I don't know its bug or what, but seems our battery shows wrong info about charging it.

Before when i used to charge it to 100 % it used to take 24hour to down to 50% and also suddenly shut down if goes below 10%
But if you charge your phone for 30 min beyond 100%, you will get 30% extra backup,
and my phone takes 36 hours to go down to 50%.

So i think our phone lies about charging capacity. Some battery calibration error or something is there..
