After installing the update make sure you reset all setttings. I have done a few updates now and have had much better sucess after settings reset all. Standby drain has been virtually eliminated from 2-4% hr before update. It is located in settings/reset//reset all settings. You loose some wifi and desktop settings, but data, apps, etc remain intact.

Hi all, just posting for some advice regarding a system restore.
It seems as though most people have had success after doing a system restore and setting up as a new phone (when I updates to 5.0.1 I needed to restore but chose iCloud backup instead). I am reluctant to lose too much info, so could someone advise me as to what kind of data would be lost a d what could be recovered from the cloud (not via restore but from my old phone)? I know things like apps and music would have to resynced but that's not a problem.
Thanks
Before doing a system restore, try the steps below. Corrupt system level settings created by an iOS 5 bug in the original release that caused battery recalibration issues, etc. Just installing the update does not fix the issue in most cases (sometime it initially can be worse). You need to clear out those settings and recalibate the battery. For those still having the "standby battery drain" issue follow the procedure below in order. It does fix the problem in most cases.
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose "setup as new phone" (don't worry your apps, data, contacts, mail photos, will still be there). At this point, Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

Guys,
Good News!!! In fact Great News!!
After I did the "Reset phone settings" --> Battery drain to NIL --> Recharge to FULL --> + 2-3 hours of more recharge, I am getting a significantly HIGH improvement.
Almost 7 hours now on STANDBY and battery still at 100% (can't believe it... 🙂 🙂)
Earlier it was draining like 20-25 % in 4 hours.
This is huge improvement!! I think my battery problem is solved. 🙂 🙂
Keeping fingers crossed for some more time now...so to check if the battery works normally with the Wifi, location services, and other stuff.
(iPhone 4S 64 GB iOS 5.0.1)
sounds great... enjoy you phone and have good weekend 😎
So Peter, you have tried the reset procedure described by Davidch? Other options I would recommend is resetting to default and not loading any 3rd party apps. See how the battery performs then. If better then there is likely some app you have killing it. Otherwise if it cant run with Apple default apps then there is a problem. Also I have read folks have had good results dong the DFU update. That is basically a firmware reflash. You can google that and see the procedure. May be worth a try before you go back to Apple for a replacement or refund.

Tottally agree about reset all settings - general - reset - reset all settings :) I did this and I can see my 4s stay on 100% for about 3 hours or more. What I did was disable all location services and Siri ( she's beta anyway ) and resign my wifi password, don't send diagnosis, turned all iCloud services off until the next update fixes the battery suck - it seems to me all the new additions make a great phone if it could actually perform without draining the battery - I know right why turn everything off, well it's all the same as if it was before iOS 5 in a way - a bit sad but all the location services and Siri's communication with iCloud seems to drain the phone fast - or I could be a couple of apps. Hope it helps.
glad it is working out for you. also, you should be able to comfortly run Siri and some of the other location/notification services... just don't let them get out of hand. the only one taking Siri away from me is my wife (she may be getting jealous). enjoy your iPhone 😎

I have now owned my iPhone 4S (my very first Apple purchase) since Thursday and I absolutely love it.
However, the battery drain does seem to be very quick, so I am trying your instructions David.
I did the settings > general >reset and then ran thru the setup questions.
now... in step 3 of your instructions that I printed out.. it says
"turn off system location services timezone and iAd"
I can't find those.... where are they?
susan... they are located in settings apps -> locations services -> system serivces (at very bottom)
thanks in advance and thank you for these instructions. Hopefully they will help keep my battery charged longer.
as a new Apple customer, this is obviously a new phone and am using it from a clean (factory) slate.. i.e. no upgrading from a previous iPhone or any "i device."
it certainly won't hurt anything. smart phones do use more battery than standard phone, but you should be able to get 1-2 days on one charge with moderate use (i.e. 1 day heavy, 2 days light). note, that my process typically solves the battery drain issue in standby. you can check your usage in settings -> general -> usage (at very bottom). also, when you received you iPhone was iOS 5.0.1 installed already or did you need to update it. just curious. thanks and good luck.
YES. I have had wifi sync on since day one just because its easier (well sorta of) I am still at the PC and starting iTunes. Anyway I was getting much better battery life since 5.0.1 and I have also completed Davids reset method since the 5.0.1 OTA update. So battery actually working pretty well. I do charge daily when i go to bed at night. Anyway yesterday I turned off wi-fi sync, I am still working on the same charge with 3.5 hours use and 1 day/4 hours standby and 33% remaining. Never even close to that before. Best ever was like 5 hr use and 22hr 22 min standby and 6% left over. So I would say definitely turning off wi-fi sync has helpd. Also I now notice wi-fi turns off when phones goes to standby now and comes back on then lock screen comes alive. I deduct its technically just as easy to just plug it in to sync since already as the computer to start iTunes.
I guess the real benefit is for those folks who leave the PC on all the time and iTunes open all the time, then when they go to bed and plug in phone it syncs. Otherwise no real benefit. I was sitting at PC and pressing the sync in itunes or from the menu option on the phone once in a while when i wanted it to sync. So just no cord haha so what right. But the phone was ALWAYS looking for iTunes the rest of the time apparently and draining battery unneccessarily. BTW I am backing up to iCloud automatically nightly anyway no daily sync for me needed anyway. So unless you have some compelling reason you HAVE to sync wireless, try turning that off and see if it helps you!
It does not. It keeps all data and apps intact. Other than entering your wi-fi there are a few others areas such as the who you are for Siri and email signatures seem to default back so those needs adding back typically. Mostly its all back once you run through the initial wizard.
You lose all your settings in the Settings app -- wallpaper setting, a changed font for notes, etc. But your data remains -- I still have all my text message history.
Here's the thing -- if you're worried, just use iTunes to make a backup of your iPhone before doing Reset All Settings. You can always restore that backup!
I stand corrected a little, if you have some other wall paper and such then it will most likely default it. But your apps will remain and if they are in groups they will also remain (mine did). I am using default wall papers so of course they stayed the same but also the icon order and groups I have setup stayed as well. And as Walter stated get a backup in iTunes or iCloud just to be safe. Good call there!

Oh another issue regarding the backup.
I think David did mention not to restore from itunes/icloud. Would that mean that I shouldn't actually use my old backup pre-update?
that is correct... after you perform the process and determine that your standby battery drain issue is resolved, it would be good to then perform a new backup to iTunes and/or iCloud. note that if you do need to return to older "pre-process" backup for some reason, just re-run my process and it should fix it again... 😉
That would almost be correct. As stated earlier there is no need for iTunes for this process.The phone itself asked you whether you wanted to set as new or restore yes? And you selected set up as new? Then walked through the wizard selecting the "out of box" options? If thats what you did then you are set. Once you have completed just let your phone run down until it cuts off with the spinning star. Then fully charge to 100% (pref overnight) but at lease a few hours after 100%. If you backed up already you have overwritten your backup you had before the process. I suspect you dont need it but its good to have a backup anytime you fool with the phones settings just to preserve your data in case something goes wrong.
Things are looking good !!!
I followed David's instructions yesterday, then I let the battery drain to 0% and the phone shut itself off, then I charged it overnight for over 9 hours.
At the moment, 5:08 p.m. east coast time, my usage shows:
usage: 1 our, 19 minutes
standby : 7 hours 44 minutes
battery at 72%
that's a huge improvement from what I was getting before.
I have Wifi and iCloud turned off.
Location services are on.
Siri is on.
Bluetooth is on.
Mail is set to fetch every 30 minutes.
I think that's it.
Clearly, I haven't used the phone a whole lot today, but before the reset the battery % was dropping 1 - 2% as I held the phone in my hand just watching it...
Thanks David !!! I think you have solved the problem.

your welcome and glad to hear it is working for you. it is kinda strange, but it almost seems like the phone was sick before and after the process breaks it's fever... lol. enjoy your new iPhone 😎
I would update to iOS 5.0.1, then perform the reset, then drain the battery all the way down til the star circles and the iPhone cuts off by itself. Then charge it back to 100% and leave it a few hours after it reaches 100% . Good luck with the update.
ram130, I have done so after your initial post regarding it. I have seen an improvement. Cant say for certain how much because the phone is used differently each day but the first day I did it I actually ran for 2 days before charging (low usasge ) but I have never gone to bed without putting it on the charger. So i thought I would try since I wanted to see just how long it would go. I was like at 57% and 1 day standby and 2 hr use after 1st day. Anyway I will say I have seen a definite improvement even if only slightly. The wifi cuts off now when the phone sleeps and you can see it fire up then you first get to your lock screen so maybe thats helping. I typically getting maybe 14-15 hours standby and 2-3 usage and have maybe 60-65% left.
Bottom line: if you can live without wi-fi sync and just plug it in I would definitely turn it off. I dont see it as that huge a benefit although it was cool at first 🙂
Excellent news! I assume you did the battery calibration as well? The entire process is required for optimal success. Also if you can do without wi-fi sync with iTunes, turn that off. You probably have to go to the machine anyway unless u leave iTunes open all the time. And set mail to manual. I mean unless you HAVE to have your mail sitting there waiting for you to look at, it makes since to just have it load when you open your mail application to actually read it. Its fast and that will further save your battery verses it downloading mail every x min. Lastly have some positive reports that 5.1 is helping too (of course some say no) but still hope yet.
