I did not use my iPhone4 for a while (since I have a Samsung Galaxy S4 now, which I like much more), and when I wanted to “revive” it recently as a music player I found that it had burst (no, I didn’t drop it, it was just lying around on my desk):

Obviously the battery had swollen…

I immediately called the Apple dealer closest to my home and told them about it. They said it’s normal for a battery to burst if the device hasn’t been used for a while. They said I could buy a new iPhone 4 for a “mere” 190 EUR… 🙁

If you Google for this issue you will notice that it’s pretty common, still Apple cares a sh*t about it… I’ve never seen such major battery issues on any mobile phone I’ve owned before — and I had many!!!

Thanks, Apple. This is what you get when you buy from a “premium” manufacturer…

Needless to say that I will never buy an iPhone again…
