Apple to investigate social media claims of swollen batteries on the iPhone 8 Plus91
In one of the examples, the owner of the phone said that the swelling occurred while he was charging the handset using an official Apple cable and power adapter. According to the second iPhone 8 Plus owner with a swollen battery, his phone came straight from Apple with the screen popped out and the cell inside the phone blown up to a multiple of its normal size. Apple's decision to investigate the swollen batteries is not out of the ordinary. According to someone in the know about Apple's policies, the tech titan routinely examines even older iPhone models that are presented with a swollen battery.
Coming just about a year after battery issues torpedoed the Samsung Galaxy Note 7, forcing Samsung to recall the phablet twice before taking it off the shelves for good, some are quickly attempting to connect the swollen power source inside the iPhone 8 Plus to the cells that were inside the Galaxy Note 7. However, unlike Sammy's 2016 high-end phablet, the number of affected iPhone 8 units is well within the normal failure rate for lithium ion batteries. The Galaxy Note 7 failure rate was 1 in 20,000 units while currently we have just two iPhone 8 Plus units involved out of millions produced. For now, there is absolutely no connection between the Galaxy Note 7 and the iPhone 8 Plus.
