Battery goes down incredibly fast after 3.0 update?

THIS IS NOT SIMPLY A PUSH PROBLEM! Many of us are using push accounts with no problems. It is a PUSH+ problem, where something, probably an app such as IM+ or similar apps, which use push, are causing the problems. Check for any messaging apps you may have that utilize push, even when not open. Delete them for now. Maybe a 3.0 version of the app has not been released or maybe there's a bug where it doesn't play well with 3.0.

It's the same Push, OS 3.0 just made it available for third party app developers to use.

I got myself a new 8GB iPhone 3G last friday. I activated it and updated to 3.0 since it shipped with version 2.1
I added an exchange account to check every 15 minutes, and installed a couple of applications.
I let it drain it's battery fully by using it for movie playback.
On monday it was time to take it to work, replacing a SE p1i with a claimed battery life of, talk time 3 hours and 30 minutes, standby 350 hours on 3G network.
Battery was dead 11 o clock !! My trusty old p1i almost allways survived the day.
Next day, I turned location off, dimmed the display etc etc.
Battery dead completely 16.00. No other use than mail and talking.
Today I have turned off 3g, turned off airport ask to join off, mail is set to manual.
It seems I have 70% left now after three hours of use, but today I have only used it for talking 5 minutes.
Tomorrow I will remove the mail account completely to see if it will last a full work day for me.
Next day I will remove all third party apps thatI have installed. I thought the iPhone didn't support multitasking so how can they take cpu?
It would be nice with a "Activity control" on the iPhone to make sure there are no dead processes taking 100% cpu.

Hi. I KNOW now that IM+ 3.1 was the problem for me.
After updating to 3.1 the battery went down very fast.
I deleted IM+ (bought it a few days ago... 😟 ), rebooted
the iphone and all is well 🙂

btw. 3G on, push email (1hour) on, location services on...

br, -d-

My 3G is also having short battery life problems since I installed 3.0. How can I help apple troubleshoot this problem?

Same problem here; after the 3.0 bug update, and it did not happen immediately. Performance began deteriorating over a week after software update and battery overheating and reduced battery life exhibited.
No third party applications in use for messaging, email, web, etc.
Won't be changing settings or turning off features.
Will be returning phone, again and again and again until fixed.
Never set out to buy an Apple paperweight.

I totally understand! What's the point of having a smartphone if you cannot use any of the features...Called Apple Tech Support and I told them the same thing and they're like that's impossible to have everything on and get good batt. life. RIDICULOUS! So I guess I'm paying over $100 monthly for NOTHING!

Battery overheating with minimal use is more noticeable than reduced battery life on my phone. 5 minute phone call and it is hot to the touch.

I just surfed for 1:30 and the battery is already down to 50%. I think that's really poor. It doesn't really drain much when the device is in standby.

Is it usual that surfing drains the battery that extremely fast?

Well, it depends on signal strength, WiFi vs 3G and what else was running. The 3G Internet spec is "up to 5 hours", so after 1.5 hours you should be down only 30%, unless you had less than 5 bars. If you were at 1 bar that might be reasonable.

BUMP
