Low stand by time/ operation time
Low standby/ operation mode time
check power consumtion of the phone:
off state > 0-1mA
sleep mode > 2-8mA
 call mode GSM 900 / GSM1800 > 0-1A
check consumtion of 
N700 > lift R745
G700 > lift R741
G702 > lift R742

refer to section: "not 
charging (2)"
refer to section: 
"RX TX failures"
Calibrate RX and TX 
values of the phone
Note: The standby time depends also on the network side, like: PRP (paging repeat 
period time), signal strength (min -98dBm), location updates
and on the user handling of the phone (lights on or of, memory activities, games etc.)
