    My iPhone 4 hs performed flawless since launch day.

    In the past 2 weeks I have had some progressive issues.

    1. Battery drain. It seems to last half a day now. So I did the basic troubkle shooting looking for an app that was running, etc.

    2. Email weirdness. At first, AOL would NOT delete messages. Now many messages show the preview but say 'this email has no content'. I have to quit mail via multi taskign bar and reload. often.

    3. More email weirdness. Now my email has to be quit often, and half the time fails to launch.

    4. All clock alarms vanished. I had 14 different alarmprograms and all vanished.

    5. General sluggishness. Almost as bad as iPhone 3 with 4.0 OS. Bad stuff. Major delays for swipipng, scrolling, selecting.

    My initial trouble shooting included the following.

    1. Hard reboot. No effect.

    2. Reset Network settings. Seemed better for a day, but no lasting impact.

    3. Reset ALL settings. No effect.

    4. Back up and restore. I lost all folders, and many saved games, and wall paper. But same problems exist.

    I am on an exchange network, and have a mobile me, yahoo and AOL account. I know many others that in the past 10 days have had their iPhones get sluggish, and had mail problems. I am wondering if something on the email server end could have an impact on the over phone performance? I have upgraded a few apps, but not loaded any new ones.

    If it were just my phone I would think hardware. But I know many people who lost alarm settings the past few days. Many with iOS 4.1 sluggishness, etc.

    What is going on? Any ideads to fix? My last fix is to erase and manually add back everything. I hate to loose my remaining saves on games that don't carry over or have a cloud setting, but I may need to if this keeps up.

    I also have been have strange problems with my iPhone 4's exchange email, which has caused my battery to drain in close to 3 hours. If I delete the exchange accounts my battery performs like normal. I have already deleted them and put them back on and the problem starts again.

    The one thing that I have noticed it that, while in the email it shows that it is constantly connecting and getting mail. I don't remember ever seeing it before.

    I know its not a hardware issues because I went to Apple and they replaced my phone. I also talk with some co-workers (that use iPhone 4) that use the same company email (different accounts) and they aren't experiencing anything at all similar.

    Could there be a problem with my exchange account?

    I think it may be a strange Exchange implementation. I have deleted my Exchange and have other colleagues with the same phone and they do just fine. So it is still variable, but I feel linked with exchange.

    I have an iPhone 4 bought around launch time. For month it has worked flawlessly.

    About a month ago the trouble began.

    I got a lot less battery life, the phone was hot even when off and mail acted weird. For example, I have 8 accounts on the phone. 1 of them is exchange, 2 Mobile me, 2 Gmail, 2 Yahoo and an AOL. My previous phones never had a problem with this, nor did this phone at first.

    First mail symptom. It would jump out of the 'All Inboxes' and into the master account every few seconds. Annoying, but manageable.

    Outlook email woudl show the preview but fail to download message from server. Solution was to stop mail from multitasking, and restart it. It would work for a bit.

    I decided to cut my losses and I did a full restore and rebuilt my phone app by app. I did not use the back up. All was good for a week to 10 days. Then same issues. Plus now the speed and battery life.

    Every app has MASSIVE delay. Like worse than my 3G on iOS4 kind of sluggishness. Typing an email is impossible. Home button is nearly unresponsive. Battery life is hours. I unplug a full charge and never even turn on the screen and it is down to 88% in 2 hours.

    I did a reset all settings. Nothing worked. I did another full restore from scratch. Nothing.

    I do not think it is hardware as much as some sort of conflict. I do not ever run the location aware apps in the background, but I have downloaded a few new apps lately.

    My questions are has anyone else experienced similar issues? Is it possible for a bad app to cause corruption to the system? I thought Apple checked these things. I have never jail broken this phone. I am up to date on all apps and iOS.

    I will do another refresh and take it to the Appel store, but I suspect they will tell me it is a conflict of some sort. I did casually ask a few weeks ago and the Genius stated some games are known to do this.

    I do not want to jhave to go app by app and keep testing configurations like the old OS9 Conflict Catcher days, but I need my phone to work again.

    Other useful info:

    It is connected to myc ar via bluetooth, this is also super slow and laggy. I have tried airplane mode, turning off push, rebotting, resetting all, resetting network, turning off notifications, disabling email accounts, etc.

    The best performance I got was yesterday. With no Bluetooth, no Exchange email, no Push, manual check of mail, and no notifications, the battery lasted 4 hours and the phone was super sluggish still.

    Using Sys Info I have no out of place errant processes I can see:

    User memory 60 MB
    System 69
    Nice 77
    Inactive 223
    That is typical.

    CPU load, inactive about 52% when freshly rebooted. As for process, most seem 'normal' iphone iOS related. Things like Kernal_task, launchd, syslog, lockdownd, mediaserverd, locationd, fairplay.N90, SpringBoard, BTServer, notifyd, apsd, lsd, MobilePhone,iapd, securityd, MobileMail, ReportCrash.

    I am not sure if there are any other fixes I can do via iTunes or on the phone itself.

    Any thoughst anyone?

    I hate to be the bearer of bad news but sounds to me as as if a complete Restore and running it nekkid w/ only the bare minimum for sometime meaning don't restore yr backup) is your only option :(

    If it keeps on failing, well then you're prolly in for an exchange unit

    Agreed. I'm jailbroken on 4.1 and experience none of the issues you mentioned above. I have, on very rare occasions (maybe once or twice in the past 6 months), gotten the email message where it says that the message has no content. But that usually corrects itself after about an hour or so.

    I'm guessing there may be something corrupted on your phone which might be causing all the issues you're having. I'd suggest a full restore and setup the phone as new and start from scratch :( I know, it sucks but I think all of us have been at that point at least once in our iPhone lives.

    After this, if you are still having all these issues then you may just have a crap phone or something.
