Try restoring your iPhone with iTunes from your iPhone's backup.
If no change after that, try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup. If there is a problem with your iPhone's backup, restoring your iPhone from your iPhone's backup will also restore the problem.
i have the same problems after update to3.1
provider T-Mobile, Austria
phone response is very slow. loses connection after calls and often fails data connection too.
and suddenly shut down.
after 3.1 update,removed some applications which blocked wifi signal.now i can connect to my router easily if i'm close to it.
therefore updating to 3.1 weakened my wifi reception.
should i do a full restore to get back full wifi strength ?
thanks
Hey guys, can we keep the petty squabling down for one second and get back to the point.
Yes it is a good idea to restore your phone, but it would be even better to restore to 3.0, firstly sync your iPhone and back it up. Then ctrl click restore so that you can select the firmware to install on the iPod, find your iTunes firmware folder (usually in the library) and find iPhone 3.0.
Once you have found it restore with that, the restore from backup and you will keep your stuff and be on 3.0
I didn't upgrade to 3.1 until this weekend after the ATT carrier update came out. Before that I was running 3.01. All I can say is YIKES! My iPhone got very slow. Had trouble answering calls. The slide to unlock was very slow.
Very frustrating.
I have two phones like this. I compared and contrasted the two. One common issue: both had the Facebook app installed. I removed it, did a hard reset. With the phone off held the sleep/wake button for 10 seconds. (the apple logo appears, then the screen goes blank, then the logo appears again).
My iPhone also got painfully slow after "upgrading" to 3.1. I tried removing some applications, starting with Facebook, and it got noticeably faster as I nixed useless app after useless app. Maybe my 8GB iPhone 3G was memory-challenged. Just a thought.
ok so my moms phone has been having the same problems as all of yours. I took it to apple, here is what they told me to do
make sure you SYNC all of your contacts, apps, calendar, notes ect to your itunes, if you have more than one iphone account on an itunes create a new user (this is for mac users) and do this on the itunes under a different user. Setup phone as new, and re-sync your stuff back on to it. DO NOT USE THE BACKUP, due to the way the iphones hardware works, it will save the "bad habits" such as app crashes and horrid battery life and many other problems into the backup as well as your data, causing it to do the same things it did before a restore from backup.
Everybody having problems with battery life, remember to delete your email accounts, turn your phone off then on, and re-enter them. This helped my battery tremendously. This is what we had to do for the 2.0 software and it worked.
I have had VERY slow performance on my iPhone since upgrading to 3.1. I tried restoring, removing all applications, etc until I was able to isolate the problem.
For myself, deleting my Mobile Me account instantly allowed my phone to operate at full speed again. It is aggravating however, to go without Mobile Me which I am paying for, but having a working phone at this point is my number one priority.
I'm curious if deleting a Mobile Me account improves other's performance issues with 3.1
I spoke too soon about the effects of erasing and starting anew
Erasing and starting as a new phone, and reimporting all my apps, contacts, and so on from itunes worked perfectly for a while. I then noticed however that I wasn't syncing Mobile Me over the air. So I went into the iphone/preferences and switched on syn calendars, contacts, bookmarks, and Find my phone. Instantly performance was degraded and battery life plummeted.
After a few days I turned these off on the phone (this took me some time; the process was slow and didn't work every time) and hey presto, it now works fine. So it isn't Mobile Me that causes the problems as such, but syncing over the air - at least for me. And I don't know whether it's contacts, calendars, or Find my phone, or all of them, that causes the problem.
Updated to 3.1.2 , WIFI strength is back to normal.I can connect easily to my router . IT FIXED MY WIRELESS CONNECTIVITY (as before the upgrade to 3.0).
I have been effected by battery issues since 3.1 so I updated to 3.1.2, in the hope that it might make a difference.
Last night I charged my phone to 100% at 7pm left it unplugged but still connected to a wifi network. When I checked it at 7am the phone was off – no battery charge.
The update seemed to make it worse. Has anyone else had this experience?
