[iPhone] iPhone with Exchange Possible Battery Fix

iphone on exchange server

My experience with Microsoft Exchange 2007 on the iPhone was an interesting one. I set up my hosted Exchange account from work to the phone, and noticed the battery rapidly draining. I was down to 20% by 6:00 PM. I knew Exchange would effect battery life because of constant syncing going on- but this was draining the battery at an unacceptable rate.

I decided to turn “Push” off for the sake of better battery-life.

After a week of using the account on “Fetch” I decided to do some digging on this issue online, and found out that users were noticing great improvement when re-setting up Exchange on their devices.

Turns out that iPhone 3.0 has a bug where certain setups would have the iPhone pull data non-stop, meaning the phone was working even in sleep mode. Add 3G, Wi-Fi, and Location Services to the mix and you have problems.

I thought, what the heck, so I gave it a shot.

I went into Settings > Mail, Contacts, Calenders > tapped on the Exchange account > and tapped “Delete Account”

I then went in and re-added the account using the settings from my Exchange host, and voila! My battery life improved by maybe over 50% than compared to before.

If you are on the same boat that I was in, you’ve got nothing to lose- since all your data is safely stored in the clouds. So give it a try and let us know your experiences in the comments section below.
