Just a follow up.
1st Step: I deleted my iCloud email account
2nd: I turned off all the details on my other email accounts. (As mentioned at page 1)
3rd: Hard Reset (Holding home button + switch)
4th: Turn on. (While crossing fingers)
Worked for me, for at least 10 minutes now.
Still trying to observe if there will be a drop.
Note that I don't have an exchange account and I'm using iPhone 4S.
I hope this helps.

A sudden 3 percent drop without doing anything. :( back to the drawing board!
Which is meaningless. When you turn iCloud back on it must resync everything, which of course will require battery. If you still have excessive battery drain after an hour you have a problem. But 3% doesn't tell you anything.

The iPhone has a small battery in it, try not to overcharge the battery I have read some leave there iPhone charging overnight that is not good you with destroy your battery that way. You should only charge the battery to a 100 percent in drain to 0 percent once a month. The battery are design to hold a charge at 80 percent. You only get a 1000 cycles on drain and 100 percent over the battery lifespan.
Totally bogus; you are making this stuff up. I have no idea where you got 1000 cycles when Apple says 400 cycles. From http://www.apple.com/batteries/iphone.html:
A properly maintained iPhone battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
Note that this also says:
Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
It says at least once a month, not no more than once a month.
You cannot overcharge the battery; the phone won't let you. There's a smart charger in the iPhone that stops charging when the battery reaches 100%. In fact, occassionally after charging overnight you will see the battery at less than 100%; that's because the charging stopped at 100%, something used power, and the charger doesn't come back on until the phone reaches 96%. You also cannot totally discharge the battery; the phone shuts off before the battery is fully discharged.
I've charged all of my iPhones overnight, every night, for almost 6 years. I currently have a 3GS that is 3 years old and its battery is just fine. My 4S is also fine after 18 months of use.

I see you are doing your homework. See the infomation is out there Apple tells you how to properly maintain your battery. All some people have to do is go to Apple.com or google it and you will find what you are looking for.

I have a 4S on Verizon and immediately after upgrade to 6.1.3 I started experiencing the rapid battery drain. Nothing else changed on my phone so I do completely attribute this to the 6.1.3 update. I went from a battery life at least 1 day to less than 6 hours of battery life overnight. This went on until I found this and other threads.
I did not have iCloud running but decided to delete that account since I wasnt using it and saw commentary about in other threads. I deleted my exchange account and did the power cycle of the device then added the account back in. I also turned off the auto-push and now only do manual checks.
My battery consumption now seems to be back to normal.
Thanks for the suggestions. I hope the rest of you find a solution that works as well.
