how to activate the reserve battery in nokia mobile phones? what to type and where to type. i tried typing *3370# in the screen, nothing happened! then i called this number *3370#, it displayed "request not complete"!!! will it work on all models? or should we type this code only when the battery gets completely dead and the phone switches off on its own?

This code does not access a secondary battery hidden within the phone but is a way to increase the life of your main battery. If your battery is already dead entering this code will not help at all.
The claim that pressing the sequence *3370# will unleash "hidden battery power" in a cell phone seems to be a misunderstanding of an option available on some brands of cell phone (such as Nokia) for Half Rate Codec, which provides about 30% more talk time on a battery charge at the expense of lower sound quality. However, this option is enabled by pressing the sequence *#4720#. The sequence *3370# actually enables Enhanced Full Rate Codec, which provides better sound quality at the expense of shorter battery life.

Dear friend,
There is nothing called reserve battery in nokia.or any phones.There could be a reserve petrol in a car but not in mobile phones.
Have you ever heard of this reserve battery in any of the mobile phone advrtisements? never.
Its a myth.
