I'm having the pictures disappear in message app also...battery was draining also..I think because something kept syncing..looked like Google back up.. I unchecked alot of unnecessary stuff....now phone isn't syncing as much...so battery life is better..I'm alitte upset theres bugs in this update.

I haven't had one single problem since I updated my phone. But I did not do it over the air. I went to the HTC.com/us and selected AT&T and Updated that way after downloading the file. Battery life is awesome!

I've done 2 factory resets and still have glitches. Mostly the contacts disappearing / reappearing in the messaging app. Another is that about every 3rd restart, the widgets on my home screens disappear and I have to re add them. Although I will say that after the first FR, my batt life has improved somewhat.
I am seeing better battery life with 4.3. I had a problem after the update with my music player (Beats as well as PowerAmp paid) playing each song twice. Turned out to be something in the way 4.3 uses the file tree. Checking my music folder only once solved this issue. 4.3 The only other issue that I have seen is with the proximity sensor. Last night I completed a call and when I moved the phone away from my face the screen would not come on. I had to push the power button at top of phone then end the call. But my next call worked fine. I had read that the proximity sensor issue is new with 4.3. Other than those two issues I am loving 4.3. And I certainly love my HTC One!
So I did a factory reset yesterday which resolved contact picture in msg issue. Also seeing an improvement in battery life..

After I first updated to 4.3 I had a battery drain issue. However, after doing a factory reset.
My battery life is much, much better than when I was on 4.1.2.
And my phone feels snappier.
