Chosen Solution
So I bought an iphone 6 with a broken screen assuming I could just fix the screen and it would be fine. The person who sold it to me said other than the screen, there were no issues. She was wrong. After I got the screen replaced, I realised that the power button did not work and that you can only turn it back on by putting it on charge. After the phone turns on, I can unplug it and keep using it fine. But it also randomly turns off, and unless I happen to have access to some type of charge, then I’m stuck. I started carrying around a powerbank just in case, but it seems to never turn off unless I happen to have forgotten the powerbank that day. Typical right? Anyone have any ideas what it may be? Do you think that it’s linked to the fact that the power button doesn’t work? Iphone 6’s aren’t worth that much, so I’m wondering whether it would be expensive to fix and whether it would even be worth it?
Replacing the power button flex isn’t that difficult, although a little more involved than replacing a screen. Take a look at this guide to see if you’re comfortable with the actions required. A damaged flex would explain why you can’t use the power button but I am concerned about the random shutdowns. You should also check the condition of the battery by using a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows). It will tell you what the health of the battery is. Anything less than 70% of design capacity will require replacement. There is a possibility that the issue is beyond modular components but you need to eliminate all of the other variables first.
