I don't believe the option to disable 3G data exists any more. Many (if not most) carriers are rapidly decomissioning their EDGE networks. You should not see excessive battery drain on 3G unless you are in an area where 3G coverage is marginal.
Where are you located and who is your carrier? In the US, AT&T has been notifying customers that the 2G (EDGE) network is being shut down for some time now.

Thank you, KiltedTim.
It's bad to read that!
Unfortunatelly that's not true. 3G drains battery very fast (or at least faster than 2G). LTE even worst.
I've already made my own tests. 2G is the perfect solution.
If 3G is turned on all the time my phone energy drops before 12 working hours :\
By the way, I'm located @Lisbon, Portugal and I'm using Vodafone carrier.

Where did you get the phone? It seems, doing some further digging, that the availability of this setting may be carrier specific.

Bought directly from Vodafone carrier. It's locked to Vodafone.
As you can see below, phone is spending about 10% battery/hour with 3G on which corresponds to the 12 hours (more or less) autonomy I wrote before. At last screenshot, I made LTE on just to show that there is no more buttons (LTE on or off).
By the way, BT is allways on too because of car hands free system. But BT is not the problem at all. The real problem is 3G (or higher) connection. It drains battery very fast.

That's the way it is on my AT&T locked iPhone as well. I keep bluetooth and WiFi on all the time. I wouldn't expect the battery drain to be that extreme in standby given the 3G signal you apparently have.
I'd suspect a rogue app sucking power or an Exchange e-mail account having issues communicating with the server.

I use Gmail account to aggregate all my email boxes. iPhone connects to Gmail using an exchange connection.
But this happens on my iPhone 4S too.
The problem is 3G, definitely. If I turn cellular connections off and use only WIFI, battery will be fine until the end of the day.
That's why I need 2G. 2G is lighter.
Thank you anyway

I agree with Tim, with 3 bars I seriously doubt that the 3G/LTE signal is your problem.
You had better check with Vodaphone. I would bet that they also plan to terminate their 2G network.

Well, I followed this tips lists:
Mainly I turned off push notifications and location services for most of the apps and turned off widgets (stocks, weather and facebook post widget).
Also, I'll start to kill some background apps after use like voip, music and navigation apps (it's seems there is some kind of exception regarding resources they can use when in background - http://hints.macworld.com/article.php?story=20130124092557493)
I usually do not kill any app since iOS is knew as one of the best OS managing background apps resources consumption. More, some recent OSs learn some of the iOS procedures to manage memory and other resources. But it seems there are exceptions, so I'll start to kill them.
This is an additional effort I would like to avoid, but it seems I can't.
btw, there is a way to have shell access to place some monitoring tasks on a NON jailbreaked iPhone?

Same Problem Swisscom...
< iOS 6.1 - Full Bar 2G
iOS 6.1.2 - 1 Bar 3G / LTE
No more 2G. On Business place cant create Audio Call !!

Hi kilted Tim
I have same problem as lascenso. How can I reset button of 3G instead of LTE. 3G drains battery of my iPhone 5s. I am Indian and there is no LTE network in almost area. So why this button appear. So please advise how to resest this.

The availability of the 3G toggle is at the discretion of your carrier. There is nothing you can to do make it rea-appear.
Currently Being ModeratedDec 5, 2013 9:24 AM (in response to lascenso)
KiltedTim is right!
Some time after new iPhone setup or iOS reinstall, carrier sends instrutions about LTE availability and/or capability and iOS acts in acordance by switching to 3G/LTE button instead of 2G/3G button.
Is a fact: this change occurs after carrier notification. Any way, iOS should have a way to use the 3 connection types as per user will. Everyone knows iPhone battery is a struggle issue (this is a problem common to every smartphone which have big displays and great CPU capabilities) and also everyone knows 3G and LTE modems drains battery. To send and receive ordinary emails while phone is in the pocket, 2G is more than enough.
Apple, think about it.

The reason carriers are disabling the 3G toggle is because they are shutting down their 2G networks entirely. Turning off 3G in that case would result in no service at all.

It makes sense in the future, KiltedTim.
At this point, that's not a common reality. There are lots of remote zones which only have GPRS/EDGE connection. I have a 4G/LTE data SIM in my car and 2G is not so uncommon while I'm traveling outside cities.
Any way, in my opinion, this is an iOS network settings interface limitation. There was not considered another button neither a 3 position button is available at all. If, and while resources are available, why not use them if user wants to?!
Same way, everything in the iOS was designed to have a permanent internet connection, from the scratch. They just don't care if user wants it or not!
Finally iOS 7 introduced a quick wi-fi on/off switch but not a quick carrier data traffic on/off switch as you can find in Android, for instance. I know this 'permanent internet connection' makes sense on modern smartphones but there are markets around the world where carrier data traffic is yet very very expensive. Even here in Europe there are countries where carrier data traffic is quite expensive! This should be an user option. Always.
Any way... I'm very happy with my iPhone, even as is!
