iPhone 4 RUNNING SLOW/WHY/HELP

Same thing here. Been living with this for a little while now.

All iPhones are subject to slow downs if not maintained. After you read the troubleshooting section of the User Guide, which of the steps described there did you try before posting?

Restart phone
Reset phone
Restore in iTunes using a backup
Restore in iTunes as new, without using a backup

Restart phone - CHECK
Reset phone - CHECK
Restore in iTunes using a backup - CHECK
Restore in iTunes as new, without using a backup - NOPE

Settings > General > Reset > Reset All Settings
Restore as new
Go to Apple Store Genius Bar for warranty service

So Modular747, your diagnosis is that the iPhone and all its services and third party applications are perfect and if it's found not to be operating absolutely perfectly just return it for service?

I'd appreciate an understanding as to WHY the iPhone could be running slower and perhaps how to repair it and avoid the issue in the future (with said repaired iPhone from the Genius Bar).

My Phone has been laggy after 4.3 update...

I read when putting phone on Airplane Mode it goes back to speedy Gonzalez way...

Anyway I hope Apple Can get a new more reliable iOS very soon so we can all be happy again with our expensive devices.

No, if you read what I said, troubleshoot your phone. if you get to the final step, restoring as new, and that doesn't help, there certainly is a hardware problem that needs warranty service.

Usually it's low memory state with an open loop process running in the background. Usually closing "recent opened" apps and resetting takes care of it. Sometimes there are corrupted data and settings and you need to restore as new. Not all that rarely, hacked downgrading the iOS, jailbreaking or attempting to do so tanks the phone.

99.99999999999% of those who updated don't have this problem. It's not the iOS. Fix your phone.

If you're not happy with it, return it and get a cheaper phone. Otherwise, report it to Apple, and wait patiently for the updates.

Well the same thing happens every year. They release an 'Update' which slows everything down, so you'll have to buy the new model.

Maybe it's a dumb idea having one iOS for all mobile devices. It seems that the latest iOS releases are geared for more powerful devices, (next release), NOT the ones we actually have.

restoring as new doesnt work. just as slow as before
