Tentative Design

Device Status

Indicates the power status of the device itself.

• The string indicates whether the device is charging or dischargin, and gives a time until it will be completely full or drained.

• A message is displayed when a secondary battery is either empty or full (indicating that the battery can be removed).

  • Your secondary battery is empty

  • Your secondary battery is fully charged

• The charge indicator bar shows the current charge level as a proportion of the total possible charge. (When running off a UPS, the indicator bar displays the UPS charge level.)
  • The colour of the bar indicates the charge level. These colours correspond to those used in the icon theme:

• All indications of charge levels (either time remaining or the indicator bar) are composite figures if more than one battery is present.

Connected Device Status

This section indicates the power status of connected devices. It follows the same design patterns that are used for device status.

• Where charge/discharge time cannot be reliably predicted, descriptions of the charge level should fall back to a simpler vocabulary:
  • Non-rechargable devices - 'Full', 'Good', 'Low', 'Empty' (?) (avoid using the 'Caution' status)
  • Rechargeable devices - 'Charging - Full', etc
