iOS 4.3 drains my battery and does not auto lock

After installing iOS 4.3 on my iPhone 4, my phone has dropped 20% battery usage in 20 minutes, doing nothing. It also does not auto lock anymore, it is set to 1 minute. I tried to reset the phone and no change. The phone is warm, indicating some process is running constantly. I have made no change before the upgrade. Before the upgrade everything was working fine, after the iOS 4.3 upgrade the battery is draining REALLY fast and it does not auto lock.

Any ideas?

iPhone 4, iOS 4

My experience is, Apple will not sort this out or offer a solution aside from restoring your iPhone as a new device. Have they ever admitted that their batteries have problems? Not that I'm aware of. I know I'm ranting here, but in this world of unbelievable technical devices that can do so much, why can't a rechargeable battery be created to power these devices? It blows my mind every time. If restoring as a new device is their typical solution, why can't there be a way to save app data separately for each app, rather than through an iTunes backup? The closest thing I've seen is software called iPhone Explorer which lets you browse your iPhone file structure. Although I wasn't sure what data I needed to save for each app. I guess I have to contact the 50 or so developers of all my apps to ask what I need to save. Sorry for going off on a tangent.

Something is definitely wrong. Now my usage time is the same as my standby time.

This has happened before. Usually it was related to an exchange account constantly checking for something.

I've tried to trace this battery drain by methodically turning each service off and later checking the usage time. So far I've determined that it isn't spotlight search, notification, email, contacts, calendar, push, wifi, location services... still checking.

This *****.

Just read this on another forum about battery drain on 4.3:

[QUOTE=SomeDudeAsking;12120675]Guys, I know what is causing your battery issues. It is the new Ping curse that Apple integrated deep into iOS 4.3 and is turned on by default. It uses push notifications so it is always running and using data. To disable it, go to:

Settings->General->Restrictions->Ping and kill the beast.[/QUOTE]

So go into the restrictions it will say off initially but go into the menu and it shows them all on and in blue but greyed out.

Not sure if this will work but worth a try.

hello
i m experiencing a weird thing (probably related to this battery draining)
I disabled every notifications, closed all the apps, manual email, restrictions on ping, game center and facetime etc, but there is always an unwanted data traffic. Few kbs but often , meaning many connections. I compared my ip 4.3 with my gf's 4.1 and there is no data traffic there (without all the restrictions i had to use on mine).
I swutched off cell data and i noticed that every time i open the SMS app, i get a popup wartning me they are off as there is always something needing connection...i just dont know what it is....

This is a definite 4.3 problem but it isn't yet clear whether or not it's a "feature" or something else. I noticed this right away but it took 3 days or so before I finally thought hey something's not right at all. I started today at 100% battery and after only 5:45 standby, one three minute call and otherwise normal use (for me) I was at 14%. I rarely hit 20% in the same day ... rarely.

I've turned off Ping so let's see if that's it.

I tried turning off Ping, but that has not worked for me. To repeat my problem, this has been going on since iOS 4.2.1 for me. iOS 4.3 did not fix the situation. I keep complaining about having to restore my iPhone as new, but I think it is a valid complaint. It is a big pain to set up EVERYTHING on your phone the way you had it. I don't know why I have to do this when I've only had this device since Sept 2010. It doesn't seem fair to have to restore a 6 month old iPhone (I know, nothing is, and Japan has bigger issues than me right now).

One thing I've noticed compared to when my battery was normal is I can actually watch it drop a percentage point. Never once did I see that number drop prior to installing iOS 4.2.1. And this is when the phone is sitting there doing nothing.

So, I'm going to post pictures of what my phone did yesterday. Mind you I didn't use it to make one phone call or text message. I have minimal notifications running, and I repeatedly closed apps running in the background. I was on wifi about 80% of that time. Didn't really play any games. Just checked e-mails, listened to some music, edited some photos. Nothing you would call heavy use. I'm posting links from my SugarSync account. The first one is a pdf of all processes running in the background when you turn your iPhone on and before you run a single app. The next link is a pdf of screen shots of my usage data, showing I got about 6.5 hours of usage plus 43 hours in standby on a full charge. This is without making phone calls or texting! Totally unacceptable.

(NOTE: clicking the above links will download the pdf file to you. I'm not sure how to get SugarSync to let people just view the doc in a web browser... if that is even an option)
