Hi all,

first of all thank you to all the community of iphoneitalia.com forums.
Thanks to the contribution of many users yesterday night the solution finally came out.

Let us go to the main subject.

1. How to identify if you have the issue:

-disable any push in your device: notifications, mail, find my phone, whatever might create any data traffic related to push activity. Disable gamecenter, ping, facetime in system restrictions.
Then close any app in the background.
In such conditions you should not have cell data consumption (=0 kb consistent along hours if you do not touch the phone)

Symptoms of illness: cell data usage goes up even if the phone is in stand by; usage time goes up even if you are not using the phone; battery consumption looks ugly comparing to previous iOS.

How to certify your feelings:

-download an app called netstat from the appstore, it is free
-run it and check if you have push.apple.com in the active sockets (=green pin)

If you have it even with all disabled as above described, you are really having the problem, they are not only feelings or dreams.
Something is constantly acting along this socket, your data usage will go up even if the phone is in standby, the usage time will do the same.

2. How to fix it

After many and many attempts some users found that the responsible app is the app store.
Simply go to settings->store and EXIT from the account.
Run Netstat again and you will see that push.apple.com is not active anymore.
Check data volume and usage time again and you will see that they are not going to increase anymore.

At this point you can activate again your notifications, mail and what you usually need, your power and data consumption will go back to the values you were used to before upgrading to iOS 4.3.

If you login into the appstore again you will face the problem again.

Of course it is not THE solution but it is an acceptable workaround while waiting for a fix from apple.

Final message:

to all the users: try this and enjoy your battery again

to the Apple engineers: please read, learn and fix

Ciao.

    I've also followed the same, and still appear to have push.apple.com active even after signing out of the store.

    Power cycle your iPhone after signing off App Store.. the push.apple.com now gone from active connection list. Will see what this does.

    This could be the Email app being dodgy, try killing it if you have it open and see if that clears them, if not, do what people say on here and clear syncs by enabling all the toggles on the account (Calendar, Notes and Email) then open each one for around 10 seconds, then kill all 3 and re-toggle just email.

    Worked for me, but I still have to kill the email app to close the push and imap connections

    @sdmaino

    Remember that if you leave mail application in background, connection to push.apple.com stays always active. You have to Close it because after you use mail the status of the connection is always "established".
    The main problem is that the connection to push server will always use 3G link, also if WiFi is active!
    To eliminate definitely this problem the user should switch off "Cellular Data".

    bye

    Ditto on the Mail app causing the push and IMAP sockets to open and stay open (Gmail mail account is set up for no fetch, no push). If WiFi is off both of those sockets are on the cellular connection and never seem to close, even when the phone goes to sleep. If WiFi is on, the IMAP socket will be on Wifi and will get killed when the phone goes to sleep. The push socket will remain open (and if that socket was on the Wifi connection it will jump over to the cellular connection when the phone sleeps). Forcing mail closed causes both sockets to close. If you turn on fetch, both sockets usually come back even if you kill the Mail app.

    Does anyone have an iPhone with iOS 4.2.1 to see if the same sockets appear? I can only compare to my 2nd Gen iPod Touch running 4.2.1. On that device the push socket never appears when using Mail and the IMAP socket goes away after about 2 minutes, even with Fetch turned on.

    I don't know if these sockets specifically are causing the battery drain. Would be nice to get info from an iPhone with iOS 4.2.1 to see if exhibits the same socket behavior.

    Awesome. Charged my iPhone 4 this morning and after 30min it was down to 96% from 100%. After reading this and logging out from iTunes, I charged it again to 100%. Gone 4 hours and still 100%. Thank you very many.

    Users on iphoneitalia.com forum tested this on iphone 4 running iOS 4.2.1 and confirmed that the socket does not appear on it when all is disabled as described in the first post.

    Something in iOS 4.3 broke it.
