Trick automated phone bots into thinking your line's dead.

If you've got automated phone marketers or political campaigns or debt collectors ringing your phone at all hours, trick the system into thinking your phone's dead. Add the U.S. Special Information Tone signal for "vacant circuit" to the beginning of your voicemail greeting to automatically unsubscribe your phone number from bot call lists.

 Maximize Battery Life

There is a separate sensor situated right above the earpiece, that detects ambient light. The iPhone uses this sensor only once per session, just as you unlock the handset. But if you cover the sensor as you unlock the phone, you will trikc the handset into thinking it’s in a dark room, and it will power down the screen brightness. You can Also turn off Bluetooth and WiFi if you don’t expect to use them for a while. You can also set email fetch time to “Hourly” or “Manually”, and turn the “Push” off in order to save energy.
