+All measurements made with bench power supply set to 3.84 V
+
+FCDEV3B:
+
+CS Mode0:
+
+boot-up with all sleep disabled: 40-42 mA
+AT%SLEEP=1 after such boot-up: 17-19 mA
+AT%SLEEP=2: down to 11 mA
+
+after first deep sleep cycle:
+
+no sleep: 27-28 mA
+small sleep: 3-6 mA
+big sleep: 0-3 mA
+deep sleep: unmeasurable
+
+SIM and radio bring-up after deep sleep followed by AT%SLEEP=0:
+
+after AT+CFUN=1: 30-31 mA until it settled back down to 27-28 mA
+registered idle: mostly in the 28-35 mA range
+in a call: 72-86 mA
+
+Pirelli DP-L10:
+
+Registered idle with Pirelli's original fw: down to 75 mA with
+both LCD and keypad backlights on, unmeasurable (deep sleep) otherwise.
+
+FreeCalypso fw via fc-xram:
+
+XRAM download: 125-133 mA
+CS Mode0 with all sleep enabled: 87-94 mA
+CS Mode0 with AT%SLEEP=1: 99-101 mA
+CS Mode0 with AT%SLEEP=0: 117-118 mA
+registered idle with deep sleep: floor down to 87 mA, with activity spikes
+
+C139 running flashed FreeCalypso fw, all sleep modes enabled:
+
+CS Mode0: unmeasurable draw (deep sleep)
+small sleep during 10 s UART timer: 0-2 mA
+during AT+CFUN=1 process: 4-6 mA
+deep sleep during registered idle: unmeasurable draw
+in a call: 47-67 mA
