The state indication of the mobile data and WiFi icons on the system settings short-cut screen is inconsistent:

For Flight Mode and Bluetooth the icons mean:

• Lit (bright) = activated
• Off (almost dark) = deactivated

For mobile data and WiFi the icons seem to mean:

• Lit (bright) = enabled (connection may be there or not)
• Off (almost dark) = disabled (no connection)

(To get the current state you have to check the data connection icon on the lock screen or check the IP address: Only one data link is shown there. However you cannot be sure that the other connection option is not up as well -- and counting in case of time-based schemes or even available for incoming connection attempts, e.g. ssh.)

Possible solution:

There is an "intermediate" icon state, as seen when flight mode is activated: WiFi and mobile data icon are both darkened but differ now. This should be used for all 4 icons:

• Lit (bright) = activated
• Lit (between almost dark and bright) = stand-by (to be activated when needed; no status for flight mode)
• Off (almost dark) = disabled

Just to make clear, which screen I am talking about (taken from Mobile Data icon "greyed out" on Settings app cover even if switch is ON):
