Gyver, I think we know how to turn off the push function. But seriously, this has got to be a firmware problem. Most of the phones were fine before the update.

Whats the point of buying a smartphone if we have to turn off all the services? All the suggestions only point to turning this off, turning that off which really defeats the purpose. I don't know how you guys can accept buying a phone that markets itself as a do-it-everything phone which after you purchase, you are suggested not to use any of that. Maybe we shouldn't even turn on the phone, just let it sit in our pockets to look pretty.

I had a iPhone 3G and had most services turned on, the phone could at least last me for a day. Ever since I got the 3GS, the battery has been horrible. Even with everything turned off, the phone is depleting 1% every minute, for just sitting there with the screen locked.

I've restored the phone, redownload the firmware and reinstalling, create a new profile for the phone and nothing worked. It must be the 3.0.1 firmware.

Whether the battery is the same or not, should not be a concern for customers like us. They have marketed the battery life everywhere and now it seems to fall so short of it. I'm quite disappointed by Apple. You may be right that due to the upgrade of hardware, the battery might drain faster, but let's not forget the OS is also upgraded, which can also manage power more efficiently and effectively. Just like Windows and Mac, why is it both machines have similar hardware but Mac can run it better and with less problems?

Update:

I found that if the signal is stronger, the battery life improves dramatically. I switched out my sim card today to a different carrier and my battery life was back to normal.

It IS possible. Its like having to shout louder to someone far away as oppose to talking to someone just beside you. It is a very logical theory.

I turn Location Services On, Push, and 3G on. My battery can last me for at least 1.5 days. It used to suck, but changing the carrier solved it for me.

Anyway, you can leave the iPhone charged for as long as 1-4 days. The battery doesn't overcharge. This is why all the speakers for iPods and iPhones provide charging capability, so they can sit there for a long time.

He probably doesn't use his phone as heavily as us which explains the long standby time versus usage time.

Anyhow, I wonder why would ppl always wait till their battery is flat before charging? It wastes a cycle of the battery life.

Thats exactly what I meant what. But so many people are waiting till its empty before charging. It would waste a cycle cos they get the chance to charge but they dont

That can't be right. We don't hear many stories of new iPods having problems like that do we? Nor the new Macs. It can't be just because they are new.
