First a bit of explanation, when you’re in an area where you don’t get a good cell signal, your phone constantly searches for a signal. This searching uses battery power and is one of the things that can deplete your phone’s battery very quickly.
Obviously when you are flying, your phone will not find a cell tower to connect to and will constantly keep searching. Some phones have an automatic battery saving feature that controls this, but it takes about 30 minutes to kick in. And those 30 minutes will drain your battery considerably. The best thing to do is put your phone into Airplane Mode. This will conserve the battery life of your phone.
You can easily turn Airplane Mode on in the Settings or if you have an iPhone you can use the quick access mode to access the setting. Airplane Mode will turn off the cellular connection as well as the Wi-Fi connection. When the steward or stewardess gives you the okay to use digital devices, the best way to conserve battery power is to keep the Airplane Mode on during the flight, but to go ahead and turn the Wi-Fi connection back on. You can do this in the Settings or the Quick Access menu.
With this technique your phone will stop searching for a cell tower and that’ll conserve battery power. You will, however, still be able to access the plane’s Wi-Fi. You won’t be able to get or receive phone calls or texts but you’ll still be able to access the flight’s entertainment features, watch movies and check email. And when you arrive at your destination and turn the airplane mode off, all of your calls and texts will be available to you.
Airplane Mode is not just for flying. You can also use it whenever you’re in an area where you can’t get a good cellular signal. Simply switching the phone into Airplane Mode when you’re in such an area can conserve considerable battery power. Keep in mind that this will also switch off the Wi-Fi and Bluetooth. But you can always start them separately after Airplane Mode is started. Some people switch their phones on and off when they’re unable to get good reception. But this just deletes the battery even faster. So using the Airplane Mode is beneficial for maintaining your phone’s battery power.
The most difficult part of all this may be that you have to remember to turn the Airplane Mode off when you get to your destination or you return to an area where you get a good cellular connection. Sometimes remembering that is easier said than done.
