Have you been wondering same thing?
Well, if you have then this post should excite you.

It’s been proven that NO MATTER the phone you’re using, a defective or improperly handling of its battery can overheat, causing the cells to break open and result in a chain reaction of other cells rupturing.
Whether it has the best battery or the best power, they all work on lithium-ion technology, all rechargeable batteries do.
Eventually when the chain reaction occurs, it goes KA BOOM!!
Now, here is a video clip you should watch. Although it’s hilarious, but it’s more of a safety tip for both young and old.
In this video, a guy practically demonstrated how a phone battery could catch fire, when it is being poked. In the demonstration, a knife was used to poke a Samsung battery.
P.S: Don’t try this at home, cos your phone battery would die an everlasting death.

Another question for you;
Have you ever read the protection and safety guides at the back of your battery?
I know most of us usually don’t read those stuff, but phone manufacturers advise we do.
