Shortened standby time.
The duration of standby
time is affected by your
service provider’s system
configuration. The same
tablet used with different
service providers' systems
does not have the same
duration of standby time
(LTE/HSPA+ only).
If you are located in an area
where the network signal is
weak, move your location to
the area where the network
signal is strong or temporarily
turn off your tablet if needed.
If you are not able to
connect to the network,
the tablet continues to send
out signals as it attempts
to locate a base station.
Doing this consumes battery
charge and consequently
shortens standby time.
Change your location to
one where the network is
accessible, or temporarily
turn off your tablet.
