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!

THNX DAVIDCH , I DON'T WANNA BACKUP OR SYN MY IPHONE ,,,,,, BECAUSE I AM NEW IN APPLE IPHONE , I NEVER USED IT BEFORE, I HAVE NOKIA BEFORE 🙂 SO I WANNA ASK CAN I MAKE CHOICE OF SETUP AS NEW IPHONE ? ? ? ?AND IF THIS WHAT I HAVE TO DO IT AFTER THAT ? ? ? 🙂 THANKYOU FOR YOUR REPLY AND TIME 🙂
attaax,
after setting up the iPhone as a completely new phone (no transfer of previous backups, etc), a "reset-all settings" is probably not necessary, but certainly won't hurt either (you will just go back though those basic new user steps, but no added data will be deleted). either way, you still want to calibrate the battery to the software and, accordingly, will need to fully discharge and fully recharge. again, steps #1 and #2 are probably redudant in your situtation, but certainly won't hurt. you still want to follow steps #3, #4 and #5 with you new iPhone 4S.
good luck 😎
Yeah thats pretty normal. It actually most likely gets to 100% sometime during the night but by morning it drops back to 96-97%. Some say its due to the charge shutting down and not kicking back in until like 94% or so.
If you are not seeing this, i mean you never get to 100% at all, you may need to perform the battery calibration process to get it straight.
Also some say could be the same deal as posted here: http://support.apple.com/kb/TS1909

Anyone else have issue with battery at ~96% after a full night charge?
I charged overnight from 2% and this morning the battery icon shows full but only showing 96%?
Thanks in advance

Hello Davidch,
First of all I would really like to appreciate your commendable work on this forum. I got this IP4S last week and have been having battery issues since then, as everybody else on this thread. I have followed all your instructions step by step and have got this battery life. Below are a few screenshots for your observations --
Is this Battery Life Good or Bad ? BTW - I have switched off WiFi and Location Services including System Services like Location Aids, Traffic and Timezone. All this has been after a full charge yesterday. Is this something to worry about ? Should I go knocking the Apple Stores' doors for such kind of battery life ? I am frustrated by this. Never expected this from Apple at all :-( Please let me know your thoughts.
Thanks in advance.
if you have switch off wifi, you will default to 3G. wifi gets 50% better usage than 3G on avg (i.e. 9 hrs max vs 6 hrs max). it is best to use wifi, if it is available for data usage. according to spec and assuming you were using 3G for data usage on the last graphic. 11.18/200 -> 5.6% standy usage, 3.18/6 -> 53% data usage. 100-(5.6+53)=41%. your phone is saying 27% which is 14.4% less than expectation. i would try to run through my steps one more time. also, you may want to delete your mail accounts and recreate them on the phone. sometimes a corruption mail message/account can cause extra drain. good luck
My 4s worked great from the day it ame out until ~ 2 weeks ago when it updated to 5.0.1 and then i was having battery drain like crazy. I went to the apple store and was given the run around and was told some app was failing to completely close. I tried Davidch recommendations and saw a little Improvement but nothing like before. I went back to apple store again and the genius I met with really tried to help and ran diagnostics. He showed me how my usage and standby time we almost identical. He said it was likely one of two apps failing to close properly so I left each one open for 1 day each and left no apps open for a day ... Saw no difference in usage and standby times. Went back to apple store (good thing it is 1 block from work) and this time they took the phone in back and ran additional diagnostics and found a corruption in the system files. We had to run a complete reinstall and a new setup to restore phone back to original state. Pain to reinstall all apps and move then around again as well as resetting all settings I had changed. Using the cloud and Microsoft exchange made reinstalling everything else ok.
Phone is working great again.
Davidnc thanks for your help... All your posts really helped me figure things out and made me push apple store to fix my phone and not just blame it on apps not closing.
I am curious to see how soon 5.0.2 comes out...
Just wanted to give an update. I finally needed to charge my phone this afternoon. Final stats were ~7 hrs 47 mins of usage time and 2 days 20 hours of standby time. Please do keep in mind though that I never use 3G besides turning it on once a day to see if anyone sent me a photo message and I only turn on wifi when I need it then turn it back off immediately. Currently my phone is still sitting at 100% charge with 2 hours of standby time. For anyone having battery issues, if you are not attached to the data that is currently on your phone or can back up your pics/contacts/etc I would highly recommend doing a complete factory restore via iTunes, as it worked wonders for me.
Well its been one month now since my last reset. Below are my results. 12hours where spent on 3G while at work and in low signal areas(about1hr) airplane mode was used, which saved alot. I browse news sites, read articles for a hour, listen to music for a hour or two and made some calls totaling 30mins. How does this compare to apple specs davidch? Thanks for your help!
and a TIP for users who use SKPE..don't leave it signed in! it drain battery in stand by, it even does this on Android as well. Skype really needs to fix that. I think most folks here use Skype to some extend.

per spec and assuming you data usage was 50/50 wifi/3g. 31/200 -> 15.5% standby usage, 6.15/7.5 -> 82%. 100 - (82+15.5) = 97.5%. that shows you should have 2.5% left on estimate. even though you only have 1% that is really close and would consider it within spec.
Be patient guys. As of now I have installed ios 5.1 beta 3 and I am getting results I couldn't imagine that was possible on smartphones. I installed it and then did davidch method. And after the first decharge and overnight charging it is like this.
Settings for this are
- 3G off (there is a new button for iPhone 4S users in beta 3 where you can shut off 3G and stay on EDGE)
- raise to speak off
- system location only traffic everything else off
- diagnostics off
- iCloud push
- 3 gmail email on fetch every hour
- auto brightness and set on 20% now
- wifi constantly on
- BT is off
So I have around 20% each day with some light/moderate usage.
Hi,
just wanted to update on my own post. I took my phone (iphone 4s) back to the store. They will perform some tests on it to determine if there is anything wrong with the hardware.
I did this after talking to my carrier about high battery drainage and the "phantom usage" which was consistently about half of standby time even if I didn`t touch the phone. They asked me to check if the sim programs are working and they were not. They told me this was a known hardware issue with some iphone 4s. Apparently the connection between sim card and sim card reader is not working as it should and this could lead to both phantom usage and battery drain.
Well just wanted to let you know, this might be a problem for others as well. If interested I can update when I get the results.
(In the meantime I am using an old iphone 3gs and it gives me at least double the standby time 🙂 )

hey again i performed reset all setting yesterday night. i disabled time zone and iad, I waited until the wheel icon rotated and shut off after resetting. i pluged it into the charge overnight. Morning it was fully charged and showing 100%. Now the status is :
Uses 45mins
Standby 1 hour 25minutes
Batt per 91% remaining.
Is this okay or not???
need reply if you dont' mind
thankyou!
ok... if we assume that your data usage is evenly split between wifi/3g per spec, 1.42/200 -> 0.71 % battery usage, .75/7.5 -> 10%. 100- (.71+10) = 89.29% which suggest that you battery is ~2% better than spec 🙂
I suspect your iPhone is fine as far as hardware. You said this all started with iOS 5 which is very common with 3G, 4 and of course 4s. Some of the older apps are not playing nicely with iOS 5. You can try a restore and set up as new, then sync contacts and such with iTunes. Back it up first, Then see how it performs If its ok then you know it was an app. You can then install an app or two at a time. Also iOS 5.1 should be out soon and hopefully further addresses remaining battery issues. It would be a good time to remove apps you never use anyway and clean up things. Of course if you do that and it does not help, certainly restoring your backup wont make it any worse. I would guess a fresh firmware load will solve it for you,

Hey guys... So I'm finally posting after reading through all of the threads regarding this problem.
Ever since I upgraded my iPhone 4 to iOS 5 i had the Problem of massive standby drain and massive drain with normal usage.
After upgrading to ios 5.0.1 it eqven got worse and my ipad 2 also started to drain faster. (before i really had 10 hous of usage)
I tried to use davidch solution on my iphone several times and it didnt work.
On my ipad 2 it seemed to work ...
Now im thinking about that there might be a problem with my iphone 4. Problem is: my warranty has run out and i cant afford buying a new phone right now.
Do you think it makes sense to go to apple and hope that they offer me some deal for exchange of the phone? Even if im out of warranty?
prblem is: i think its a software thing.
Tried deleting email accounts, disabling push, disabling wifi....
I can WATCH the battery percentage go down.
Right now i have 66% left with 2:40 usage (some music, imessage, wifi on, bluetooth off, push on (just got 2 mails)) and 5 hours of standby.
I remember when i first got my iphone 4 i woke up, went to work and 4 hours later i still had 90% left.
Please help me analyze or troubleshoot that....
Regards from germany
Hi everyone,
apple gave me a new 4s. They concluded there was a hardware problem with the other one (would not tell exactly what). Phantom usage seems to be gone and sim programs are now working 🙂
Have not really tested battery yet but am still at 100 % after 1hour 40 min in standby.
I checked production date of the phone, it`s from december while the "bad" one was produced in october.
Might be some bad phones from early production?

That battery life is sort of normal if the drain is a result of the switching. Sprint network is not that good and as a result they roam on Verizon's network to keep you connected. Mainly in areas with no Sprint signal, which is mainly in doors and some parts of the US.
This happens on all their phones. Some show roaming and others Extended. If you don't want it to happen just goto General then Network then turn of Voice roaming. You won't connect any more and only stay on Sprints network. Anyway I recommend you try the settings reset following the steps in this thread. Then do a Network Reset.
Good Luck

Ok well leave it on then. Try turning off PUSH. Your phone might be drawing too much data. Also, download iAssitant and tell me the average idle cpu for 2mins. Only touch the phone to keep the screen on. Your cpu should be below 5% on avg.
Next, try Reset Network settings. Good luck.
Have you added a new app maybe? If so see if perhaps its causing your issue. Also you can try and reset network settings (even though you did the reset all) just to see if it helps. Its a know issue that something hangs and the network reset fixes it (as does iOS 5.1 so I hear). Guess you could try a restore and let iTunes backup,restore then restore the backup as it wants to and try. If that does not help a restore and setup as new may be warranted and let iTunes sync to get your apps and contacts etc back.
