I have a Nexus 4, fully updated and have noticed a few times in the last few months (so, not a common occurrence), that my fully charged battery is going down very quickly
Opening up the battery monitor, it tells me that the "phone" app is keeping the CPU awake - today the phone had been off battery for 3 hours and the keep awake was just over 2 hours, taking the battery from 100% to 65% in those 3 hours.

Obviously the phone app part of the phone is a system process and can't be uninstalled as I would with some other rouge app that may be eating the battery

Anyone have any ideas?
