Bloated Battery

This S7 was dropped hard, smashing the rear case and causing the battery to fail. After the drop the S7 wouldn't charge or stay on for very long, the most likely reason for bad batteries in these devices is because a small piece of foil ruptures with shock and causes the two electrodes of the battery to touch, overheat, and create problems.

Unless you're really comfortable working with at-risk lithium batteries. If the battery bends a fraction of a millimetre too much, you could rupture that same small piece of foil and start a chemical fire or explosion. This problem has only been intensified with the S7 Edge as that foil simply failed too easily.

Fortunately, there was no exploding batteries or damage apart from a very bloated battery. The S7 was back to fully working condition soon after a new battery was installed.
