Is anyone using OS 3.0 (gold master copy) on their iPhones? I am, and it seems to be eating through battery whilst (apparently) doing nothing at all.

Vanilla restore, not jailbroken. Any thoughts?
 
I know what you mean. Mine's doing something similar. I've got push enabled but I'm barely getting a day where before I used to get two.

Maybe it's Apple's push notification service....
 
They did say in the original keynote that it would reduce battery by about 20% i belive was the number but it will reduce it, I never got two days from my iphone even on standby and I have had 9 3G's (with various build quality and screen issues) all had the same battery life of 1.5 days intermittent low use with low screen brightness and 3g on, wifi on makes no difference in my experience.

I just hope it lasts to the end of they day as i charge it nightly.
 
Check the pos setting known as Push and make sure it's off. I recall having Push set to On a while ago so I could use googols calendar sync. The end result was me having to charge my phone around 2-3 times a day.

I was then told by a friend that with push switched off, the iphone calendar app will just auto-sync upon launch and it did.
 
Got through all of today with push enabled and background notifications on (testing AIM beta for Apple) and I've only used 25% battery. I think maybe the phone just needed a discharge/recharge to get it's bearings. We'll see how it is at the end of tomorrow.
 
As of late last night I am now running 3.0GM on my 3G too. I had a good look around the revised Settings app and noticed that my Yahoo and Google Sync settings were set to Push. On my previous 2.0 firmware I had set those to fetch, so I did just that last night.

Today will be the first solid test of 3.0 on my phone. I'm already struggling just looking at a non-jb'd springboard though lol
 
I hope you realise by installing 3.0 GM your phone is locked in to DEV mode.

Even a full restore in iTunes will not alter that. Of course, it doesn't matter if you're a dev :p

No it isn't; 3.0 GM is upgradable to the general 3.0 when it is released..

This version of iPhone OS 3.0 should only be deployed on devices dedicated for iPhone OS 3.0 GM Seed software development. By installing iPhone OS 3.0 GM Seed software on your Authorized Test Devices, these Devices are permanently “locked” into testing mode and cannot be restored to an earlier release of iPhone OS. Bear this in mind before installing the software.

^A workaround for that already exists.

So far today battery life has been equal to the 2.0 firmware. I'm at work atm and since removing it from the dock at 5am to head to work, it is at present (12:36) sitting at 89%. This is with Push set to off on both google and yahoo mailboxes that support it.
 
I remember reading on TheiPhoneBlog that there is also a "chance" that you won't be able to upgrade to the public 3.0 when it comes out =\

Load of rubbish. DFU mode and Shift + Restore and you can restore to anything.

To the OP, try turning off Push, and recalibrate your battery meter (charge to 100% run until it turns off, then recharge again until full).
