I also experienced battery life cut in half after ota update and I couldn't select my ADW EX launcher as default anymore. I fixed the launcher by reinstalling and and getting a home switcher app and clearing the default launcher setting. With that said, I tried installing juice defender to manage battery better but phone was still dead after 5-6hrs on battery (yes, it was getting hot but it didn't feel to the extreme some of your are discussing).
I was holding out for the 30 day return period before rooting the phone, but since the battery was so pathetic, and people who had rooted and were running custom roms, didn't have this battery problem, I decided to start down that path. I got as far as using the HTC process to unlock the phone, at which point I was forced to to a factory reset. It got too late that night and I decided to complete the rooting later. 3 days later, I still haven't rooted it because i had other emergencies (house furnace is almost dead), but I'm SO EXCITED to report that since doing this factory reset, my battery life has skyrocketed back to normal, maybe even better then it was originally! I can easily unplug in the morning around 9AM and WITHOUT recharging it still had 36% battery last night around midnight. All 3 of the location services on my phone are enabled. 4G and wifi used throughout the day, had about 4 phone calls, checked facebook once, checked gmail a few times, did 2 web searches and texted throughout the day as needed.
So, if you're outside your return period and you loved your rezound before the ota update, it may not be the most desired thing to do, but if you factory reset your phone, you can get the good battery life back again!
By the way - when i look at my battery info - verizon location agent isn't running at all...
So that's my experience. Let me know if you have any questions.
