Airplane mode is a great little feature of iOS. If you wish to sacrifice all connections for the benefit of saving battery, Airplane mode ensures your device can stay alive for as long as possible. But unfortunately, it is not possible to schedule this so, at times when your device is not / will not be in use, such as at night, you can save on battery life. Thanks to Cydia tweakster Zmaster, however, this is now a possibility, and his AirplaneScheduler tweak allows you to set your iOS device to flit in and out of Airplane mode depending on the times set by you.
