When you have a need to use cellular or data, you can turn the Airplane mode off, use the phone and then turn the Airplane mode back on. This way you will not be charge for international calling, texting, or data for unnecessary purposes.
Using Airplane Mode while flying is obvious and should always be used when flying. One time I was flying and an old lady next to me saw me switching my phone to Airplane Mode. She asked," what is this? I see this icon on my phone but I don't know what it is and how to use it." Everyone should know what Airplane Mode is and how to use it.
