depends on network settings (e.g. TPC Pattern) and data
transfer rate.
HSPA DATA HSPA data transfer in progress. Power consumption
depends on network settings (e.g. TPC Pattern) and data
transfer rate.
LTE DATA LTE data transfer in progress. Power consumption

Power Down Normal shutdown after sending the power down command. Only a voltage regu-
lator is active for powering the RTC. Software is not active. Interfaces are not
accessible. Operating voltage remains applied.
