I don't know about you, but I always carry hammers in my pockets. So, clearly it's important I know how a smartphone will stand up to a hammer. Enter TechRax, who took it upon himself to do a hammer test on the Galaxy S5. The lesson we can all learn from this: don't hit high-density lithium-ion batteries with hammers. Just watch the very end... trust me.
Ignoring for a moment that this is a completely unnecessary test, batteries are seriously dangerous when damaged.
