Default Wakelocks and Massive battery drain!

Hi guys,
After updating from a March nightly to the latest Cyanogenmod nightly I've been experiencing the worst batterylife I have ever had!
I mean, seriously. Charge it up at night, place it by my bed and it's completely dead in the morning!
So it loses 100% battery overnight, with no usage whatsoever

I've tried beanstalk (Also Cyanogenmod based) and experienced the exact same issue. A full wipe and a brand new Cyanogenmod update and it's exactly the same.
I really can't return to stock as I'm making use of a lot of Cyanogenmods features.

The wakelocks are:
As reported by BetterBatteryStats:

Msm_hsic_host
And also a msm_camera wakelock poped up at the top of the list once.

Needless to say "Android OS" tops my battery usage screen with over 90% usage
Is anyone else experiencing the same issues? Anyone know a fix?
I'm basically without a phone right now

I've got the same issue here, but for me it's caused by Google services. At times my battery drains within 4 hours, even if I don't use the phone.
But at some times (most of the times) the phone just acts normal.
Before 4.3 I never had this problem, waiting for 4.4, hope that my problem will be gone. Else I'll just go back to 4.2

Aha! Success!

I have found the issue, I'll post it here if anyone else is having the same issue. Not sure if it'll help you though Dsteppa as your problem seems slightly different to mine
Although I would recommend "freezing" google maps as a starting point. See if that helps! Many android devices suffer from a similar problem, chances of it helping you is about 70%. If you're rooted it's relatively easy to do using apps from the playstore

Msm_hsic_host is used to "mount" the 3g modem as a usb device.. At least that's what I've gathered from various sources. Some phones have a kernel issue which stops the modem from being "unmounted" when data sending/receiving has been completely and thus drains the battery.

Turns out Msm_hsic_host was working as intended. It was actually an app which was apparently steaming data in real time, forcing the 3g modem to remain at full power and preventing the phone from sleeping. The unusual thing is that this app claimed it only consumed less than 3% and didn't even show on Better Battery Stats!

Uninstalling the app instantly solved my battery power issues! So for anyone experiencing similar issues, check for any apps which could be using "realtime" streaming; Such as third party Twitter / Facebook or even Email apps.

Hope this helps!
