Have you tried the three steps? Reboot, if that doesn't help battery pull and if that doesn't do it, factory reset.

 

Just a thought, is there a way to revert back to the previous state before the update? I have a LG Esteem which they have found a way to go back to a previous version after doing an update. I have a friend with this particular phone(Incredible 2) and is having the same problem with battery life.

 

Something was stuck. It might have been a sync or an app.

 

I am having the EXACT same problems. BUT...now, my phone's screen is completely dark, the soft buttons on the bottom are lit but do not work. Oh...and it continuously restarts itself...all by itself. My phone was FINE before this HTC update last weekend. Going to Verizon after lunch. SO bummed!

 

Have you done a battery pull (take the battery out while the phone is on)?

Verizon will try to factory reset the phone by holding down the volume down button while turning on the phone. I forget what you have to choose to get to factory reset.

 

There is a menu option for factory reset. Go to settings... SD card and storage... factory reset will be at the bottom. Just be aware that anything stored on internal memory by the user will be wiped, essentially putting your phone back in "out of the box" state. So back up anything you want to save (like texts) on your computer. You will also have to reinstall your downloaded apps.

 

That only works if the phone can be turned on.
