MJ, not mJ. 2.5mJ is roughly the energy of a single keyboard keypress. 2.5MJ is over half a kilo of TNT.

Fun fact that Wolfram alpha just informed me of: a phone uses between 10 and 20 MJ a year: multiple kilos of TNT. 4000mAh * 3.7V * 365: yep, it's about right.

Oh, oops that's a mistake, thanks for catching that.

Also, interesting fun fact indeed.
