The FRITZ!Box offers various ways to save energy. The modules of the FRITZ!Box adapt their power consumption to current use and reduce it when less power is needed.
This page shows the percent of the maximum power consumption the modules are using, currently and on a daily average.
The maximum power consumption value assumes that all functions are in operation.

FRITZ!Box System Overall

The graphic shows how much energy all of the FRITZ!Box features are consuming currently and on average.

FRITZ!Box Central Processor

100% consumption means that the CPU is working at full capacity. If the value is lower, consumption is correspondingly lower.

WLAN

The graph shows the current energy consumption of the WLAN module of the FRITZ!Box.
Since the WLAN module masters "Green AP Mode", it is especially energy-efficient: As soon as no more WLAN devices are connected with the FRITZ!Box, the energy consumption of the WLAN modules is automatically reduced to a minimum. "Green AP" operation has no effect on the accessibility of the wireless network for WLAN devices, since the new registration of a WLAN device automatically ends the mode, thus restoring full WLAN functionality to the FRITZ!Box.

DSL

As soon as no more data are being exchanged with the Internet, the FRITZ!Box reduces power consumption. However, power consumption can only be reduced if your DSL provider supports energy-saving measures.

The L2 mode is a power-saving function of ADSL2+.

Analog Extensions

100% capacity means that each analog extension is currently in use, for a telephone call, or to send or receive a fax. Non-active extensions do not use any energy.

USB Devices

All of the USB devices connected to the FRITZ!Box have a total of 2500 mW available.

LAN Ports

The LAN ports consume power when the connected devices are switched on. As soon as a device is turned off, the interface to this device no longer requires any power.

Statistics

In addition to the information about energy consumption, the three diagrams in this section also show how certain device parameters of the FRITZ!Box change depending on the actions performed with the FRITZ!Box.
Interested users can watch the how these changes are related over time and observe how the FRITZ!Box is affected by, for instance, simultaneously making telephone calls, surfing and streaming data. The "CPU Usage" graph shows the demands placed on the FRITZ!Box's main processor, while "Temperature" shows the relative temperature development of the FRITZ!Box and "RAM Allocation" indicates how the main memory of the FRITZ!Box was used.
