@marc-man Sorry for the late reply, I looked at the replies only by email. Yes, my serial number does start with DN.

Take a look at my latest post here: https://discussions.apple.com/thread/3491623?answerId=17259821022#17259821022 - might be of help to you as your problem sounds exactly like mine.

The post is very convincing and I am very satisfied by it. Unfortunately, I live in Dubai, United Arab Emirates and not in the US so I don't have an Apple store here but rather have official Apple resellers. I will try to talk with the company I bought my iPhone from to replace my phone but I'm not sure if they will actually replace it.

One more thing, I didn't have the battery drainage problem until about December 20 - bought it on November 8. I had perfect battery and in a 7 hour sleep, about 3-4% drained. I don't really know what has come up with my phone.

Do you still think I should replace my iPhone?

With the usage figures you report, It appears you may have a rogue task running. Did you get a SIM card from an older phone? If so, go to your service provider, and get a new one, then clear the phone settings, and try again. I find 13 hours of usage in 22 hours a bit more than is believeable.

Sorry to disabuse you of this notion, but NOT ALL USERS HAVE BATTERY ISSUES! Mine works just fine, and so do others, unless you believe that all the articles about the 4S written by various people over the world are just lies. I have read several that actually brag on their battery life compared to earlier phones they owned. ME for one.

Does that mean no one has battery issues? Certainly not. Some have pretty obivous hardware issues, and others seem to have 'rogue tasks' running that sap the battery and run up the 'usage' figures beyond reason. Others seem to have unreasonable expectations. If you are in the first two categories, you certainly deserve a fix, whether hardware, or software.

We are ll having these issues with the battery on iPhone 4s..

If this goes on to persist after we have done everything to save our battery life to pull least 8-12 hours..

Apple should take a call and conside replacing all our phones..

They are not cheap and the purpose of using the instrument for all purposes are not met..

Just using it as a phone is not the reason we bought them..

All the show of various things we could do is trully phenomenal..

We bought them for that..

But if the battery cant support this usage..

It is a total let down...

Its time for Apple to decide how they could go about making the right changes and decision..

Coz clearly, most iPhone users are not very pleased with spending this much money for a lost cause...

I can well imagine that if a user moves around on the fringe of usable 3G service, and his phone won't stay on 2G, but continues to search for a usable 3G signal, cranking up the transmitter all the time to reach a 3G tower, that forcing the phone to 2G would save appreciable battery power.

I just saw some reviews in german, they mention the 2G-3G toggle and also a stabilization of the drain, but not a "dramatical" improvement.

So, you have about 7 hours since full charge, and you have only used only 21% of the battery? I hope you realize that most users would consider that really wonderful. Projecting, you would need to recharge about 3PM tomorrow. Surely once a day recharging isn't too much effort.

I'll file this one under 'unreasonable expectations'.

I took out my iPhone 4S from the charger at about 8:20AM (my timing) and right now it is 3:40PM and I currently have 79%. I had 3 phone calls, one for 40 seconds, another for 59 seconds, and the third for 13 minutes, which results in a total of 14 minutes and 39 seconds call time. This is the only thing I did with my phone so I didn't open any apps and all apps are closed in the background. There is clearly a huge battery drainage problem with my iPhone and I tried about everything that says in this post.

@marc-man Do you still think I should replace my phone?

Thanks for dispelling some of the myths running around here.

One additonal point of information. Your iPhone is designed to make sure you can't deep discharge your battery, so it will shut down when it reaches a point about 20% above the deep discharge point. Note this is the same point used to maximize life of the Toyota Prius battery pack. The iPhone manual suggests the first full charge discharge (until the phone cuts off), cycle in order to calibrate the meter function.

Try this it workd for me

i faced the same situation but after searching over internet i'v found the solution to fix my battery life.

I hope this wil help you and every one who faces same battery drain issue
solution:
settings>general>date and time>set automatically>turned off. that's it.
set manually your location.

it solves the battery drain issue for me now i am 7hrs standby on 92% battery indicator.

form this video i got the solution

How to dramatically improve Iphone 4S Battery Life

Before December 20th, I had 3-4% battery drainage on standby in 7 hours during my sleep. You think 20% is good compared to 3-4% for 7 hours overnight? I guess not. Still think my battery is "great"?

I'd agree with you that losing 20% battery while phone is in Standby for 7 hours is unreasonable and I don't think your expectations are too high but no point getting upset by other users comments :-)

Have you tried a DFU restore yet? http://osxdaily.com/2010/06/24/iphone-dfu-mode-explained-and-how-to-enter-dfu-mo de-on-your-iphone/

I would advise you try that and set-up as 'new phone' before persuing a replacement.

You are rude, and your comments are not appreciated.

Perhaps something is now running that wasn't before. I probably should even suggest anyting to help you since you don't want help. Have fun.

Great. I will do the DFU restore once I am done with my mid-year exams and I will tell you how it goes. Thanks for being helpful. Greatly appreciate it.

Battery life is just pathetic. Have turned off everything. Done everything that has been suggested on this thread and still stuggle to make it 7 hours without having to charge it again.

rphunte42, I find your comments most of the time very unsensitive to the people's problems!

Your comments basically blames most of the time the people and very very few times the iPhone 4S!!! You just assume that people who have problems with the battery of iPhone 4S do not know how to use a phone and what to expect from a phone!

Again, rphunte42, this forum is not about how the people are using iPhone 4S!!!! This forum is about complains regarding the battery life of the iPhone 4S!!!! Here most of the people are comparing the battery life of:

1) iPhone 4S versus iPhone 4,

2) iPhone 4S versus iPhone 3GS,

3) iPhone 4S versus whatever-phone-you-want.

Rphunte42, this forum is not about telling to people who own an iPhone 4S that:

1) they have unreasonable expectations, and

2) their iPhone 4S has no battery life problem when they clearly state that they do have one, and

3) they play games on their iPhone 4s until it dies!

Are you RPHUNTE42 expecting or will you get any financial benefits or gifts from Apple in the future? (I have asked this question from you before but I got no answer)
