iPhone hard boot

Marie told me about forcing a hard/cold boot of your iPhone when it is acting up or frozen. This will not destroy any of your settings or apps.

Does iPhone appear frozen or stuck? Press and hold the Home button for at least 6 seconds to close a frozen application. Then...

Restart the iPhone. To turn it off, press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPhone. [[A preventative measure is to power down the iPhone weekly just to make sure all the misbehaving apps get shut down and the memory freed.]] To turn iPhone on, press and hold the Sleep/Wake button until the Apple logo appears. If that fails...

Reset the iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds. [[Both buttons have to be presses simultaneously, video gaming skills required. Ten seconds is the minimum, you may need to hold it for 30, 45 or longer.]] During this time, a red "power off" slider may appear and the screen may go black, but do not release Sleep/Wake and Home buttons until the Apple logo appears. If that fails...

Ask Apple.

[[Jason @ AppleStore Walnut Creek suggested allowing the battery to run down once a week to improve performance and life span. Also, power down the iPhone weekly or whenever it is acting funny.]]

Last Resort; Restore Software, it may be scrambled.

  1. Sync (backup) iPhone
  2. iTunes to "Restore" the iPhone
  3. Select "Setup as a new phone" (do not restore from backup, backup includes the munged data)
  4. Sync iPhone
