Fixed! iPhone 2.2 Upgrade Low Battery Life

As I mentioned a couple of days ago, after Ashley upgrade of her iPhone to 2.2 from 2.1, her battery started draining really quickly. Unfortunately, this was exactly the opposite of what most people found – an increase in battery life.

I needed to find a solution.

As I mentioned in the previous post, there were two possible issues that I had read about and needed to try. They were:

1. Microsoft ActiveSync / Exchange / Outlook integration
2. Reset and wipe the iPhone, reloading all data and settings.


Since starting over would be a pain, I started with removing the Microsoft ActiveSync configuration from the iPhone. I hoped that would stop the quick battery drain on her iPhone. But, after a day – Ashley noticed the discharge rate was still higher than it would be and getting only one full day on a charge was not acceptable.

I then started the process to delete all content and settings. A process that takes a couple of hours to complete, especially if you include restore and backup of your files and data, then the initial sync.

The good news? After two days Ashley’s iPhone’s battery is performing much better, even with the Microsoft ActiveSync being re-configured. It was my first time completely wiping and iPhone, and overall was a pretty good experience.

For those interested in more detail, here is the process.

1. Sync or create a backup of your iPhone data through iTunes on your PC.
2. Browse to the Settings menu on your iPhone.
3. Click on the General option on the settings Menu.

6. Click on the red button which says Erase iPhone. The small print says that this will delete all media and data, and reset all settings. This will take about an hour. First, check and make sure you have a backup of your iPhone data and settings. Second, it really does take at least an hour to complete. Do not start this process if you need to use your iPhone in the next couple of hours.

7. Once the erase is completed, connect your iPhone to iTunes again.
8. You will be given two options, one to restore a previous backup or another option to treat it like a new iPhone. Restore your backup here.

After the back is restored and the sync is complete, your iPhone is restored to the previous state, but you will have much longer life on the battery.

Good luck!

The battery will last even longer if your Brightness is set low. The Darker it is, The longer the life.
