Description:
System Activity Monitor (TM). It's like the Activity Monitor on your Mac but for your iPhone.
You can view:
- Runtime (RAM) memory usage
- Storage (Disk) usage
- All running processes
- CPU usage
- WiFi IP address
- Device information
Memory types:
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.
