After switching to iWeb, I setup my iPhone to get my email on their IMAP server.
I have made a typo when entering my password for outgoing email. After trying to send an email, it kept on retrying, and I didn’t notice. The battery got drain in a matter of hours.
I noticed the mail application saying “1 message unsent”. I fixed my password, sent another message, which worked, but the “stuck” message stayed stuck.
I decided to delete the account completely. Fine, it’s gone!
NO!
Somehow, my Usage stats were EQUAL to my Standby time, and sometimes were not available at all. I could charge the phone, not use it for 2 hours, and it would say Usage = 2hours, Standby = 2 hours. It was obvious something was still trying to send in the background.
If you get a similar behavior ( Usage equal to standby ) , you might want to try doing a restore. That’s what fixed it for me, and it’s pretty straightfoward.
I hope the next firmware fixes that bug, because it could mean that anything else interrupting an outgoing message could drain your battery overnight. It should retry a few times, and prompt you..
