Slow iPhone 3G with iOS4? Just restore it!

June 30, 2010 · 14 Comments

Since I upgraded my iPhone 3G (not 3GS) to Apple's iOS4 it has been running slow, and that is to put it mildly. It has been so slow I barely wanted to use  the damn phone! 

Reading a thread in the Apple Discussion Forums, I realised, like most things, when you simply upgrade software there is a bunch of detritus left behind, so following the post, I simply reset the phone through iTunes to factory settings, once done, I went and upgraded my carrier info (which it prompts you to do) and then restored it from the backup (that I made earlier) 

Voila, it is now running pretty snappily again. Joy!

    You having any problems with WiFi connections? Since the upgrade my 3G has failed over to the 3G network after 10-15 seconds of trying to use the Wifi.

    my iPhone 3G Having the same problem too :(( .
    then I was download 'system' at iTunes ,

    >when the phone just restarted (there's no application u open after turn on your phone, only 'system' application), it say's :
    Memory (RAM) :116 MB
    Used Memory : 89 MB
    - wired : 26 MB
    - Active : 17 MB
    - Inactive : 12 MB
    - Free : 8 MB

    >then i tried to open iPod then i opened iBooks after i closed it all, i Opened again 'system'
    Memory (RAM) :116 MB
    Used Memory : 89 MB
    - wired : 26 MB
    - Active : 19 MB
    - Inactive : 10 MB
    - Free : 2 MB

    so i looked at Process tab at 'system' , "other running processes : iPod, iBooks" (all program that u closed it's still run)
    that's why it's make our iPhone 3G running slow..... :(

    so it's better back at os 3 again.......

    Hi Mark - I am having the same problem, so following your factory reset and subsequent backup restore which OS are you now running?
    Cheers

    When you reset you factory settings, will this remove all of your photos, bookmarks, ringtones and etc....on the phone?

    thanks
    Scott

    THat is why I backed it up first. remove the photos you have taken, synch them up , and the apps etc, then reset. and yes, it will remove everything it seems.

    HTH

    Thanks mark for your comments. My phone has aso been so slow especially text. When I open text a blank screen looks at me for nearly a minute.

    One thing though. When I upgraded iTunes kept saying could not restore

    For those that are interested, there is also this solution which essentially just has you do a cold reboot (hold SLEEP and HOME buttons until it powers off). The reboot has been reported to take up to several minutes, but after it is done the OS gets snappy again.

    I had my co-worker run it over the weekend on his iPhone 3G and it worked swell.

    This won't require you to restore to factory settings, and should clear the old dust making the upgrade much cleaner.

    I just did that cold reboot described above and it seems, in the few minutes I have been trying out the apps and actions that were unbareably slow, it is now firing on all cylinders now with and occasional missfire. I will follow up later if it goes back to the snails pace.

    Sorry but the moment i noticed the lag I turned everything off and when this did not work I did a factory restore. It just improved slightly for a few days and went back to being slowwwwww.

    It probably just cleared some memory temporarily and thats why you noticed the improvement.
    My nearly two year old Iphone 3G is now officially one of the worst phones I have had the displeasure of owning.

    A cold reboot only works far a few days then it's back to slow.

    I read on another site that if you disable the spotlight search it is supposed to be fast.
    I did it. A slight increase in speed, but barely noticable.
    I'll try the cold reboot

    Tried everything, restored, cold reboot, turned off spotlight. Still laggy as hell. My girlfriends is the same. Wish I'd not updated both.

    I did manage to cure my phone though. I hurled it really hard at a concrete wall on Friday and the screen smashed to pieces. I took it back to the 02 shop and claimed for a new one, which arrived today. This kind of hard reboot even upgrades it to a 3GS! Funny how they ship with OS 3.1.3. Lol. Speaks volumes to me.
