Slow iPhone 3G after 3.0 OS update

Hi out there. If you all want to do something about this you have to let apple know about your problems in a kind of massive way. I just filed in a feedback http://www.apple.com/feedback/ at there feedback page for the iPhone. Maybe if there are huge amounts of feedback on the laggy behaviour of the iPhone OS 3.0 according to the iPhone 3G, they will do something about it?? So go there, file a feedback.

I had the same lagging problem with apps taking an age to close and the messaging app running slow, I was going to do a full clean restore so did a reset all settings first and that seems to have solved the problem without a full restore.

Actually, you are right. I did notice that the battery is lasting less than it used to and as some have mentioned I also noticed that when charging the iPhone 3G it is getting hotter than usual. I have bluetooth OFF and I even put the Airplane mode ON when I don't need the phone to save some battery life. Do you think the battery needs replacement (it is not even 7 months since I bought the iPhone 3G) or is it something Apple has to fix in OS 3.0?

Well my iPhone is back to being as slow as before I restored it. Typing has gotten insanely slow and apps are lagging to launch once more. (Hard restarts don't solve anything; I do it three times a day and it doesn't help!!!)

ilikeappleproducts: I think the battery drainage is just due to your phone working extra hard to handle the more intensive OS. My phone is two months old and its battery drains faster too.

Looks like I'm going to have to hack my iPhone back to OS 2.X until Apple updates its 3.X to specifically improve iPhone 3G performance. This really blows.

I too can report many functions on my iPhone 3G working much more slowly than they did before I installed 3.0. There is a lot of chatter on the web about 3.0 being an effort on Apple's part to force 3G owners into purchasing the new 3GS but, for those of us who are not yet eligible to upgrade, the price is prohibitive and I think it would serve Apple well, from a PR standpoint, to figure out how to get the 3G back to its pre-3.0 speed. This just doesn't look good...

The first suggestion is to do a hard reset by holding down the home key and the on/off button at the same time. Turning the phone off once a day will also clear up any memory sap, especially for users who use a lot of apps throughout the day, and is recommended for everybody.

The next suggestion is to disable push notifications. When push is enabled, not just does it sap resources from the phone (making things just a touch slower), but it also saps battery life. An iPhone in 3G mode with push notification enabled won't have a long battery life, and if it's being used much, forget about it.

A final resort would be to reset all settings, which would require some time to rearrange apps, etc. and should only be necessary if all else fails.

Also, I would suspect that Apple is aware of these issues, and is working on an upgrade that will, hopefully, be available soon.

i dont know why people keep offering the same suggestions that dont work. i already did all of this as stated a couple of posts above.

HARD RESETS DON'T HELP!!!! NEITHER DOES RESTORE!!! the iphone 3g simply will not handle 3.0!!!

Can't get my iphone 3G to sync after 3.0 update. Any suggestions? I've upgraded itunes, rebooted, etc, etc, etc. Sync hangs up at "verifying phone" stage and never moves past it (left it hooked up to computer overnight - still no sync completion). HELP!!!!!

I too have noticed a slowdown on my phone. I have noticed that there's a lot less free memory available on my phone, and I tend to get a lot of "lowmemory" crash reports nowadays, which I never got before.


I guess I'll have to get an Iphone 3GS sigh

I have the same problem. The delay is so bad I can't even use the phone in an automated system (like a Credit Card auto attendant) because it takes 5 seconds to recognize my button clicks.

Seriously, apple dropped the ball on this one. It's terrible. I'm sure they're working on a fix, but it may take a month or two.

I was dealing with the same issues of slow or frozen apps and homescreens and tried all the remedies short of "reset all settings (although, I think setting up as a new phone during a fresh restore takes care of this) but nothing worked. It would start to slow down after one day of use. So, I reverted back to 2.2.1 and am glad I did. Hopefully, 3.1 will be the remedy!

I have the same problem. At least I think I do. It's hard to tell for sure
unless you put two iPhones together. One with and one without the update.
In any case, since the s in 3gs means speed, it is a good push in the upgrade direction.
I'm not saying apple did that on purpose. Just an observation

Doing the "Reset All Settings" worked for me. Really improved things quite a lot!

Mine is annoying slow as well. Keyboard seems to take forever to react

Mine has leveled off in its deterioration since the 3.0 software bug with respect to speed; it's now just very slow.
The new problem is that its rapidly heating up with just a 5 minute phone call, very hot to the touch.
