I myself use friendstream, but both FB and Twitter only check for updates every 2 hours. I use the home clock / weather widget with refresh every three hours. I use the full page agenda as it is my WORK phone. I have Exchange PUSH email enabled as if I don't use push my company will force a BB on me. I've not complained much about the phone's battery life except to say that I used my OC'd (to 1000MHz) the same way I use the TB but I averaged over 20 hours on the D1 vs 4-5ish on the TB.
Now what DOES tick me off is the fact last week I went to the VZW store in the hopes of getting a big discount on the extended battery by complaining about the battery life. The woman who sold me the phone was working to figure out what they could do when some salesguy came over to help looked at my phone for a couple minutes and then said it should be better now.
He set the screen brightness to 10%. Yeah, 10%. Yeah, without asking.
He installed startup monitor on me without asking and disabled the VZW junk apps that he could.
He installed advanced task killer without asking and set it to aggressive.
He did something to SMS as all of a sudden I don't get about half the messages being sent to me and I did before.
And finally this morning I got a call at home from my boss asking me why I have't been responding to e-mails. I said I hadn't received any. Well sure enough it turns out the "helpful" sales guy set my Exchange PUSH e-mail to poll every 2 hours instead. Yes also without asking.
I don't know yet what else he changed, but I have to run back to the store to speak with the manager as this is totally unacceptable behaviour from a salesperson.
