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!
basbalcoch... "reset all settings" does not delete any of you data (i.e. contacts, mail, pictures, etc). it only sets your basic system level settings back to the default (i.e. wallpaper, screen bightness, network, etc). again, all you data should remain as is... good luck!

Hi David
I have the exact same problem with my 4S and would like to try your work around.
But now my question: If I do a complete reset choosing "new phone" in setup, what will iTunes then do when I connect the phone and there is still my "old" phone registered?
Thanks a lot for your answer.
Marcus
marcus,
choosing "setup as new phone" after doing a "reset all settings" does not exactly set it up as a completely new phone (which i agree is a little confusing). it merely sets the basic settings back to default. this inlcudes wallpaper, brightness level, network settings, etc. it should still connect to your iTunes as it did before...

My battery life went down noticeably after I updated to IOS 5.1 also.
Here what worked for me:
After reading other users suggestions in this Thread and others, I decided to do the easiest first.
I went into >Settings >General >Reset >ResetNetwork Settings
I had to reconnect my Wifi but other than that it was simple and so far battery life has improved.
If that had not work I would have tried the Reset All Setting next as mention earlier in this Thread.
As standard practice I always let my battery drain down once to about 10% each month and fully recharge.
Yes battery life improved so far but I haven't used it that long yet.
I noticed after the IOS 5.1 update that my phone would lose at least 20% of the battery life overnight doing nothing and connected to my home wifi. I reset the Network setting last night, charged the phone to 100% before going to bed and it was still at 99% battery this morning which is what it used to be.
I'm down to 80% today but have used 3g and wifi data and a couple apps this morning. Time will tell if this fixed it completely but it was quick and easy to do.
I reset the settings in my iPhone 4S and it's working perfectly now! 😎
Previously the battery would only last a few hours, but now it can last days at a time!
I used "Reset All Settings" and "Reset Network Settings". I did not "Erase All Content and Settings". I did not need to run the battery down to zero and then trickle charge it. Simply resetting the settings did the trick.
Cheers!

Oh and Daryl, If you dont specifically need wi-fi sync with iTunes, if you cut that off it seems to really help the battery life even more. You can try it both ways and see your particular results
xclo,
sorry to hear that. you are the first out of 7 that i have helped that were having the standby drain that did not work using this specific process to fix. i would suggest trying the reset-all again and be sure to drain the batter completely and do a full recharge. if that does not work, i would suggest taking it into apple store for review.
Try the reset, it does seem to make some difference.
At 39% remaining I had gone 1 day, 12 hours on stand by with a usage of 4 hours, 49 minutes.
Currently I have 8% remaining with 2 days, 30 minutes on stand by and a usage of 6 hours, 30 minutes.
Try allowing your battery completely out. To the point the shuts of on it's own, then give it a full recharge.
I did it last night and this morning my phone has been of the charger for 20 minutes at least and I'm just now at 99% on moderate use (facebook, twitter, safari). Hopefully it stays this way all day!
I think davdch deserves a medal for answering all of these questions!
I think resetting all settings is a good idea after applying the 5.0.1 patch, just to kind of give it a refresh! I don't know the ins and outs of theiPhone OS but it does make sense.
Also, draining to zero/off once a month won't do any harm either. I remember when I first got the phone the battery was shocking. I did the reset back on 5.0 and a full battery cycle a few times and the phone gradually started to last longer...
Then the update came and it sent me back to square one... But the reset and battery cycle seems to have helped again, the battery seems to get a little better each day.
This is the best phone I've ever had - I've had an android and a blackberry. The 4S is amazing compared to both of the smartphone platforms I've experienced. Let me tell you - my android phone I had to carry a plug and cable around with me. That is what you call battery drain.
Hope you all start seeing your phone improve soon, follow the instructions here, look through your settings - don't turn stuff of you need/want on/use. But anything you think is pointless being on all day (for me Bluetooth) just turn it off.
Good luck!

Yeah mostly from modest usage. Dropped 2% while I was typing that
well, right now keep an eye on the standby and see how that holds up. this is real bug that the update is supposed to fix, imho. heavy usage like intense web site, you tube, and a lot of talk have always put some beatin on all my iPhones to some point, but never had the standby drop like this before the update and settings reset. the stanby barely move now. usage seem similar to my previous iPhones now. i would go through you complete charge a keep an eye on everything and see how it goes.
I am also very happy to have found this thread among all the complaints on the other one! Thank you, thank you!
I did the update the day it came out. Then yesterday I did the hard reset. (I also didn't see the choice "as new iPhone" but went ahead anyway). Then I let the battery drain. I have to say that the last 1% took forever ironically enough. I recharged overnight to 100% and definitely noticed a difference today. I'm currently at 37% with 4 hrs usage and 13 hrs 21 min standby. I'm fine with charging overnight each night.
I did see the percent drop a few points when I was writing a lengthy email.
Some additional comments:
I hadn't really noticed a big battery problem initially but this is my first iPhone. But I hadn't enabled wifi syncing with iTunes originally. I was able to set up and activate without connecting to the PC. I hadn't been interested in syncing my music to my phone since I still have my Nano. Well, last week I did connect to the PC to charge which made the connection and I wonder whether that had any impact? I have not enabled since the reset.
Also, I saw someone post about Exchange accounts. I deleted my work Exchange email account before the reset and haven't yet added it back. I'm a little nervous about it. But I have turned off "push" and set "fetch" at hourly.
I also have an original iPad and this weekend for the first time it only said 96% after charging overnight. I haven't noticed a difference in its battery life though so far.
I think that's it! Thanks again!

Go ahead. If it still doesn't work try these right after:
* Disable calendar notifications.
* If the above doesn't work, delete your mail, calendar acc,etc.. accounts,.Then perform a hard reset, and re add the accounts again.
*Disable Time Zone, in system services under Location Services.
Good luck.
I use Gmail for email, and iCloud for everything else (Contacts, Calendars, Reminders, Bookmarks, Notes, Documents and Data, Find my iPhone). If I delete everything, and re add everything again, there won't be duplicates, right?
Yikes. I too was suffering from this battery glitch even after upgrading to 5.0.1
As of right now I am at 80%
Usage details are
Usage: 1 hours 25 min
Standby: 6 hours, 10 mins
it was litterly loosing a percentage every 5 min prior. once I upgraded to 5.0.1, I did a restore as a new phone, and reinstalled everything.. little time consuming, but it's a LOT better than before.

it does not look like it fixed the standby drain (i can take my off the charger now and after the first few hrs if i don't use it, it is still 100% sometimes)... corrrect, reset all settings, turn off any system location services you may want to, completely drain and recharge. i really hope this works for you this time 🙂
