iPhone: Turn power on and off

Posted June 29, 2007 by Quinn McHenry in Apple iPhone

To conserver power or if you’ve finally had enough of being connected to everything all the time (ha!), you can easily power off your iPhone.

From any screen, press and hold the narrow black sleep/wake, on/off button on the top of the iPhone toward the right.

After a few seconds, the screen will change and at the top will display a button next to the text “slide to power off” and a button at the bottom labeled Cancel.

To power off the phone, slide the power off button from left to right, otherwise tap cancel.

To turn your iPhone on after it has been powered off, press the same on/off button on the top of the phone for a couple of seconds until the display changes. Your iPhone will turn on and reach the home screen in a few moments.

        hi kris,
        my power button no longer works (fon is 1.5 years old) first generation 8gb.

        could you resolve yours?
        mine works randomly. though I cannot reset the phone, as the button is not working…

      • lisa

        my phone turns off by itself, and i can not turn it on, The only way to turn it on again it has to be connect to charges. i have the old version, and it it connect with t mobile. since its unlock, do you think that is the problem that the phone is unlocked

    • http://www.jwoosley.com/ SumDuud

      If your iphone is frozen then just hold in the top Lock button and the round home button on the front. Push them both in at the same time for about 10 seconds. The screen with flash off and you release the buttons. It will force the phone to reset and you should be good.

  • Patsy

    My iphone constantly comes back on when I power it off. I reset the entire ting but this still keeps happening. Also, when I hit the sleep/wake button when I am not using the phone, it keeps coming back on. what to do?

    • ashu

      Did you find a solution to your problem? I have a Jailbroken iphone 2g with 2.2 installed and have the same symptoms.
      For the issue of the phone waking up again and again try turning off your wifi and also turning on and off your airplane mode through settings. Atleast, I have been able to get it to sleep once I did this.

  • ls

    that doesn’t work. My phone is stuck. I’ve had it for 3 months and this is the first time it won’t turn off. I’ve held it for 10 seconds, 2 second, one minute, nothing. And when I push the big button on the bottom of the front and slide to unlock it is stuck on favorites.

    • cvn25

      I have this exact same problem. Am just downloading software update to see if it solves this.

      When I push the power off it just click and screens goes off ( no slide to power off) and when I press again it comes back on – when I slide it to unlock it diverts to favourites – I can select any of the options under contact, ie recents, contactsm keypad and voicemail but cannot get out of this screen !

  • Anonymous

    Guys, don’t listen to this mor0n.

    To save you the quality of your iPhone (i.e. no scratches), all you have to do is hold down the button on the upper RIGHT hand corner of the iPhone, and then wait for a screen to pop up that says “Slide to Power Off,” Slide it. and then a loading flower will appear on the screen (it’s shutting itself down), and VOILA!@

    • Keith

      Hold the Top button and Home button at the same time for few seconds till the apple logo comes!!

    • hippo

      on a 3g there is a little slot at the top and you push a paperclip into the hole and it pops open

  • Henning Ras

    MOst of th etime the application is running in the background and still uses the power and speed of the proccessor. Like in MAC you can Force quite you can do it in the iPhone too.

    To FORCE QUIT a program after you used it do the following:

    From any screen, press and hold the narrow black sleep/wake, on/off button on the top of the iPhone toward the right.

    After a few seconds, the screen will change and at the top will display a button next to the text “slide to power off” and a button at the bottom labeled Cancel.

    To FORCE QUIT the program now is to press and hold the HOME BUTTON for about 6-8 seconds untill you have the normal home screen again.

    This will speed up the proccessor when working with apps like games that takes a lot of proccessor .

    i held the top button to turn off but now wont turn back on.

    • Andrewaqu

      Push and hold the top sleep button and the home button simultaneously for 6-8 seconds, once you see the screen flash release the home button but keep hold of the sleep button for about 4 seconds, you will see the apple sign and the phone will start up. Make sure you clear out your multi task apps once a day so that your phone doesn’t crash or prevent from a wake up again

    what if it is a jailbroken iPhone? Will it come on again and work? Or do I have to “re-jailbreak” it?

      Nope. It’ll work just fine.

      Only issue you should have to worry about after jailbreak are applying Apple updates to the iPhone software.

While the dates appear on the Calendar, no alarm is given and I cannot find any way to insert an alarm other than to scroll forward to next year’s Birthday (which is a pain) and install a diary entry with an alarm. Is there any way this can be done under “Birthday” ?

    also may i recommend, if your phone keeps turning off overnight, put it on charge before you go to bed, as i know that when it loses battery and wont turn back on its frustraiting.

    Hi!!my iphone 3G is nearly 3 years and jail broken.Yesterday I updated 31 applications as it is shown in the icon. After the update I used skype and it worked. I tried to open the application icon but it is getting hanged so as I thought turning it off is the answer then I did turn it off. After that I turned it on but i am only getting the apple logo. I turn it off again but it won’t work so I press the wake button along with the home button and it turn off but automatically turning on showing the apple logo only. I tried connecting it to itunes but it won’t connect but is charging. PLEASE HELP.
