Let the Battery Die and Lose Your Email Settings

It seems that letting the battery die on my Sony Ericsson S710a is a bad idea. It doesn't happen often, but when it does, it can be a problem. I have the phone checking a POP3 account every 5 minutes. I think it was probably actively checking when the battery gave up on 2 seperate occassions.

When I power the phone back on, that primary email account is corrupted in that the settings are mostly blank, and I cannot get it to save the settings back. I end up needing to delete the account and completely recreating it from scratch. I think I'll be more careful about the battery, since tapping out all those settings on the keypad is time-consuming, and it sometimes takes me a day to realize that the email hasn't been checking.
