My iPhone charged from 98% to 100%?

So I just literally saw my iPhone charge from 98% to 100%(full)… Is this normal? I've never had that happen before. Has anyone had that happen to theirs? I even downloaded an app afterwards to check the accuracy of the battery charge and it said it was fully charged also.

I think your iPhone has been infected with a virus. It might short-circuit and catch on fire. This is a very serious situation, I think.

When you leave your ipod alone, as in don't touch the screen at all, the battery starts going up super slow and somtimes just pops right up like how you said
