The only time battery drains is when I use 3G. So much so that I have stopped using it altogether ...
Lol

Well I use only 2G , that too with data connection off.
I have changed the ROM to the stock zip by iONEx, still the battery drain and unresponsiveness exists.
Today I have faced a new bug:
Sometimes while calling someone, there's no volume, no dial tone, nothing.
Similarly sometimes when someone calls me there's no ringtone, there's only vibrations; when I pick the call, the incoming call screen still remains and suddenly the device reboots and stays unresponsive till next reboot
At the moment changing to extended or Kappa and waiting for a fix thanks in advance :good::fingers-crossed::laugh::highfive:
