Structure is:

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.

State	Example message
Charging & fully charged	Charging - fully charged
Charging	Charging - 55 minutes until fully charged
Discharging	Using battery power - 55 minutes remaining
Caution - low battery	$/!\$ Caution - low battery, 10 minutes remaining
Running on UPS power	$/!\$ Using UPS power - 5 minutes remaining
Low UPS power	$/!\$ Caution - UPS is low, 1 minute remaining
Running on UPS and battery	$/!\$ Using UPS and battery power - 40 minutes remaining

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.

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
