to get some interesting information about your phone and battery.

*2767*3855#
Think before you give
this code. This code is used for factory format. It'll remove all files and
settings including the internal memory storage. It'll also reinstall the phone
firmware.

WARNING: Never use
the first option otherwise your phone camera will stop working and you'll need
to take your phone to service center to reinstall camera firmware.
5. End Call/Power
*#*#7594#*#*
This one is my
favorite one. This code can be used to change the "End Call / Power"
button action in your phone. Be default, if you long press the button, it shows
a screen asking you to select any option from Silent mode, AirPlane mode and
Power off.
You can change this
action using this code. You can enable direct power off on this button so you
don't need to waste your time in selecting the option.
