1.5.1.6 VCC or 3.3Vaux current consumption in fixed active-mode (power saving disabled)
When power saving is disabled, the module does not automatically enter the low power idle-mode whenever
possible: the module remains in active-mode. Power saving configuration is by default disabled. It can also be
disabled using the AT+UPSV command (see u-blox AT Commands Manual [3] for detail usage).
The module processor core is activated during idle-mode, and the 26 MHz reference clock frequency is used. It
would draw more current during the paging period than that in the power saving mode.
Figure 10 illustrates a typical example of the module current consumption profile when power saving is disabled.
In such case, the module is registered with the network and while active-mode is maintained, the receiver is
periodically activated to monitor the paging channel for paging block reception.
