    You are right about quoting the specs - but the spec itself is misleading. The reason for this is that I believe that the 0.5% per hour standby drain goes on on top of everything else you might be doing. That's the first thing. Then the second thing is that "background processing such as email auto-checking" counts towards "usage" - and of course this happens concurently with everything else. And varying conditions will affect background processing. So in the end, you can never fully isolate the spec components like you did. For instance you might be browsing the web for some hours on 3G but at the same time you will lose 0.5% per hour and you will lose whatever background processing is happening also. Which is why people here trim down many options - especially network centric ones. And then I've seen them get close to spec. A common spec is 5-6hrs of mixed web/call use for 22 hrs of standby. As I've said a long time ago, an Apple day is about 30hrs.

     

    Good luck!

    I am also suspecting it is hardware issue because my 4 with 5.01 is fine.

    It's kind of funny, since if you did a search for my name, you would find me under Apple Haters.  I have never liked Apple, as a company, but decided to buy the 4S because of experience with my wife's 3GS, and the iPhone 4 I used for a month (long story).  It is simply head and shoulders above anything else in the market.  I very carefully researched, for 6 months, the various smartphones that had the features I wanted, and it came down to the 4S or the Galaxy S II.  The 4S won out because Android phones often don't get updates to their OS, and I had used a Windows phone for 2 years with NO updates.  Compared with that, Apple's updates are fantastic. 

    I am not anti-consumer, but I see little benefit in attacking a company you want to help you.  Warranties are pretty much local things, so what applies here may not apply where you are.  My 30 day free return point ended 2 days ago, and I never once considered returning it.

    I'm sorry some people have battery issues, and I'm sorry some people expect too much of the phone.  I anticipated that the phone would use more battery power than the 4, but after turning off the things I didn't want, or need, and installing 5.01, I have very good battery life.  At some point, I am pretty sure that Apple will announce what they have found relative to battery issues, and I expect those to be multiple causes.  I hope they can be corrected via software, but who knows.  They WON'T be corrected by legal action, but by talented technologists.

    I found that battery life on any cell phone or smartphone will depend on the usage and how the user has it set up. My iPhone 4S battery has lasted me 2.5 days without charging and was down to 1/4 charge by then. That's pretty good battery life. I recommend (if you want to extend battery life) disable location features, auto-checking of email, and either turn off iCloud or just have one item in it activated, such as documents or something. I prefer to sync directly to my mac then having something stored or transfered from and outside source. I hope this helps. Good luck!

     

    Are you on Verizon?

    Yes.  I have done that.  After the 4 I had been replaced by my 4S, I still had it for a few days, and anything that didnt require cell phone service still worked.  Presumably, it would also still be possible to use it contact emergency services (911 in the US).

    Fair enough! Although I consider sometimes legal can put pressure on technology. We will see I guess!

     

    Take care!

    Update on my battery issue...

     

    Following advice on doing a factory reset and starting from scratch, I did just that !  DIDN'T install a backup but downloaded the app's I needed from i-Tunes (and didn't dl a load I don't use), re-configured mails and other data the hard way.

     

    I've turned off the System location things that aren't necessary.

     

    Charged to 100% this morning and 14h10m later, after 3h37 of heavy use (watched 20min of a TV programme in the deal !) the battery indicates 30% remaining.

     

    That means with less intensive (more normal) use, it would now give me 1.5 to 2 days before needing a charge.

     

    It also is no longer indicating that I'm using it when I'm not !

     

    Perfectly acceptable.

     

    So it appears the reloading from a backup may well be the cause ?

     

    Just hope it lasts

    Cyberman04- How the heck are you getting that good of battery life? I was at 59% battery with 3 hours 47 minutes of usage & 10 hours 48 minutes of standby

    You make a good point about never fully isolating the spec components when assessing your usage as compared to the apple specs.

     

    The common spec you listed is about what I'm getting for battery life and I'm happy with it. But I did have battery issues before doing a reset...

     

    My first iPhone had a problem with the camera autofocus not working, but the battery was just fine. I went to the apple store and they gave me a brand new one due to the camera problem because I was within 30 days of purchase.

     

    Immediately I noticed that the new one drained much more quickly and lost significant battery life while on standby mode. I tried deleting my mail accounts, resetting network settings, etc. and nothing worked. Finally, I decided to download the newer build version of 5.0.1 (9A406) -- released in mid December -- which might not have been what fixed my phone, but what was essential is that I did a complete reset and erased all content from my phone. After erasing and reseting everything I synced with iTunes but made sure not restore from a previous backup, i.e., I set it up as a new phone.

     

    I'm not sure if it's true, but I read on various blogs that in some cases doing a restore from a previous backup creates some corrupt files that can drain battery rapidly. By setting it up as a new phone this is avoided. I this is in fact true, I wonder why it only happens to some users...

    I agree with this summary 100%.  In many cases, specs are used as a marketing tool and Apple (and all cell phone mfrs) will present the specs in the most positive manner possible.  I estimate that I can get roughly 6 to 6-1/2 days of stand-by if I don't touch the phone (with the settings in my last post).  That is approximately 80% of the published specs which is reasonable to me.

    Ha ha ha...As I had posted a while back: I disabled a lot of features, especially the auto-checking of email and some location services. I only enable features when I need to use them. For instance: I went to the Apple Store at a mall today to purchase an item. I used Apple's new purchasing app in acquiring the product. So, to do this, I activated wi/fi and the location services for the Apple Store app. Performed my purchase. Then when finished, I disabled wi/fi and turned off location services for the Apple Store app. <Grin>

    That's an interesting story but my experience is totally different. I've had my 4S for about 4 weeks during which its battery performed exactly like the battery of my previous iPhone 4. The night before yesterday I switched to iCloud. Yesterday in the afternoon I wanted to use Siri but she failed, could not connect to the server maybe. Shortly after that the battery drainage started. If you would have witnessed the difference between the day before yesterday and yesterday you would not believe that it's a hardware issue. Drainage went from about 1% per 10 minutes up to 1% per 1-2 minutes. That is five to ten times the drainage that it had before!!

     

    Today I turned Siri off and the drainage became a bit better. Late in the afternoon it started to become worse again. I turned all iCould service off and drainage went down from 1% in 1-2 minutes to 1-2% in 10 minutes. I switched mail in iCloud back on, no impact on battery. I continued to switch service by service back on until I reached calendar. After that it seems that the drainage becomes worse.

     

    My issue seems definitely software related (iCloud, Siri).
