  • Go to iPhone’s “Settings” > “General” > “About” > “Diagnostics & Usage” > “Diagnostic and Usage Data”. This will show you a complete list of system process activities. Look for a particular process which has an unusually large number of entries. Do a bit of research on this process and identify its function.
