I am on AT&T ver 5.01 and there are a few things I like and several annoying features. The Smart Unlock feature works fairly well for me at home. I had to include a couple of neighbor's address to get it to work. It would not work with just my home address. And, sometimes it will still lock the screen (not often). I haven't tried the Bluetooth Smart Unlock feature.
I really like the lock screen notifications, but I don't like the way they are implemented. First, you only get two notifications at most to show. If there are more than two, a little bar appears at the bottom that you expand. That takes you to your home screen where all the notifications will appear. But first, you have to swipe on the lock screen to get past it. It's not locked, but you still need to swipe. The lock screen gets this gray box to indicate it. Why can't it just go directly to the app or home screen when you swipe or pull down a lock screen notification?
I also hate the fixed placement of the lock screen notifications. They always appear at the top of the lock screen. And they always shrink the lock screen clock down to a small size? Why is that? I like the large clock and want to see it at that size at all times. The other bad thing for me is they took the weather forecast off my lock screen. I always looked at that and now it's gone. These things should be user configurable settings. They have made the lock screen less flexible.
Another annoyance for me is the Comcast Xfinity email app. I have notifications turned on and each new email sound is a short beep. On Lollipop, the notification sound for this app often stutters. Instead of one short beep, it will beep like a little machine gun - beep,beep,beep,beep,beep, etc. Very annoying.
My heart rate sensor lit comes on all day when something touches it. I have to turn my phone around in my pocket so other people can't see the red light shining through my pants. I use Google Fit and have no plans to delete it. It always worked fine before Lollipop.
AT&T has placed their logo permanently in the status bar. It's the first item on the top left. Why? I didn't have that before.
My battery life is worse, without a doubt. I tries the clear cache, the battery pull but not a complete reset. That is way time consuming to set the phone back up the way I like it. And it doesn't necessarily fix any of the issues I have according to what others say here.
I wish I could get my issues addressed. I read that it is unlikely that we will get Lollipop 5.1 anytime soon, if ever. Except for the Smart Unlock feature, I kind of wish I stayed with Kit Kat. My phone was stable then and i could have used an app to get Lock Screen notifications with a lot more flexible settings.

I forgot to mention the crappy Do Not Disturb changes. Now, my LED light shines all night even though the phone is supposedly in Blocking Mode. What is up with that? It worked really great before.
