Hi James, glad that that worked for you. I managed to solve my battery problem without setting up the iPhone from a fresh install though so YMMV.

I’ve seen this problem a few times and I dont think it has anything to do with notifications or push being activated. For some reason if you’ve upgraded from 2.x to 3.x and chose to restore your iPhone from a back up instead of a fresh install the batterey problem seems to pop up. I had the same issue and all I had to do was back up my contacts then restore the iphone, then when it asks if you would like to set up as a new iphone chooses that option. This will also resolve the youtube issue if you are using t-mobile and your youtube cant connect to the server.

I had the exact same issue. I too blamed my jailbreak. I had figured that it was something like SBSettings churning the CPU. I re-jailbroke my iPhone (3G) but did not install any Cydia apps.

At around the same time, for different reasons (auto-lock issue), I reset my mail settings.

I no longer have the battery issue.

I might even work up the nerve to install SBSettings later today…

Me too! I’ve been hearing complaints though that battery life actually got worse for most non-iPhone 3G S owners. I guess it varies.

Good news for me is that I’m getting an iPhone 3G S of my own when it comes out in Singapore.

mm, on my side, I was/am under the impression I got a better battery life after the upgrade to 3.0
