hi all,
i received an email saying that if i dial the above.. the mobile phone will go for the "reserved battary" in nokia.
wondering whether anybody has verify this before. i am afraid to test on it as it may erase the entire memory.
*3370# ???
There is no "reserved battery" or "reserve battery" or "backup battery" to go to.

Try it and let us know what happens. haha
It most certainly will not erase any memory.
Didn't do anything on my N70 apart from come back "Request not completed"
tried *#3370# aswell but returned the same thing.
I do believe that putting that in lowers the signal boost or something, conserving more battery. It was used on phones like the 3310, etc. I remember when a rumour got spread around my school that if you type that in before making a call you got the call for half price 😛 As it was a secret code for Engineers phoning eachother!

yeah i had something like that around my school but it was a longer code & it stopped the sim clock,saw it work on a 6210!
wow! thks guys!
cheers!:icon14:
that code is something to do with turning EFR on and off.. 337 spells EFR on your phone..
EFR stands for Enhanced Full Rate speech codec used for voice encoding. The code for turning it on or off has no effect, because the phone doesn't really decide what codec is used. The network does and whatever the network tells the phone it should use, the phone uses.
This whole "reserve/backup" battery thing comes from the assumption that if one makes the phone to use a half-rate codec instead of the full-rate codec, it will use less power. Probably true to a very limited, minuscule degree, but in practice the whole idea falls down because today's mobile networks decide what codec they force the phone to use, and nothing you do on the phone can change that.
If you want details about the standardized speech codecs, etc., dig into the specs on http://www.3gpp.org/ if you wish.
