Personally, I noticed that I can see and feel the "shape" of the battery in iphone as compared to Samsung after about 1.5 years. This might means the casing material "play" a big role to cater for battery expansion/heat. I didn't go in detail...

My takes is that the battery heated-up due to activities (charging, running apps, etc.), which resulted in battery expansion but it is between casings/items thus the "expansion force" is forced inwards, towards the layer of "insulator" between the cathode and anode, resulted breakdown of the layer. Hence, this problem is not a result of how many percent of power the battery is at. Just my opinion.

based on official story, the anode and cathod came in "contact" = MFG error... how could that happen?  the whole idea of battery is anode and cathod should not in contact... tolerance issue? how could that be MFG error, if it is, why is not caught during testing? battery short (in
contact) should be easy to catch, we are not talking about charge leakage here... how it escaped?  more question than answer... (don't tell me SI to empire conversion or round up error stuff like that...).  not small gap,but in contact... must be lost in translation...
