Some early iPhone 7 users are reporting that their brand new smartphone is making “hissing” noises at them. According to multiple reports, when the iPhone 7’s A10 processor is under heavy workload such as running a game, it will start making sounds that is similar to white noise.
This noise was first noticed by Stephen Hackett of 512 Pixels, who posted a video of the problem for users to hear. Other users, including TechCrunch’s Darrell Etherington, are also facing a similar problem. Fortunately, despite the annoying sound, the device is still fully functional.
The hissing noise does not affect all iPhone 7 devices though, Engadget says that they tried running 3DMark “Ice Storm Extreme” performance test on their iPhone 7, but did not hear any hissing at all. The Verge and iMore also reports that they couldn’t hear any noises on their iPhone 7 devices.
Apple has not commented on the problem, but it is believed that the sound is some sort of “coil noise” made by electronic parts when they are not properly dampened. Lifehacker says that there’s really no fix for the problem but thankfully, Hackett got his unit replaced by AppleCare, so you might be able to replace it though, you might need to wait for a while.
It’s great to be an early adopter, to be the first to get your hands on a device with limited availability, but I guess that this is the sort of risk users must take.
