Default Nexus 4 Battery Drain?

I have a Nexus 4, I got it when it first came out and then the screen cracked. So, I got the screen replaced, but then got a battery problem - it would die around 50% and be at like 10% when I turn it back on. I got a new battery, put it in and the same thing is still happening.

It's completely stock. The Nexus 4 I'm using right now is completely fine running PAbeta though.

Does anyone know how to fix this?
