Iphone 4 slow after IOS 8 upgrade

I've upgraded my phone to IOS 8.0.2 and I've noticed a substantial decrease in both performance and ability to use SIRI. Apps load incredibility slow and SIRI is painfully slow. At least 8 seconds to load, and then another 8 to 10 to get the app or SIRI to do anything. I've closed all the background applications and restarted the phone to no avail. Can someone tell me why there is such a performance hit to the IP4?

That's the answer? Really? Downgrade? Are you kidding me?

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.

JBL Radial dock no longer works on iPhone 4 after iOS 5 upgrade.

JBL Radial dock no longer charges my iPhone 4 after iOS 5 upgrade however I still Can play music.
Any help on that ?

OK a bit of success over the weekend. Not sure if it will help you guys. So i have an IPHONE 3gs and it would not play any music through the JBL but it would ring (through the JBL speaker) and charge while connected.
I sync'ed through itunes and made sure i had the latest version of both itunes and the IOS on the phone. Then pushed some podcasts and albums down from my computer to the iphone through the computer.
This must have sone something as now everythign works fine. all radio and music apps now play through the JBL.
Hope this helps.

IPads extremely slow after ios8 upgrade

Hello,
I own an iPad 2 and an iPad3 retina. Both were working fine until I upgraded them to ios8.
Since then, both ipads have slowed down to a crawl. Surfing the web is *much* slower, the ipad seems to hang when you simply load a webpage. Also, the keyboard has become so slow that it lags behind the typing. I will be typing a sentence, and when I stop typing, the ipad could still have 10 characters in the keyboard buffer.
So up until last week, I had a couple of ipads that were a little bit older, but still working at an acceptable speed. Today, I have two ipads that are frustratingly slow to operate.
So the obvious thing to do would have been to downgrade back to ios7. But unfortunately, this doesn't work either. I get a message that ios7 is not compatible with my device.
So can somebody offer a solution, either a trick to downgrade to ios7, or another method to get my ipads back to their former performance.
BTW: same problem on my iphone 5, much slower as well, but here the speed is still acceptable.

iPad 2 and iOS 8.0.2 Problems
For all iPad 2 owners, this is an important solution for you! These problems result from long-term use, continuous upgrades, corrupted files and various glitches that happen over this long term use. You just need to get your iPad 2 back to FACTORY FRESH CONDITION to start out clean!
Here's one person's solution which will help a lot of iPad 2 users!

Re: IPAD2 very slow after IOS 8 upgradein response to pacoKAS
SOLVED: IOS 8 Issues on iPad 2:
I just returned home from a visit to the Genius Bar. Like you and many others, when I upgraded my iPad 2 to IOS 8, it became practically unusable. It was VERY slow, lagged whenever trying to to do anything. Lots of screen freezes and apps spontaneously crashing. I was convinced that the processor on the iPad 2 just couldn't handle the new IOS and I went in to see about restoring to IOS 7.
Thankfully, I was hooked up with a very sharp guy at the bar. The problem is not with the OS, it is with it being an *upgraded* OS. He used the analogy of when you had an older Windows computer and how over time (and over upgrades), they just tended to get slower and slower because of all of the garbage that was carried forward in the upgrades. At those times (and if you've ever had a Windows computer, you get this), the only thing that would speed it up would be to wipe the machine and do a fresh install of the current OS and then reload your apps, and the viola, everything would be fast again. Well, it turns out that IOS can suffer the same problems.
THE FIX: FIRST, be sure you have a current iCloud backup of your device. Connect your iPad to a computer that has a clean fresh copy of IOS 8 on iTunes (this is best done with a computer other than the one that you sync your device to because you DO NOT want to restore it from a back up just yet). Ideally, if you do this at an Apple store you'll be assured of the right version there and someone to answer any questions you might have along the way. You then hold the power and home button down to hard-reset the device and continue to hold them down until it reboots into recovery mode. You then follow the instructions on the computer to reinstall the OS on the device (which wipes everything from it and then reinstalls a clean copy of it). Once this is done (which only takes about 15 minutes), your device will reboot and ask you to set it up. Answer the questions about language, location, etc. and continue until it asks you to log into your iTunes account. Once you do that, it will ask if you want to either 1) Set it up as a new device, 2) Restore from iCloud, or 3) Restore from iTunes. Choose (2), restore from iCloud. This will ensure that it brings down "clean" copies of all of your apps and preferences rather than the potentially corrupted ones that might reside in your iTunes backup. That's it! It will take a few hours depending on how much data and apps you have, but I am happy to report that my iPad 2 is now running IOS 8 and it's running as fast as it ever did when it was brand new!
To sum it up, this process 1) Wipes your device and the garbage causing your problems, 2) Loads a clean and bug-free version of IOS 8 to your device, and 3) restores your apps and data so that it looks just like it did before the wipe, with the exception that it works now! :-)
Note also that by following this process you don't have to go through the painful and laborious process of reloading all of your apps, data and/or settings. iCloud takes care of all of that for you.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

IHome no longer works with iPhone 4s after iOS 6.1 update.

My iHome no longer works with iPhone 4s after iOS 6.1 update. Prompts message 'This accessory is not supported by iPhone'. Has anyone come accross this and is there a fix?

Ring up iHome and ask them for a fix... And if they cant supply you with a fix... Then you should be entitled to a replacement or a upgrade, as firmware upgrades on your ios device should not affect audio products......

How can i increase battery life in my iphone 5 after ios7 upgrade

will apple fix this huge problem of half of battery life in my verizon iphone 5 after ios7 upgrade? or should i just go back to ios6?

all I can say is APPLE has no official way to go back to a previous version of OS X. Perhaps there are hacks, but I cant speak of them here. Also, that link was only given to you an hour ago, so give it more time to see if it helps with battery life until a more stable version of iOS 7 is released. Im not happy about the battery life either.

I bought a Sandisk Connect Media Drive, downloaded the app from iTunes. Before iOS 8, movies played fine. After iOS upgrade I can no longer play movies downloaded from iTunes to the media drive. Anyone else have a similar issue?

I bought a Sandisk Connect Media Drive, downloaded the app from iTunes. Before iOS 8, movies played fine. After iOS upgrade I can no longer play movies downloaded from iTunes to the media drive. Anyone else have a similar issue?

I checked with SanDisk's own online support and they indicate that they have notified Apple of the issue.
According to SanDisk, the problem lies with Apple not having the iOS 8 version of the Safari browser having DRM decoding enabled that the Media Drive relies upon to decode and play iTunes DRM titles. Non DRM encoded videos will play in the browser.
DRM audio is not effected as this is handled by the native iOS music app.
As of the date of this post SanDisk have not been given a timeframe by Apple for this issue to be resolved.
I hope that Apple resolves this issue quickly as I have a large collection of DRM video titles on a 128Mb memory card installed in the Media Drive that I am unable to view.

I have a 2010 Cadillac CTS that no longer works w/my iPhone 4 after iOS7 Upgrade.

I have a 2010 Cadillac CTS that no longer works w/my iPhone 4 after iOS7 Upgrade. Any suggestions? It worked well before the upgrade.

I'm sorry...my question was imprecise. When I said 'no longer works' I was referring to plugging the device into the USB and power jacks in the center console and then being able to play music through the radio and control the device from either the radio or the steering wheel buttons. The iPhone 4 I use for this purpose has no cellular service and has never been paired with the car. I have an iPhone 5 with cellular service that is paired with the car. I cannot test theiPhone 5 with the car because of the difference of connectors on the phone. :-( The iPhone 4, however, works fine in my wife's Hyundai Santa Fe.
Thanks, in advance!

My ical won't sync with iPhone 4 after IOS 6.0.1 update

My ical won't sync with iPhone 4 after IOS 6.0.1 update. The "sync calendars" option is no longer available after I installed this update. Any ideas???I have tried a few times to sync, and nothing has changed on my calendars. I have had so many troubles with this update. Grrr...

I tried the same but it did not worked. But, i got a solution. I accessed gmail on my laptop. Went to gmail settings. There is a option to add a device. A iPhone was already listed. I clicked Revoke to remove it. Then i clicked add new device and gave it iPhone name and a new 16-20 character password was geenrated. I used it to configure gmail on my Iphone and it worked beautifully. So glad i have been able to fix this. That password is a one time password to authenticate that device.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
        Part 1 of 8 done at … sec
        Part 8 of 8 done at … sec
        The results are on the Clipboard.
        Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it. Then go to the next step.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I may not agree with them.
