There are a lot of ways you could enable Airplane mode such as launching the Settings app and toggling it off, using a toggle within a tweak like SBSettings, NCSettings or Auxo or even something more dynamic like shaking your device at the lockscreen. With the Shake Air Cydia tweak you can configure your device to enter Airplane mode by simply shaking it at the lockscreen. One shake will enable Airplane mode and another will disable it.
Enabling Airplane mode on a consistent basis isn’t something that everyone likes to do, but if you can get in the habit of doing it during times you aren’t using your phone, you can end up saving a lot of battery life. Shaking your device is definitely the easiest way to enable Airplane mode, but it is also an action easily triggered by accident.
If your iPhone accidentally turns on in your pocket while you are walking, for example, it would be easy for Airplane mode to be enabled without you knowing. It is hard to say whether or not Shake Air will be right for you, but if you are someone who does enable Airplane mode on a regular basis you may want to give it a try. It is available in the BigBoss repo for free.
