IPhone slow after OS 4.1 upgrade

Hi
after upgrading to iOS4.1 my Iphone 3G has become considerably slow compares to how it was with 3.1 and i was wandering how i can solve the problem.
tried a restore but nope.
slowest application seems to be the calendar which is the one i use the most
it is quite annoying as it takes time to respond when i type something in and take some xtra time to load any app.
anyone having same issue? any help? thanx.

Hey there, I own an iPhone 3G with iOS 4.1 as well, and it runs alot smoother than the 3.1.2 that i was running before. The only advice i can offer you is to go to Settings>General>Reset>Erase All Content And Settings. (I advise you sync your iPhone first.) it will take about an hour and it is a master reset so you'll have to re-sync it and reinstall everything back the way you had it. Let me know if it helped!! And if there is anything else i can help you with.
Thanks, SCSmith443

    ipad 4 retina display is slow after iOS 8, also upgrade to iOS 8.0.1 i think and safari is slow, animations are slow, and i can't restore it to iOS 7, there it was great. i mean its like my iphone 4 with iOS 7 in its best days. i hope no to get stuck again, i mean please let me go to the iOS 7)).

    Upgraded my ipad4 from ios6 to iOS 8 because the new WSJ app required it. HUGE MISTAKE!!!!!!! I can maybe understand some apps being slower but not Safari or Chrome. Apple must be throttling back the ipad4 processor even more with ios8 to force an upgrade to the next gen iPad whenever it arrives.

  • ITunes store wont open on my iPhone 5 after the iOS 7 upgrade

    I was able to use it for a few days after the upgrade, but now it keeps crashing every time I try and open it. I have tried the date/time/auto thing and I have tried it when I am connected to wireless.

    Some folks that have had the problem you are having had to backup their iPhone on iTunes and then Restore their iPhone as a new in-the-box Factory Settings iPhone.  After this they brought their iPhone up as their new phone, iMessages worked, then they went back to iTunes and restored with their Backup which contained all their data, photos, music, etc. 

  • Browser Load Slow after 10.4.6 upgrade

    All my browsers - Safari, Camino, Firefox - load pages really, really slow after upgrading to 10.4.6. The browsers are all the latest versions. I've read it could have something to do with the recent Java update, but haven't found a good way to resolve the issue. My internet connection is fine.
    Any suggestions? Thanks. Terry.

    I have 4.2.2.1 and 4.2.2.2 set in at least one of my locations. I havenn't noticed that much diff' personally. Many do gain from this inclusion. It's fairly well known by now.
    I guess the main point would be that it is an ISP issue as opposed to a Safari problem.
    Apple Forums are under supported and sometimes won't load. When I get puzzled I use http://www.dslreports.com/forum/macdsl as a Test. It is an interesting Apple oriented site and loads "instantaneously" for me.
    Good Luck, JP

  • Airplay doesn't work anymore on my iPhone 6 after iOS 8.2 upgrade

    I'm using Airport Express (2nd generation) for streaming music on my stereo from 2 iPhones: one 5 and one 6. Since I upgraded my iPhone 6 to iOS8.2, Airplay is not working anymore on this phone: Airplay icon is visible and actionnable, but it doesn' produce any sound on my stereo. Airport Utiliy is OK.
    Airplay is still working on my iPhone 5 which hasn't been upgraded.
    I did a hard reset of my iPhone 6, with no success.
    Thanks for your help.

  • How do i access appstore from iPhone 4s after the ios 6 upgrade

    i am not able to access the app store from iphone 4s after upgrading to ios6 - any suggestions

    The old data will overwrite the new, so you will have to manually import the new data to a computer somehow and figure out how to transfer it manually back into the phone once the old data is transferred. Best of luck.

  • I just synced my iphone 3gs after downloading the Safari upgrade, now my iphone won;'t open any apps except the ones loaded on my phone when I got it.

    I just synced my iphone 3gs after downloading the safari update.  Now I can't open any apps except the ones that came with the phone.  I have tried rebooting, turning it off and on. 
    When I select the icon, it goes to the page then returns to my screensaver.
    It was working well before the update and sync with my Acer netbook.  Have never had any problems with itunes store or downloads.

    this happened to me with my iPhone 4. I researched the problem and found this :
    "The reason this happens is because every time a downloaded app is opened it checks for your itunes password for validation that you are authorized to open that app (as it may contain personal info). From time to time the iphone 'forgets' your itunes password. You can fix the missing password by syncing the iphone with itunes or downloading an app from the app store and entering your password that way.”
    And to fix it, all I did was download a new app, or delete a current one, I used Facebook, and re-download it.
    Hope this helps

  • Why is my macbook pro running slow after os x yosemite upgrade

    Why is my macbook pro running so slow after os x yosemite upgrade

    Please describe the problem in as much relevant detail as possible. The better your description, the better the chance of a solution.
    For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What other changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

  • Wifi very slow after iOS 6.1 upgrade

    Per iOS 6.1 I had no problems with my phones wifi.  After the upgrade however the phone will connect to it but data transmission is extremely slow.  Speed tests show that my connection speed on wifi is under 2Mb as where before the upgrade it was around 30.  Mail will not download now either without turning off wifi and going to lte.  Have also noticed that lte will randomly turn off and go to 4g while I am using it.  The phone usually then goes to no signal and then back to full.

    My
    iPhone 4s
    on ios 6.1 is so slow ..... I am getting irritated first time with apple product mainly after step up on ios 6. Everything works great in ios 5.1.1 .....
    Please fix this I cant download movies from itunes It takes so much time.....

  • Powerbook G4 Running SLOW after 10.4.4 upgrade

    I am new to Mac and just set up a new PBG4. I installed all of the updates as soon as I set-up OSX for the first time. Now, everything runs slow, especially Safari. Anyone else experiencing this? Any suggestions?

    How did you upgrade to 10.4.4? Did you use the Combo Updater or the one provided via Software Update? If the latter, I suggest you download the Combo Updater and reinstall the update. Before doing so, however, do the following:
    Boot from your OS X Installer. Be sure to use the installer for the version of OS X you have installed. After the installer loads select Disk Utility from the Installer menu (or Utilities menu if using Tiger.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    If the computer continues to run slow then I suggest downloading one of the several cache cleaning and maintenance utilities and clean out all your caches, run the maintenance scripts, and check for bad fonts. Read the FAQs on optimization and maintenance at The XLab FAQs. Contrary to other advice repairing permissions will not make OS X run faster.

  • Airport performance slow after 10.5.8 upgrade

    After the 10.5.8 OS upgrade I noticed that my MBPro's wifi internet was really slow, less than 2Mbps when it should be 10 - 15Mbps! I thought it was Comcast but tested the speed with the LAN Ethernet connected and the speed was normal. I tested it on my wife's black MacBook 13 inch and got slow speed on WiFi too.
    I tested the speed on my hackintosh Dell Mini 9's WiFi and the speed was nice at 15Mbps. So I figured it was a firmware issue. I couldn't find anything similar to my problem here in the discussion so I was going to post the issue but then, as if Apple magically saw my issue, I received an Software Update notice about an update for the Airport Client that fixes performance issues when running on battery. So I ran the update and it fixed the problem. So for those of you out there who are wondering why their MacBook Pro and MacBook 13 has slow bandwidth, try the update.

    I have the same with my NAS. In the beginning of Leopard the same thing happened, with the connect to the server a Finder window of the disk would open. But in the last 4-5 version everything went as it was supposed to. And now I end up with all these open windows ;-(. Annoying.
    Detail, I connect using a SMB server.
    Would appreciate it very much if this is solved in the near future.

  • Lenovo B590 I3 slow after Windows 8.1 upgrade

    Am looking for the best fix for slow laptop after Windows upgrade from 8 to 8.1

    Dear, alanj9za and somran. Mostly laptop runs slow issue occurs due to broken Windows registry entries. Fixing registry will help you to boost up your laptop. You need to download and install a Registry Cleaner program to fix corrupt or broken registry entries. To download a reliable registry cleaner, go to famous website download.cnet and search there Reginout. Which I personally use and recommend the friends. After downloading run all of its tools one by one except Internet Optimizer, to clean all the junks and registry errors from your computer.

  • Photoshop CS6 Running Slow After GPU/RAM/CPU Upgrade?

    Hi all,
    I recently upgraded my Mac Pro 1,1 with the following:
    CPU Upgrade to 2 x 2.66GHz Quad Core
    RAM Upgrade to 14GB
    GFX Upgrade to ATI Radeon HD 5770 1024mb VRAM
    Everything seems fine. My temperatures are normal and things are seemingly speedy.
    My problem is that Photoshop CS6 seems to run a little slow. I'm only working on web files (72dpi) that are yes, sometimes quite long in length (5000px high), but that has never been an issue.
    Some problems I've noticed:
    When I click to edit text, it may take 2 seconds before I can start editing it
    When I scroll upwards it chugs a little
    If I grab an object/shape and drag it around too quick, it might lag a little
    I'm not sure how to explain it really, but for the couple hundred dollars I spent on upgrading my maching, I wouldn't expect any of these things to be an issue.
    Here are my photoshop performance settings:
    Any suggestions would help. No trolls please.

    Something to try:  Reset Photoshop's preferences to defaults.
    Press and hold Command - Shift - Option immediately upon cold-starting Photoshop.  If you get the keys down quickly enough - and you have to be very quick - you'll get a prompt asking you to confirm deleting your current preferences.  Once you confirm that, Photoshop will start up with a default set of parameters, though you will still find you can select your named workspaces and (I believe) your Actions will all still be there.
    Try immediately to see if the problem recurs.  Then methodically make your preferred preferences changes, quit Photoshop, and restart, then test to see that the problem hasn't recurred.
    With some luck, you'll have cleared up the sluggishness, and will have been able to make all your preferences changes you like without it recurring.
    This really can work.

  • Mac Book Pro runs slow after Lion 7.2 upgrade

    Ever since I downloaded the Lion 10.7.2 my MBook Pro runs SLOW! Any thoughts or suggestions?

    Reinstall preferably from scratch:
    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
