yup. my nexus 4 battery was getting drained by something called mediaserver, and after a quick google search it was google now and google currents; which had absolutely ridiculous sync rates murdering my battery in a span of 2 hours. A thing to note is that when a significant portion of the CPU is being used on the nexus 4, the phone gets REALLY HOT. Untouchably hot. Leaving the phone in my pocket was actually burning my thigh.

mediaserver using a lot of battery can be caused by a corrupted media file. Wiping stored music / pictures often fixes that one. I've had that happen and tracked it down to a single small (empty?) file - once removed, the problem went away.

I don't store any music on my phone and I hardly have any pictures on it
