I installed lollipop on my brand new LG G3 as soon as it came out. After all, it had to be an improvement or they wouldn't have created it, right? It totally ruined my phone! I could no longer talk over 20 minutes because it got so terribly hot that I couldn't hold it against my ear. Also, I always charge it to 100% at night before going to bed and it was always 98% to 100% in the morning. After the download, it dropped to 22% by morning. It was a total mess. I took it to the Verizon store and they gave me a brand new phone. I was so grateful to them. Now, I can't keep the system update from popping up so I go to the application manager (all) and delete the 'cache' first and then 'force stop.' It works for a few days and then the update keeps popping up again. My fear is that I am going to accidentally hit the 'install now' button. I wish there was a way to keep the system update from showing up completely. For now, I'll have to deal with it and be thankful that I got a new, perfectly working LG G3 from Verizon. My advice would be to forget lollipop. Believe me, and I'm a novice that can't do fancy things, so forget it and don't take a chance of ruining your phone.
