I am sure all iPhone users are happy to see the latest Firmware update from Apple – OS3.0.  Because they get the most wanted feature – Cut, Copy, Paste and many more enhancements including Push notifications.  Find out 40 awesome iPhone 3.0 features you can expect from this upgrade.
And most probably, everyone owning an iPhone might have already upgraded it to 3.0 using iTunes.  If not, then I suggest you do it today.

As always not everything comes wrapped into a gift package for you.  All good things comes with some problems too.  That’s true for iPhone 3.0 update too.
A lot of people (including me) are reporting that the after iPhone 3.0 upgrade, they are seeing significant battery life drop, more apps crashing and some apps even fail to load at all.  They are also reporting that the overall response time of iPhone has reduced drastically.  Page refresh takes longer than expected and apps take more time than ever to even load.  Even the phone seems to be hot all the time.

Everything is sluggish after the upgrade: scrolling, the home screen, and especially 3d games, the frame rate gets terribly choppy. This never happened before with 2.2.1. I’ve restarted the phone, restored it in iTunes, nothing seems to help.
I’ve unchecked everything under Settings > General > Search Results thinking it could be a Spotlight indexing problem, but it hasn’t made a difference. This is maddening, hope someone figures this out soon!

If you are also among those people, then don’t worry, you are not alone.  And be happy, I have found a solution which worked for me.  Most probably will work for you too.
One thing before you start following this guide, please understand, this method may or may not work for you.  But be assured you are not going to lose anything even if it doesn’t work out for you.  Though in any case, please follow this guide on you own risk, I am not responsible if anything goes wrong.
Frankly speaking, the culprit in most of the cases is ‘Push Notification’.
There are various workarounds and involves many steps of testing to see what exactly is the culprit in your case.
Method 1:
Try disabling ‘Notification’ under ‘Settings’.  It has been reported that this step has helped some people.

Method 2:
This step can be combined along with Method 1.  Try disabling ‘Fetch New Data’ under ‘Settings –> Mail, Contacts, Calendars’ to OFF.  That has also helped some people.

Note for Jailbreakers and Unlockers of iPhone:  If you are among those people who have unlocked your iPhone to use it with T-Mobile.  And if you are not subscribed to any data plan, then please understand ‘Push Notification’ doesn’t make any sense to you.  So just go ahead and disable it right away. (explained later)
Why? Because if you don’t have any data plan, your iPhone keeps trying to connect to the Push server and drains the battery.  If you are not subscribed to any data plan then ‘Push Notification’ doesn’t even makes sense, because you are not connect to internet all the time.

If it doesn’t help, then go ahead and follow rest of the guide.
Method 3:
This method involves connecting iPhone to iTunes on your computer and resetting it to factory settings.  Please follow the rest of the article very carefully:
AT&T Subscribers:

1. Restart your computer and iPhone before going to the next step.  (This is to make sure no background process is running on any device.)
2. Open iTunes on your computer.
3. Connect your iPhone to computer using USB cable came with your iPhone.
4. Once iTunes recognizes your iPhone, right-click on the phone and select ‘Back-up iPhone’.  (This is to make sure your iPhone is properly backed-up and you don’t loose any app and data from your device.)
5. Once the back up is complete, go to the iPhone ‘Info’ tab in iTunes as shown below.
6. Click ‘Restore’ to restore your iPhone to its Factory settings.
7. Follow on screen prompts to complete the process.
8. Once the process is complete, disconnect iPhone from your computer.
9. Check if everything works fine.  If it works then you should see a message to update it again to 3.0 in the Info tab mentioned above.
10. Update by following on screen prompts.
11. Re-sync your iPhone by restoring your old profile.  This old profile was created in step 4.AT&T users please skip rest of the points mentioned below as they are written for T-Mobile users and those who want to use iPhone by unlocking it.Other than AT&T subscribers:
12. If you are going to use T-Mobile by Jailbreaking and unlocking it.  Then nothing would seems to work right now as it is not unlocked yet.  You won’t be able to make any calls or anything.
13. So now the first step is to Jailbreak it so that it at least works as an iPod Touch. Follow the steps mentioned in this post and then come back here.
14. Follow Method 1 and 2 to save on battery life.
15. Your iPhone should be running faster now.  Apps will be launching and running smoothly and hopefully they won’t be crashing any more.

I was able to sort out the battery problem by following the above mentioned process, which is basically to restore and reinstall only.  But it works and hopefully will work for you too.  Everyone seems to report various results, but restoring and reinstalling has helped most of us.
There is something really wrong with OS3.0 update ‘Push Notification’ which causes the battery to drain very fast.  Hopefully we will see a 3.0.1 update from Apple soon to resolve this issue.
If you want to see the responses and problems other people are facing, please head over to Apple Discussion thread.
Please drop in your comments below to let me know if any method worked for you or if you are seeing any more problems.  And if this article solved your problem then a little appreciation by sharing this post on Digg, Stumble, Facebook and Twitter etc wouldn’t hurt anyone.  Will it…???
