I have a POP email account set up for my business and I have turned off the push feature and set fetch for 15 minutes. My question is this......when I go to use my phone for whatever reason ( web surfing, phone call, text ) I always hit the wake / sleep button when I am done to turn the screen off. By doing that, it seems that fetching emails doesnt happen. Is that becasue I am putting the phone into a true sleep mode and it will only accept calls and text notifications??? I have experimented with sending myself emails and after 20 minutes, there is still no new mail until I actually go into the email boxes and then it connects and updates, showing the new mail in my in box. However, I just did another experimanet where I left the phone turn off on its own and in 15 minutes, my test email made the "ding" noise and showed up. I guess hitting the sleep / wake button blocks certain things from happening and only allows calls and texts ??
