Apple on Tuesday released a brand new iOS 11.0.1 software update that includes bug fixes and unspecified “improvements for your iPhone and iPad,” according to the official release notes.

iOS 11.0.1 also fixes an annoying email sending issue with Office, Outlook & Exchange accounts, the company separately acknowledged in a support document on its website.

The new software has a build number of “15A402” or “15A403”, depending on your device, and can be deployed over the air to your iPhone, iPad or iPod touch running iOS 11.0 by venturing into Settings → General → Software Update.

See Apple’s support document for details on the security content of this update though Apple doesn’t seem to be eager to divulge any specific bugs that iOS 11.0.1 addresses.

iOS firmwares can also be grabbed directly from the iDownloadBlog Downloads webpage.

The bug-fix software has arrived a week following the public release of iOS 11. It’s not unusual for Apple to quickly follow up major iOS releases with point updates to address some of the early issues plaguing users like battery drain, slow performance and so forth.

Many post-install issues can be chalked up to the way iOS handles your data and content after a major upgrade with things like complete Spotlight re-indexing, re-running face and object recognition in Photos, performing house cleaning tasks and more.

Performance typically normalizes after a few days.

Have you experience any problems after making a jump to iOS 11?

    Not getting anything under software update, says 11.0 is the most up-to-date.

    • TechnoBuff

      Give it awhile to propagate. it is available on itunes already

    • ikn0witall

      If you have the beta profile install on your phone, uninstall and reboot. It’ll pop up then.

  • philip Mills

    I hope safari gets Faster lol

    • Wilber Alexander Flores

      It does seem slow even on my 8 plus

      • MMA Rules

        Do you have the iPhone 8 by any chance? Because I’m watching videos about the ram management being horrible, such a powerful chip but can’t keep more than 5 apps open, I tweeted Apple about it but who knows they even read tweets!

      • Blacklight: Retribution

        he said 8 plus..

      • Wilber Alexander Flores


      • Wilber Alexander Flores

        It does hAve to reload some apps but depends

      • MMA Rules

        What do you think it might be? They overlooked it? Maybe a software update will fix it? The chip is wayy capable unless Apple is playing safe with the battery

  • edwilk55

    I should know this, but do you have to switch from Beta to Regular in order to get updates to the iOS? Thx guys/gals.

    • ikn0witall

      Uninstall the beta profile and reboot to see this update.

  • Hendo27

    WOW. Battery life lasts twice as long.

    • BlackPantherK

      iPhone 7 Plus or?

  • craig

    my main problem i keep getting what is a real pain is when i load the app store on my ipad or iphone it tends to stick in this load then refresh mode so i cant use it and need to restart my ipad as taking it from the background does nothing….. so lets hope this update did somethng about that :/

    • techfreak23

      Next time that happens, try holding down the power button like you are going to turn off your device. Then when the slide to power off view comes up, let go of the power button and hold down the home button until the view goes away. That will force the app to restart, and if it fixes the issue, it will save you from having to reboot your devices

      • craig

        Thanks for the tip i appreciate it

  • Sailor_V90

    Will it fix iMessage from glitching?

  • burge

    1 Lock screen wallpaper changing size,
    2 Not being able to close the last app in the app switcher until I come out and go back to it.
    3 Screen brightness changing on its own.

    • franco4785

      The screen brightness is tied to “Auto-Brightness” which is on by default now

      • Hendo27

        It still does it when auto brightness is turned off.

  • MMA Rules

    I hope they fixed the ram management on the iPhone 8, such a powerful chip and can’t keep 5 apps open,

    • igobythisname

      say wha!?!

      • MMA Rules

        Yes it’s a thing!

  • Smegmatron

    Just waiting for the 3d touch app switcher

    • Jad Boukai

      Can confirm it’s not in this update

      • igobythisname

        Thanks for the feedback, Jad

  • Blacklight: Retribution

    Waiting on iOS 10.3.1 jailbreak for my iPhone 7 Plus

    • Andres David

      dam man me 2 but updated to iOS 11 seems so tempted I wonder if its guna come out anytime soon?
      10.2 yalu is the latest iOS JB

    • Personally, I think a jailbreak on iOS 11 is more likely.

      • Blacklight: Retribution

        dang it

    • benjamin owuye jagun

      I highly doubt it, Jailbreaking is dying.

  • Matta Fakt

    Only issue I have on 11.0 is that 3D Touch shortcuts are laggy

    • Daniel Moura

      Same problem even in iOS 11.0.1

    • Mr_Coldharbour

      My wife’s 8 Plus 256GB does lag on 3D Touch gesture animations. Running iOS 11.0.

  • Zack Morris

    My setting to use high efficiency photos won’t save. I notice this when I upload photos to OneDrive from my phone. It shows them as jpeg. In the betas it would show as heif. Not sure what’s going on.

  • Daniel

    Not that Wikipedia is always accurate, but they note that 11.0.1 “Fixes issue with Exchange email servers”

    • Iskren Donev

      Sounds about right, some days ago there were reports that email accounts powered by Microsoft cannot be used. I’m not at all surprised if that is what is fixed here.

  • igobythisname

    had a 6S Plus jb on 10.2, 3 mics and a speaker failed, was fortunate to get a replacement on 10.0.2, so I’m jb on that now~holding steady. iOS 11 looks cool, except for that fugggggly control center! jailbreak-4-life! as always, appreciate the info/updates, thanks iDB team!
    keep the 6SPlus pwned on 10.0.2 and hopefully get the iPhone X?!? decisions decisions….
    edit: oh yeah, the removal of the App Store and ability to easily sync home made ringtones on new iTunes update is a major disappointing factor!!! backing up app .ipa’s is pretty crucial! Apple really fuxxxed up with this one!

  • JulianZH

    no problem at all on my 7plus running ios 11, but update it anyway.

  • Yaseen AlSuwaidan

    I wonder if the Bluetooth trigger was fixed. To explain the bug, I you enabled the Bluetooth in control center and disabled it again. If you go the the settings>>bluetooth, you will find it still enabled!!

    • Firedomain

      That’s already been covered. Disabling Bluetooth or WiFi in CC will only disconnect devices & leave the radios on (for watch connectivity or something.) I disagree with this behaviour since when I want it off its to save battery!

  • Nathaniel

    Only Apple knows about this feature: draw a keyboard character in notes, and when you go back to your notes list, you’ll see that it’s smart enough to identify what the character is

  • notewar

    Im trying to do OTA update for 11.0.1 but i kept getting “Software Update Failed”. Do can i fix this?

  • Muhammad Saleem

    Slow command response

  • I was hoping for a update of watchOS too. My Series 2 is very laggy after the update for watchOS 4.

    Anyone having this “problem”?

  • Firedomain

    Geofence icon is in the status bar constantly from the apple weather app when Apple Watch is connected. Was a b**ch to find since they changed the legend in location privacy so it doesn’t tell you what’s using a geofence anymore! Changed the weather app from ‘always’ to ‘while using’ to get rid of it. Haven’t tested in 11.0.1 yet.

    • techfreak23

      Yeah that has been annoying me like crazy. I know it’s always been using my location but seeing that icon in the status bar makes me think my battery is draining a lot faster lol

  • Sombir

    I have informed Apple about bugs in iOS 11 but they haven’t fixed.
    Once you save any new number and after you save that number you still can see add number option on dial pad.

  • lewis

    That’s already been covered. Disabling Bluetooth or WiFi in CC will only disconnect devices & leave the radios on (for watch connectivity or something.) I disagree with this behaviour since when I want it off its to save battery!

  • Zhimin BrownEyez

    iOS 11.0.1 Geekbench drop significantly for iPhone 7 Plus compared to iOS 11.0, users refrain from updating !!!

  • Giant Catfish

    I had issue – set brightness level to where I wanted it and it kept reverting back to 0 on it’s own. Tried rebooting after setting and still went back to 0. Spent half hour chatting with support. Took support time to find certain settings because they were moved in 11.0 update. Took 3 or 4 days and finally stopped doing it.

  • Colin Weaver

    he said 8 plus..

  • anonymous

    About time …. anyone dealing with videos thru safari bugs shit never plays

  • Benedict

    “It just works…” 😉

  • Mr_Coldharbour

    Did Apple fix the Notification Centre bug where it doesn’t remember your last used view and always reverts to the Notifications view even though your last known used view was the widgets view? This issue is not present on iOS 10 and below. Only reason I ever use NC is for widgets. I reported this issue hundreds of times and no fix or even an acknowledgement.

    • gudorian

      Might not be a bug but intended behavior, tho I agree that it’s annoying in some use cases, I usually just want to check notifications so, for me, this behavior ends up saving me time.

      Can also confirm that this haven’t changed in IOS 11.1 Beta 1.

      • Mr_Coldharbour

        Great, all the more reason to stay on iOS 10.3.3.

        Also if this is intended to default to the notifications view (which is page 2 of NC), then might as well make notifications view page 1 of NC and widgets page 2 of NC. I mean, page 1 comes before page 2 and thus should be the default view. I mean how come if you swipe to page 2 of your home screen and lock your phone then unlock it again it’ll take you the page you last were on (being page 2 of the home screen in this example)? Why is NC the only exception. The BEST thing that ever happened to NC is widgets, they should be promoting that more and making it the default screen or at least make iOS remember the last NC screen you were on, like it used to on iOS 10 and below. This way of there’s makes no sense or logic at all.

  • Nirvana

    recommended for 5s guys?

  • Jose Gonzalez

    IPHONE 6 PLUS running sluggish and sometimes some apps crash after updating to latest update seems to run alot smother see how it goes……

  • Jennice Lim

    Speaker problem! Only can hear sounds with headphone, sigh…

  • Tony Story

    Ios11.0.1 fixed most low definition photo’s and made them more high definition . (ie iPhone 7 Plus).
    Still slight battery drain even after offloading ( not deleting) unused apps. Tested battery efficiency (standby versus usage) and all checks out , ergo the problem is of apple’s making , but hey , be patient (64 bit is going to use more power than 32 bit) and wait for iOS 11.1.0 and see what improvements follow after a few days….

  • Muthamil

    hi, today I have updated IOS 11.0.1 in my Iphone 6 (64GB), after this music player is not working. When I try to open , it opens and closes immediately. Any of you face the same problem? If so please help me to sort it out

  • Garren Seifert

    My brightness keeps on changing non stop going up and down right in front of my eyes and there isn’t an auto dimmer button to turn on or off anymore
