Overview

Green Mode Manager (GreenModeMgr) allows devices to be configured to help minimize power consumption. This is done by scheduling power to be supplied to the parts of the device that use the most energy only when those parts are expected to be active, and/or by shutting off components when device sensors indicate certain conditions.

Main Functionality

  • Set schedules for supplying power to:
    • Bluetooth radio
    • Cellular (WWAN) radio
    • NFC radio
    • Peripherals connected to the device
    • Wi-Fi (WLAN) radio
  • Set device to turn off display:
    • While charging
    • At a specified time
    • When idle for a specified period
    • When placed face-down for a specified period
    • When a low-light condition is detected for a specified period
  • Automatically turn off WWAN radio whenever device connects to a Wi-Fi network
  • Automatically dim display backlight if a low-light condition exists for a specified period
  • Automatically dim display backlight if Adaptive Brightness is disabled in the Android Settings panel

Green Mode Manager is NOT supported on SDM660-platform devices. See a list of Zebra devices by platform.

Screen-off When Face-down

Controls whether to turn off the device screen when the unit is placed with its screen facing down for the length of time specified in the Face-down Delay parameter (below).

Note: Not supported on SDM660-platform devices.

Parm Name: ScreenProximityState

Option Name Description Note Status Requires
0 Do not change This value (or the absence of this parm from the XML) causes no change to settings; any previously selected setting is retained.

MX: 15.0+

1 Turn On Turns off the screen when the device is placed with the screen facing down.

MX: 15.0+

2 Turn Off Leaves the screen on when the device is placed face-down.

MX: 15.0+

Face-down Delay

Used to enter the duration in seconds (from 1–60) that the device must remain face-down before the screen automatically shuts off.

Parm value input rules:

  • Integer from 1–60

Note: Not supported on SDM660-platform devices.

Shown if: Screen Proximity State is "Turn On"

Parm Name: ScreenProximityDelay

Requires:

  • MX: 15.0+

Screen Auto-dim

Controls whether to automatically dim screen brightness when ambient light sensors on the device detect a low-light condition to the level specified in the Auto-dim Percentage parameter (below).

Behavior Notes

Behavior of this parameter varies based on the Adaptive Brightness setting in the Android system.

  • If Adaptive Brightness is ENABLED when parameter is applied:
    • Brightness is immediately reduced by the specified percentage (or to 30 percent, whichever is greater)
    • Screen brightness adjusts according to ambient light conditions
  • If Adaptive Brightness is DISABLED when parameter is applied:
    • Brightness is immediately reduced by the specified percentage (or to 30 percent, whichever is greater)
    • Brightness remains at the same level unless changed by the device user or a new setting is applied

Note: Not supported on SDM660-platform devices.

Auto-dim Percentage

Used to enter a number of percentage points (from 10–30) to dim the screen brightness from its current level. For example, entering 30 reduces the brightness to 50 percent on a device previously set at 80 percent. Screen brightness is NEVER set to less than 30 percent, regardless of values entered in this parameter or current brightness level of device when this parameter is applied.
