Extend Battery Life
The mobile hotspot, by default, is configured to optimize battery life. The following
factors affect battery life:
Screen brightness.
•
Standby time.
•
Data throughput.
•
Mobile broadband signal strength (the better the signal, the longer the battery life).
•
Wi-Fi range.
•
Dual-band Wi-Fi (when all of your devices support 5 GHz Wi-Fi, dual-band Wi-Fi
•
allows faster downloads but uses more power).
Guest Wi-Fi, when enabled, uses more power.
•
To extend the battery life, use any of the following methods:
Adjust Wi-Fi settings.
•
Adjust display settings.
•
Use tethered USB with Charge and Tether or Charge Only enabled.
•
Adjust Wi-Fi Settings to Optimize Battery Life
If the devices that you are connecting to your Wi-Fi network are always close to your
mobile hotspot, shorten the Wi-Fi range. Set the standby timer to a shorter period to
minimize the wait time when no devices are connected to either Wi-Fi network before
going into standby mode (the Wi-Fi radios turn off).
Note: When you change the Wi-Fi settings, any devices connected to the mobile hotspot
are disconnected and might need to be reconnected.
You can set the following Wi-Fi options to optimize battery life:

General Questions
Review these topics for answers to general questions about the mobile hotspot.
Why isn’t my battery charging?
If you are in a low-coverage area, are transferring a lot of data, or left the mobile hotspot
in a hot location, the internal temperature of the mobile hotspot can rise above 45°C.
In these conditions, the battery cannot be charged due to safety limits with lithium-ion
battery technology.
User Manual74Frequently Asked Questions
Page 75
AirCard 797S Mobile Hotspot
Check to ensure that the USB cable and the AC wall charger are connected securely
and are working correctly.
If the device is left charging for over seven consecutive days, the device automatically
enters a battery longevity mode to enhance the life of the battery. During this state, the
device stops charging and allows the battery level to drop to and maintain at
approximately 75 percent. The next time the device is plugged into a charger, it resumes
charging.
Why is the Signal Strength indicator always low?
Your mobile hotspot’s reception is poor. Try moving it to a location with a clear view of
the sky (for example, near a window).
Why is the download or upload speed slow?
Data transfer speed depends on signal strength and interfering radio sources like
electrical generators or other mobile hotspot Wi-Fi devices. Review the following
possibilities:
Check your signal strength and network type (for example, LTE 4G is generally faster
•
than 3G).
Check Wi-Fi interference by powering the mobile hotspot off and on to find a better
•
Wi-Fi channel.
Change the Wi-Fi band from 2.4 GHz to 5 GHz.
•
The LCD screen is not lit. How do I know if the mobile hotspot is still powered on?
The LCD screen dims to save energy. The LED continues to blink slowly to indicate that
the mobile hotspot is still powered on. To wake the mobile hotspot, press and quickly
release the Power button.
How do I find my computer’s IP address?
The steps for finding your computer’s IP address depend on the operating system. If
your device runs an operating system not listed here, see the appropriate operating
system documentation.
