It has been reported that the new iPhone 7 Plus is emitting noise from its logic board, resulting in a hiss-like humming getting louder if the phone is under load, 512 Pixels has said.
According to the blog post's author Stephen Hackett, the hum is loud enough to be heard even if the iPhone is face-up on a desk.
Hackett said he first heard the sound after he was restoring the new device from an iCloud backup. Having heard of others experiencing similar issues with previous iOS devices, Hackett said it is the first iPhone for which he has raised a concern relating to hissing.
After contacting Apple, the tech giant is replacing Hackett's device.
The original iPhone started with 4GB of storage, while the top-of-the-range iPhone 7/7 Plus now offers 256GB of storage.
The iPhone 7 also features a 4.7-inch Retina HD display, quad-core A10 Fusion processor, 7-megapixel FaceTime HD front-facing camera, 12-megapixel rear camera with 6-element lens, a non-physical Home button featuring Force Touch feedback, and water- and dust-proofing to IP67 standard.

Apple unveiled the new iPhones on Wednesday in the United States, with one of the most notable changes to the handset the removal of the headphone jack, with Apple to now connect headphones over Lightning, which is now used for power, audio, and control.
"Some have asked why we would remove the analogue headphone jack from the iPhone. It has been with us a very long time," said Apple's marketing chief Phil Schiller.
"The reason to move on comes down to one word: Courage."
