iPhone 8 owners in Japan, Taiwan, China, Canada, Greece, and Hong Kong have now reported iPhone 8 battery incidents, PocketNow. Apple confirmed it’s investigating these cases. At least one of these iPhones presented the issue right out of the box. In other cases, the phones were either charging or suffered a short fall with little damage before the battery expanded.
At least seven iPhone 8 battery swelling incidents have been reported since Apple launched the new phones on September 22nd. The number seems big but it’s still not statistically relevant, given the millions of iPhone 8 units that Apple has undoubtedly sold so far.
