3 FCDEV3B:
4
5 CS Mode0:
6
7 boot-up with all sleep disabled: 40-42 mA
8 AT%SLEEP=1 after such boot-up: 17-19 mA

17
18 SIM and radio bring-up after deep sleep followed by AT%SLEEP=0:
19
20 after AT+CFUN=1: 30-31 mA until it settled back down to 27-28 mA
21 registered idle: mostly in the 28-35 mA range

23
24 Pirelli DP-L10:
25
26 Registered idle with Pirelli's original fw: down to 75 mA with
27 both LCD and keypad backlights on, unmeasurable (deep sleep) otherwise.
