I received the Sprint lollipop update on Sunday, July 19, 2015, and have noticed some improvements. Most notably the quick battery drain while using a Bluetooth device appears to be fixed. I also had to update Waze and a number of apps as they no longer worked correctly after a reboot from this update. I immediately updated my apps by going to the Google Play Store, and they are all functioning properly again. My Note 4 is running much smoother and less laggy. This update has cured some issues and should be updated immediately.
