Why is my ipod touch becoming slow and unresponsive?

My ipod touch is starting to freeze a lot and just not do anything... why?

Try the following:
- A reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod.
If you still have the problem that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order

  • Why is my iPod touch getting slower and slower

    Please can anyone tell me why my iTouch is getting slower and slower?
    also why do we have to do so many updates?
    Can I go back to the original software for my ipod touch?
    sorry for so many questions but they are related

    - All I can say in this Apple forum is that downgrading the iOS is not supported by Apple.
    - Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
    - Restoring the iPod also helps

  • Why is Safari becoming slow and unresponsive?

    Ok - I have exactly the same problem.  I can run safari and use it.  After a short while it becomes slow and unresponsive.  When I quit I get the rainbow ball of death and the only way I can stop the application is to force quit.
    It is definitely linked to a particular network account as the guest account check above shows that it runs fine on another account.
    As I watch system memory in actvity monitor while I use safari the fhe following occurs:
    1.     free memory gets gradually used up to about 50%
    2.     Inactive memory gradually builds to about 50% of total
    3.     Then page in and page outs build massively and the swap file goes into overdrive
    I have 32GB memory on board but even so it doesn't take long for Safari to gobble it up.
    At the same time CPU % shows 90-100% and Real Mem sits around 15-18GB.
    By this stage the whole machine is slow and unresponsive as safari ***** up all its processor and memory resources.
    I have taken the following action:
    1.     reset safari using the reset process built into the app - no difference
    2.     deleted the preferences file - no difference
    3.     deleted the Library/cache file - no difference
    Thought about resetting NVRAM but decided that it wouldn't make much difference because it seems to be linked to a user.
    Any thoughts/suggestions on other actions I can take would be welcome.
    Are there other cache or preference files that I should be trashing.  Can I delete and reinstall safari?  I don't really want to have to go through the process of establishing a new user and rebuilding a reasonably substantial docs and photo library and set up.
    Help.
    <Re-Titled By Host>

    You forgot to mention what version of Safari you have, but:
    If Safari is getting very slow:
    (Presumably you regularly empty your Safari cache by deleting the following file:
    Home/Library/Caches/com.apple.Safari/cache.db
    and clear your History)
    Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security, (including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat ) and further independent information can be read here:
    http://reviews.cnet.com/8301-13727_7-57338784-263/free-dnscrypt-tool-enhances-ma c-web-security/?tag=mncol;txt
    and here:
    http://www.macworld.com/article/1146064/troubleshootdns.html?t=234
    If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
    208.67.222.222
    208.67.220.220
    (You can also enter them if you click on Advanced and then DNS)
    Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
    http://support.apple.com/kb/TS2296
    If your computer is part of a network:please refer to this page: http://www.opendns.com/start/best_practices/#your_network and follow the advice given.
    If you use a Router, make sure it has the latest firmware installed.
    One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x as is described here:
    http://support.apple.com/kb/TS3408?viewlocale=en_US
    You can cancel DNS pre-fetching by going to Terminal and typing:
    defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
    You have to restart Safari for it to take effect.
    If Safari seems to hang for ages:
    If you have a lot of tabs open and/or a lot of pages running Flash, Safari can sometimes 'hang', requiring a restart of Safari. This can often be inconvenient, and as it is rarely Safari itself that is hanging but merely one of its plug-ins, usually Flash, there is a way using Terminal to restart the plug-ins (without restarting Safari and losing your tabs) by quitting the WebPluginHost process:
    Open the Terminal from the Utilities folder in /Applications and type
    killall -9 WebKitPluginHost
    Note that this command kills all Safari plug-ins, not just Flash. All plug-ins should start back up when you reload the page.
    Then go back to Safari and refresh any pages that were using the Flash plug-in. This also fixes the Beachball of Death. Try this whenever Safari gets slow or freezes. The later versions of Flash 10.1 onwards appear to have improved the situation somewhat, but haven't completed eliminated it.
    For this and other reasons Apple switched their websites to HTML5 in January 2011:

  • Why does my ipod touch turn off and on when cropping pics

    why does my daughter's ipod touch power off and back on when she is cropping pictures? she has only had it about 5-6months - any suggestions other than the apple store? they weren't too helpful before with another ipod and it is a long drive

    Error 9
    This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

  • HT1414 My 4th gen iPod touch is slow and has a lot of lag time with the touch screen and home button. It's just slow. Its a 32 gb thats barly half way full and im very disappointed. what do i do?

    My 4th generation iPod touch is super slow and sometimes i have to click the home button multiple times before anything happens. Its up to date and is a 32 gb but barely half way full. My friends have the same kind as i do, and they have the same problem. Mine is a little over a year old and i'm VERY disappointed in something that i spent over $300 for. What am i supposed to do to make this peice of crap work like it's supposed to? I paid a lot of money for it and i expect it to work but the only thing i've heard so far is "turn it on and off." Yeah... cause that solves everything. Does anyone know how to help me?

    Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
    Also, sometimes restoring the iPod helps.

  • IPod Touch is slow and frequently can't be synched

    Ever since installing v3.0 software on my 2nd Gen iPod Touch (32GB) it has been slower. Additionally, 90% of the time I try to synch it to my Mac I get errors -- either that the iPod isn't recognized and must be restored, or that there is no file to synch it from.
    Also, the iPod frequently gets very hot -- if looking at if from the back, the bottom right of the back surface is usually hot -- I'm assuming this is where the CPU is?
    I've tried doing backups and restoring from scratch multiple times. Nothing seems to be working. Any ideas or solutions? Thanks!

    take it into the apple store they will eather fix it or replace it.

  • Why is my iPod Touch so slow on Verizon midi 4620L?

    I just got a Verizon mifi 4620L Jetpack hotspot thingy.
    I connect my MacBook Pro to it and get 17mbps or so download speeds, 3mbps or so going up.
    I connect my 3rd gen iPad to it and get about the same.
    But when I connect my 5th gen iPod Touch to it I rarely get download speed peaks higher than 2mbps and most of the time the avg comes out to be less than 1mbps according to the Speedtest.net app on the iOS devices.
    So, the iPad and MacBook Pro both work properly on the Verizon mifi hotspot and the iPod Touch doesn't. On all other networks I've tried the iPod Touch can support download speeds up to about 25mbps maybe even more. All these devices currently perform the same at home on the Comcast fed wifi network: very fast download speeds on them all with modest upload speeds. So I know there's nothing wrong with the iPod's wifi radios. There's just something quirky going on in how the iPod Touch and the Verizon mifi thing talk to one another because another thing that's strange: the iPod will download around 1mbps but then go up at about 10-12mbps. The exact opposite of what I would like except for those rare times I would actally like to send out a lot of photos quickly.
    Does anyone know what might cause this?
    Also, when I look at the connected devices as an admin the iPad's device name is recognized and listed but the iPod Touch remains named Unknown. Does this matter?
    I'm frustrated because the iPod Touch is what I would most like to use with the mifi!
    Any body come across this situation?

    Does the iPod connect to other networks OK?

  • Why is my iPod touch 4G charging and syncing more than just once even though I'm not unplugging the USB?

    Yesterday, I connected my iPod touch to my PC with the USB cable charger for my iPod touch 4th Generation. When I connect it, it will sync and back-up my iPod. Then it would say something like this "Sync Complete OK to disconnect." I didn't disconnect the USB or ANYTHING. After like 3 or 5 minutes, it would just sync and back-up my iPod again.. Then it would keep on doing that and after 4 or 5 times, it would finally stop. But, while I'm using my iPod and it's still charging through my PC, it keeps on making that noise when you connect your iPod to your PC/MAC to charge and when you disconnect your USB charger from your PC/MAC. It just makes that noise constantly.. Then, it will stop after a couple of minutes. This is really frustrating me. If someone could help, I would be glad and it will brighten my day. THANKS.

    - See:      
    iPod touch: Hardware troubleshooting
    - Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
    - Try another charging source
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - Restore from backup. See:                                 
    iOS: How to back up

  • Why does my iPod Touch 4G disconnect and reconnect continuously?

    Hey guys. Basically, I use a PC with Windows 7 and have done for a good couple of years now. However, until a couple of weeks ago, whenever I connect my iPod Touch 4G to my computer via USB cable, it connects for a split-second and then disconnects for another split-second, then reconnects and keeps recurring and wont stop until I unplug the iPod.
    I have had a look at the possible causes and here are my attempts to troubleshoot the problem:
    - I tried different cables (to no avail)
    - I tried other iPods (to no avail)
    - I tried another computer (worked on that one instantly)
    - Re-installed USB drivers (to no avail)
    - Re-installed iTunes (to no avail)
    The only thing I haven't tried is restoring, but my internet connection is terrible and updating the IOS would take AGES!
    It seems that this is a computer related issue specific to my PC but I cannot, for the life of me, think of a solution.
    Any help would be appreciated. Thanks
    Carl

    I've tried plugging it in to every USB port thats available (the ones in the back too). I'm pretty sure I've done everything but it still doesn't work
    Anyone got any more input??

  • Why does my ipod touch turn off and back on repeatedly

    I've recently just sync'd my iPod Touch and shortly thereafter, the unit turns on, the "Apple" symbol appears, but then about 8-10 seconds later the screen flashes and it turns off. About 8-10 seconds later, it turns on. This behavior cycles repeatedly without any effect from manipulation of the "Home" or "on/off" buttons. It also makes no difference if plugged in using the A/C connector.

    Error 9
    This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

  • Why is my ipod touch screen black and when i try to turn it on it won't turn on ?

    i was listening to my ipod last week and it went dead , so i plugged it in to my laptop to charge it & to download some songs , the icon that shows its charging didn't come up so i left it in for an our or 2 but my computer still detected the ipod & itunes came up straight away, so wen i went back to it it still wasn't charged so i tried to turn it on the screen went white for a few seconds and ten back to black , my ipod still won't come on. anyone ave any idea's?

    Sorry to hear that you're having problems. Tried a restore with iTunes? If not try it and it should work. If this does not work, take it to your local applestore as ths COULD (not saying it is definately) be a Hardware issue.
    Hope this helps, Let me know hoe you get on!

  • Why is my ipod touch 5g lagging and freezing in Safari?

    Especially when the webpage has pictures/photos/visuals/graphics, Safari lags and freezes hugely and is basically inoperable. I've tried resetting the device (holding home buttona and sleep button at same time until apple logo appears) but doesn't help. What's going on? I'm very dissapointed at Apple.

    Try:
    - Reset the iOS device. Nothing will be lost      
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Go to Settings>Safari and Dlete Cookies, Data and History
    - Reset all settings                            
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                               
    iOS: Back up and restore your iOS device with iCloud or iTunes

  • Mavericks 10.9.1. Freezes or trackpad becomes slow and unresponsive when viewing downloaded PDF files in Preview.Help!

    The earlier post was my first attempt at posting and had some typos. Repeated with typos corrected.
    I have a Macbook Pro Retina 13" Late 2013 with preinstalled Mavericks.I now have the 10.9.1 update. Almost from the time of purchase in Nov '13, I have been experiencing freezes and slow & unresponsive trackpad. I have more or less narrowed this symptom as happening when viewing downloaded PDF files. The only option is to force eject, if available or shut down. I spoke to Support as I thought it was a RAM issue and they told me that in Mavericks RAM showing almost full was normal as it uses RAM differently. They took me through some resets and cleaning up which has helped a little but freezing stll happens. This never happened with my Macbook AIr running Lion. Any suggestions?

    So a PDF file that you can view in Preview on your MBA causes your new MBP to lock up and/or slow down. Is this right? Also you say more or less narrowed down to PDFs with Preview but does the computer exhibit this behavior with other programs and if so under what conditions? And how much free hard drive space do you have?
    Viewing memory use in Mavericks is different than with previous versions of the OS. Today it looks like we need to pay attention to what Apple calls Memory Pressure which is gauged by the bar graph in Activity Monitor and to the Virtual Memory being used. When the memory pressure graph bar gets too high it turns red and that's bad news. Looking at how much memory is being used doesn't help - I have a 16GB computer and with almost nothing running it still shows something like 15.79GB used but the memory pressure graph is just a think green line. So unless you see the memory pressure bar turning red lets not worry about memory usage at the moment.
    If among the things AppleCare had you do was reinstall Mavericks then I recommend a trip to the Apple store - and take a problem PDF file with you to demonstrate.
