iPhone OS 3.1 Problems: Random Shutdown, Poor Battery Life, Bricked iPhone, Slow Performance

iPhone OS 3.1

According to TUAW, iPhone users are facing many issues after upgrading to iPhone OS 3.1.

iPhone users are reporting the following issues after upgrading to iPhone OS 3.1, which was released a week back:

  • iPhone randomly shuts down

  • Poor battery life

  • Bricked iPhone

  • Slow performance

iPhone randomly shuts down

As per this Apple Discussions thread, iPhone users are observing a strange issue after upgrading to iPhone OS 3.1. They are reporting that their iPhone randomly shuts down.

Header22 first reported the issue after upgrading his iPhone 3G with iPhone OS 3.1:

Ok, I updated lastnight without a hitch. But now I get random complete shut downs of the phone. It has happened twice. In both instances the phone has come back after doing a hard reboot. Anyone else having this problem?

It seems to be occurring several times in a day and the only option the user has is to hard reset the iPhone. Users have tried to restore their iPhone but that hasn’t helped.

It seems to be affecting many iPhone users as there are already more than 640 posts and 44 pages on this discussion thread.

Some users are reporting that they have got a replacement from Apple because of the issue.

Poor Battery Life:

According to this Apple Discussions thread, iPhone users are complaining that battery life, which is already a precious commodity on the iPhone gets even worse after upgrading to iPhone OS 3.1

akarelin started the discussion thread by reporting:

I've made the so long attended upgrade to iPhone OS 3.1 and strangely battery life has got even worse than before. The phone is using 10-12% of the battery every hour of standby; usage counter grows by 35-40 minutes for every hour of standby. This happens with a clean install and just email setup (mobileme with push), with restore or partial restore. Turning push off only makes it slightly better.

There have been more than 250 posts and 18 pages on this discussion thread. Battery life depends on the usage of an iPhone user so it is not conclusive if this is indeed an issue as we have heard some reports that battery life has improved after upgrading to iPhone OS 3.1.

Bricked iPhone:

This is another strange issue being reported by users after upgrading to iPhone OS 3.1.

ChopperPilot was the first to report this issue on this Apple Discussions thread:

I have the current Mac OS X 10.6 and iTunes 9.0, went to update my iPhone 3G to 3.1 and now my phone is useless. Tried all the tips on tech support with no luck. iPhone stays in recovery mode. I get error codes 2006, 1611, and 26 during different attempts to recover and restore.

douglasfitz might have found a possible solution to the problem:

I had downloaded the 3.1 update during the first rush after the announcement, and I believe my file ended up corrupted. Every time I restored, therefore, iTunes would attempt to reinstall the corrupted updater file.

The trick is to remove the update file from ~/Library/iTunes/iPhone Software Updates (in this case, iPhone1,2_3.1_7C144_Restore.ipsw). After that, I restarted iTunes, reconnected my phone, and had it download and install a fresh update.

If that doesn’t work, you can checkout this knowledge base article to see if it helps.

Slow performance:

One of the things, users observe after upgrading to a new version of iPhone OS is usually snappier performance. But as per this Apple discussion thread, iPhone users are observing poor performance after upgrading to iPhone OS 3.1.

Elliot confirms that he is observing the same issue first reported by SamVG on this Apple Discussions thread:

I too am experiencing extremely slow response on my 3GS. Swiping the unlock often has no feedback until the phone is unlocked. Pressing the home button when the phone is sleeping appears not to wake the phone for 5 seconds or so.

Are you facing any of these problems? Please let us know in the comments if you have figured out a way to resolve them.

Let’s hope Apple releases a patch to fix these problem.

  • That is ScAry has Any of those Iphones been 3GS?

  • Angel

    my 3G is in a WORLD of shit right now. i get that shut down thing a lottt and i hate it. i swear apple of 3.1.1 isnt out soon…

  • Jacob

    My iPhone is doing all of those. How can I fix it ?

  • alex

    my iphone also experience all of that and extremely slow

  • Daniel

    That's wierd I haven't had a single problem on my 3.1 3GS.

  • The only thing that heppend to me and it only happened once, was it seemeded to be shut down…

    I just started pusing the home button, then the on button… not at the same time… nothing happened, so I put it in my pocket until I left the store to check it, and then it responded.

    It was like paused for a while with a black screen…

    If anything, these problems wont speed up a new version, but will most likely postpone it more for testing. Maybe they will throw a quick fix out there, but then will most likely have to test the next version thoroughly..

  • NarsEsp

    Portuguese iphone 3Gs user and i am experiencing all of those.

  • Camil

    I have 3gs and so far I haven't had any of those issues.

  • Eng

    The only problem im experiencing is the battery life.

  • Eng

  • lis1ric@gmail.com

    My GPS is dead after 3.1 I have a 3G. Me thinks I'm getting a 3GS

  • SKYWAY211

    I was having trouble with my iphone 3g 8gb turning off randomly. I restored my phone but did not restore it from a back up. I restored it as a new phone and haven't had any problems since then. This may work for some of you also.

  • Ted

    My iPhone did the random shut down thing. I called Apple Care, and they replaced my 16GB 3G with no problem. For whatever reason, I've had no problems with this replacement phone. The guy at Apple Care said that they're studying the problem and are well aware.

  • J

    notice that my iphone runs SLUGGISH now. the email software CRASHED. never seen it before. had to reboot to get it back to normal. didn't really pay much attention to battery life but noticed i'm charging it more often than before now.

  • slamr

    My battery lie was reduced by approx. 25%. Can barely make it thru the day and I'm a light user!


  • Cristv77

    so weird to hear that from an angel

  • CristV77

    only a couple time shut off randomly, and then no more prob, battery yes, its still an issue, non of the other things tho

  • joe

    nothing wrong here on 3.1 3gs…..

  • Bill

    This is why I'm sticking to 3.0 for now.

  • jorge

    it suck all the updates suck, DO NOT UPGRADE THE FIRMWARE as far as i know 3.0 works fine

  • BusyChild

    Has anyone noticed these same issues on 3.0.1? I haven't had the time to upgrade just yet, however my 3gs is having all of these issues. This started 3 days ago with the battery drain. Another thing I noticed, for instance is my battery life will be at 30%, I'll then lock the screen and a few moments later log back it and it will be at 90%. Today it showed 20% battery life, I attempted to receive a call and it shut down like it was dead. Plugged it into the wall charge, and powered it back up…now showing 60% charged. What the heck is going on?

  • Anonymous

    I have no problem after upgrading both of my iPhones 3g and 3gs.
    I first upgraded iTunes to iTunes 9 and then upgraded both my
    iPhones from 3.0.1 to 3.1. Actually I find it better than 3.0.1.
    iPhones are now not heating as like 3.0.1. Both 3.0 and 3.1 looks
    better than 3.0.1

  • Dave

    I updated my Iphone 3G from 3.0 to 3.1
    I used PwnageTool to Jailbreak it, and then unlocked it with Ultrasn0w. Everything went fine, except for a few of things.

    My Battery is going down about 10% every hour. This is with everything off (3g, edge, wifi, location, push email).

    I have exeprienced some crashes from Cydia when 'reloadind data'

    There is no carrier Text, only the signal bar. In General – About, it says NEtwork Unavailable, but the phone works fine.

    Winterboard no longer works, as well as things like AppBackup.

    I am starting to think I should have held off. The main possitive is that it does seem much faster.

  • Nick

    both my wife and my iPhone's are slow as $hit right now. Interesting thing is that I upgraded mine to the most recent firmware to date and she has NOT. BUT, her phone is acting slow just like mine. Not only DROPPING every single call, but the unlock slider is slow, keyboard response is slow. everything is slow. this is ridiculous given the amount of money we dish out for this $hit.

  • Andre

    Upgraded my 3G Wed with PwnageTool and haven't experienced none of the problems mentioned in fact I think it's faster then 3.0.1, texting is a lot quicker and phone more responsive overall. Battery life seems better also and now I don't have to turn BT off twice.

    The only problem I have is with the carrier logo not showing up, but that's easily sorted with a Jailbreak app from Cydia.

  • Debbie123

    Yes, mine is an Iphone 3GS.
    Just experienced the shut down problem last night.
    The screen went black and no matter how I did the hard reset for
    5mins, it couldn't turn on.
    Tried connecting to iTunes, after fumbling for 2 mins, the apple logo
    suddenly turn on and I did a backup and syncing.
    Hope Apple will look into these matters and get them resolve quickly.

  • I haven't updated, thankfully, because I'm on a 3GS and was waiting for the jailbreak tools to be released. But I'm very concerned now – if I run into a problem and need to restore, I'm screwed as I'll be forced to upgrade. NOT good.

  • geewhiz71

    I updated from 3.0.1 to 3.1 jailbreak using pwnagetool yesterday. What a disaster.

    I have all of the problems above and:

    1. Google Sync flakiness, works occasionally, every 2 hours I have contacts then I don't
    2. SLOW backups (up to 1.5 hours) just to backup the phone one day later.

    Being an Apple fan, I upgrade to everything and rearely get screwed. This is one bad apple. Avoid 3.1this at all cost.

  • geewhiz71

    Downgrade to 3.0.1 and wait for 3.1.1 and save yourself hours of frustration and keep a usable phone.


  • wow glad my computer is down at the moment and I cant upgrade to 3.1 and dont have a bricked phone

  • infiltrator

    Hello everybody,
    I upgraded my iphone to 3.1 just as the firmware appeared. besides the problems mentioned in the article I have a strange one with my wireless. When I wake my phone from sleep mode and I launch safari or any other app that uses wireless is not loading the data from the first time. I have to stop loading or quit the app and then resume.
    This is the worst update ever.
    I have iphone 3g not jailbreaked yet.

  • Douceswild

    I'm experiencing most of those issues, mainly the slowdown in performance and battery life. Another issue you might want to add that I'm having along with many others (after some reasearch), the keyboard clicking is muffled now. When typing a text or email (or any text)the clicking is significantly lower than before.

  • Eddie

    You can still download the 3.0.1 software from another site, I did, don't remember where though. I just Googled for it.

  • Carsten

    Another bug with OS 3.1 / itunes 9: smart playlists are screwed up in iTunes during sync, resulting in showing completely different files in some conditions or a wrong sorting order in other sitations. Really annoying for podcast playlists!

    I experienced worse battery life and a random shutdown as well.

  • junixG

    i have a 3gs and im using vista. i had the same problems with os 3.1.
    i restored via itunes then set the auto lock to 2 minutes. i've had only 1 auto shutdown in the last 48 hours.

  • anold

    i have a 3g and its working good… even though i cant unlock it anymore 8(

  • arnold

    syncing is slower though….. really slow.

  • mik@mik.com

    me too!!!! hello apple-bums wake up and release an update and bugs fix… my iPhone has a PC-like symptoms…

  • Charles

    Yep, Poor battery life. Also seem to loose my carrier. Can't make or receive calls, don't receive text messages. Hoping for a quick release of 3.2

  • Richard

    Yes, I am seeing the random shutdown on my O2 3G since the 3.1 upgrade. I upgraded 3 days ago and its done the shutdown each day – during night so not even noticed until the morning.

    Not seeing the speed issue or the battery problem.

  • karl

    theyll probly just release 3.1.01 which will fix these issuies or something then theyll make a jailbreak and unlock for that so if you ask me theres no point in upgrading.

  • itheemperor

    lis1ric i was having the same issue with GPS No signal at all, so i charged the battery to its maximum and then opened copilot live it ill say determining position just left it like that for a couple of hours and when i came back GPS was connected try this but am not an expert its just my experience which happened accidently. take care

  • Me

    Apple is gay. My phone was stuck in recovery mode for a day. Had to be replaced at the Apple store. The phone they replaced it with erased my music files evey time I opened it.

    Apple sucks, and so do y'all!

  • John

    Yup. Add me to the list of those experiencing all those problems except for the bricked phone. Random shut down, slow, and a noticeable decline in battery life are all problems though.

  • steveo

    I have a 3GS and experienced random shut offs a couple times yesterday, and the battery life diminished very quickly. Also happened to a co-worker of mine with a 3G. Definitely a 3.1 bug!

    We get an update next friday to enable mms, so hopefully that update will also fix these problems.

  • CheeseEater

    I think the shutdowns (yes, I am having them also) are not from Apple, but from AT&T to increase their available network capacity (fewer phones on the network at any 1 time).
    The decreased battery life is caused by the United Nations leaching power from our phones to combat global warming. I use the battery meter as an egg timer now, from 100 to 0 is just about right to get a perfect egg every time.

  • Yuriy

    mine 3G and also slower, was shutting down yesterday at 1:25AM

  • Yuriy

    also just because i was reading news in my 3G in half hour i 50% less battery – extremely fast…..

  • Glad I did not upgrade and still working Fine!!

  • Chase

    Updated a week ago and have NO problems!

  • Yuval

    My 3G became sloooooooow, it hangs all the time, it's terrible !

  • I "upgraded" my developer's 3.1 to the officail and accidently let it do a restore. (I always do a fresh install) Noticed that my battery discharged to empty while driving, with it connected to the car charger. As it's over a year old I figured that my battery was dying. Bought a replacement battery but decided to reflash while waiting. Instantly battery issue went away. Actually the battery's lasting much longer than before, without any charging during the day. Go figure….

  • This problem seem to be common. My 3gs iphone did that once and because I'd known of this issues, i did not upgrade my firmware.

  • 2221

    Im trying to turn on the OS 3.1, THE SYSTEM IS DEAD…. HELP!!!!!!

  • christian

    good thing i decided to read up on 3.1 before updating. but as for the slower response issue, i have had similar problems for a while since i bought my 3gs. never really thought much about it, but it does tend to get annoying. any solutions?

  • madmatter

    …same shutdown issue is happening with me. Having to do hard reboots approximately every other day…and locks up. Fix this Apple.

  • Bob

    Something is up with Apple. I got my iPhone in Japan and have been living with 3.0 with no problems. But now when I read this and the other comments I remember I singed some paper when I first signed up last month that said something in English saying that the phone company (Softbank) was not responsible for firmware upgrades and any update you did will not be covered under warranty at your own risk. It's almost like they knew in the future or in the past from firmware upgrades that this was going to be a nightmare. So they warned users flat out front. Either Apple knows that the firmware is crap and put new versions out in time for the PR bukake just too keep investors happy or they have no clue what is wrong with each run of iphones from China (but "designed in California" please blow me) hence why no one can pin point why these problems are so random over many iphones.

    I'm not going to upgrade. As there's some old sayings. If it ain't broke why fix it? Yes why upgrade if the phone works. I don't need mms or video editing fix. I need a phone that will work before I had to terminate my contract as google will have a good phone in 2 years I hope?!

  • Austin TX

    I get the same on my 3G. maybe every other day, black screen couple of minutes later apple comes back. I'm also getting far more dropped calls and odd no signals.

    Have Apple lost it or what; this company feels more like Microsoft every day!!!

  • haytham

    i have the same problem my iphone go in coma

  • Brady

    I had massive problems and had read a thread about it only hitting phones with less than a gig free so I free'd up some space and haven't had a crash since, however my battery life is weak now and it is still slow.

    Regardless, it pisses me off that my iphone (3g 8gb model) is now essentially a 7gb model because if I fill it up then it will die.

  • I am having the battery life issue..and I had one auto shutdown since I upgraded a week ago…mm looks like Apple rushed the 3.1 to release it in the last iPod key note…so they gave a half-baked product… too bad..too bad…hope they fix this soon…next time Apple stick to what you have completed..and ready to present..OS 3.1 is giving some much issues that should still be on the developers hands..

  • Kdel

    Does anyone having those problems with a 2G (1 st gen) iPhone? I was ready to do the upgrade to 3.1, but now I'm not so sure…

  • Em

    My iPhone 3GS battery life has gone down by a lot! 3% drained in 20 minutes while in standby mode! The biggest issue I have is that unlock slidebar won't respond and other apps wont respond when I tap onto them. Fix is APPLE!!!

  • patrat

    The screen black out happened on my 1st gen iPod touch. the strange thing is that it is on 3.0

  • Bob

    Yes, it happened to my 3GS last night, after 5 hours of attempted firmware upgrades, no success, tried iTunes from both Vista and Snow Leopard. I think the issue could be it wasn't communicating with the Apple server? AT&T store reloaded the 3.1 firmware and got it back to a clean slate in 30 minutes today.
    Phone is/was clean, no jailbreaking, kept getting error codes, 4, 16, and others and phone was stuck in a state of needing the firmware upgrade to complete

  • I can't believe that Apple is now getting like Microsoft, constant problems.

    My iPhone was working fine on 3.1 until I installed a new update of it the other day,
    now it shuts off every 40mins or so & 02 here in UK are no help.

    Apple said wipe & new factory reset. I did that before I even called them & it's not helped.

    No one seems to know what to do so I'm bloody stuck with my THIRD iPhone in less than six MONTHS. I am SO pissed at Apple as this is my business phone.

    Apple, you charge us enough for everything so SORT THIS OUT or I'm off back to Microsoft & PC's.

    NOT impressed :-((

  • Chuck

    After ugrading to 3.1 on my 3G, I lost my GPS, "Maps" app won't populate a map, just has link to "legal Notices." THE ONE APP I USE EVERY DAY! Uggh. Apple, Help!

  • EMRO

    Dave, I have exactly the same "problems" with my phone but I have a 3GS Iphone Jailbreak with Pwnagetool. I tried every single step to downgrade or re-jailbreak without success. Every time I got the same "Not Available" issue. Also I lost the "Internet Tethering" under setting>Network and the "cellular data Network.

  • Nick M.

    that problem is because you are under the list tab and it there has a link to the legal notices and no map. try to hit the bottom right corner button and switching to hybrid map mode than see it that works. 🙂

  • Frank

    Yeah mine has been slow as fuck since 3.1. Swipe to unlock is slow, home button response is slow, answering and ending calls is slow, apps launching slow. Sometimes I want to throw this POS at a brick wall!

  • Charles

    I have a 3g and while I'm not experiencing any of these symptoms, I am having problems with mail. 2 or 3 seconds into lauching mail, it shuts down. I hardly have time to see what new email I have. I tried deleting my email accoutns and then re-establishing them but…that doesn't work. This has only started since 3.1.

  • AppleAreScammers.

    Random shut downs…….
    anyone know if an update bug fix?

  • Tom Thierfelder

    I am having the same problems and have not found a solution anywhere. uggg

  • Brad

    sure has, mine is a 3GS same problems as reported

  • whoochacha

    yep mine just went black on me.. but managed to save my darling by holding the start button and the hold button (top right) for about ten freaking seconds.. then connect to itunes.. then itunes asks if me wants to restore.. but with the price of having all my data my naked chics' pic deleted.. so i said 'no way hose'.

    then i reconnect it.. and now its ok..

    doing my encryption as i am typing this..

    yep.. DO NOT UPGRADE TO 3.1 watever…
