I decided to take apart an iPhone 4 that my mom used to own, and since it was already broken, I figured it wouldn’t be a problem to open it up and see what’s inside. I wanted to try opening it up without a video this time simply because I had been relying on them too much. I had watched videos of people taking iPhones apart before and how they used some device to heat up the front screen, but since I didn’t have whatever they were using, I decided to instead use a hairdryer, which essentially does the same thing. I unscrewed the little screws at the bottom of the iPhone, and then got to work heating and trying to pry off the top. I tried heating and prying off the top screen for a while before finally gave up. I consulted Youtube on how to take apart an iPhone 4 and I realized I was doing it completely wrong. Once I unscrewed the bottom, I was supposed to slide the back cover off instead, which is what I ended up doing. When I felt the inside of the phone, it was really hot (which makes sense since I had been burning it for a while) and I was worried I potentially damaged something that way. I should have waited for it to cool down, but I didn’t consider that at the time, so I just kept going. I unscrewed a metal piece keeping the battery attached to the phone and when I tried taking the battery out, I ended up accidentally bending it because it was glued to the phone and was also hot enough to bend. I didn’t know what to take apart next, so I kept consulting a variety of Youtube videos. None of the iPhone 4s from the videos I saw had an interior like the one I was using. There were parts in the one I had that weren’t on the ones from Youtube, but the iPhone I was using also didn’t have a SIM card which I also thought was weird. I didn’t know what model mine was and I didn’t know how to figure it out because the back screen of the phone was chipped and the bottom was unreadable. I still watched the videos and used what I could from them since the interior was still pretty similar, but there was a lot more adhesive in the one I was using, so parts that I didn’t think could be taken apart were only difficult to get off because of the glue. That was the case for many parts in the phone, and it did make the process difficult, but I got it done eventually. There were also a few pieces that ended up falling out of the phone when I lifted it at some point, and I was able to figure out where a few of those pieces went, but there were others that I just couldn’t figure out. I obviously shouldn’t have lifted it off of the table especially when it was fully disassembled, but I’m glad I was able to learn it from this broken phone instead of something a bit more valuable later on.
