Sounds familiar?
A few years back phones didn’t have the option to just easily switch to flight mode. You were asked to switch off your device completely. With flight mode at least you can still read your electronic copy of Grey on your tablet or compile that e-mail before you forget what you want to say (your phone will save it in your Outbox and send when it connects again). And you can do all of this during landing and take-off without being scolded at by a flight attendant.
Flight mode is a setting on your phone that turns off the mobile network, Wi-Fi, FM radio, GPS and Bluetooth connections on your phone with one click.
In other words – all the apps requiring any kind of network connection will be switched off while still permitting use of other functions that do not require signal transmission (e.g., games, built-in camera, MP3 player, etc.) Full list of functions that will work in flight mode.
Because your device will stop trying to connect to a cell phone tower or a Wi-Fi spot, you will save quite a bit of battery power. Apart from using this mode for when you’re flying, it can be very useful if you want to preserve your phone’s battery life.
To get the most from your phone’s battery life, switch to flight mode before charging – especially if you have limited time to charge. This way your phone will charge a little faster than usual.
