Yeah most of the solutions to N5 battery drain have always pointed to poor coverage. However, when I travel for business and spend a week in a metro area with 5 bar signal I experience similar battery life. And putting my phone in airplane mode and using wi-fi calling does not help either. So, I'm not really sure what the deal with my N5 is. I've had it for 2 years. May need to do the upgrade to the N8.
