AT&T's LTE 4G Network...Power Hog?
I am currently using a new iPhone 4s that was a replacement for another new iP4s that was exchanged because of horribly bad battery life. Well...this one is almost as bad, even after following every protocol I've found here and on other boards that claim to minimize and even cure the issue altogether. I even wasted my time on an app called "Carat" which tells you absolutely nothing at all except what apps are using the most juice...and that's something even a non-brain surgeon like me can figure out pretty much!
This phone, like the one before it, was loaded with the latest 5.1.1 OS update...and both were/are showing to be connected with AT&T's new LTE "4G" network. The iP4 & iP4s I have had in the past were both only connected with the "3G" network and both seemed to have at least twice the battery life these two "new" phones do.
So, is AT&T's new LTE "4G" network to blame? Is it, along with the latest 5.1.1 OS guilty of being the power hog, and not the phone itself?
I'd be interested to see how other AT&T iP4s users feel...as well as from some Verizon users as to how their providers LTE network is when it comes to battery life.

The iPhone 4S does not run on LTE. It runs on HSPA+ which AT&T is currently calling "4G". But HSPA+ is really just a newer faster 3G network type.
I believe it was with 5.1 that Apple added the "4G" network icon to the iPhone 4S for carriers to use on their HSPA+ networks. AT&T and Tmobile both do this currently.
On Verizon it also runs only on 3G.

I'd start going through my apps one at a time, maybe there is one that keeps updating or using data continuously throughout the day. Also, you might try and see if there is an app that will check your battery health. A friend's iPhone 4 had a bad battery and didn't make it to lunch.
I'm on Verizon, but my battery life is pretty good. I have 50% or more at the end of the day.

Also make sure that you close all unused apps as they can cause the battery to drain as well because they are still technically open just put in the back. Also make sure to not use the brightness level so high as that kills the battery quick as well.

Brightness, yes; the screens use a large amount of power. So put it as low as you can bare and use auto setting.

The CPU cores are actually pretty efficient...whether 1 or 2 cores. a dual core isn't that much more power hungry doing basic phone tasks. I think the second core even shuts off when the phone is idle.
The bigger power hog is the screen. If you can learn to live with a dim screen it'll go a long way to boost your battery life.
Of course, there are those rogue apps that continue to run while the phone is in sleep mode. But that's lesser of a culprit on iOS devices....but it can/does happen. Location based apps are hogs because they poll the GPS all the time. Another thought is on the 4s, you have Siri...that uses power as it's using OTA data. it can contribute to poor battery life if you're constantly using that too.

Well have you done in depth tests regaridng this so called battery issue? Because i know from expierence when you leave wifi on all day( and have enabled ask to join ) that can consume alot of battery life. That along with not shutting down apps that you use as well as a bunch of toher settings which we need to get first before making any sort of suggestion to you.What are men without knowledge?

I always keep "ask to join" networks turned off. I do keep my brightness at about 70% with auto turned on. Location services on.

Things to think about.
1. Do you have any apps using location services that you really don't need. This will drain a battery quickly.
2. Notifications. I had a major problem with te iP4 and Notifications. Every time something popped up it lights up the screen.
3. Service. We all know AT&T has spotty service at best and that is an issue for me. I have to use a M-Cell at work and I'm normally around -105 db at home so my battery goes quickly.
