Three more reports of swollen batteries in iPhone 8 Plus surface, still not statistically ...

Three more reports of swollen iPhone 8 Plus batteries have surfaced in international markets, but the current rate of failure is still well within industry norms for infant failure of lithium ion batteries.




Three of the social media reports and two from MacRumors readers depict a swollen battery displacing an iPhone 8 Plus screen out of its housing. Four claim that the devices in question were being charged with an official cable and power adapter, with one earlier claim that it was received with a swollen battery.

Prior to AppleInsider's Saturday's report about the first two accounts of swollen batteries, a source within Apple not authorized to speak on behalf of the company informed us that Apple investigates swollen batteries even on older phones brought into Apple retail stores as a matter of course.

At present, the failures appear to be "infant failures" -- meaning failures within the first 30 days of production of the device. AppleInsider has learned that another possibility is mishandling of the device in shipping -- but there are no solid numbers failure rates from that, or any good way to glean that data outside of Apple diagnostics.

The normal infant failure rate of lithium ion batteries is about one in one million, so the existing failures are still well within statistical probability, assuming all of the accounts are accurate regarding charging equipment and the devices were not mishandled somewhere in the shipping process.

A more in-depth poll of ten Apple Genius Bars that we have worked with in the past still show zero iPhone 8 or iPhone 8 Plus models brought in for service with a swollen battery such as that displayed in the pair of reports.

Reading data gleaned as part of a different report from about this time last year, the same stores had four iPhone 7 and iPhone 7 Plus models come in for service with swollen batteries after the launch of the device, with the number tapering to two between all the stores in late October and early November. All but one of the iPhone 7 and iPhone 7 Plus models that came in for service at our polled Apple Stores were ultimately attributed to either user mishandling or abuse during the shipping process.

There are no reports of fire or property damage beyond the iPhone as a result of the swollen batteries at this time.

Several factors can cause a battery failure over time. In many cases later in a iPhone's life, an off-brand charger or cable can contribute to battery failure, as can mishandling by the user. There are no good numbers on lithium ion battery failure rates as a function of use, but calendar age and use pattern are also factors.

Apple has confirmed that it is looking into the situations surrounding each failure, but has so far declined to provide any more information.

The reported failure rate on the Galaxy Note 7 exceeded 1 in 20,000 with many of the failures causing explosive off-gassing of battery electrolyte. The root cause of the bursting phones was linked to both battery production problems and a design problem with the phone.

    I hope to God the babies' batteries are ok?!?! 😜

    In other news, Apple is looking into reports that as many as 3 buyers of the iPhone 8+ were not completely satisfied.

    I guess better swollen and coming apart than setting your house on fire...

     My iPhone 6 arrived bent in the box. And this is during the so-called "bend-gate".  No one cared except me.  Apple replaced it NQA.  

    I didn't post to social media.

    “Not statistically significant.”

    Why are we reporting this?

    I mean seriously.  This is basically a 4 year old phone.
    Your comment is child like in its misunderstanding of the world. It’s a brand new phone, and there are always some battery failures. 3-5 out of millions is nothing. So clueless. 

    And anybody using the children’s version of a grown man’s name sounds like a fucking idiot.

    Just out of curiosity, was the number of failures for the Galaxy Note 8 'statistically significant?' I'm also curious if the battery supplier for the iPhone 8 is the same as the iPhone 7. Since the mechanical designs are virtually identical and the batteries are close to the same size, it seems like we would have seen similar reports with the iPhone 7. Of course, that's assuming there's not reporting bias, which is a big assumption. Even if the incidence is within the range of expected failure, public perception is far from rational

    Presumably you mean the Note 7? That being the one infamous for exploding batteries. From the end of the article:

    The reported failure rate on the Galaxy Note 7 exceeded 1 in 20,000

    Especially because there are more and more phones delivered.

    You mean troll squatters  like those here and in almost all online place where you can put down an opinion  and clickbait junkies like you got everywhere else, Youtube, media, all so called "news" sites.

    Oh, and there were many of those that caught fire (the Note phones), seems to be something a bit different too...

    Like I said, swelling eventually occurs to most battery if you keep your device long enough (with enough charge cycles); how it happens makes one hell of a difference. Popping screen vs puncture battery and fray wires is one hell of a difference.

    Doesn't mean they should ignore it of course. But, it's Apple and we are in social hell were we have to know when everyone's taking a dump, so of course we will know about it... Instead of like in the past, just going back to the store and getting the phone exchanged.

    darn, I was hoping there would be hundreds of cases to drive down the APPL stock price so we mortals can buy some on the cheap heading into the X preorder weekend. Battery Gate, I beg you, please.

    Only if you have no clue. Then, yeah, in your fertile imagination, it will be  "no good"...

    The same reason we always do when the rest of the media flips out for no good reason about something Apple has done or has not done.

    You have to do better than just 3 phones, than... Much better!

    Note 7 statistically significant: 1 in 20,000 conservatively. Probably closer to 1 in 15,000.

    Battery supplier: Doesn't look like it.

    Mechanical design: Nope. Many differences. Similar battery size, but similar size does not equal the same size or the same issues.

    Similar reports with the iPhone 7: We did.

    Reporting bias: The five who have had the problem posted. The 20 million+ who haven't, didn't.

    Agree with public perception -- thus the explanation of what an infant failure is.

    But...you are the media...spreading the story... Despite the three-word qualifier, it's still spreading this story across new feeds across the globe. For a non-event. 

    Sorry but it just looks like your own flavor of clickbait to me.

    Because the long knives are out and this is a prime example of FUD in action. After the Samsung debacle the tech media is out for blood and anything they can smear Apple with needs to be trumpeted from the rooftop. AI, and iMore are at least trying to explain the situation.
