Nokia E6-00 - What does the "Activate power saving" command do in my Symbian^3 phone?

When pressing the power key and selecting Activate power saving, the device settings are optimised to save the power by adjusting e.g. the following settings:

  • Network mode changed to GSM.
  • Bluetooth turned off.
  • WLAN scanning disabled on home screen. 
  • Display settings optimised by setting the light sensor value to minimum and shortening the light time-out.
  • Theme effects turned off.
  • Touch screen vibration turned off.

To deactivate power saving mode, press the power key, and select Deactivate power saving.
