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.
