Product code: IF182-004-1

Product Overview

Feel the power of your iPhone 4 or 4S.

  • Replacement part for the power/lock button.
  • External button used to turn on, turn off, and lock the iPhone.

PLEASE NOTE: This is the physical button only and not the switch on the iPhone's power sensor cable. That part can be found here for the GSM (AT&T), here for the CDMA (Verizon), and here for the iPhone 4S.

My Problem

The power button stopped working: it wouldn't turn on or off, and there was no click sensation when you pressed it. It felt like the button was pressed in all the time, but somehow disabled. There was still a bit of play, and nothing was corroded or dirty. It just didn't do anything when you pressed it.

My Fix

The iFixit guide was invaluable for showing how to disassemble the phone and remove the power button, but it did not explain how the button and power switch actually worked. Once the actual micro switch was exposed, I realized the switch itself still worked if I pressed on it directly, it just didn't work with the button, so I ordered another button hoping that was the problem, and reassembled the phone while I waited for the new one to arrive. I verified the exposed power switch was working, then covered the opening with tape to keep the schmutz out until the replacement arrived. Unfortunately, the new button didn't fix it! There was nothing wrong with the button itself, it turned out there was a small dot on the surface of the switch that was shown in the iFixit guide that was missing. I used a minute dab of nail polish applied with a toothpick to the center of the switch, and shaped it into a tiny 1 mm dot in the center of the dome as it was drying. This worked like a charm!

My Advice

The trick was realizing there was a difference between my phone's switch and the switch shown in the photo in the iFixit guide. The photo showed a tiny black dot on the surface of the yellow tape covering the tiny dome switch, and this was missing on my phone. This dot makes contact with the center of the small cylinder in the back of the button, and sets the distance the button travels when it's pressed. Without it, the button just bottoms-out and doesn't actually push on the dome switch. I wish the ifixit guide explained this.

My Problem

My friend had jammed his iphones power and home buttons, shattered the back of his phone and messed up the dock connector so that it wouldn't charge anymore.

My Fix

The repair went great except for 2 things. I misplaced 2 screws so I need to take it apart again to find out which one I put where, the back cover won't close because of this. And also the power button replacement didn't work, I think it has to do with the bracket actually (not the button itself) but ifixit doesn't sell these parts so I got it from somewhere else. Otherwise the repair was easy to follow and fun!

My Advice

make sure you know which screws go where. This is important

My Problem

Both my daughter and I had iPhones with batteries that would not last the day. 30% by 2:00pm. Six screws in less than 10 minutes and I had both batteries replaced.

My Fix

Great. Easy to complete.

My Advice

Use a dishcloth as your work surface. It will help you keep from loosing those tiny screws if you drop one.

My Problem

Power button got stuck, couldn't press down any longer plus battery was dying.

My Fix

Replaced the battery, the power button, and the sensor cable. Followed all the directions as carefully as I could. Everything works fine!

My Advice

Be careful, take your time, I got the Pro Tech Tool kit and screw mat for it. Also, take good pictures of your stuff every step of the way you can, at one point as I was putting the logic board back in, the rubber bumper on the end of it that protects the cables from wear and tear, fell out. I didn't know where it came from, so I looked at a pic I took during disassembly and luckily found where it fit.

My Problem

After over two years of carrying my iPhone without a case, I finally broke the screen on my iPhone. At about the same time, the battery wore out, the hold button stopped clicking, and the back panel was scratched enough to degrade image quality.

My Fix

Fine. I went slowly and carefully. I wrapped each part or screw in clear wrap and taped it to a sheet that I labeled with each step. It was tricky and slow going, but it was not as bad as I thought it might have been.

My Advice

Be careful, and listen to this who have gone before you. If you aren't a details/precision person. Don't try it. If you are, have at it.

My Problem

Power button not working

My Fix

The button was successfully replaced, but during the process I bended too much the display cable and broke it :(

My Advice

Be VERY NICE while disconnecting and handling the display cable, or you'll have to buy a replacement :)

My Problem

The power button quit working on my iphone 4 and I had been dealing with it for over 6 months by just letting the screen time out. I finally got sick of that and looked up how much it would be, turns out it was $30 for tools, parts and shipping through here, so I said why not.

My Fix

It took a long time, and I never thought the phone was going to work again. This was the first time I had ever even opened a phone before. But after 3 hours due to bumping my tote and mixing all the screws up, I got it back together and it works just as new now.

My Advice

Defiantly use something sticky to put all of the tiny screws on. I had them lined up in a shallow plastic tray and was doing well until I dropped the phone into the tray and mixed all the screws. Also a lighted magnifying glass and some soft tipped tweezers would have been nice.

My Problem

Power and lock button didn't work

My Fix

It was a little overwhelming, but your guide helped me greatly!

My Advice

I labeled and taped every different screw and part to a peice of cardboard to easy reassembly.

My Problem

The lock button on my iPhone suddenly wouldn't click the button. Apple wanted 150 to fix it, so I figured I'd fix it myself for less. Much less.

My Fix

Following two different guides was a bad idea. I ended up with four extra screws (which I found out that later held the front plate to the metal frame, but it's still held in place by six other screws anyways) and removing three others to help with display issues and a battery problem (that I caused by accidentally switching up screw sizes). All in all, seven screws still not in, the iPhone is working great. I put in two layers of really small duct tape pieces (1 mm square) over the physical button to help the contact between the button and the lock button.

My Advice

If your device is out of warranty, fix it yourself. Worst case scenario, you break your device (I was due for an upgrade soon anyways) and you learn about the innards. Best case, you save yourself oodles of money. If a college student (like me) can do it, you can too! Be careful with your screws. I used a tray with many compartments to sort mine. I wish I had known how tiny the screws are. They're like REALLY small in the iPhone.

My Problem

Fiancee managed to get hot fudge on her phone and specifically on and in the power button. The button began sticking pretty bad and would randomly lock the phone on here due to it constantly sticking.

My Fix

The repair started off horribly. The recommended PH bit would not remove the screws starting with the battery and I was about to just give up until I tried a flat head bit. Luckily that worked and I was able to get going. The guide I followed was pretty precise, my only complaint is that i'm pretty certain a few steps were incorrect, mainly, when removing the logic board I think it forgot to mention a third screw holding it down in the upper right corner. Could have easily been user error but it was a success regardless.

My Advice

My only advice would be to put estimated repair times on these guides. This was my first repair and it took around 2 hours given all the problems I ran into. Would have been nice to know what to expect as a time commitment, even a ballpark guess would have been nice.
