    I had the same problem with my iPhone 3g. I fixed this by doing a full restore, reloading my backed-up info and then resetting the phone. This has solved the battery drain problem and the constant transmitting problem that some people have reported.

    Same problem here. tried everything to fix this, deactivating push helped a bit only.

    I fixed it by deleting ALL email accounts and recreating them from scratch.

    Back to normal

    I'm having the same problem since the 3.0 update. To add to the battery drain prob, my sms's aren't reaching me. Only if i switch off the phone and switch on again i get the msgs. Theres nothing wrong wit the sim coz it works ju fine on other mobiles. Has anyone faced this prob?

    I have the same problem. I usually have everything turned on, wifi, bluetooth, push etc...Never had a battery draining so fast before 3.0 upgrade.

    I found a possible cause, at least for me.

    I did some testing with reset and restores. After a complete reset of EVERYTHING. I didn't do a restore and manually went in to re-create my email accounts. I added Yahoo, then Gmail. Battery was fine. Lasted full day with no charge and it was still at 75%.

    Here's where I think the problem is. After another full charge, I lastly add my company EXCHANGE email account into the phone. Immediately after 2 hours, phone battery was done to 50%. I used to also have this account on my phone prior to 3.0 with PUSH with no problems.

    Conclusion: Fast Battery Drain Problem Linked to having a Exchange Account w/PUSH attached to phone.

    Would that it were that simple!. I had the problem in an original iPhone. Deleted my Exchange account, then added it back, and the problem went away. 2 other 3G iPhones in my office that also use Exchange with ActiveSync have updated to 3.0 and have not had any problems. So Exchange may be necessary, but is clearly not sufficient in itself to cause this problem. Which is probably why it wasn't caught in pre-release testing.

    False, i haven't an exchange account with push mode enable. Juste a simple gmail with push to disable, and the problem is the same !!!!!!!!!!!

    You're right. I have the same problem. I made a clean restore and it has the same problems. Hope Apple will do something for that issues.

    I've had the same problem. Whilst "Push" notifications where active my battery wasn't even lasting 24hrs! So I've turned them all off (that was all of 2 apps) and now it's back to normal.

    same issue here:

    when I turn on the Push notification, the phone is warming up very quickly.
    Battery life goes down very quickly, I was using the Ipod Application for app. 5h and the voice recognition feature a couple of times. then the phone was compleatly dead (less than 6h total)
    I have a not Data enabled mobile phone contract. maybe this is the root cause?

    after switching off the Push feature, the Phone is cooling down, normal battery life after that.

    I will double check this with my Data plan Simcard with enabled Push notification.

    kind regards

    Same here hot & drains in 3/4 hours afther the update 3G 16gb
    An Vodafone employe here in Greece told me it is probably a problem with the push e-mail.
    They recommended me to tun it of for now.
    Many here have the same problem.

    Continuing from my last post.

    I tried again to add the Exchange account, this time turning off the push, ONLY using fetch every 1hr JUST for the Exchange email account. From a full charge the phone just lying there, the battery dropped to 20% in 5 hours.

    However without the Exchange account, it ran a whole day with push on my other email accounts and light usage the battery remained a hardy 80%-90%.

    Apple Developers PLEASE find a solution!

    Same here. iPhone 3G, without Push email function, but with normal App Push usage (Hey There). About 30% less battery life

    I was playing around with Push Notifications this morning after a fresh 100% recharge. I was testing Beejive and AIM.

    Now, 1.5 hours later, I checked my phone and it was down to 50%! I'm charging it now and it's slowly going back up. I'm gonna turn off push notifications and see if it happens again.

    I've always had mail notifications pushed every 15 minutes, even with my 3G, so I don't suspect that's the problem.
