Apple is investigating reports of its new iPhone bursting open, days after the flagship device went on sale.
Pictures on social media showed an £800 iPhone 8 Plus handset that appeared to have split alongside the side.
One owner said the device’s casing cracked open as it was charging, according to Taiwanese media.
The phone had reportedly been in use for five days and was being charged with an official cable and power adapter.
Another customer, from Japan, said their iPhone 8 Plus had been delivered to them with the screen already partially detached.
They posted pictures on Twitter showing the phone split along the side.
Apple confirmed it was “looking into” two reports of the issue but declined to comment further to The Independent.
It is understood the tech giant believes the problem was caused by the battery swelling and does not pose a safety concern.
It is not yet known whether the reported issues are isolated cases or indicate wider manufacturing problems.
Apple began shipping the iPhone 8 to the first customers two weeks ago ahead of its official 22 September release date.
The handsets look very similar to the iPhone 7 and 7 Plus, but feature wireless charging and improved cameras.
A user from Taiwan claimed her iPhone 8 Plus, which belongs to Apple’s latest line-up of devices, split open while it was charging. “So far, the finger of blame is being pointed at the battery. Unconfirmed reports state the iPhone 8 Plus uses the same battery manufacturer, Amperex Technology Limited (ATL), as the Samsung Galaxy Note 7”, The Next Web reported late on Friday. The screen of the device bulged out five days after the user purchased it.
The woman had purchased a 64GB “Rose Gold” iPhone 8 Plus and she put it on charge, using the supplied cable and adaptor. “After about three minutes, she reported seeing the front panel bulge, and eventually lift completely from the device”, the report added.
The Cupertino-headquartered giant is currently investigating reports of iPhone 8 Plus splitting open and the reason remains unclear as of now.
Similar reports have emerged from Japan where one owner claimed his phone arrived in a state with the screen visibly detached from the body. However, there have been no reports of visible evidence of burn marks.
Apple iPhone 8 and iPhone 8 Plus were made available from September 22 in the US, Australia, Canada, China, France, Germany, Hong Kong, Singapore, United Arab Emirates, the UK and other countries.
