I updated to iPhone 3.0 OS on my iPhone 3G last week and I am now getting terrible battery life.

Before the upgrade, the phone would easily last a whole day at work. Yesterday I had to recharge twice. One time I noticed the phone was burning hot while not in use.

I switched off push last night and I left the fully charged handset by my bed at 11:30pm and it was completely dead by 5:30am - this has never happened before.

I have now switched off WiFi and Location Services.

Does anyone have any other suggestions other than downgrading back to 2.1? Unfortunately I'm away from home for the next 6 weeks and I don't have access to my iMac that the phone is synced to.
