Ok, I have to take back that this app produced my 'drastic' battery drain. I found out it was something else. It just so happened they occurred at the same time.
On the same day, and nearly the same time of day, I installed Spingtomize, our IT department took down our Exchange server. Even though I had turned off Push mail, I guess my Contacts and Calendar were still trying to communicate with our server. As soon as I deleted my Exchange work account, the battery drain went away. It's now been 6 hours since I took it off the charger and I still show 92% battery. Before deleting the account, my usage and standby times would be identical. Now I have completely different times, which it should have. The usage time is less than an hour, which is accurate.
My wife's 3Gs is connected to the same server and even though her usage and standby times are showing different, she told me her battery has not been good at all this week. I had to ask her since she rarely complains. I looked at her phone a few minutes ago and she's at 65%. She unplugged hers about the same time as I did.
Like I said before, I think the iPhone still tries to connect contacts and calendar even though Push Mail is turned off. When you kill the phone app, it comes right back on. And since my contacts are also in the phone app, I feel it just keep trying to connect to the server.
This may be something for others to look at when they get drastic battery drain issues. It's also another reason for me to get my contacts syncing with my Google account.
I can't say for sure Springtomize doesn't cause battery drain since I haven't installed it back on since resolving my battery problem.
BTW, special thanks to Ipheuria for helping me work through my issues. I really appreciate his patience and support.
