I think people explain it, is native sms keeps constantly running and won't let phone go to sleep cycle and it increasingly drains battery.1. Download Handcent or ChompSMS.
2. Set it up as you like.
3. Open stock htc messaging app, disable all notifications.
4. Close htc messaging app, and never open again.
It's a bug in the htc app. They have admitted, and fixed it. Waiting for carriers to distribute.
Oh, and also, you can uncheck to download media simultaneously with mms messages as well, and then as they come, download them manually.

Here is another thing I found out about android OS:
The reason android OS doesn't kill apps, is that is the way it allows multitasking. If app isn't used for a while, the OS will kill it...otherwise, when you tap homescreen from the app, the OS puts the app to sleep so it uses minimal resources. If system gets overloaded or memory runs low, the OS will kill apps automatically. This is nice! Also, please remember not to do battery pulls or hard resets, as that is same as doing a security wipe on a blackberry and will delete your information and all the apps that were loaded.
