Netgear AC815S – AT&T Unite Explore™ User Manual

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.

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).

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:

Set the Wi-Fi range to Standard, not Extended, and set the Wi-Fi standby to 5 minutes.
