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.

You surely have something using the push services behind, maybe another mail account ? This socket is not closed if you have mail running in the background. You must kill it.

Anyway: I would not worry about that, just take care of having logged off the itunes account from settings-store on the iphone and the battery drain should stop.

The bad thing is not the push.apple.com by itself, but its huge & unauthorized use that the appstore does when logged in.

I seemed to have solved my issues with battery drain earlier today. It's a little different approach taken by those in this thread.

First, I closed all background applications. There were dozens in the background list going back months. I don't know if this fixed anything, but I closed them all anyway.

Second, what I think really made the difference, is I disabled Ping. I don't use it and read on a CNET post that it was causing problems. To disable it go into Settings >> General >> Restrictions (you'll have to enable it and provide a new passcode if it is off) >> turn off Ping.

It's been almost 6 hours since I did this and I've only lost 1% of charge, even with some moderate use of the app store and web browsing. Definitely an improvement of what I was seeing on v4.3

thanks for your solution, but it did not work for me,,,,
I close all the background apps, turn off Ping, turn off gamecenter functions, turn off push notifications, and sign out app store.
there is alway the green light in Netstat...

after 1 hour's use, battery dropped to 75%,,,,, after 1.5 hours, it is now below 70%,,,
and my iPhone is WARM (or HOT),,, 4.2.1 was COOL (or COLD)

there is nothing I can do now, only waiting for Apple's next iOS update....

I have tried this method of getting rid of the push.apple.com running in the background. No matter what I do it remains there (in the idle mode). I'm starting to think this cannot be the cause of battery drain.


I am sorry for you; what I suggested here seems to be the solution for many users.
There are also few users on the ITA forum who seem to be in your same condition, no joy. This is really ugly because all the devices should behave in the same way but it seems this is not the case.
I will keep you posted if any other suggestion comes out.

Hi,
For the last few days I have had the very hot battery drain. I looked on most forums but most of the answers were about switching off items that increase battery drain. As I had everything already off on my iphone it obviously was not the answer. What did appear to be reasonable was that something was running in the back ground which I could not see.

I downloaded Xsysinfo, a low cost app that shows running processes. One of the settings is clean memory at launch and a deep clean option. Having run this today my iphone is back to normal.

It may help you or it may not. It certainly helped me although for how long I have no idea:-)

Will do.

For interest my iphone is still at 100% after 4 hours whereas previously it would be almost dead by now.

Note. I have everything turned off as stated previously. I only switch on wifi, 3G, notifications and locations as and when needed. My email is manual fetch. I have to operate this way to get more than two days from the battery as I live in an area of poor signal strength.

here is what i know my battery life dropped in half after updating.i am attempting to follow this and fix it. i will not update again. i thought i bought a phone a smart phone not a fricken PC that i was going to have to be a computer person to have own and operate.i thought that when you closed the app by pushing the home button it closed and stopped data usage?i thought i loved this phone but it is becoming a love hate thing
