FEATURES

Runtime memory usage. The iPhone and iPod Touch (device) comes with two types of memory, runtime memory (RAM) and storage memory (Flash). Your device has only 128 MB of RAM which has to be shared by various applications and processes when they are running. Your device has 8 GB to 32 GB of Flash memory which is used for your music, video and application files.


The runtime memory usage is categorized into four categories, Free, Inactive, Active and Wired.

Free memory

This memory is not being used currently


Wired memory

This information can't be moved to disk, so it must stay in RAM. The amount depends on the applications you are using.


Active memory

This information is currently in RAM and has recently been used.


Inactive memory

This information has not recently been used but will remain in RAM until another application needs more memory but no free memory is available. If called upon by a process, this is quickly changed to Active memory; if it has been swapped to the hard disk, it will be moved back to RAM and marked as Active.


Page ins / Page outs

"Page ins/outs" refers to the amount of information moved between RAM and the hard disk. This number is cumulative amount of data that iPhone OS has moved between RAM and disk space.

PROCESSES

The processes list shows all processes and applications currently running on your device.


BATTERY INFO

The battery level is displayed as a percentage of the battery charge level. This is more accurate than the icon shown in the top status bar of your device.
