Users are slowly getting their hands on their pre-ordered iPhone 7s and iPhone 7 Pluses, and some of them are already complaining of hissing noises. That’s right, some units seem to be making a hissing noise that seems to come originate from around the Apple logo. Users say the hissing is noticeable when the phone is under a heavier load, such as watching video or playing games. One user, Stephen Hackett, uploaded a YouTube video exhibiting the issue and also went to the Apple store to have them investigate.
I just came back from the Apple Store. They had no idea what it is and what could it be (not surprising as this phones just came out today), so they ordered a replacement phone for me /: They could reproduce the issue easily. Also I noticed that when turning on the phone you can hear it very well, I guess because of the extra processing that is being done while booting the device. Kind of disappointed they don’t have a few in stock for cases like this, but on the other hand it sounds like an issue more common than 1 damaged phone. so I hope that if it is a faulty batch or something like that so the wait my pay off and by the time I get my replacement phone it will be fixed.
So far the consensus seems to be the noise is being caused by A10 “coil whine” which happens with most electronics though is usually not audible to our hearing. Even if this is “coil whine,” there’s something not quite right here and as of yet, Apple has not responded to requests for comment. We’ve yet to receive our unit, pre-ordered from T-Mobile, but we will be on the lookout for this problem once we do get it. We’ll be sure to touch on the issue if it exists in our full iPhone 7 Plus review.
