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!
Does this work for iPod Touch 4g? I just got a new one 2 weeks ago and i lose 20-25 percent in 1 hour!!! 😟 no background apps, brightness low, no email or icloud, no notifications etc. yet it still dies so fast D: So would this work for iPod Touch 4g?
Hello everybody,
My iphone 4s has already been 5.0.1 (9A406)
I did both reset all settings and network settings.
and i have fully discharged and charged overnight about 3 times.
This history below shows what i have done with my iphone 4s
Usage: 3hrs , 30 minutes : I opened Wifi about 2 hours for facebook app, but 3g always turn off.
Standby: 21hrs,51 minutes
Battery Life : 56%
I close all location service except Find my iPhone,
At the notification Center, I open Weather Widget, Phone,Messages,Calendar,Facebook,Reminders, Mail.
Anyway it doesn't use a lot of energy because I just opened wifi.
I just wonder is it okay for battery life in average?
About 3G, when i open it, every 2 minutes decreases 1% of battery.
Is it normal because it drains my battery so bad?
Thank you very much everyone. 🙂

Is it okay so far?
Thank you very much.

I am new to the apple old, I bought the iPhone 4s and I love it. I jut did the update on my phone and my fiancé's. I am hearing a lot about what to do after and what not to do. I did a fell restore of my phon and did the update. Is there anything else I should do?!
Hello David,
Months ago, I tried your procedure to improve battery life on my iPhone and it worked very well. Now that 5.1 is out, would appreciate your thoughts. From the last experience, I'm somewhat reluctant to upgrade without confirming that battery life isn't going to be an issue again.
Do you have any thoughts on whether battery life is an issue with 5.1?
Regards
Sanjay

Iforumuser, when you ResetNetworkSettngs, did you have to do anything other than resetting your WIFI passwords, or was that it? I'm going to do this too, but want to make sure there's nothing that I have to do other than enter my passwords again.

Thanks for your tips. Ive tried and noticed better battery drainage when I'm on wifi. However, when connected to 3G the battery still drain pretty quickly. Is that normal in your experience? Or should the drainage be the same? I've even turned off wifi to see if that was effecting the situation perhaps because the phone was hunting for wifi but it does not seem to be the difference. Any comments or suggestions would be appreciated.
Hello David.
I purchased my 4S back in November 2011 and was receiving great battery life such as the following:
at 11% battery
usage: 6 hours, 15 minutes
standby: 2 days, 14 hours
I updated to the 5.1 version after reading your post to 'sanjayfromtoronto'. Since the update, I have noticed significant difference in my battery life. I am not using my iPhone any differently since I purchased it-except for adding a couple of new apps which I rarely use.
Currently I am receiving stats like the following:
Now, when my phone is at 11% battery,
usage: 4 hours, 19 minutes
standby: 1 days, 13 hours
13% battery
usage: 3 hours, 37 min
standby: 1 day 18 hours
4% battery
usage: 4 hours, 1 min
standby: 2 days, 5 hours
I have employed your reset procedure SEVERAL times, but that does not seem to make a difference in battery performance?
Any suggestions?
Thanks.
I re-read your post again and something struck me that didn't before. During my resets, 'Location Services" were disabled, but the "System Services"- location based iAds and Time Zone were still ON" within Location Services.
Would this make a difference even though Location Services itself was disabled?
Thanks.
Hello ram130
I can't test that today. I have a significant amount of battery left before a complete drain, so you won't receive an accurate assessment of my battery performance.
That is probably better tested when I start with a full charge of 100% battery.
hello davidch, i've tried your suggestion to reset all settings, but it seems it doesn't change my phone battery life. i wanna ask you, how can you get 0.5-1% decrease per hour? do you have your celular data on?
my battery status is like following:
when no cellular data and no wifi : 0,5%-1%/hour
airplane mode : less than 0,5%/hour
when wifi on and cellular data off : 2-3%/hour
wifi off and cellular data on : 5-6%/hour
is it normal? i've tried this all in standby mode. I bought this phone feb28th with bundled xl (indonesia), at that time, even when my wifi off and cellular data on, it could last 1,5 days. then i change it into another provider (im3), here comes the trouble, it last only 20 hours of stand by time. so is this provider have something connection with my phone?
Regards,
Peter
Well guys...
I'm on 5.1
Tried the restore, set up as new iPhone, and every other trick.
Yesterday I charged to 100% before bed, turned off all apps,
And went into airplane mode... Unplugged and this morning:
72%!!!
Standby only
Ugh
So I just reset network setting.
If not better tomorrow morning, I'm going to genius bar.
Just got this 4s 2 months ago!
Used to be great!
Advice?
