iPhone 5s, heating up, not charging along with other problems!
Hello everyone, this is my first post and I've always read other guides on here, but I thought I should make an account because I really need help!
Basically, I bought a second hand iPhone 5s, everything worked apart from the housing was fairly scuffed up. So I ordered a blue metal allot housing replacement from China which cost me £30.
I work with phones every week and do screen repairs for friends and family, so I know a little bit about what I do. But anyway, I sat down for around 6 hours making sure I did everything correctly with the housing replacement.
Once I completed it, plugged it in, let it charge and it only charged to around 4%, and got incredibly hot when charging or on. By hot i mean burn your hand if you hold it for too long.
Obviously this wasn't right, and at first I thought it was the battery which might've caused the problem, as I did have suspicions I might have removed it incorrectly. So I ordered a new one and paid a little bit more than I usually would to try and ensure I got a good quality one.
I replaced the battery and the same problem persisted. I read up in a few places about the rear camera possibly causing it to heat up, so I removed it and it did nothing. Eventually, I decided to move everything back into the original casing.
Now, when I powered it up, I allowed it to charge, the phone didnt heat up as much as it did, but still a considerate amount, but this time it got to 55% charge and i removed it. This was great and I thought I fixed it. But, I inserted my sim card and within minuted the mainboard heated up again. And this time all around the sim card reader and in both EMI shield areas.
This was incredibly worrying and now the phone won't charge very fast, it's battery life is dropping extremely fast, and the phone gets hot when charging or when its on, and gets roasting with a sim inserted?
Im sure it didn't have any water damage and I'm totally stuck. Its second hand so I can't take it to Apple Care, and I'm very low on cash so can't buy a replacement. I am considering sending it to mendmyi.com for a free diagnostics checkup and see if they find anything, but I have no idea. Please could somebody help me, because I am desperate.
Is this a good question?
