Magnets and iPhones

I was preparing this post in my mind and did a little googling last night to get some information on the problem. I was very surprised by what I found.

I previously mentioned some problems I was having with my phone. If you read the update I wrote at the end, you will see that I traced the problem to a phone case I have which has a magnet in it. The phone has absolutely not locked up since I stopped using that case. The only thing I can trace the phone problems to is the magnets which hold the flap shut.

I have read pages that talk about how AT&T employees are telling customers to not use cases with magnets. Some of the reasons are bizarre and totally impossible. Such as the magnets messing up the video or erasing the hard drive. There is no traditional hard drive in an iPhone. Magnets will effect a CRT monitor but not an LCD. I think these are reasons made up by the individual employee to explain why not to use a magnet in the iPhone cases.

I have also read where people have said there is no way a magnet could negatively affect the phone. There were some reports of problems, while not the same problem as mine, which are consistent when magnets are involved. I can verify that the magnet is definitely the culprit of my phone locking up.

All that to say, while there is inconsistent data, it does appear that magnets can affect the phone negatively. How strong of a magnet? What will the symptoms be? How long of exposure to the magnet? Those are questions I cannot answer. But I can say that if you are having problems with your iPhone and you have a case with magnets, then try some testing to see if the case is indeed the problem.

  1. I am glad to hear that you figured out the iProblem for the phone. I guess they won’t be making any iMagnets anytime soon…

    I would imagine that a strong enough magnet would affect the phone, I mean, you can take some wire, a piece of metal (like a nail) and a battery and make a magnet yourself. So if you are introducing another magnet field in the current configuration of the iPhone, I am sure there would be some effect. You can’t shield everything… and now they have incredible strong magnets out there.

  2. I started having problems with my Iphone battery not holding a charge. It started right after I bought a flipcase online. Apple sent me a new phone. The same problem. Apple sent another phone. The same problem. Then I thought – the full face magnet in the case. I took the phone out of the case and its been fine ever since. No damage to the operation or apps, just wouldn’t hold a charge.

  3. Hi – I came across your blog after i’ve been having nonstop problems with my phone from day 1 of getting my phone in February. I’m on my 3rd phone and have a new “friend” at Apple support who i speak with and email at least once a day!! I had read somewhere else about magnetic cell phone cases possibly causing a problem but put it in the back of my mind. I drove to work one day disabling the auto lock and leaving the phone on my dashboard to see when exactly it would lock up and surprise…no lock up. My husband took my phone today (without the case) and he hasn’t had a problem. I was about to replace the phone AGAIN but i’m gonna try it this weekend without the case and see what happens.
    Thanks for all your input

  4. I have seen conflicting information about magnets effecting the phone. We have obviously experienced that the magnet does have a negative effect.

    My current case has a magnet in it and it does not effect the phone. However, this magnet is much smaller and not as strong as my original one.

    I hope your testing shows that the case is the problem and that you can get another case to solve the problem. Glad this helped.
