iPhone 3G w/ OS 3.1 - Problems (Slow operation)

I have the same problem. I upgraded to the 3.1 OS from 3.0.1. My iPhone 3G is not unlocked or jailbroken. After the update, the phone's functionality slowed severely. Pressing the home button, side scrolling to other home screens, placing calls, and internet connectivity all were severely slowed down.

I have iTunes 9.0 installed on a Mac Mini with Snow Leopard 10.6.1

I then, restored the phone using the iPhone restore option and then restored using last saved backup. No improvement.

I then decided to restore to full factory settings again and setup the phone as new. Some improvement noted, but as soon as I started installing apps again the slow response (in all the aspects above), returned.

I have one of the (recently removed) free memory apps, MemoryInfo, and it seems the phone on its idle state is using above 95% of the total memory. I did also notice severe battery usage, after just 2hrs of idling the phone the battery drained to 65%.

Apple Engineers - If you do read this, please issue a patch for OS 3.1 or allow us to downgrade to OS 3.0.1 until this problem is resolved.

Thank you.

Possible Fix. 3.1 starts syncing subscribed calendars through mobile me. I turned off mobile me calendar syncing, and deleted all my calendars, after 5 minutes of testing my iphone feels much better.

I noticed that mobile me wanted to add 3000+ events to my iCal this was the first sign for me that some thing was wrong with the calendars. Loading cal app on the iphone crashed the phone every time.



Thanks. That worked for me as well. I switched off any synch with Mobile Me and now, it's back to normal speed ;))

To add to the Chorus

Same problem here, with a wipe and restore from backup there was no difference then after a full restore, the issue persisted. This is definitely an issues with 3.1, and switching off functionality, such as mobile me syncing, defeats the whole point of having an iPhone!

Come on Apple

3.1.1 NOW PLEASE

These are the steps I have taken to minimize the problem:
1. Disable WiFi and Bluetooth
2. Disable Push Notifications
3. Change email Push to manually.
4. Removed all but essential apps (two full home screens incl default apps)

Mitigation steps taken:
1. Restore iPhone to full factory settings (3 times so far) using iTunes 9 (I have a Mac Mini with Snow Leopard 10.6.1) = NO CHANGE!
2. Revert back to iPhone OS 3.0.1 = iTunes returns error 1035.

Monitoring:
1. Noticed battery drain to be 1% every 10 to 15 min with the recommendations above.
2. Noticed memory usage: Wired ~27MB, Active: ~18MB, Inactive: ~10MB, Free: ~2MB using MemoryInfo App. This is just idling, with the recommendations above.

I hope this helps, us Apple paid customers, and the Apple engineers to help us Apple paid customers.

We purchased two new 3GS iphones several days before the 3.1 update. I am having problems with mine and my wife's 3GS iPhone sending text messages and emails... it seems that it wants to hang up after sending the message, with the progress bar getting almost to the end and stopping... it times out and doesn't send. This is with full 3G signal, when we had no problems before the update.

Thanks for beta testing on us Apple!

A followup: Went to an Apple Store today to request a OS downgrade. The store "Genius" and his manager profoundly refused to do downgrade as it was against company policy because it might render the iPhone useless (error 1016). If it wasn't useless already.

They offered to replace the iPhone, but I had to shed $199 plus tax because the iPhone is out of warranty.

They did however did a full restore at the store. This is the 4th full factory restore. The logic behind it was that the copy of the upgrade in my computer was corrupted.

After I left the store the battery life was around 45% - when I got home 30min later the iPhone's battery was less than 10%. I am loading the music, apps and rest from scratch again (4th time).

MY SOLUTION TO THE PROBLEM !

Well, actually not my solution, but miahill9's solution, which just works fine.
Of course, it's rather a workaround 'til Apple got it's 3.1.1 out to us.

1. Go to you Mobile Me account on your iPhone.
2. Switch off, all services.
3. You're done. That's it. Everything is smooth and fast now again

(As a matter of fact, I believe, the Calendar push service might be the problem, as it tried to sync calenders with my iPhone, which I even didn't know ('no credentials for calendar xyz...')

So, that explains, why it starts OK, after a reset for some seconds only, and than starts pulling thousands of sync data. Slows down (as this is one of the few background tasks) and kind of stucks.

Try it out, as a work around, it's great.

Thanks again to miahill9.

Hi nimo,

I am glad you fixed the problem this way. On my device it does not work.

Somehow I am glad it did not, I would throw all my Apple product in the garbage if I notice that an Apple service (mobile me) is not working on an Apple SW (iPhone 3v1) and HW (iPhone 3G).

I cannot take as serious all the "tricks" I read in this forum such as "I removed all the apps" or " ...all the song".
This is buggy firmware, no doubt. Now Apple has to give us the solution by releasing a patch correcting the bugs or allowing customer to downgrade in iTunes; it is obvious that customers cannot do anything to bypass the bugware Apple dared release without proper tests.

Cheers

Battery consumption and performance
I too am having the issuse described in this thread. I have changed NOTHING on my iPhone 3G, other than upgrading from 3.01 to 3.1.
- battery drains incredibly fast while in idle mode; worse if in use. (lasts 3 hours in idle mode, used to last 20-30 hours)
- performance is sluggish. Sometimes a call comes in and the screen wont activate until the last ring, at which point my call goes to voxmail. This is new behavior

Oddly, my COO went through the same upgrade this week and sings the virtues of the upgrade (performance and battery life).

Wisdom of crowd......

Thats the only explanation, why no one from the Apple team shows up here and at least gives a comment like '..we are working to fix this problem...'

So, leave the crowd alone, and eventually, someone is gonna fix the problem.

From an investors point of view, nice cost cutting.... from a client perspective, you guys did do better in the past.

I'm wondering, whether Steve's iPhone is slow as well.... or maybe he is using a Nokia instead ;)))

My iPhone is not usable since 3.0 It's slow as ****.
I waited for the 3.1 to fix the problem before complaining, but now surfing the web is simply IMPOSSIBLE. Safari.App rarely responds to touch, and when it does it simply interprets a scroll as a single touch and jumps to a new page.
I have rarely seen such a bad device in my life.

There is no way to get anything running at acceptable speed. Messages.app takes for ever to load... etc...

Even the phone.app gets slow as **** when scrolling in the contacts. It's incredible. The phone doesn't even ring when I get phone calls I just get notified by SMS that I missed a call with no trace of the missed call in phone.app. Can't call people, the phone takes for ever to give a tone when a number is called (sometimes it takes over a minute to react).
Bluetooth is crippled and there is no way to change songs from BT Headphones...

This device is a pile of steaming crap. It's not the first time I have problems with an Apple device. but I never had such a terrible experience before.

Well...I've had an iPhone 3GS for only about 2 weeks. I have one profile change to use Tethering. And it has been plastered all over the Internet to take a wait and see attitude towards OS3.1 upgrade.

The benefits were simply too small to rush into an upgrade. I actually found this site when I did a search on iPhone OS3.1 problems.

Not blaming the users by any means - it sounds like it is a bad update - but heck, isn't it prudent to do a basic google search before updating your phone with a 243MB new OS?

From what I hear, I will pass on this upgrade. I find my 3GS with 3.01 to be very stable and perform very well. Best smart phone I ever had - only the keyboardless typing being a challenge.

So bottom line - if there is no compelling reason to upgrade - then don't. If there is a compelling reason to upgrade, then research before doing so.

Now Apple - fix 3.1. Soon.
