Well, this battery drain issue is coming from iOS 6.1 to me and it seems that it is common on almost every iPhone model (4, 4S, 5, etc). I
After every iOS updates there is a group of users that report faster than normal battery drain, another group reporting slower than normal batter drain (longer battery life), and the vast majority of users that report no change in battery life.
As always, basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
Personally, I have experienced no detrimental affect to battery life from any of the recent iOS versions, if anything my battery life has increased slightly.

According to me, I've gone through reset, restore and even used an old version of my backups. Unfortunately none of them worked. This is a real issue, people are not just imagining things.

With hundreds of apps and tons of data in them, restoring my phone as new and not using my backup is a really painful option for me, even IF some of the apps have the sync option :(

Well, it's the only way to test it and know for sure. If you set it up as a new phone and the problem goes away, then there's something wrong in your backup. If the problem doesn't go away, then you have a hardware problem and it will need to be serviced.

I never said or implied that people were imagining decreases in battery life. What I implied and will state explicitly is that many users cannot be bothered to try basic troubleshooting to rule out a corrupt file or hardware issue.
If you cannot be bothered to try basic troubleshooting, why are any of us wasting our time here? You came here seeking advice, it was provided. Either utilize the advice or stop wasting everyone's time.

Thanks and sorry! But when everything is OK and your phone battery lasts up to 6 days or more on standby and suddenly after an update, its battery begins to drain fast and many people report just the same problem after the same update, why should us look for the issue in our backups? I even restored one of my 3 months old backups to be sure it is not affected by my recent apps or settings and even go through "Reset All Settings", none of them worked. Other people even set their phone as new and report no change. If you where in my place, what would you do?
I appreciate your advice and thank you very much for your time and attention.

Regardless of what othe people have done, if you don't at least try setting it up as a new phone, then you can't fully test it. If you do set it up as new and it still does it, then take it in for service.
If you're not willing to do so, then go look for help elsewhere. You're wasting our time.

This is my recent test:
I charged the phone to 100%, unplugged it and set the Airplane Mode to ON and guess what? It is 11 hours now and the battery is still on 100% of charge!
I am using 2G network and the signal in my area is very good (full antenna). Maybe the problem is in communicating with the BTS towers and nothing related to apps or settings or hardware.
It is obvious that the Airplane Mode saves battery, but maybe in recent iOS updates, it is the 2G network connection that drains the battery more than usual.
What do you think?

I have good news and bad news. The good news is that my phone stopped fast battery draining! The bad news, I don’t know how or why!?
In the previous days and after upgrading to iOS 6.1 and then 6.1.2, my battery was draining about 3% every hour on standby. I did many tests from restart, reset and restore to deleting and adding mail accounts and so on, none of them worked.
Last night I left my phone on the table with 87% of charge. Next morning I was expecting less than 60% of battery, but it was on 84% after more than 8 hours!
To me, it is back to normal and I really don’t know how. I absolutely did nothing special. I hope this happens sooner or later to others with battery drain issue.
