Slow iPhone 3G after iOS 4

Why is my 3G so slow?????????? I updated to 4.0 and my 3G has been having issues ever since. I really cant stand it! the rotation takes like 5 seconds, switching home screens is jumpy, the iPod crashes if you use the purchased link in the iTunes app. Folders open and close slowly, and when I lock it the lock noise plays then it plays like 3 more times. Settings also crashes!!!

is anyone else having these problems? Im really confused. It didn't do this with 3.1. I've also never done anything like jail breaking it....

I've tried restarting but nothing works, any help, Is it time for a 3GS?

Macbook Late '07, iPhone 3G, Mac OS X (10.6.3)

Mine is not only slow: it also crashes.
I have also made the mistake of updating my iPhone 3G to iOS4. I thought I'd be finally able to use the camera to record movies, not just pictures (BTW: Apple focused on "multitask" and such, but nothing about the ability to use the camera for recording movies, so it was just a [bad] guess from me, and the "multitasking" isn't even available for 3G).
Anyway, I'm experiencing the same speed issues, but with additional hangs. The main problem I have, additionally to the slowness, is the iPod playback: when I do something else with the iPhone (e.g opening another application while the iPod is playing) the music jerks. If I do this too much (e.g playing a cards game while listening to music) the music finally stops (after jerking very much) and, sometimes, the current application (e.g the game) crashes (like a force quit). I then quit the game, launch the iPod again and see the "current" music, with the position at 0:00 and the "play arrow" (so the playback has reset) and, in "random list mode", the track has been set to the first one (1/x).

I have read the first 2 pages and the last 3 in this thread, because 19 pages is really huge. But I haven't seen anyone talking about this kind of hang, thus my reply.

BTW: anyone knows "why" this slowdown actually occurs? My guess is about the new "multitask" feature. Some have also telling Spotlight is the culprit, but I have tried disabling it and it's not better now.

For statistics, I had the same problem, from the first day iOS 4 was released until today.

I just performed the restore in iTunes, and marked as a fresh install, not a backup restore. I am very surprised and happy that my iPhone 3G is now fast as it was before, even using iOS 4. In fact, the process upgraded from 4.01 to 4.02, but I don't think it is related with the "new" sub-version, but instead with the restore process.

My phone 3G became really really slow on the OS4 upgrade until I updated it just recently to I think it's 4.02? but it's still slow and now I have new problems. Now the battery shows full all the time, like it's no longer working. I can't tell how much battery I have until it's too late. And I notice it takes forever for it to wake up when I press the "action" button. Ugh, I want to go back to the 3.XX OS...how do I do this?

Dude, I totally understand everyone's frustration. I was frustrated too. All I'm trying to say is that there is a "solution" which is to downgrade and in this forum there are all the resources for doing it.

Now, about the complaining thing, if you REALLY want to be heard by apple, instead of complaining here in the forums which are for users, just send Apple some feedback:

http://www.apple.com/feedback/iphone.html

Now in that one you can get all your rage out! then you'll be heard. Not in the discussions section, man. The discussions are for helping each other with issues. And the "solution" is already here.

Peace

This is not a supported solution, and I don't want to risk any kind of rouge software on my phone. I'm glad it worked for you, but please remember, this is not a solution for all.

I have already submitted feedback.

Posting in this forum helps people by allowing them to read the problems that people are having with the 3G and iOS4. It also allows people to share any possible solutions - such as the one that you suggest (rolling back to 3.x).

Again, your solution is one way to fix the problem, but it's not for everyone.

Aug 24, 2010 8:29 PM in response to DCIFRTHS

Dude, nothing is going to happen to your iPhone. It's just a rollback in the OS.

Downgrading is the solution for when after 3 weeks of dealing with a phone that doesn't work properly, you decide to go back to where there was no problem. Do you know what that is? Answer: OS 3.1.3

Why forcing your 3G to deal with iOS4 when the only "benefit" you get is folders and united email inboxes?

If you are in such a hurry to have iOS4, then upgrade your iPhone to at least a 3Gs and then you'll really take advantage to all the features of iOS4.

If you were happy with your 3G and want to keep on smiling at it every morning, then downgrade and wait until apple really come out with a solution... if it does.

Peace!

i think anyone that says they're not having any performance issues with the 4.0 update on a 3G is a McApple mole...literally everyone i know, including myself, that has updated their iphone 3g has had the same/similar problems that you have. And the people i know that haven't updated to 4.0 on the 3g have much faster phones than the ones with the updates...and we compared file sizes-music, apps, free space, etc and for the most part they were similar, but the 3Gs that didn't update were much, much, much, very much faster than any of us with the 4.0 update.
Moreover, the people i know with the 3GS that updated have not had the same problems.

Aug 24, 2010 11:04 PM in response to des3134

I am having the same problem. I tried to go back to 3.1.3 firmware which is stored in my itunes folder and it got all the way to the end of downgrading my phone and at the very end 'error' I did some research and evidently apple has to sign off on me downgrading my phone on my computer!!!! Very frustrated with how slow the 3G is on 4.0.2 Please Please Please allow faithful users to downgrade. I have a 2G and a 3G and have bought many many apple products.

Aug 24, 2010 11:08 PM in response to qwertyfreak

I am having the same problem others are having with my 3G on 4.0.2. The phone is virtually useless and I have tried restoring it. I tried to go back to 3.1.3 firmware which is stored in my itunes folder and it got all the way to the end of downgrading my phone and at the very end 'error' I did some research and evidently apple has to sign off on me downgrading my phone on my computer!!!! Very frustrated with how slow the 3G is on 4.0.2 Please Please Please allow faithful users to downgrade. I have a 2G and a 3G and have bought many many apple products. I have 9 long months left on my contract and I am seriously considering bailing and paying the early termination fee just to get out of feeling like a prisoner who is not allowed to downgrade back to a OS that acutally worked for me. Very frustrating.

Hi, my 3G was almost useless after the 4.02 update, endlessly hanging between screens, etc, as listed on this forum. I went looking for other forums and found an amazing solution. My phone now works as it did with 3.1. I wish I could remember where I found this workaround so that I could give credit where it is due. And, I hope it works for you all, as it did for me.

(1) Go to "Settings", "General"
(2) Select, "Home Button"
(3) Select, "Spotlight Search"
(4) De-select, by touching, ALL choices (i.e. "Contacts" down to "Messages"
(5) Power down the phone (Hold the top button and the Home button together until invited to use the slide to power down)
(6) Power up by holding down the top button until the Apple icon appears, etc
(7) Go back to the Spotlight preferences and select all choices again, if you wish.

When you go back to your home screen again you should have your 3G back to its perky best. Apparently the constant Spotlight indexing is the main problem if you upgrade without this re-set
I hope it works for you, as I find the bonus of using the features of 4.02, as far as the 3G can use them, is attractive, and the speed is back. Good luck.

I take huge exception to your comment Not Yours.

I've got an Apple iPhone 3G. I updated it to OS4. It went VERY bad like everyone is saying. I fixed it somehow. I am livid with Apple for not fixing it for me. I am livid with Apple for continuing to allow users to update. I am livid with Apple for their two month silence on the issue.

I have complained to Apple several times in the correct way here: http://www.apple.com/feedback/iphone.html

How does this make me a 'McApple mole'?

The 3G most definitely CAN run OS4.0.0/4.0.1/4.0.2 because it is categorically running just fine for me now. Why on earth would I make this up?

This forum isn't here to flame Apple or to flame each other - it's here for users to try and help each other.

If you just want to (quite rightly) complain to Apple then do so here: http://www.apple.com/feedback/iphone.html

I updated my iPhone 3G the day that OS4 came out. I fixed it WEEKS ago. I've posted a few details to try to help others get their iPhones working well again until Apple release an official (and long overdue) fix. The best written example of how I went about fixing mine was recorded by highdef.

If you have a slow iPhone then read my thoughts here: http://discussions.apple.com/post!reply.jspa?messageID=12128733

Then follow highdef 's process here: http://discussions.apple.com/message.jspa?messageID=12078619#12078619

The spotlight suggestion that others have posted is also well worth doing.

If you try the fix do post back with whether it worked for you or not. If it does then great - your fellow users have helped, you've got a working iPhone again, and maybe others will fix theirs too.

If it doesn't work then complain to Apple here: http://www.apple.com/feedback/iphone.html

If you don't want to try the fix then leave those alone who are trying to help but do complain to Apple here: http://www.apple.com/feedback/iphone.html

'McApple mole'... I ask you...
