It's pretty normal for Lithium Ion batteries to swell. You see it constantly with smartphones especially, where it's very obvious given the tight tolerances in modern devices. I say this as someone who's worked with racks and racks of smartphones used for testing. Eventually they pretty much all swell.
- tigershark 7y agoMmm...my iphone 4 didn’t swell after it was used for 7 years.
- whynotminot 7y agoI will take your one phone as disproving all of my experience. Thanks! In all seriousness, I have an iPhone 4S whose battery is in tatters but also hasn’t swollen (that I can tell, anyway). It doesn’t happen to every single battery. It does happen to a significant portion of them over time.
