Overview
The Battery Usage pane in the Xcode Organizer shows a breakdown of the appʼs foreground and background power use, giving you a starting place to optimize power consumption.
The top graph shows the on-screen use, and the percentage of battery used during a 24-hour period while the app is in the foreground and the device isnʼt connected to power.
The bottom graph shows the background battery use during the same 24-hour period.
Clicking on a bar for a previous version shows a comparison of battery use to the right of the graphs. The zoomed-in section above shows an example of this data. The percentage values for each version are followed by a category breakdown. Larger values are shown in bold for easier comparison.
The power use categories are:
Audio: Used to play audio in your app
Networking: Used for networking
Processing: Used by the CPU and GPU
Display: Used to show the application UI
Bluetooth: Used for Bluetooth
Location: Used for location tracking within your app
Camera: Used by the camera within your app
Torch: Used for the flashlight
NFC: Used for NFC within your app
Other: A combination of the power in the above categories thatʼs too small to show in the list and any other power use
