The date announced earlier for the OTA update was the 3rd of November but the Nexus device owners are still waiting for the update.
There are some reports that the Android 5.0 Lollipop update showed some bugs which has to be get fixed before the update roll out for the Nexus devices. The issue reported was the drainage of battery while the WiFi is ON and this was really critical as some experimental devices shown a decrease of 60-70% of the battery with in 2-3 hours of internet usage on WiFi.
In some cases there are reports that the devices have experienced fully charged to 0% battery in 4-5 hours of usage. This entry is actually a catch-all of sorts that is supposed to account for the difference between observed and computed battery drain.
