I don't really know what you mean by using no apps, but this is my configuration and use as for today:
Iphone 4S iOS 5.0.1 (9A406)
Notifications on for buit-in apps + gmail and facebook (each hour)
Localization services off for time-zone, siri, iAds, network search and all other system services
lightness on auto and low.
siri on with raise to speak off
no iCloud account
no mail, contacts or calendar push
ping and itunes off (on restrictions)
and I got 5 hours of really light use (one phone call, two checks on gmail and facebook, couple of minutes playing and two photos taken)
15 hours on stand by
that was over the night.
during the day today I made a full charge and after 2 hours of moderate use (gmail, and 10 - 20 minutes playing) I got 58%
is that using lots of apps?
I just swa in comments at this article (http://9to5mac.com/2011/10/28/apple-engineers-contact-iphone-4s-user-to-diagnose -battery-issues/#more-103389) two people saying they went to a genius bar or apple store and that they found a problem with safari and locations, and once the app was deleted and reintalled problem was solved.
I wonder if I can get some help in an iPlace, since there's no apple store in Brazil.
It amazes me how many people on here are taking up for Apple like they are drugged by the great Apple pill. There are tens of thousand of people across the country having problems with these phones. First it was the antenna in the 4 now the 4s with more holes in it than Swiss cheese. Why would anyone want to work on a phone they paid this much for. Turn all the stuff off to use it BS I can get a free phone that will last longer than the Iphone and get days out of the battery. I have a few 4's that we use at work and I mean use all day long , don't get out very well but the batteries will last 3 days with constant use. I went to the ATT store at the mall today to look at other phones since its evident Apple is not going to work on the battery and noise issues and they had boxes of I phones people have returned due to the same issues, all had them less than 30 days and returned them. If Apple cared they would be on here offering help, exchanges, money back whatever. Oh you have the Apple trolls on here and the people who think they are Apple engineers raving about how great they are just don use them and turn everything off. No one will convince me that Apple is working on this , with their recourses ,engineers, etc if there was a fix it would be in by now. Faulty batteries and components period So now off to work on the 5 scrap the 4s=scrap phone and make more money off the hordes of Apple worshipers.
Sigh for the firstg time in 7 years of being a loyal apple fan, apple is starting to get on my freaken Bananas!!!
So I was again, just in case I was doing something wrong or forgetting something, I Install the 9A406 build, reset all factory setting and go through the tedious steps to help save my battery life on my pathetic new phone.
Next thing you know, I want to install my whatsapp, and boom Whatsapp is off all the AppStores (and some rumours say that Apple dont want it there and they want to force users to start using iMsg!! So there goes a great platform for my only real good communication to my friends who own BB and Android. Funny part is that I WILL NOT be convincing them to get Apples, and may just drop this phone face firt on the ground, burn it, let insurance pay out and get a droid!
I posted a very thorough explination for this problem. I hope my post helps!!! Let me know!!!
Restoring to new and reinstalling the full iOS is nothing new and there is no witchcraft there. This was suggested hundreds of pages ago literally. It is clear that some users have some data in their restore which creates issues with iOS 5.0+. For many reasons. This was the case with this guy having a single corrupted video file in his library for instance, or of this other guy using an unusual field for a contact and passing that contact along many mail client iterations etc. Unfortunately, some people have a terrible battery life even with a full restore to new + iOS with no apps and basically everything off. Worst is that they might restore to new, have some peace of mind for some time, then have issues pop up again. The reason for this is that there are most likely many problems with iOS 5... there is even most likely variations within the problem causes for a single set of symptoms etc - problems within problems within problems. The "data sanity" issue is clearly a vector.
But since you kissed your iPhone and loved it maybe you won't have issues no more
try to do the followings steps, those helps me to save the battery. Try it.
Make the new firmware 5.0.1 9A406 to your 4S if needed.
1. Go to Settiings / General / Siri / turn off Raise to speak and then reboot.
(A sensor upper the earphone is continuing on even if you turn it off, YOU MUST REBOOT YOUR IPHONE AFTER THAT.)
I think that it is the major problem about battery drain.
2. Go to Settings / Location Services / System Services / Turn off Setting Time Zone
3. Go to Settings / Notifications / Turn off Calendar, weather, stock or move them to Not in Notification Center
(calendar may be not need but I don't use this function, so I turn it off.) (Weather and stock always runs GPS or internet to update the states.)
4. Click weather and turn off local weather. Set your area in the weather list. If using local weather, it always run the GPS.
It is not very important. Contrary to what you think you may have one or a series of issues or no issues at all (first of all what makes you think you have a battery issues? Do you know the specs - if one gets 5-7 hours of mixed use with 22hrs of standby, he's pretty much on spec - it's not the advertised spec maybe, but it's those numbers that come out here - people having 2-3 days battery life are featherweight light users i.e. 1hour or less a day). There is no one set of things that works for everyone, despite what some would have you believe. So it's more about method (and ultimately refund if you get fed up or if sanity becomes an issue). The high level UI way is how this thread started, along the lines of http://www.apple.com/batteries/iphone.html and ultimately this https://discussions.apple.com/thread/3526981 . You can try those or even try to turn off everything that has an "off" switch in your settings panel and see what gives. You can put your phone in airplane mode and use it as an expensive iPod and see what gives. At the other end of the spectrum, you have the lower level stuff, like restoring to new and data sanity. You can restore to new and reinstall iOS and see what gives. Then you can add apps one at a time and see how this affects your battery. If you have mail you can remove and add again your accounts and such as removing and adding stuff again helps in some cases. In some other cases, people had weird SIM issues and had better results with the 5.0.1 version that was geared towards sim issues (http://support.apple.com/kb/TS4148). Finally you may have one piece of data that poorly syncs or restores badly due to corruption for instance. Welcome to the high maintenance world of iOS 5+ where some users soft reset their devices every day before going to bed to kill rogue processes and such for example. Another solution is to wait and pray for an update that would fix by chance your issue. Some have lost their faith.
Welcome and good luck!
