After getting the update yesterday evening on my Verizon 8X, I have had greatly increased battery life today. Right now at 5:15 p.m. I still have 83% battery left and my phone has been off the charger since 6:30 a.m. I have been at work today, as I am every week day, and my usage has been similar to most weekdays. (Moderate texting, a couple of calls, checking social media and emails a few times.) Normally I have around 65% battery at this time of day. So that is a big improvement! Not that it was bad to begin with. And I do think uninstalling the HTC app a few days ago made a small difference as well, but not this much!
Haven't had any rebooting issues either.
