For wakelock issue it is best to take a dump from bbs and bring it to the known battery drain thread.
Fyi, I get more than 20% diff in my battery life from my office (crappy coverage) even when I use less.

I have ZERO cell coverage at work, I mean none. I'd like to say I work in some top secret lingerie testing facility, but the reality is I work on the 30th floor, in a shielded data center behind building signage, no windows, etc.
It's a battery killer for sure, with the phone searching for service all day long, you either have to keep on a charger (uck), or go into airplane mode to have any battery at the end of the day. Half the time when at lunch or at home I'd still be in airplane mode because you forget sometimes.
We have secured wifi for vendors, since we don't allow them to physically connect to anything on site, so I built a tasker profile to turn on airplane mode anytime it detects that wifi/ssid. That way when I go to lunch, or leave for the day it automatically comes out of airplane mode when it doesn't see that wifi anymore. No more looking at the phone at 10pm and going WTF I'm still in ap mode lol...
