In the Internet, there is a circulating forwarded email claiming that pressing *3370# on your Nokia mobile phone will activate your so-called spare battery which will give you 50% extra battery life.
Being the usual "inquisitive" guy, I decided to give it a try. So I pressed, *, 3, 3, 7, 0, #...
"Change active speech codec?"What the heck?? Since when a battery is called "active speech codec"? Well, there are only two options there, "OK" and "Back".
Being the usual "inquisitive" guy again, I decided to press on OK. 一不做,二不休 marr... DONG! Off goes the light, and the whole mobile phone restarts and the same screen reappears. Nahh, no change in my battery bars also, it's still at its original position, no "increase in battery life" as claimed by the e-mail.
So I decided that this is a hoax, just like those claiming that you can elongate some part of your body with some daily exercise. Some googling on this issue proved my guess: This code indeed does *something*, but it doesn't give you some magical power boost. In fact, the activated "speech codec" mode actually consumes more power of your little battery!
At the end of my daily dawdling, a lesson is learnt: Never trust anything in the Internet so easily. If not, your some parts may suffer. :D
