Anecdotally I've had batteries expanded in two Apple devices (disclaimer: I don't keep many other devices around). The video makes a case for Samsung devices being prone to it in near ideal conditions, but normal people tend to take a lot less care, use them in rougher environments as well and stressing things a lot more, especially as these devices are not used 3 weeks for testing and stored away as reviewers would do. I think we should expect most of our devices to potentially have the issue at some point, whatever the maker. Even on the safer devices, there must be a point where it just happens.
