So far not liking Lollipop on my nexus 4, wish I could roll it back to kit Kat. When I leave my home, Wifi shuts off . When I return, in order to turn Wifi back on I have to reboot the phone. What a PIA.
Found the problem. I had JuiceDefender Ultimate on my phone since I got it almost 2 years ago. Apparently it was "fighting" with the new 5.0 OS. I deleted JD, battery life is much better and zero problems with Wifi. Phone works great now. Love Lollipop.
