Bro, Seems like there is cell data been transferred when your phone is with screen off.
Awake (): 5 h 43 m 57 s (20637 s) Ratio: 94.5%
Screen On (): 1 h 12 m 49 s (4369 s) Ratio: 20.0%
This should ideally be equal, if you are not listening to music or downloading something with your screen off.
Do the following :
1. Remove the apps Social Hub with titanium backup
2. Uncheck Settings > Wifi Network > Mobile networks > USe packet data
3.Uncheck Location and security > a. USe wireless networks b. USe GPS satellites
and see if you are still getting the battery drain.
4. Uncheck Accounts ans sync > a.Background data b. Auto Sync
5. Goto market settings uncheck Google Admobile ads
Check if you are still getting the battery drains.
Hope this helps!

Just wipe cache and Dalvik cache from recovery and check if you are still having drain! If not try removing all the recently installed apps and check again.I believe one of the apps is trying to sync and keeping the phone awake.

Can i do that without a root?
Is there any chance it could be a hardware issue?

is it by any chance the new facebook app (looks more like the real facebook now?) I read quite many posts in regards to the partial wakelocks and the new facebook was one of them. The updated version is running a service that never lets the phone go to deep sleep. Search market for CPUspy (free) and it will show you what states your phone goes into for how long. Reset the stats before you go to sleep and wait overnight. Your phone should be around 90% or more in deep-sleep mode. If not, something does not let it go to deep sleep. I had the same problem, I'm currently running my phone for 1d6hrs with 50% of battery life still on it. I did a test and what I think based on BBS and CPUspy it was either the facebook app or SetCPU. During the night the phone was awake almost all the time along with the screen (even tho I was sleeping!). Another thing I noticed is that you have quite a high count on AlarmManager wakelock - that is a service used by many apps and that actually does not tell much unless you connect your phone to PC and extract the data from alarms. don't get confused, this is not your Alarm Clock, it's just a service that wakes up your phone at a scheduled time to check for updates. To check how long is the phone awake and difference after you've done some troubleshooting is under menu > more. It will show nice graphs.
In my case, my phone is rooted, running Criskelo v38, Siyah Kernel 2.6.7.. I uninstalled all app killers, stopped using FB app, switched off automated updates (checking if there are any updates from Market) and stopped using setCPU because Siyah 2.6.7 implemented new ondemand governor which merged ondemandX with lulzactive (not sure about the second governor now). Therefore all other governors became redundant. It sorted my problem with battery drain. Hope this helps a bit.
-EDIT-:
Sorry, Just noticed you already have CPUspy. Can you please submit a screenshot of the stats it's showing?
Btw i have the original battery with the original capacity of 1600 mAh
