Lets see how many hours of calls you have made on your Nokia or Sony Ericsson mobile phone with the help of the Life Timer.
Dial *#92702689# (Spells warranty with a 0 replacing the second "r")
Press these keys in sequence. (Where "R" means right on the navigation/joystick and "L" means left of the navigation/joystick. "*" is an asterix next to the 0 key)
A number will appear in this format 00:00
The numbers to the left of the colon represent the hours.
The numbers to the right of the colon represent the minutes.
This number is the total call time made using that handset (not sim card). It counts both dialled and received calls together.
eg. 00001:34 means 1 hours and 34 minutes total calls made.
It cannot be cleared through "Clear timers" in the call duration menu nor through flashing/changing firmware.
It is used to judge the life of the phone and so that buyers know handsets advertised as "brand new" are actually brand new.
