Don’t be alarmed, but the new iPhone 7 is making a mysterious noise

The new iPhone 7 was unleashed upon the world just days ago, but already there's something weird going on with them, apparently.

Some iPhone users who got the first tranche of the new Apple devices are reporting that their shiny new phones are making a very strange noise. There have been reports that some of the new iPhone 7 models are hissing at users. While there's no official explanation yet for what the hissing sound is and no word from Apple, it appears to be making the strange sound when the handset's processing power is pushed to the limit. It appears to have first been noticed by Stephen Hackett at 512 Pixels, who said: 'As my iPhone 7 Plus was restoring from iCloud, I thought I noticed some sound.

'After picking the device up from my desk, it was clear the sounds are coming from back of the phone, possibly from the CPU.

'It seems to get worse if the iPhone is under load.

'It’s loud enough to be heard even if the iPhone is just sitting on the table'.

The tech firm were quick to remedy the problem for Mr Hackett after he got on the phone (presumably a landline) to AppleCare and the firm said it would replace the handset.

But he's not the only one. YouTuber DetroitBORG uploaded a video purporting to show this bizarre noise in action.

Some have speculated that the sound may be emanating from the new A10 Fusion processor because it only appears to happen when the chip is placed under a heavy processing load, and the sound appears to come from the general area of the processor.

A video uploaded to YouTube by a user called DetroitBORG, claims to demonstrate the bizarre hissing sound coming from the handset.

People are speculating what's causing the new devices to hiss. But the most likely explanation is when the new A10 Fusion processor is put under a particularly heavy load.

One such instance, which seems to tally up with reports, is when people are restoring a new phone from a back up which uses a huge amount of processing power.

It's already being dubbed 'HissGate' on Twitter and follows on from similar 'gates' when Apple products launch including BendGate (remember that?) and the notorious AntennaGate.

People on Twitter were all making the same jokes... https://twitter.com/MagnifiKent_/status/777700322693160965 https://twitter.com/pratikshejwal/status/777911722514325505 https://twitter.com/CharterKubiya/status/777910228377448449 https://twitter.com/dawidbodych/status/777903268143910912 https://twitter.com/lazyboneslewis/status/777655597629968386 https://twitter.com/davidtjackson/status/777913176272801792 https://twitter.com/jramjee/status/777855769584758785 https://twitter.com/maxjany/status/777838598511001600 https://twitter.com/Rutwiz_/status/777738873170526208 https://twitter.com/MMASOCCERFAN/status/777856481169408000 Still, it could be worse to be fair... https://twitter.com/jakthebomb/status/777890553484587009 https://twitter.com/pg_72/status/777856341809520643
