Is it possible to access past iOS logs? I know that you can get live logs from XCode, LemonJar, or cfgutil, but these are all in real time.  Is there any way to access logs from before the phone was plugged into the computer?

Thanks!
You can redirect all logs to a file so that you can see it when needed. So you can resolve any issues come in future.
