Usage question

[Markrose]

How do we use the usage battery statistics? It says since last full charge. I get that. What I don't get is standby and screen on are separate. Do we add both up for total time on battery, or just use standby time for total time?

Edited to correct original erroneous statement (nightstalkerz correct post below caused me to investigate further!) The "Viewing Usage Statistics" section of the following has details: http://www.apple.com/batteries/iphone.html

Standby is the total time the device went off charge. This includes the usage time.

Usage time is mostly when the screen is on or when its doing some when the screen is off like a backup.

The usage time is always less than or the same as the total time.
