Recently we had heard that there were two reports of iPhone 8 Plus owners experiencing swollen batteries to the point where it actually pushed open the chassis of the iPhone. However it seems that there are now more reports of such incidents happening coming from various parts of the world such as China, Canada, and Greece.
However we should point out that in addition to the two that was previously reported, in total there are only six such reports out there so far, or at least the ones that have been officially reported. This means that it is probably not a widespread issue, especially when you consider the fact that it only represents a fraction of the millions of iPhones that Apple has probably sold so far.

According to Sam Jaffe, managing director of Cairn Energy Research Advisors who spoke to The Verge, “[Swelling is] very unusual for a brand-new battery and leads toward the direction of there’s something fundamentally wrong with this battery,” although hopefully that isn’t the case. Manufacturing defects aren’t exactly new and there are bound to be a few faulty units that are missed during QA, which like we said isn’t surprising when there are millions of devices that are being churned out.
Thankfully apart from the swollen batteries, there have been no reports of explosions yet so for now it seems that Apple has managed to avoid a situation like Samsung’s Galaxy Note 7 last year. The company has since stated that they are looking into it.
