    Ok .. Let's try and find some common things about the sufferers here.. If you are suffering, did you upgrade via iTunes using a cable, itunes wirelesly or OTA (wirelessly from your handset without iTunes)? I'm suffering from battery drain and I upgraded OTA.

    I updated wirelessly (3 phones) no problem.

    this os just disappoint me so much.

    i went to sleep and wake up 7 hours later, the battery life dropped from 100% -> 73% without me opening or doing anything with it! i just wanna get a downgrade now

     

    -3GS

    Recharge overnight.  Wake up refreshed, with a full battery.  Works for me.

    I also hit the rapid battery discharge on my Iphone 4s following the update to IOS 5.1.1.

     

    After trying shuting down location services and wifi nothing changed.  I was still seeing the rapid battery discharge.  I did a reset of network services which did nothing to stop the discharge.  I then reset the entire phone and restored from backup at which time a new copy of 5.1.1. was downloaded and installed.  Still had the battery discharge.

    I then removed my Exchange 2003 Sync account and restarted the phone and also reset all settings.   Finally this stopped the battery discharge. Then I waited for the battery to recharge and I power cycled the phone.  Then I added back the Exchange 2003 account and battery discharge started back up immediately, so I remove the account again to get the battery discharge stopped. 

     

    So this phone has a sure issue with 5.1.1 and connecting to exchange 2003 via activesync. And I cannot get the email I need now...

    Does anyone get the idea from all these messages that the problem is something to do with Exchange mail accounts?  Maybe the problem isn't with the iPhone but with the way Exchange accounts work.  Probably it would be a really good idea to stop any push type accounts (including iMessage) before doing an update in the future.

    Hi Folks,

    after a full reboot of the iphone everything is running fine now. Battery is dis-charging like before with 5.1.

    Do not know what it was.

    all the best

    Yes, that's exactly what causes it. And has caused it on some phones after every update and frequently between updates (but those are distributed in time and don't show up as obviously). The Exchange ActiveSync protocol is a very buggy protocol. Always has been. On every device that uses it (not just iPhones). ActiveSync doesn't recover from lost connections well. It opens a new connection, but keeps trying the old, dead connection. This uses data and drains the battery. So if the update process interrupts a data exchange with the mail, contacts or calendar apps it leaves stale connections and causes the symptoms you see. There are other things that can interrupt a connection, such as wandering away from a WiFi hotspot or loss of the 3G signal, and when this happens battery drain starts with no apparent cause.

     

    This information has been posted thousands of times in the forums over the past 4 1/2 years, but it has to be rediscovered after each update.

     

    The fix is to close the stale connections. You can do this by deleting the Exchange account, rebooting the phone, and adding it back (without the reboot adding it back just restores the buggy connection). Also by turning the account off and rebooting. And someone just suggested turning off SSL (which will close all open connections), rebooting, and turning SSL back on for the account.

    Ok so as an update to my post before.

     

    Draining my battery to zero percent until it shuts down itself and then charging it back-up to a hundred percent fixed the issue for me.

    Looks like I'm going to have to restore.

     

    For those saying it's not a problem with the 5.1.1 update, I'm sorry, but it is.  I had the battery problem with the iPhone 4s when it first came out.  It was fixed with the 5.1 update (I loved it... would finish the day with 70% left on the battery)... and now immediately after updating to 5.1.1, the problem is back and I'm back to being down to 30% or less with the same usage.  Considering that the only thing that changed was the update to 5.1.1, it has to be the update.

     

    I drained the battery completely and recharged - didn't do it.  Reboot - didn't do it.  So, now I'll restore it as a new phone.  Pain... in... the... butt.

    This is the blame of stupid 5.1.1 for sure. I have 4s with perfect battery life since 5.0.1 - even in heavy usage about 30% from morming to evening... If light - 80%.

     

    What I found after 5.1.1 - the battery while iddle state is the same or even better. But some application, I used to play or wark before, makes the bodu really hot, uncomfortable hot. The temperature rises near the sim slot.

     

    I suggest that something wrong with 3G connection. But surfing and receiving e-maild doesn't makes this hot, only some games for me - they are connected to gamecenter.

    I'm just glad that this is fixed. Issues like this are inevitable when upgrading. I sure appreciate the effort from the team. /___sbsstatic___/migration-images/184/18442789-1.gif

    I'm sorry, but it is not a problem uniquely with the 5.1.1 update. It was a problem with the 5.1 update. It was a problem with the 5.0.2 update. It was a problem with the 5.0.1 update. It was a problem with the 5.0 update. It was also a problem with every other release of iOS since the iPhone first came out. If you want to believe it is a problem with the 5.1.1 update that is your privilege, but believing it won't fix the problem, and is illogical considering that you can find posts describing the identical problem after every update, and also between updates. The cause of the symptoms and how to fix it have been posted several times in this and other threads, so you can solve the problem by doing a little reading.

    I experienced this problem with my iPad after upgrading to 5.1.1.  I did as was suggested in this post and dropped my Exchange email connections, rebooted my iPad, recreated the Exchange connections and now the battery life is back to normal.

     

    I have also been very careful to make sure when I charge my iPad (newest version) that I only use the charger that came with the iPad and not one of the ones I have from other iPod and iPhone devices.  This seems to have improved the time it takes to recharge the device.

    Another "fix" for the whole exchange issue is pretty simple . Set your exchange acct to fetch and fetch settings to manual (or just set to manual) so that your email comes in when you open the mail app. I know some will say they have to have their email pushed but the reality is unless you are looking at the iPhone mail app constantly there is no reason for your mail  to come in and sit in the inbox until you are ready to actually open and read it. It will download in seconds after opening the mail app. Myself, with 3 accounts setup I ALWAYS have some sort of mail popping into one of them so if I looked every time the bong went off telling me I have a new message thats ALL I would do all day is open and stare at the email app. (I am in IT so yes my emails are important for me to get but dont need them within a second of them coming in, just sayin)

     

    So perhaps checking your email every 30 minutes will keep you on top of things AND solve this exchange push issue giving you a stable device with plenty of juice to make it through the day. Just a suggestion for those who would like excellent battery life on their devices.

     

    PS Lawrence is dead on. Do your research. Although iOS 5 did have some inherient issues that were solved with the updates.

    To me, is suggests a possible short of the SIM card to the phone body.  There is a simple was to fix this.  Pop open the SIM drawer, make sure the card is properly seated, and the close it.  retest.  Can't hurt.

    Lawrence Finch, thank you for your fix, after resetting all settings, resetting network settings, then doing a full restore, i was still suffering from a fully drained battery in less than 5 hrs from100% charge. Due to a fixed profile setting on my company issued iPhone 4 I  was unable to delete the exchange account as some forums have suggested, the option to delete is disabled,  but was able to turn off the mail, contacts and calendars switches as suggested, reboot, then switch them back on. You're a gem!
