Solution for iOS 4.3 battery drain

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.

Thanks so much for the clear description and clear directions for fixing it. I've been round and round with this with apple by phone, at the genius bar, etc. thanks for your help.

I've read through many of these posts and I can avoid going to the App Store, but I'd like to know about the e-mail settings. I have my Gmail set up using Google Sync (Gmail through the Exchange mail setup) and I have push enabled. I am willing to take push off until 4.3.2 comes out and just set it to fetch every 15 minutes, but will that eliminate the terrible batter drain or not? I'm not willing to go without my Google Sync setup as all of my contacts are on the Google servers. Secondly, I don't want them stored locally, in case I lose my phone, I won't have any new contacts I put in. Can someone shed some light on whether or not this fix will work when using Exchange or Google Sync?

Well, the only thing that works is turning off wifi and cellular data. So I can't get mail, update my calendar, or really do anything. I've followed all suggestions above, but this is the only thing that keeps the battery from draining at a terrific rate and keeps the phone from heating up. I worry about damage to the battery with all of this. When I can I keep it plugged in to read my mail, etc. When will Apple fix this???? Or at least communicate with us about it?

I also have the battery issue after updating to 4.3. I've turned off all services that were suggested, and used Netstat to monitor the push.apple, and after turning off all of my email accounts, it no longer is listed. The battery is still draining, although not nearly as fast.

I have 4 gmail accounts set up as an exchange account, and I was told if you delete them, and then recreate them, that fixes the issue. I would think that if I turned off the mail, that this would give me an idea of whether or not that would fix the issue since my mail is currently disabled. It is draining less, though, so I think it definitely helps. So those of you who have gmail set up as an exchange email account, just delete it and then recreate it. You won't lose any data, because it's all on Google's servers.

But to get my battery life back to 100%, I'm going to give draining my battery until it dies, and then charging it back up to 100% a shot and see if that fixes it.

Also, try charging your phone to 100% via your AC charger, leave it plugged in, do a soft reset, and then sync with iTunes once. I'm going to give that a shot.

Found that here:

BTW, turning off my mail definitely did not fix the issue. It went from 30% to dead in an hour. I did help it along, though, by playing a racing game, because I also wanted to try the fix where you let it die and then charge it back up to 100%. If doing both of these things fixes it, I know I won't be able to tell which one did it, but I don't care. I can't function with a battery that drains so fast, when right before I upgraded, it was fine.

That did it for me. Finally! Tried all other suggestions, but all I got was a marginal improvement with everything off (push, notifications, appstore, etc.) Now my 3GS battery life is back to normal (before the 4.3 update).

Why couldn't Apple just advise the users to do this after the update?

Thanks labachlr!

Does the iOS 4.3.4 update solve this background traffic issue?

I would like to share some thoughts on the subject.

All who are interested, why have to go out of your account appstore.

I installed the diagnostic profile for apsd. I got more information, but it did not help me solve the problem. Perhaps together we will find a solution.

It is known that every 10 minutes apsd shows network activity, if not out of the appstore. I will publish here part of the log file:

http://www.ontext.info/44197

I understand that every 10 minutes and the timer is keep-alive connections. But what are they for, if there is no subscription for the automatic loading of applications and books. It is not clear why we need these keep-alive connections. Let's understand this?

Thank you! this solved 2 problems for me. One was the battery issue and the other when I shut all the push down also solved the problem with the greyed out icon i was getting that was stuck on "waiting" for over 3 weeks now. Again, Thankyou!
