With GSM off, approximately 8 mA is drawn and the battery should last for something like 150 hours from fully charged battery when new. > > Hm, so basically your point is that CC allows current measurement in > > suspend.

I said I'm a > normal user :-) CC = Coulumb counter. Measures the flow of charge to/from the battery. TP = test point. Makes a signal of interest on a PCB available to probes. DMM = digital multi meter. Measures voltage, current, resistance and such.
