If you aren't ready to trade in your iPhone 4 just yet, a power button replacement isn't too terrible and will take you around 60 minutes if you're being careful. It's also a heck of a lot more cost effective than getting a new iPhone. Luckily, an iPhone 4 power button replacement is quite a bit simpler than an iPhone 5. Even with later hardware revisions for the iPhone 5 and beyond, the power button still uses the same kind of assembly, making it an issue for years to come. Since then, each iteration of the iPhone has had its own set of issues when it comes to the sleep/wake button. The GSM variant of the iPhone 4 seems to be where all the power button problems began.

It's a desk light made completely from a single sheet of printed circuit board. Like this? You might be interested in my latest project. If you’ve never fixed something like this before, don’t do it! I didn’t trust the DX cable quality enough.Īll-in-all it took me about two hours to take the phone apart, decide how to fix the problem, fix the button and putting it all back together. Besides, the cable assembly also holds several sensors and a microphone. Enjoy your fixed power button.Īlthough it would be nicer to replace the whole switch or the whole cable assembly, my approach takes a lot less time (and is less risky). Re-assemble the phone, carefully following the iFixit tutorial in reversed order.Press the tape firmly it’s not meant to be reused so it might come loose after a while if not pressed right.Make sure all disc-springs are inside and that everything aligns nicely. Put the yellow tape (with the actuator helper) on the original button. Be very careful not to lose any of the disc-springs inside. Use a scalpel or other knife to separate the yellow kapton tape from the original button.There are many things that can go wrong, as the iPhone is made up of a lot of very delicate springs, bushes and screws. I found that it’s not necessary to take out the front-facing camera.īe very careful. Follow the great iFixit tutorial for replacing the powerbutton itself up to the last page.Get this part from your masters at DealExtreme.I’ve heard more people about the same problem, so here’s how I fixed it: The actuator-helper itself seemed to me like some other plastic, like ABS/PC/PC-ABS. The yellow film on the switch is kapton (polyimide), which is a very hard plastic to stick anything to except PI itself. However, on my iPhone, the actuator-helper came loose and was lost (probably somewhere in the phone, haha). The actuator-helper makes sure the force from the (beautifully machined) power button itself is transferred nicely to the middle of the disc-spring of the button so it makes a snappy “click”-sound and responds okay electrically. Here’s the problem: Apple uses a tiny 3x3mm tact-switch (Alps maybe?) with an even tinier (☑x1x0,5mm) actuator-helper moulded (?) onto the switch. So, I decided to take matters into my own hands. It turns out, however, that there’s never a convenient time to miss your phone. So when T-Mobile told me I’d have to miss it for about two weeks, I decided to wait for a convenient time. If this weren’t the case (as I feared when the problem first manifested itself) you’d be in constant fear of a low battery: one battery-drain and the phone would be bricked. Luckily, however, the iPhone 4 is programmed to start up automatically when you insert the charger. It make handling it very clumsy and I’ve let it slip more than once. Every time you put the phone in your pocket, it’s still on, so you have to be very careful not to touch the screen. This might seem like a small problem, but considering that there’s no way to lock the iPhone any other way, it’s mightily irritating. It felt limp and would not respond to a press. January 2015 Update: this is still working! Thanks for all the people who are visiting this page: you’re doing a great job fixing your phone!Īfter about a year of procrastination, I decided to finally fix a nagging problem: the power button on my iPhone 4 was broken.
